Why Understanding Your Home’s Attic Ventilation Matters

Attic ventilation is one of those home features most people never think about — until it becomes a problem. Unlike a leaky faucet or a cracked window, poor attic ventilation doesn’t always make itself known right away. But when it does, the consequences can be costly and sometimes dangerous. Proper attic ventilation is about more than just keeping the attic cool in summer; it’s about controlling moisture, extending the life of your roof, improving energy efficiency, and protecting structural components of your home.

So what exactly is attic ventilation? In the simplest terms, it’s a system that allows air to flow through your attic space so that hot, moist, or stagnant air can escape and be replaced with fresh air from the outside. A well-designed ventilation system uses intake vents (typically located at the soffits or eaves) and exhaust vents (such as ridge vents or gable vents) to promote continuous airflow. Think of it like the lungs of your house — without proper airflow, heat and moisture build up, leading to a host of potential issues.

One of the most common problems caused by inadequate attic ventilation is excess heat. In warmer months, heat from the sun can make attic temperatures soar well above the outdoor temperature. This excess heat transfers into the living spaces below, forcing your air conditioning system to work harder to maintain a comfortable indoor temperature. The extra strain on your HVAC system can lead to higher energy bills and potentially shorten the lifespan of your cooling equipment. On the roof itself, high attic temperatures can accelerate the degradation of shingles and other roofing materials, which could mean costly repairs or a premature roof replacement.

In colder climates, attic ventilation plays a different but equally important role. Warm, moist air from the interior of the home rises naturally and can enter the attic if not properly vented. When this warm, moist air meets the cold surfaces of the attic in winter, it can condense and lead to moisture accumulation. Over time, this moisture can create conditions conducive to mold and mildew growth, wood rot, and deterioration of insulation. In some cases, moisture in the attic can lead to ice damming on roofs, where melting snow refreezes at the eaves and causes water to back up under shingles and into the home.

A well-ventilated attic also helps regulate moisture levels year-round. Even in regions without extreme temperature swings, everyday activities like cooking, showering, or doing laundry introduce moisture into the home’s interior air. Without adequate ventilation, that moisture can find its way into attic spaces and compromise the performance of insulation, degrade wood framing, and reduce indoor air quality.

So how do you know if your attic ventilation is working the way it should? Some signs to watch for include unusually high attic temperatures in summer, ice dams in winter, visible mold or mildew on attic surfaces, damp or wet insulation, and unusually high energy bills. While some of these signs can be caused by other issues as well, they are worth investigating and may warrant having a professional inspection to assess your attic’s ventilation and overall condition.

Improving attic ventilation doesn’t always require a major overhaul. In many cases, potential solutions can be as simple as ensuring soffit vents are not blocked by insulation, adding or upgrading ridge vents, or installing additional intake or exhaust vents to balance airflow. Every home is different, and the right ventilation strategy depends on a variety of factors including roof design, climate, insulation levels, and existing vent placement.

In conclusion, attic ventilation is a critical but often overlooked component of a healthy, efficient home. From reducing energy costs to protecting the structure of your home and improving indoor air quality, the benefits of proper ventilation extend far beyond the attic space itself. If you’re unsure about your home’s attic ventilation or have noticed any warning signs, consider having a professional inspection to identify potential issues before they become costly problems. After all, prevention and early action are at the heart of responsible homeownership.

Winter Power Outage & Home Safety Preparedness Every Homeowner Should Know

Winter in southwestern Pennsylvania can bring more than just cold temperatures — it can bring snowstorms, ice, and the very real possibility of power outages. When the lights go out and temperatures drop, being prepared isn’t just convenient… it’s essential for safety, comfort, and protecting your home.

Here’s a practical guide to help you prepare your home and family for winter power interruptions — based on real inspection experience and common issues we see in homes throughout Cambria, Somerset, Westmoreland, Blair, Indiana, and Bedford Counties.

1) Know Your Home’s Electrical System

Your home’s electrical panel is the heart of your power distribution.

Label circuits clearly. Knowing what breaker controls what can save time and stress during an outage.

Inspect panel condition. Loose connections and corrosion are fire hazards and more likely to show issues when systems start under load after outages.

Pro Tip: If you notice flickering lights, warm breakers, or rust at the panel, have a licensed electrician evaluate it before winter’s peak.

2) Plan Safe Backup Power

Whether it’s a portable generator or a whole-home standby system, backup power can provide peace of mind — when used safely.

Portable Generators

Never operate indoors or in garages — deadly carbon monoxide can accumulate.

• Use heavy-duty outdoor extension cords to power appliances.

• Keep fuel stored in approved containers, away from heat sources.

Standby Generators

• Installed by a professional.

• Automatically switch on when power fails.

• Must have a transfer switch to isolate from utility lines and prevent backfeed.

Pro Tip: Test your backup power before you need it — snowstorms aren’t the time to discover dead batteries or low fuel.

3) Winter Emergency Supply Checklist

A short power outage can become an emergency without proper supplies.

✔ Flashlights and extra batteries

✔ Portable battery chargers for phones

✔ Non-perishable food and bottled water

✔ Blankets, warm clothing, hats/gloves

✔ First-aid kit and medications

✔ Battery-powered radio or NOAA weather alert radio

Pro Tip: Keep supplies in a central, easy-to-reach location and refresh them each season.

4) Stay Warm Without Electric Heat

If the furnace won’t run, make a plan.

Fireplace or wood stove: Ensure the chimney is clean and damper works.

Kerosene or propane heaters: Only use outdoor-rated units with proper ventilation.

Layering: Insulate yourself before heating the space — extra blankets, warm socks, and hats make a huge difference.

Never use a gas oven or stovetop as a heat source — this can lead to carbon monoxide buildup.

5) Protect Plumbing During Outages

Loss of heat plus cold nights can freeze pipes quickly.

• Let faucets drip slightly during extended outages.

Open cabinet doors under sinks to allow warmer air to circulate.

• Insulate exposed pipes in basements and crawlspaces.

Pro Tip: Know where your main water shut-off valve is — if a pipe bursts, shutting off water limits damage.

6) Roof & Structural Snow Load Awareness

Heavy, wet snow can add serious weight to roofs.

• Visually inspect roofline for sagging or uneven snow build-up.

• Use a roof rake from the ground to remove excess snow (never climb on icy roofs).

• Look for ice build-up near eaves which can lead to ice dams and water intrusion.

** Pro Tip:** If snow accumulation is significant after an outage or storm, call a professional before it becomes a structural problem.

Final Thoughts

Winter power outages are unpredictable, but your home and family don’t have to be unprepared. With a plan, proper supplies, and safety-focused practices, you’ll stay safer and more comfortable when Mother Nature tests your preparedness.

If you’d like a professional home evaluation that includes electrical system readiness, emergency power considerations, and winter safety insights, Hill Property Inspections can help.

Carbon Monoxide Risks: How It Enters Homes & What to Inspect For

Carbon monoxide (CO) is called the invisible killer for a reason — it’s colorless, odorless, and tasteless, yet responsible for hundreds of preventable deaths each year in the United States.

As temperatures drop and furnaces, fireplaces, and space heaters kick into gear across Pennsylvania, understanding how CO can infiltrate your home — and how to prevent it — is critical for every property owner.

Here’s what Hill Property Inspections recommends you know and check before winter is in full swing.

1. What Exactly Is Carbon Monoxide?

Carbon monoxide is a byproduct of incomplete combustion — meaning when fuels such as natural gas, propane, oil, coal, or wood don’t burn completely.

Every gas furnace, boiler, water heater, and fireplace produces some amount of CO, but in a properly vented system, those gases are safely carried outdoors. Trouble starts when vents, flues, or burners malfunction, allowing CO to leak indoors.

Pro Tip: Even small CO leaks can build up quickly in today’s tightly sealed homes with limited ventilation.

2. The Most Common Sources in Homes

Many homeowners assume CO only comes from furnaces — but there are several common culprits:

Gas furnaces and boilers (cracked heat exchangers, blocked flues)

Water heaters and gas dryers

Fireplaces and wood-burning stoves

Gas ranges or ovens (especially if used improperly for supplemental heat)

Attached garages (vehicle exhaust seeping through door gaps or shared framing cavities)

Portable generators or space heaters used indoors

In multi-unit or mixed-use buildings, CO can even travel between units through shared chases or return air systems.

3. Warning Signs of Potential CO Problems

Because CO itself can’t be seen or smelled, pay attention to indirect warning signs of combustion or ventilation issues:

• Yellow or flickering burner flames (instead of steady blue)

• Soot or scorch marks around furnace panels or vent connections

• Persistent condensation on windows or cold walls near heating appliances

• Unexplained headaches, dizziness, or nausea among occupants

• Smoke smell or backdrafting from fireplaces or water heaters

If these symptoms appear, leave the building immediately, call 911, and have the property evaluated before returning.

4. How to Prevent CO Buildup

Preventing carbon monoxide issues starts with proper maintenance and awareness. Follow these steps every heating season:

1. Schedule an annual furnace or boiler service — including a combustion efficiency and draft test.

2. Inspect all vent pipes for rust, gaps, or loose fittings, especially near elbows or joints.

3. Check chimney liners in older homes; deterioration or blockage can trap exhaust gases.

4. Never use ovens, stoves, or grills for heat.

5. Keep flues clear of bird nests, leaves, and snow.

6. Maintain adequate combustion air. In sealed basements or mechanical rooms, add venting or louvered doors.

Pro Tip: Negative pressure from exhaust fans or tight building envelopes can reverse flue draft — a common cause of hidden CO migration.

5. Detector Placement and Testing

Every home should have at least one carbon monoxide detector per floor, ideally near bedrooms and adjacent to mechanical rooms.

Avoid placing detectors directly above fuel-burning appliances, which can cause false readings.

Replace detectors every 5–7 years, or per manufacturer’s instructions.

Test monthly and replace batteries each daylight saving change.

Interconnected or smart detectors are best for multi-level or multi-unit properties.

6. Inspections & Professional Testing

A professional home or commercial inspection can reveal conditions that promote CO buildup — including improper vent pitch, disconnected flues, blocked chimneys, or shared ventilation paths between appliances.

At Hill Property Inspections, our team uses combustion analyzers and infrared thermography to spot exhaust leaks, confirm vent integrity, and verify proper airflow in basements and mechanical rooms.

We also check whether detectors are properly placed — something too many property owners overlook until an emergency occurs.

Final Thoughts

Carbon monoxide is silent, but the risks are very real. A few minutes of maintenance and an annual inspection can protect your family, tenants, or employees from one of the most preventable household hazards.

Ensure your home and family are safe from carbon monoxide and other unseen hazards this season by scheduling a thorough inspection or walk-through consultation:

Pre-Winter Checklist: What Home Systems to Inspect Before the Freeze

As fall turns to winter here in southwestern Pennsylvania, even a few overlooked maintenance items can lead to costly surprises. From frozen pipes to failing furnaces, now is the time to inspect and prepare your home’s major systems before the first real cold snap hits.

Here’s Hill Property Inspections’ professional pre-winter checklist—drawn from years of inspecting homes across Cambria, Somerset, Westmoreland, Blair, Indiana, Bedford and surrounding Counties.

1. Roof & Attic: Stop Leaks Before They Start

Your roof is your first line of defense against snow and ice.

Inspect shingles for curling, cracking, or missing pieces—especially near valleys and chimneys.

Check flashing around vents, skylights, and penetrations. Even small gaps can lead to leaks when ice accumulates.

Look inside the attic for dark stains, damp insulation, or visible daylight—these are red flags for air leaks or roof damage.

Verify ventilation. Proper airflow through soffit and ridge vents helps prevent condensation and ice damming.

Pro Tip: If you can see frost or moisture on attic nails, your ventilation or insulation is out of balance.

2. Gutters & Downspouts: Direct Water Away

Clogged gutters can create ice dams that force melting snow under your roof covering.

Clear all leaves and debris. Flush the system with water to ensure flow.

Confirm downspout extensions discharge at least 4–6 feet from the foundation.

Inspect grading. Soil should slope away from the house—at least 6 inches over the first 10 feet.

These small adjustments prevent foundation seepage and protect basement walls through the wet freeze-thaw season.

3. HVAC System: Clean, Service, and Test

Cold weather exposes weak heating systems fast.

Replace furnace filters and ensure registers are open and unobstructed.

Have your furnace or boiler serviced by a qualified technician. Annual cleaning keeps efficiency high and reduces carbon monoxide risk.

Test the thermostat and inspect vent connections for rust or gaps.

Consider an infrared scan (available with Hill Property Inspections) to check for air leakage and uneven heat distribution.

If your system is older, now’s also the time to budget for an upgrade or backup source.

4. Plumbing & Water Systems: Prevent Freezing

Frozen pipes are among the most common—and costly—winter emergencies.

Disconnect garden hoses and drain exterior faucets.

Insulate exposed pipes in unheated crawlspaces, basements, or garages.

Locate your main water shut-off valve and make sure every adult in the household knows how to use it.

If you have a sump pump, test it. Pour water into the basin and confirm automatic operation.

For homes on private wells, ensure the well pit or pressure tank area is insulated and protected from drafts.

5. Safety Devices: Test and Replace Batteries

Smoke and CO detectors: test each unit and replace batteries.

Fire extinguishers: ensure at least one is rated for A-B-C use and stored where it’s visible and easy to access.

Dryer vent: clean out lint buildup to reduce fire risk.

6. Exterior & Entry Points: Keep the Cold Out

Seal gaps around doors and windows with weatherstripping or caulk.

Inspect exterior lighting for proper operation—shorter days require dependable fixtures.

Check sidewalks and handrails for damage before freeze events make repairs difficult.

Final Thoughts

A pre-winter inspection is more than a checklist—it’s preventive insurance. By tackling these simple tasks now, you protect your roof, foundation, and comfort all season long.

If you’d rather have a certified professional evaluate these systems for you, Hill Property Inspections offers comprehensive pre-winter assessments, infrared scans, and maintenance inspectionsthroughout southwestern Pennsylvania.

Maintenance Recommendations

Homeownership involves quite a bit more maintenance and upkeep than many realize, and knowing what to do and how to prioritize a myriad of tasks over time can seem overwhelming. Below is a list of maintenance suggestions relevant to each titled section, and we hope you find this guide useful!

EXTERIOR: The exterior components act as the “skin” of the structure and a first line of defense against the elements, and all exterior areas and components should be continually monitored and well maintained to ensure the structure is well protected and safe. This includes (in part) maintaining all vegetation at least 1-2 ft from the house exterior, repairing any damage to siding, trim, fascia, soffit and flashing, cleaning moss, algae or other vegetation growth, monitoring the base of cladding and deck/porch posts, ensuring that soil grading is positive (sloped away from the foundation), maintaining exterior caulk, sealant, paint and stain, keeping wood piles at least 30 ft from any structure, sealing any exterior cracks and crevices, repairing any damaged masonry, protecting any exposed, bare or deteriorated wood, and addressing unwanted pest activity.

ROOF & PENETRATIONS: The roof is a crucial first line of defense for the structure and should be maintained in the best condition possible, which includes (in part) continual monitoring of the roof covering for signs of damage, periodic cleaning of gutters, debris and vegetation growth, extension of downspouts across lower roof surfaces and at least 5 ft from basements or crawlspaces or 2 ft from slabs, sealing of any exposed fasteners or deteriorated sealant/flashing, and securing of any loose roof, vent or rain spouting fasteners. If not already present, gutter guards would ideally be installed to prevent accumulation of vegetation and other debris that could hinder proper drainage, and installation of heat cable along eaves is often beneficial for preventing ice damming.

GARAGE: Cracking in garage slabs (concrete floors) is common due to shrinkage or possible heaving, and any cracks should be well sealed and periodically monitored, whether present now or in the future. Attached garages should contain suitable fire separation material, such as 5/8-inch type “X” drywall, between the garage interior and adjoining living spaces, and garage man doors leading to the house interior should be solid and self-closing (fully fire rated) to prevent the spread of fire and potentially harmful exhaust gases (including carbon monoxide) that more frequently occur in garages. Working photo-electric “red eye” safety sensors should be present within 6 inches of the ground at the base of overhead and mechanical garage door tracks, and garage door openers should be connected to dedicated receptacles rather than extension cords. Although not required, any exterior man doors serving garages should be equipped with deadbolt locks to improve security.

FIREPLACES & STOVES: All fireplaces or stoves should be operated with care and safety and continually maintained as needed, and all chimneys should be periodically monitored for signs of damage or buildup. Hearth extensions in front of wood-burning fireplaces should be at least 16-20 inches deep, depending on the size of the fireplace opening, to prevent a potential fire hazard, and the firebox (interior) of a fireplace should be kept clean from excessive ash, soot/creosote and corrosion buildup. For wood-burning or vented units with a damper, the damper and its control should be in good working order to ensure safe exhaust of combustion gases and smoke and to properly regulate draft. Masonry chimneys should be equipped with a flue liner to safely carry exhaust outdoors and a rain cap to prevent unwanted water, debris or vermin intrusion that could lead to possible damage or obstruction. Metal chimneys should be generally free of rust and an appropriate, listed type for the appliance served.

STEPS & RAILINGS: Handrails should exist where there are more than 3 steps (counting landings) and should be secure, graspable, continuous, located 34-38 inches above the front nosing of stair treads, and equipped with vertical balusters (spindles) along open sides that are spaced closely enough together that a 4-3/8” sphere cannot pass between them. Likewise, guardrails should exist at landings 30 inches or higher and should be secure, at least 36 inches (3 ft) high, and equipped with vertical balusters spaced no farther than 4 inches apart. Guardrail barriers should also be vertical, not horizontal, as horizontal balustrades are climbable for small children. The minimum recommended height at stairways is 6’-8” (although lower heights are common in older homes), and stair treads and risers should vary in depth or height no more than 3/8-inch to prevent a potential trip hazard. Stair risers over 4 inches in height should also be closed where there are more than 3 steps, and open risers are very common at deck, porch and basement stairways. Doors should also not open above stairs unless a minimum 3’ x 3’ landing is present, and an enclosed landing or a landing with steps and railings should exist beneath elevated exterior doors.

WINDOWS & DOORS: Bedrooms should be equipped with suitable egress (emergency escape or rescue) windows that are openable, at least 5.7 square feet in size, and no higher than 44 inches above the floor, and working locks are ideally present on bedroom and bathroom doors for privacy – excluding master bathrooms connected to master bedrooms. Windows should not be left open during periods of rain or snow to prevent damage to interior window stools or other materials, and doors should not open above steps unless a minimum 3’ x 3’ landing is present to prevent possible injury. Deadbolt locks ideally exist at exterior doors for added security, and deadbolts should be keyed only at the exterior. Openable doors and windows should operate smoothly, and window and door locks should be properly aligned and functional.

INTERIOR: Monitoring for new or worsening cracks in walls and ceilings, doors or windows that begin to stick, stains that may form on finishing materials, and other signs of damage that may arise at the interior should be common practice. Any such cracks or stains should be well sealed to make further damage that may arise more apparent. Shades/covers should be present at interior light fixtures to protect bulbs, closet lighting should be LED or fluorescent, and at least one receptacle outlet should exist in any hallways that are 10 ft or longer. Periodic monitoring for unwanted pest activity is also recommended, as well as maintaining the interior in a clean and sanitary condition. Cosmetic defects, such as carpet stains, scrapes, dings, markings and the like, do not generally affect safety or durability and are typical of nearly all houses to some extent, but cosmetic issues are ideally addressed for aesthetic purposes.

KITCHEN & BATHROOMS: All kitchen and bathroom caulk and grout will naturally deteriorate over time and should be continually monitored and cleaned, repaired or replaced as often as noticeably necessary – whether in poor condition now or in the future – to prevent moisture intrusion into concealed wall and floor areas that could lead to mostly hidden damage over time. Toilet closet bolts should also be kept tight and capped to prevent loosening and corrosion, adequate clearances should exist around toilets, and mechanical drain stoppers at tubs and sinks should be adjusted as needed to ensure proper function. Shower arms are also ideally surrounded by a waterproof material extending at least 3 inches above the flange to prevent possible moisture damage to walls, and carpet in kitchen and bathrooms should be kept clean or (preferably) replaced with a more water-resistant flooring material like tile, vinyl or linoleum. Cabinetry and counter or vanity tops should be well secured, upper cabinets should be secured with appropriate cabinet or pan head screws, and minor damage to kitchen or bathroom components should be addressed promptly to prevent further damage – especially from water.

ATTIC, INSULATION & VENTILATION: The underside of the roof structure (rafters or trusses, planks or sheathing, etc) in unfinished attic spaces should be periodically monitored for signs of possible leaking, excessive condensation buildup, microbial growth or other damage, and insulation should also be monitored. Attics in this climate zone (the Northeast) ideally contain insulation levels equivalent to R-30 to R-38 or higher, and unfinished attic access doors, hatches or panels should be sufficiently sized, well sealed and insulated. All roof framing members should be intact and well fastened, and horizontal collar ties should exist along the upper third of rafters for gable (triangular shaped) roofs in order to stabilize the roof structure – especially against wind uplift forces. Monitoring for pest activity (especially rodents) is also advised, as attics are a common nesting area for unwanted invaders. Kitchens should contain mechanical ventilation, such as an above-range microwave or range hood, to filter cooking residue and expel warm, moisture-laden air, and bathrooms should contain an exhaust fan that terminates outdoors and/or openable window to expel moisture and noxious odors to the exterior. Dryer vents should be composed of metal (preferably smooth rigid metal) and should be routed to an unscreened baffled or louvered exterior exhaust hood (although indoor lint trap canisters may be sufficient for electric dryers). Lastly, attic bypasses should be well sealed – observing required clearances around lights or heat rated vents – to prevent unwanted air leakage and ensure optimal energy efficiency.

STRUCTURE: Any structural issues that may arise in the future should be addressed immediately by a qualified professional, and any planned alterations to the home’s structure should first be reviewed and approved by a qualified structural engineer or architect. While some degree of settlement and moisture intrusion is common (especially in below-grade space), measures should be taken to ensure that the structure is continually sound and that moisture levels are not excessive. Elevated moisture/humidity levels can lead to efflorescence, microbial growth (like mold) and eventual wood deterioration, and dehumidifiers should generally be used in this climate zone (especially in basements) to help control humidity levels. Ensuring that rim (band) joist cavities are well sealed and insulated will also help improve energy efficiency, and the paper facing (vapor barrier) of insulation batts should always face the conditioned portion of the home… “paper faces people.” Cracks in basement slabs (floors) are generally not a cause for alarm, but any open cracks should be sealed and periodically monitored, and thin cracks from settlement or shrinkage in structural masonry walls should be well sealed to prevent unwanted moisture intrusion.

PLUMBING: Visible supply and waste pipes, as well as valves, should be periodically monitored for signs of leaking or excessive corrosion/encrustation buildup. Some degree of corrosion is typical of metal piping and valves, and plastic piping that will not corrode offers several advantages over metal piping (like copper and cast iron), while modern ball valves are generally more reliable and user-friendly than older style gate valves. Faucet aerators should be present and periodically cleaned, and faucets, valve handles, sinks and other fixtures should be well secured. Water heating equipment should be equipped with an expansion tank on the cold-side inlet (especially with public water supplies) to prevent possible damage to plumbing as water heats and expands, and expansion tanks should be properly secured. Gas water heaters should be elevated at least 3 inches, and their vent connector (flue) should slope steadily upward at a minimum rate of 1/4-inch per linear foot and be well sealed at its entrance into any chimney. Although often missing, dielectric unions should exist at water heater connections to prevent corrosion from an ion exchange between dissimilar metals, and at least 18 inches of rigid supply piping (typically copper) should exist directly above water heaters prior to attaching to plastic, like PEX tubing or CPVC. Older style S and drum traps are very common beneath sinks, but they can siphon out the water seal necessary to prevent sewer gases from re-entering the interior and are ideally replaced with modern P traps – especially if the water seal is frequently siphoned out. Likewise, flexible accordion style drain lines are often used for their ease of installation, but rigid plastic drain piping (typically PVC) is preferred.

ELECTRICAL: All electrical work should be completed by a qualified electrician, as electricity poses a safety risk (including even death in some cases) to untrained individuals. Ensure that smoke and carbon monoxide (CO) detectors are always located on each floor, in each bedroom, near all sources of combustion, and periodically tested for safety. It is also recommended that any GFCI receptacles be tested monthly with their onboard test and reset buttons, and GFCI protection ideally exists in bathrooms, kitchens, garages, outdoors, in basements and crawlspaces, and within 6 feet of any sink or water source. All junction boxes, receptacle outlets and switches should be covered, and faceplates should be intact and free of cracks or other damage. Older two-prong outlets (while typically “grandfathered in” with old homes) are ideally upgraded to modern three-prong grounded outlets for safety, and all outlets should be properly wired with correct voltage and firmly secured in walls, floors or ceilings. Generally speaking, branch circuit wires in electrical panels should each be secured under their own lug (screw) and not “double tapped,” and all wires should be appropriately sized or larger than required for their corresponding breakers or fuses. While not inherently defective, any older fuses are ideally upgraded to modern circuit breakers that are more user-friendly, and corroded electrical equipment that may be prone to increased resistance should be repaired or replaced, depending on the severity of buildup. Outdoor wiring should be adequately protected (typically in conduit and/or by being buried) and rated for outdoor use, and all wiring should be well secured – including within 12 inches of electrical panels. Panel legends should also be fully labeled, breakers should be designed for the panel and the same brand, and all panel cover screws should be present. Electrical panels should be readily accessible and unobstructed, and clearances of at least 36 inches in front of panels and 30 inches across their front should exist. Any incandescent bulbs that may exist would ideally be replaced with modern, more efficient LED bulbs; and any bulbs listed as not working that do not work after being replaced should be evaluated further by a qualified electrician.

HVAC: Generally speaking, heating and cooling systems should be checked, cleaned and serviced (“tuned”) every year by a qualified HVAC technician or plumber, depending on the type of system. Filters serving forced air systems should also be properly cleaned or changed on a frequent basis to promote proper airflow, optimal system performance and good indoor air quality, and dark streaks from thermal bridging (“ghosting”) may appear along walls or ceilings when dirty air particles combine with vapor and settle along cool surfaces. Despite its name, duct tape is not intended for use with ductwork, and any duct tape that may exist at duct joints would best be replaced with foil tape, mastic or another suitable sealant. If present, A/C suction lines should be thoroughly insulated with the insulation maintained in a good state of repair, and at least 12 inches of clear space should exist around outdoor condensing units with a minimum clearance of at least 3 ft directly above. Budgeting to replace A/C systems equipped with older R-22 refrigerant (Freon) is strongly recommended, as R-22 is now prohibited, and such systems sometimes require full replacement when problems arise. Heating systems requiring combustion air should exist in spaces with ample air volume or louvered openings, and any intake or exhaust vents should be screened at the exterior. Intakes for high-efficiency systems should also be run to the exterior, rather than open to basements or other interior spaces, as this can cause a buildup of negative air pressure indoors. While not required, older mechanical thermostats are best upgraded to programmable thermostats – preferably modern “SMART” models that can be controlled remotely and track data related to usage habits – to noticeably reduce energy consumption and save cost.

A FINAL WORD: While this guide covers a great deal of information and is intended to help homeowners gain knowledge and formulate a plan that is suitable to their own homes, every house is unique and will occasionally require the skill and expertise of qualified and experienced contractors. Knowing when to “DIY” (do-it-yourself) a project versus when to call in a pro is an important distinction, and no task should be tackled without confidence, careful planning and a focus on safety.
