Keep Your Home Cooler with These Summer A/C Tips

As temperatures and humidity rise, many homeowners turn up the air conditioning to stay comfortable. However, overworking your A/C system without proper maintenance can lead to reduced efficiency, an increased likelihood of mold, and potential water damage. Here are several ways to stay cool while keeping your house’s health in check.

1. Replace or clean your air filter regularly.

A clogged air filter can reduce your A/C’s efficiency by up to 50%. Check your filter monthly and replace or clean it as needed. A clean filter improves airflow, helps the unit cool more effectively, and reduces the amount of dust, pollen, and mold in the air. When selecting a filter, consider its MERV (Minimum Efficiency Reporting Value) rating. Residential units typically use filters with a MERV rating between 1 and 12. Higher ratings trap smaller particles and can improve indoor air quality.

2. Seal gaps around window units.

Window air conditioners can allow warm, humid air into the home if not properly installed. Use foam insulation or foil tape to seal gaps around the unit. This reduces energy loss and keeps your space cooler. Materials are inexpensive and available at most hardware and home improvement stores.

3. Use a programmable timer or smart plug.

Air conditioners use a significant amount of energy. Avoid running your unit at full power when you’re not home. A programmable timer or smart plug can adjust the temperature while you’re away and return it to a comfortable level before you arrive. This helps reduce wear on the system and can lower energy bills.

4. Check attic insulation and ventilation.

Poor attic insulation can make it harder to keep your home cool, especially on hot days. If your ceiling feels warm to the touch, it may indicate that there is insufficient insulation. Improving insulation and ventilation helps maintain indoor temperatures and reduces the strain on your A/C system. This also benefits your home during the winter months.

5. Inspect your system for leaks.

Water leaks from central A/C units often result from a cracked drain pan, clogged filter, or a blocked condensate line. These issues can lead to water damage in ceilings or walls. If you notice any signs of leaking, turn off the system and inspect these areas promptly. Addressing small issues early can prevent costly repairs later.

Staying cool doesn’t have to come at the cost of high energy bills or home damage. With a few simple checks and low-cost upgrades, you can improve your air conditioner’s performance and keep your home comfortable all summer long. Regular maintenance now can also extend the life of your system and help prevent unexpected breakdowns when the heat is at its worst.

A Roof and Gutter Inspection Checklist for Spring

After a long New England winter, your roof and gutters deserve a little TLC. Spring is the perfect time to inspect for any damage left behind by winter and prep your home for the warmer season ahead. Here’s a simple 10-step checklist to help you spring into action because a quick, proactive check now can save you serious money and headaches down the road. 

1. Safety First. Start smart. Use a sturdy ladder on flat ground, wear shoes with good traction, and don’t go it alone. If your roof is steep or high, consider a safety harness or call in a pro.

2. Ground-Level Walkaround. Before climbing anything, take a walk around your home. Look up and scan for missing or damaged shingles, sagging rooflines, or any debris buildup from winter storms. A pair of binoculars is a handy tool here.

3. Inspect the Roof Surface. If it’s safe, climb up for a closer look. Winter’s freeze-thaw cycles can loosen shingles, damage flashing, and open up trouble spots. Focus on high-risk areas like valleys, chimneys, and skylights.

4. Flashing & Seal Check. Snow and ice can crack flashing and wear down seals around vents and roof joints. Look for gaps or rust, and re-seal any areas that no longer look watertight.

5. Clean Out the Gutters. Winter storms can clog your gutters with leaves, pine needles, and shingle grit. Clear out all debris and make sure water flows freely through the downspouts—otherwise, you’re risking water damage and foundation issues.

6. Confirm Gutter Slope. Gutters should slope slightly toward the downspouts. If water pools or overflows, grab a level and check. Adjust the hangers as needed to restore proper drainage.

7. Check Fascia & Soffits. Cold, wet weather is hard on wood. Look for signs of rot, peeling paint, or pest activity on the fascia boards and soffits—these areas often show the first signs of hidden water damage.

8. Peek Into the Attic. Head inside and inspect the underside of your roof. Water stains, mold, or musty smells could mean you’ve got a leak. Also check that your attic vents are clear to allow air to circulate and moisture to escape.

9. Take Photos. Snap pictures of anything that looks questionable. These will come in handy if you need to call a contractor—or if an insurance claim is necessary.

10. Schedule a Pro Inspection. Even if everything looks good, a professional inspection once a year is a smart move. Pros know where to look for hidden issues and can help extend the life of your roof with early fixes.

Spring is the season for fresh starts and smart maintenance. Your roof worked hard all winter. Give it the attention it deserves this spring so it can keep doing its job all year long. A little maintenance now means fewer surprises later.

Mold in the Home: Why Spring is Prime Time for Growth in Connecticut

When spring rolls into Connecticut, we welcome warmer temps, blooming flowers—and unfortunately, the perfect storm for mold. With all that spring rain and lingering moisture, mold growth becomes a common (and sneaky) issue for homeowners this time of year.

Mold thrives in damp, dark spaces, and once it finds a cozy spot in your home, it doesn’t need an invitation to stick around. Whether it’s behind walls, under flooring, or up in the attic, mold can quietly spread while you’re none the wiser—and it’s not just your home at risk. Mold spores in the air can also wreak havoc on your health.

Most people associate mold with the usual suspects: the shower tiles, the bathroom grout, or that old sponge you really should toss. But mold problems often lurk in much less visible places. If you’ve ever had a roof leak, a damp basement, or a poorly ventilated attic, odds are you’ve had mold—even if you never saw it.

In fact, at least half the homes I visit for remodeling projects have mold problems hiding beneath the surface. It’s not always dramatic black splotches on walls; sometimes, it’s the faint discoloration on a ceiling or that musty smell in a room that never quite dries out.

So, what can you do to stop mold before it becomes a serious (and costly) problem? Start by keeping moisture at bay—especially during the wet spring season. Here are my top prevention tips:

• Keep gutters and downspouts clear so water drains away from your foundation.

• Grade your yard properly. The ground should slope away from your home, not toward it.

• Fix roof leaks immediately, and have your contractor check for any mold during repairs.

• Watch your ceilings for discoloration or bubbling paint—these are red flags.

• Install quality ventilation in bathrooms, and make sure fans vent outside, not into the attic.

• Don’t let carpets stay damp. Mold can begin forming within 48 hours of water exposure.

• Place trays under large appliances like washing machines and refrigerators to catch leaks.

• Use a dehumidifier in basements or any area prone to excess humidity.

And here’s the kicker—if you’ve already tried cleaning or painting over mold and it keeps coming back, that’s a big red flag. Surface fixes won’t solve a deeper issue. If mold returns, it’s time to bring in the pros before it spreads further or impacts your indoor air quality.

Spring is beautiful in Connecticut—but it’s also wet. Don’t let mold sneak in with the season. A little prevention now can save you a big headache (and an even bigger repair bill) later.
