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.

Combat Summer Humidity in the Home

After a lot of rain followed by heat and humidity, it’s no surprise if your house starts to feel a little swampy. Summer weather may be great for your garden, but it can spell trouble for your home if humidity isn’t kept in check.

While we can’t control what’s happening outside, the real concern is what that sticky air is doing inside, particularly in basements, attics, and anywhere else moisture loves to settle. That moisture can lead to mold, mildew, musty smells, and even damage to your home’s structure over time.

A lot of folks assume their air conditioner has them covered, but the truth is, while it cools the air, its dehumidifying powers are more of a side effect than a solution. Air conditioners recycle and chill indoor air, which helps a little with moisture, but if humidity is high, they’ll struggle to keep your home comfortable and dry.

That’s where a dehumidifier comes in. Unlike an AC unit, a dehumidifier’s sole job is to pull excess moisture from the air and collect it in a tank. If you’ve ever felt that damp, clammy vibe in your basement, you’re not imagining things, and a dehumidifier can make a big difference. In fact, starting in the basement is a smart move, since that’s usually the most humid part of the house.

Want to know how humid your house really is? A $5 humidity gauge from the hardware store will tell you. Ideally, your indoor humidity should be under 50%. If it’s higher, consider running a dehumidifier in the most-used parts of your home, especially on those muggy days when it feels like you’re living inside a wet sponge.

Bonus: a dehumidifier doesn’t just make the air feel more comfortable. It also helps prevent mold growth, eliminates musty odors, and keeps old pipes from sweating. And here’s a neat trick, reuse the water collected in the tank to hydrate your plants. They won’t complain.

Dehumidifiers come in different sizes, usually 25, 30, or 40-pint models. A 25-pint unit generally works well for a 1,000-square-foot space, making it a good fit for most basements or mid-sized rooms.

Worried about the energy bill? Don’t be. Dehumidifiers typically use about half the electricity of an AC unit. To save energy, only run the unit when humidity spikes (above 50%), and keep windows and doors closed while it’s on. Just don’t run it all night in the bedroom - they can dry out the air a bit too much while you sleep.

And don’t forget maintenance. Dehumidifiers can get clogged with dust and debris, which blocks airflow and could even spread mold if left unchecked. A quick wipe-down of the filter with a damp cloth and a spritz of all-purpose cleaner will keep things running smoothly.

Late Winter Tasks for Homeowners

As Connecticut homeowners brace for the final stretch of winter, it’s a good time to focus on a few important tasks before spring arrives. With the unpredictability of late winter weather, these tasks will help ensure your home is prepared for both the lingering cold and the transition into warmer months. Here are some key tasks to consider in late winter:

1. Inspect Your Roof and Gutters

Winter storms, snow, and ice can cause damage to your roof. Before the snow melts completely, it’s important to inspect your roof for any missing or damaged shingles, especially if you experienced heavy snow or ice buildup. Be sure to check your attic for any signs of leaks. It's also a good time to clear out your gutters. Ice and snow can cause gutters to clog with debris, which can lead to water damage when the snow begins to melt.

2. Check Windows and Doors for Drafts

Late winter is a good time to check your home for drafts. Cold air can slip through gaps around windows and doors, which can increase heating costs and decrease comfort. Walk around your home and feel for drafts. If you find any, consider adding weatherstripping or caulking to seal the gaps. This small effort can make a big difference in maintaining an even temperature and reducing energy use.

3. Prepare Your Heating System for the Final Stretch

In late winter, your heating system has been working hard for several months. To ensure it continues to operate efficiently, change the filters in your furnace or heating system. Dust and debris can clog filters, forcing the system to work harder. Check your heating vents and baseboards for any blockages to make sure warm air flows freely throughout your home. If you haven’t had a professional checkup yet, consider scheduling one before the coldest months are behind you.

4. Check for Ice Dams

Ice dams are a common issue in Connecticut during late winter, and they can cause significant damage to your roof and attic. They occur when snow on the roof melts, but the water refreezes at the eaves, creating a barrier that traps water on the roof. This water can seep into your home and cause leaks. If you notice ice buildup along the eaves of your roof, take action by using a roof rake to clear snow or contact a professional to safely remove the ice dams.

5. Prepare for the End of Snow Removal Season

Even though the snow might be thinning out, it’s important to stay prepared for any late-season snowstorms. Make sure your snow removal tools are in good condition. If you use a snowblower, check the fuel levels and ensure that it's ready for use. Stock up on ice melt or sand to help with slipping hazards as temperatures fluctuate.

6. Take Care of Winter Wear and Gear

With the end of winter on the horizon, it’s a good time to inspect and organize your winter gear. Clean snow shovels, salt spreaders, and other tools that you’ll be putting away until next year. Ensure that your winter clothing, like jackets, boots, and gloves, are in good condition for the final stretch of cold weather.

7. Inspect Your Pipes for Potential Freezing

While Connecticut winters are generally mild compared to other parts of the country, freezing pipes can still become a concern, especially during extreme cold snaps. Check any exposed pipes, particularly in areas like basements, attics, and garages. If you notice any cracks or weak spots, consider wrapping the pipes in insulation to protect them from freezing. If you’ve already had issues with frozen pipes, it may be a good idea to check for any damage to the plumbing that could cause leaks as the weather warms.

8. Clean Your Fireplace and Chimney

If you use a fireplace for heat or ambiance during the winter months, make sure to clean the chimney before the season is over. Creosote buildup in the chimney can be a fire hazard, so consider scheduling a professional cleaning if you haven’t done so recently. This is especially important before you begin to use the fireplace less frequently in the spring.

By focusing on these late winter tasks, homeowners can stay ahead of potential issues and ensure their home remains comfortable and efficient as the seasons transition. While spring may feel a little way off, a bit of late winter prep can make the changeover smoother when the time comes.
