Keep Your Home Cooler with These Tips

When the weather gets too hot to handle, many homeowners simply crank up their air conditioning to stay comfortable. But what people may not realize is that the combination of cold air and high humidity could lead to leaks. So what can you do to stay cool without putting your home at risk? Here are some tips: 

Keep the filter clean. 

A dirty filter can cut your air conditioner’s efficiency in half, so be sure to replace or wash it at least once a month during the summer. Not only will a clean filter enable more cold air to come through the unit, but it will also decrease the amount of pollen, dander, and even mold that you could be breathing in. Many people don’t know that air conditioning units are rated by their MERV, which stands for minimum efficiency reporting value or, more simply, the effectiveness of the filter. MERV ratings are between one and 20, with most home air conditioning units rating between one and 12. If you’re in the market for a new filter, choose one at the top of the scale as it can trap smaller particles and protect your home from mold spores, dust mites, and other nasty contaminants. 

Make sure your windows are leak-free. 

Window A/C units are tough to fit and often result in large gaps where the hot air outside can come in. Make sure all the space around the air conditioner is sealed up tight with foam for bigger gaps or simple foil tape for smaller areas. The materials you’ll need can all be found at the local hardware store and you’ll be shocked by the difference in air temperature by just plugging up those holes. 

Run the unit on a timer.

There is no point running your A/C on high when you’re at work or away for the weekend. A digital timer will lower the unit’s output when you’re not at home, and then bring the house to a comfortable level by the time you walk in the door. By programming a timer to your preferences, you can lengthen the life of the unit and lower your energy bills without noticing a difference in the level of comfort. If you don’t rely on Alexa, you can buy a smart plug for your outlet to control your A/C from your phone.

Up your insulation.

If your attic isn’t properly insulated, it’s going to be a sauna up there. You don’t even need to go up to check - you can tell simply by touching your ceiling. If it feels hot, then imagine how hard it is for a window unit or even central A/C to compete. A well-insulated and ventilated attic will ensure that hot air can escape while keeping cool air circulating in the living areas of the home. Plus, proper insulation comes in mighty handy during the cold months of the year. 

Watch for leaks. 

Central air conditioning units are notorious for leaks for three reasons: a cracked or broken drain pan, a clogged air filter, or a plugged-up condensate line. If water can’t drain properly, it will end up in your ceiling or walls which can cause serious and expensive damage. If you see even the smallest leak, shut down the unit and inspect these three areas. A simple fix might save you thousands in damage if you act quickly.

Summer Humidity Can Cause Problems in the Home

Even with all this rain, it won’t be long before summer weather is in full swing.

With New England's heat also comes humidity, a potential problem that every homeowner needs to keep in check. While we can’t control the weather outside, moisture inside can be a major problem, contributing to mold, mildew, and overall dampness, especially in the attic and basement. 

Many homeowners combat humidity by using air conditioners in their houses, and while they can reduce the moisture in the air to some degree, this is by no means their primary function. An air conditioner works by sucking the air from your home, cooling it, and blowing it back into the house. That process does reduce the humidity slightly, but pairing your air conditioner with a dehumidifier is a much smarter option.

A dehumidifier works by pulling the moisture out of the air and storing the excess water in a holding tank. Many people keep dehumidifiers in their basements all year to control the dampness that can often be felt in these underground areas. This is a great idea because controlling the humidity in the part of your home that holds the most water will likely help regulate the rest of the house.  

One way to know if your house holds a lot of moisture is to purchase a simple five-dollar humidity gauge from the local hardware store. Ideally, you want the humidity to be under 50 percent. If it’s higher, you might want to consider using a dehumidifier in the main part of your home, especially on hot summer days and in areas where you spend the most time. 

In addition to cooling the air and decreasing moisture, running a dehumidifier during the hottest parts of the hottest days can also prevent mold and mildew growth, eliminate musty odors in the home, and prevent old pipes from sweating. Plus, you can use the water collected in the tank to give your plants a good drink. 

If you’re thinking that a dehumidifier might be a good solution for you, they come in different sizes and can be used for residential or commercial purposes. Generally, a unit will come in 25, 30, and 40-pint models, and on average a 25-pint unit will be sufficient to operate in a 1,000-square-foot area.

Dehumidifiers generally run on about half the energy of an air conditioning unit, so as long as you don’t run them all day, using one shouldn’t affect your energy bill. Just keep windows and doors closed when you run your unit, and only switch the power on during the most humid time of the day, or when the air is above 50 percent humidity. Also, be aware that dehumidifiers by nature are drying, so try not to run them while you’re occupying the room over a long period of time, like when you’re sleeping at night.

Finally, if you have a dehumidifier, be sure to keep the filter clean. Dust, dirt, and debris can build up, preventing air from flowing freely and potentially circulating mold spores throughout the home. A simple wipe-down with a damp cloth and spray bottle filled with a cleaning solution will do the trick to keep you breathing freely and ensure a longer life for your appliance.

Mold in the Home: A Common Problem in Spring 4-4-24

Mold is an issue that most homeowners have to deal with at one time or another. It’s the damaging by-product of excess moisture that can wreak havoc on your home, and more importantly, your health. With spring in full swing, now is a good time to inspect your house for mold and get rid of it before it does any kind of serious damage. 

You might be familiar with mold or mildew from your shower or bathtub. Since the shower is often wet and the tiles are waterproof, water can sometimes seep into the grout. If the grout is old and can’t handle its repelling duties properly, it becomes a breeding ground for mildew which can generally be cleaned with a good scrub. But what happens when mold starts to grow in the places you can’t clean as easily – places like your ceiling, inside your walls, or in the attic? You’re probably saying, “Not in my house”. Well, guess again.

At least half the homes I visit for remodeling projects have a major mold problem and the owners don’t even know it. How? Because mold generally grows in places that you can’t see – like inside the walls and in the attic. What most people don’t realize is that mold reproduces by releasing spores that you’re breathing in day after day.

How common is this? If you’ve ever had a leak, you’ve most likely had a mold problem. So what can you do about it? You can prevent mold by ensuring your home stays dry. Here are my top tips:

1. Keep your gutters and downspouts clean and clear so water can drain away from the foundation of your house. 

2. Make sure the ground around your house doesn’t slope inward towards the foundation where water can idle.

3. Don’t let a leaky roof go unfixed.  Get it patched up immediately and ask your contractor to inspect for any mold growth.

4. Inside the house, beware of any discoloration on the ceiling.

5. Ensure high moisture areas like bathrooms are well-ventilated with good ceiling fans that don’t vent into the attic.

6. If a leak happens in a carpeted area, don’t just leave it to dry. A damp area can attract mold in less than 48 hours.

7. Ensure large appliances such as refrigerators and washing machines have a catchment tray in case of a malfunction.  

8. If you think your house or basement is susceptible to high moisture, consider purchasing a dehumidifier to regulate the humidity and remove any excess moisture from the air.

If you’ve had a mold problem that you’ve tried to control by scraping, cleaning, and repainting the area, don’t make the same mistake twice. If the mold keeps coming back, that means the issue runs deeper than the eye can see. It’s time to call in the pros.
