Maintain Your AC Unit for a Cool, Cool Summer

The summer heat and humidity can be a killer, and if you’re like most homeowners you simply crank up the air conditioning when the weather gets too hot to handle. Unfortunately, an overflow of cold air can put your home at risk, and I don’t just mean your energy bills. Just this past week I have had a dozen calls from homeowners in the area whose exuberance for A/C has turned into a leak, damaging internal walls and ceilings and leaving a heck of a mess to clean up. So if you’re inclined to keep those A/C units on heavy rotation, follow these tips to ensure that your home stays protected for the rest of the summer.

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 out of the unit, 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 they can trap smaller particles and protect your home from mold spores, dust mites, and other nasty contaminants.

Make sure the window is 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 leaks.

Run the unit on a timer.

There is no point in 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 your air conditioner doesn’t have a timer, you can get one for as little as $10 online or at the home improvement store in your neighborhood.

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 with all that heat. A well insulated and ventilated attic will ensure that the hot air can escape while keeping the 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.

Reduce Indoor Air Pollution and Breathe Easy With These Five Tips

When most people think about air pollution, they envision smog and exhaust that exits factories and cars, contaminating the air that we breathe outside. But did you know that the air inside your home can be shockingly more polluted than what you’re breathing outdoors? Believe it or not, lead, radon, formaldehyde, dust, cleaning chemicals, mold, mites, and pet dander are all hidden pollutants living inside your home, affecting your family’s health on a day-to-day basis. While we don’t want to think about it, it’s a common reality that I see in houses all over our area and it’s doing more damage than you probably realize.

Because people are spending more time indoors, we are seeing indoor air pollution take its toll more severely, especially in young children and elderly people who can develop asthma or breathing problems due to the hidden contaminants in their home. So what can you do to make sure your air quality is up to par? Here are five simple tips:

Get tested. Radon and lead tests can be done by a professional and are also available in at-home kits. If your home as built before the late 1970’s it’s a good idea to have it tested as lead-based paint was highly common and causes a range of health problems, especially in young children. As for radon, it just so happens to be the number two cause of lung cancer in the USA.

Watch the water. Mold loves moisture, so if your home regularly clocks humidity levels above 50%, you’ll want to start running a dehumidifier. The amount of mold and mildew build-up I see in people’s homes would shock you, yet they wonder why their kids have asthma and their elderly parents can’t breathe. Here’s an extra tip: a humidity reader costs less than $10 at the local hardware store.

Clean your vents. Proper ventilation is vital to ensuring your home can breathe properly. While most people don’t have enough attic ventilation as it is, they also forget to clean the vents that are accessible and easy to maintain. The dryer vent, air conditioning filter, and even your blow-dryer are likely chock full of dust and dander so be sure to keep them clean.

Go green. Household plants are a fantastic natural ally in keeping your air quality up to scratch. Palms, ferns, English Ivy, and Peace Lily are common indoor plants that also earn top marks for ridding the air of toxins. Just remember that you’ll need one plant for every 10 square yards of living space.

Make it a habit. Cleaning the house regularly will improve air quality simply because dust traps chemicals and allergens in it. Upgrade your vacuum cleaner for one with a high-efficiency particulate air (HEPA) filter and make sure to wash kids stuffed animals regularly with hot water as dust mites love living in fabric materials. When you start running low on a household cleaning product, swap it out for an all-natural alternative without the harsh chemicals. While you’re at it, say goodbye to those synthetic fragrances too - according to one study, a popular plug-in air freshener was found to contain 20 different volatile organic compounds (VOCs), including seven regulated as toxic under U.S. law. An essential oil diffuser will do the job without the poisonous toxins. Now breathe.
