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.

Keeping Cool as the Temperature Rises

Mother Nature has decided to turn that heat dial up this weekend, leaving many people with nothing to do but crank up the air conditioning. Sure, a little A/C is a great way to provide fast relief, but keeping it blowing all summer long can do a number on your energy bill and your home. So this week I thought I’d put together a few simple tips to help you keep cool, but first, here is a story that might make you rethink your current set up.

A few years ago, I was called to a house in Bristol for a leak repair. When I got to the home, I found that the entire ceiling had fallen onto the dining room table. We hadn’t had rain for weeks, so I was confused how the leak occurred. It turns out that the home had no insulation or ventilation, and to combat the stifling heat seeping into the house from the attic, the homeowner had two window air conditioning units set on full blast all day. The cold air from the units and the hot air from the attic created so much moisture and mold that it completely deteriorated the plaster, causing the ceiling to fall in.

Having little or no insulation and ventilation in the attic will heat up your home like you wouldn’t believe. Most people think insulation and ventilation are only important in the winter, but they work as regulators, controlling air in both the warmer and colder months. Did you know that an attic can easily get up to 150 degrees on a hot summer day? Stand on a chair and put your hand as close to the ceiling as possible. Feel that heat? It’s a telltale sign that your house doesn’t have proper air flow, which, in addition to making you uncomfortable this summer, can also become a breeding ground for mold.

So what should you do? Start by investing in a hygrometer which measures water vapor in the air. A comfortable humidity reading is 30-60%, but 45-55% is an ideal level to maintain. If you’re seeing higher than 60% humidity in any area of your home, you’re going to be susceptible to mildew and bacteria growth.

Remember, attic ventilation allows your home to “breathe” so you want to balance your intake and exhaust to ensure that what is coming in is going out equally. The best ventilation system will include soffit vents which are installed underneath the overhang of the roof to take in the air and ridge vents which are installed at the top of the roof for the hot air to escape. For this method to work efficiently, all louvered vents must be sealed off and you have to ensure that your insulation isn’t blocking the airflow. Believe it or not, most roof manufacturers will void the warranty if a proper ventilation system is not installed. Luckily, new roofing technology enables contractors to add intake ventilation directly into the roof as opposed to using soffit vents so if you’re in the market for a new roof, be sure to ask for that option.

It’s important to note that homes have different characteristics and what works well for one may not work well for another. With the right balance of air, homeowners can optimize their home’s health but it’s always a good idea to get advice from a professional before taking on a big remodeling project. Stay cool friends, and have a Happy 4th of July!

Give Your A/C a Routine Check Before It Gets Beat by the Heat

Now is about the time when your central A/C or window units start to get some heavy play time. But with the first day of summer barely behind us, there are a lot of hot days left for those appliances to continue to perform at their best. A quick maintenance check now will give you peace of mind and ensure that your cooling units won’t kick the bucket during the most critical part of the summer. Plus a regular check-up will likely extend the life of the appliance too. Here are some of the things that you can do.

1. Pick a cooler day, such as tomorrow, to work on your A/C as you’ll need to shut off the power. This means both flipping the switch on the button and either unplugging it from the wall or locating the exterior shut off box on a central A/C unit. Remember, these are run on electricity so it’s always better to be safe than sorry. If you have a breaker box, you can cut the power there too.

2. For those of you with an exterior compressor, it’s time to remove the fan. First, unscrew the fan cage with a screwdriver and then take the fan right out of the unit. You’ll be shocked to see how many leaves, pollen, and debris can accumulate here. Clean the interior of the unit out with a regular or wet/dry vacuum and wipe down the fan blades too. Any dust, dirt or pollen will slow your A/C down and since there has been so much this year, it’s worth doing a thorough job.

3. Next, use a garden hose to clean the fins from the inside out. I know I spoke about the wonders of a pressure washer last week, but A/C unit fins are delicate and a pressure washer will break them. For this job, stick to the garden hose with a light flow of water. After you clean the inside, you can repeat on the outside. If the exterior is really dirty, you can apply a non-toxic cleaning solution, but just be careful not to damage the fins by scrubbing.

4. Like I said, those fins are easy to break and you may notice that the metal is bent in some places. This can cause air flow reduction and less power in and out of your machine. Using a butter knife, straighten any misaligned fins, taking caution not to pierce the tubing underneath.

5. Now you can put the unit back together. I would clear all debris from around the base of the unit as anything that is constricting the airflow will make the unit less efficient. This is a good time to take a level to it as well. If the unit is out of alignment, this can cause improper function. Remember, the ground often shifts so checking it periodically is a good idea.

6. Finally, it’s time to move inside and clean the vents and filters. Most HVAC specialists will recommend changing the filters at least twice a year and for window units, I recommend cleaning them at least once a month. Not only will your air flow be more efficient, you’ll also reduce the amount of dirty air blowing through the house. When replacing filters, make sure to match the airflow rating from your previous filter to ensure that it will work properly.

Now it’s time to breathe easy and turn your units back on. Remember, there are some jobs that should only be tackled by a professional, so if you come across a leak, major rusting, or something else that doesn’t seem quite right, do yourself a favor and get in touch with an HVAC expert. An early catch might just save you from suffering through a stifling, uncomfortable summer and an expensive bill.
