There aren't many things more frustrating than an air conditioning that refuses to run. A hot, muggy home can make your space incredibly uncomfortable, which is why I have always focused on maintaining my air conditioning system. Unfortunately, I still run into problems from time to time and I am sure that all of you do, which is one of the reasons I decided to build this website. Check out these posts for more information about keeping your system working beautifully, even if you aren't naturally good at fixing things. You never know, making the right changes could dramatically improve your summertime experience.
An AC system is only as good as its coils. In fact, an air-conditioner unit has two sets of coils. A set of evaporator coils inside your house vaporizes refrigerant to absorb heat from the air in your home. A set of condenser coils on the outside of your home expels heat from the refrigerant so that it can cycle back to the evaporator. If anything is not working quite right with your coils, you will pay too much to cool your home.
Buy the Largest Coils You Can Afford
The first key to keeping your cooling costs down is to buy large coils. The larger the coils that are included with your AC unit, the more efficiently they can do their job. Thus, if you are looking to replace your old unit or are installing one in your new house, you need to work with your HVAC technician to buy the largest coils you can afford.
If your evaporator coils don't get enough airflow, they can freeze the water vapor in the air in your home, and as more and more ice builds up on your coils, they can choke off airflow altogether. If your coils are pumping hot air or no air into your home, you should check your coils. If you find that they are iced over, then you should turn off your thermostat, let the ice melt, and then call your HVAC technician to find out what caused your coils to freeze over in the first place.
Because your condenser sits outside, they are susceptible to get clogged with all kinds of yard debris. As more and more debris builds up on your coils, they cut off airflow. Dirty coils can reduce your system efficiency by up to 37%. To clean your coils, you need to spray them with a coil cleaner, wait a few minutes for the solvents to break down the grime, then scrub your coils clean with a stiff-bristle brush.
Keeping your coils running properly is a key component of AC maintenance. Luckily, you don't have to be a trained HVAC technician in order to take care of many problems that have to do with your coils. On the other hand, if you have a fan blade that won't start up, you need to call a technician right away to take care of the problem. The bottom line is that you need to take proper care of your coils to make sure you keep your cooling costs as low as possible.
