Dirty Air Conditioners

We are well into summer and many areas are seeing temperatures in the 90s or higher. We rely on our air conditioner to keep us cool and comfortable during times like this, but is it working as well as it could be? For many, the answer is no. The reason is simple lack of maintenance. Your air conditioner sucks outside air through the metal condenser coil while it’s running. Dust, bugs, grass, dirt and all kinds of other contaminants can get sucked in and stuck in the coil. Eventually this build up reduces the airflow through the coil, reducing the cooling capacity of your air conditioner. This means longer run times and more energy usage. It could also mean that your system won’t be able to keep up on the hottest days.

The solution is simple. Just spray the outside of the coil, working from the top down, until the debris is gone and the coil looks clean. If your coil is very dirty, the unit will require disassembly and a coil cleaning chemical to get it fully cleaned. If this is the case, you may want to hire an HVAC company to clean your unit. If you are mechanically inclined and want to take the side panels off for a full cleaning, Nu-Calgon Nu-Brite is an excellent coil cleaner. One gallon should last a long time since it must be diluted with water in a sprayer at a 1:4 ratio.

Whether you choose to clean it yourself or hire a pro, your AC will reward you with higher efficiency and less breakdowns when you keep it clean!
