There are many things that could eventually go wrong with your HVAC system, ultimately causing it to become more expensive to operate. Here are two essential AC maintenance jobs. One is a great DIY project, but the other should be professionally handled.
The compressor is a large energy-consuming component within the air conditioning unit. To put it as simply as possible, it compresses air, makes it cold, and helps to circulate it into your duct system. This is a very technical and complicated component, so you don't want to mess with it your yourself. It is always best to call in a professional if you suspect there is something wrong with your compressor. The compressor makes a loud humming sound. If you turn on your AC and don't hear this sound, you might have a compressor problem. Professionals will need to take apart your AC unit to test the compressor. A licensed HVAC technician can find and fix compressor problems very quickly and easily.
Cleaning the Condenser Fins and Coils
If it just feels like your airflow is a little weaker than normal, it could be due to the fact that the AC condensing coils are dirty. Many people will go years without ever cleaning or servicing the coil components of the air conditioner. In fact, you might not even know what or where the coils are. They are very easy to spot because they are along the outside wall of the AC cabinet. The lined metal sheets that you see are the condenser coil fins. The spaces in between the fins can catch dirt and debris, preventing the condenser unit from cooling off as efficiently. If your unit runs at a higher temperature than normal, it is consuming extra electricity.
To effectively clean your condenser coils, you need to invest in a special coil cleaning product. Condenser coil cleaner is a foam solution that you spray directly onto the fins so it can break down the dirt. As the liquid foams up, it will separate most of the dirt from the metal, enabling you to simply wash it out with water.
There might be some dirt that won't wash away with just water, but it is very hard to clean this off because of the protective metal cage around most air conditioning units. If you remove the protective cage, you can then clean the coils more thoroughly. But most people just use the cleaning liquid and a hose without worrying about removing the protective cage.
