Common Air Conditioner Problems

Anyone who has lived in Arizona for a summer knows that air conditioners are not a luxury, they are a necessity. Each year, the temperatures seem to jump a little higher than the last. As the weather heats up, it is important to have a unit that will be able to keep you cool in the coming months. In this week’s article, we are going to take a look at some of the most common problems in air conditioning units and how to fix them. 


Dirty Filter

A dirty filter can wreak havoc on your HVAC system, and before you know it you’re having to repair frozen coils. This is because a clogged filter will restrict airflow. Not only will that make your AC unit have to work harder to hit those lower temperatures, but will also reduce the amount of air flowing past the coil. All the condensation on the surface of the coil that usually dissipates with the air flow will soon freeze up and render it useless. According to experts, you should be changing your filter every 30 to 90 days depending on the amount of allergens in your home. 


Refrigerant Leak

Refrigerant is what removes the heat and humidity from your air. If it is low, simply add more. If there is a leak, your air conditioning unit will not be able to perform its job. Unlike a dirty filter, this problem requires professionals. A trained technician will need to inspect your lines, isolate the leak or leaks, and repair as needed. The longer you leave a leak, the harder it is on your AC and the environment, so don’t put it off!


Dirty Condenser Coils

Condenser coils work by expelling hot air outside of your home. As it is an outdoor component of your HVAC, it is susceptible to dirt and debris build up. Again, your unit must work harder to expel the hot air, costing you more in utility bills. It can even shorten the lifespan of your AC. Regular cleaning is necessary in order to keep it functioning properly. 


Leaking Ducts

Just because the ductwork in your home is tucked behind walls and above ceilings, doesn’t mean it isn’t vulnerable to disrepair over time. If they begin to leak, all the cool air from your air conditioner won’t be able to make it to its intended destination: you. Leaks should be examined and repaired by a trained professional.
