Insufficient air flow, improper use of the thermostat, and other factors contribute towards the freezing up of the air conditioner. To unfreeze your unit you need to do a number of things. These things include:
Check the air filters
Air filters not only prevent dirt from getting into your house, they also regulate the amount of air that gets into the evaporator coils. According to AC contractors, when the air filters get clogged, not enough air can reach the evaporator coils and due to this, the unit tends to freeze up. You should inspect the filters and if dirty, clean them. In some cases, you may have to replace the air filters especially if they are in bad shape.
Inspect the evaporator coil
Other than the air filters being dirty thus causing your unit to freeze up, the evaporator coil can also be dirty. You should inspect the coil and if dirty, clean it. You should note that the coils are delicate and you can destroy them if you aren’t careful. To be on the safe side you should exercise a lot of caution when you cleaning them. If you don’t trust your skills you should ask an AC technician to help you out.
Take a look at the ductwork
Sometimes the air is restricted at the ductwork and this can be problematic. If the air filters and evaporator coil are clean, you should take a look at the ductwork. You should open all the air conditioning registers and inspect the ductwork for bends, leaks, or any disconnected areas. To do this you will have to go into the attic. It can be dangerous doing so especially if you have never done it before. If you feel that you can’t do it, you should ask a professional to help you out.
In addition to inspecting the ductwork for leaks, you should also inspect it for dirt. HVAC technicians report that a lot of dirt can prevent an effective flow of air; therefore, you should clean them. It’s easy to damage the ductwork during cleaning; therefore, you should leave the work to a professional if you have never done it before.
Conclusion
These are some of the things you should do when you have a frozen air conditioner. You should check the air filters, inspect the air filters, and your ductwork and if dirty, clean them. If damaged, replace them. To have an easy time, you should work with a reputable HVAC company.
