Does your air conditioning keep freezing up? We know how inconvenient you can be—especially when you need your cooling system to be up and running to help fend off the Phoenix heat. Air conditioners are designed to lower temperatures, but did you know that an air conditioner can actually get too cold? It’s true! And this is what you’re experiencing when your air conditioner has become frozen.
Unfortunately, a frozen air conditioner won’t resolve itself, but it’s a problem that should be addressed immediately! If left unaddressed, you could find yourself needing an air conditioner replacement sooner than you expected.
If you have a frozen air conditioner that needs to be fixed, the AC contractors at AC by J can help. Give us a call at 602-266-3678 to schedule an appointment for Phoenix air conditioner repair—or book online!
Reasons Your AC System Is Freezing Up
Simply put, your air conditioner keeps freezing up because something is either causing the refrigerant in your system to expand more than it is designed to, or something is preventing the air in your house from transferring its heat into your air conditioning system. Whatever the case may be, our technicians can help you diagnose the problem and provide a quick and efficient resolution to get your system operating at peak efficiency.
The evaporator coil is the part of a central air conditioning unit that actually freezes. This part of the air conditioner transfers (evaporates) heat from the inside to the outside of your home.
The two main reasons why the evaporator coil might freeze are:
1. Airflow restriction. If your air conditioner is not properly blowing air over the evaporator coil, then the heat exchange cannot take place and your air conditioner can freeze up.
2. Insufficient refrigerant. If your air conditioner is low on refrigerant, then your air conditioner can freeze up due to lower pressure inside the system itself. As your air conditioner’s evaporator coil drops below freezing, the moisture in the air will freeze as it comes into contact with your coil.
Either way, the final effect is that the air conditioner’s evaporator coil doesn’t operate properly to effectively to transfer heat, and in essence ‘over-cools’ itself. The net effect of this over-cooling is ice forms on the coil as it goes below the freezing point. In essence, your air conditioning keeps freezing and is transformed into an old-school refrigerator.
How to Prevent Your AC From Freezing
The two most important preventative steps to prevent your air conditioner from freezing up are to, first, regularly change your air filter. This is one of the most common causes for restricted air flow through your air conditioner. If your AC filter gets clogged, then the restricted air flow can cause your air conditioner to freeze up. Second, clean your evaporator coil. A dirty evaporator coil can cause a significant reduction of airflow across it causing your air conditioner to freeze up. The best solution for this is to have an air conditioner tune-up performed twice a year by a professional, like the team at AC by J. This will help keep everything functioning optimally all season long.
