If you've been noticing ice building up on your air conditioner, it's time to call for repairs. In some cases, an icy buildup can be caused by improper refrigerant levels, or leaks in the lines. However, there are other issues that can cause the formation of ice. If you've already had the refrigerant levels topped off, and you're still facing problems with ice, your AC repair technician will need to take a closer look at your unit. Here are several other problems that could be causing the ice formation.
You've Got Clogs in the Condensate Lines
When your air conditioner develops an icy buildup, it can't function as efficiently as it should. Clogs in the condensate lines or drain pan can lead to the formation of ice. Luckily, those issues are easy to repair. If you're dealing with ice buildup, and decreased air flow, your technician will attempt to clear clogs from the condensate lines, and remove dirt and grime from the drain pan. Depending on how long it's been since your condensate lines and drain pan have been cleaned, you may also have a problem with algae or mold. If that's the case, your condensate lines and drain pan will need to be thoroughly cleaned and sanitized.
Your Coils Need a Deep Cleaning
If the coils on your air conditioner are dirty, the lack of air flow to the condenser could be causing the formation of ice. Many people wrongly believe that cleaning the coils with a garden hose will take care of the problem. Unfortunately, that's not the case. Cleaning your coils with a garden hose will remove the surface dirt, but it won't get rid of the caked on dirt that's found deep inside the coil grooves. To remove that dirt, you'll need to have your coils professionally cleaned. Not only will a professional cleaning remove all the caked on dirt, it will also ensure that damaged coils are identified and repaired before they can cause additional damage.
Your Ducts are Damaged or Outdated
If you're dealing with ice buildups that won't go away, and your air conditioner is working harder than it should, the problem could lie deep inside the ducts. Like dirty coils and clogged condensate lines, damaged or outdated ducts can interfere with proper airflow, which can lead to the formation of ice. If you haven't had your ducts inspected in a while, you need to arrange for that service as soon as possible. There may be damage that will need to be repaired before your air conditioner will function properly.
