It's terrible to be in a hot house in the summer, so an air conditioner can be one of the most important appliances in your home. However, as you run your air conditioner, the coils may start to freeze and stop working. This can be a puzzling predicament, but use the tips below to get to the bottom of the problem.
Check the Air Filter and Ducts
The filter can cause a lot of problems for you if you don't check it regularly. Not only does a dirty air filter cause more wear and tear on your air conditioner, which can cause it to prematurely fail, a clogged filter can very well be the reason that your air conditioner is freezing up. When the air cannot get through properly, the coils may freeze, and that will cause a problem.
You should be checking your air filter every few weeks, and replacing it as needed. If you notice it is dirty, clean it with a soft brush and put it back into the appliance. It should start working again.
It is also important that you make sure that the air ducts are clear. Clogged ducts can cause low air flow that can lead to freezing.
Clean the Coils
Many people with air conditioners don't bother to clean the coils as long as the machine is functioning properly. This can lead to buildup of dirt, dust and other debris, which can make the coils work less efficiently and freeze up. Make sure that you're cleaning the coils every so often to make sure that this does not happen.
Check the Refrigerant
Refrigerant is important, because after all, it cools the air. Low refrigerant levels cause the evaporator to have a problem, because the pressure in the air conditioner drops, and that can cause a freeze-up. If your refrigerant levels are low, you may have a leak that needs to be replaced by an air conditioner repair professional.
Check the Fan
If you have an outside unit that is freezing up, in some cases that's because the fan has been obstructed in some way. Leaves and other debris can easily get in between fan blades and cause it to stop functioning properly. Make sure that the fan is not obstructed and is working properly, so that you can get your air conditioner working again.
These tips should help you figure out why your air conditioner is freezing. If you use the tips above and find that your air conditioner still doesn't function properly, get in touch with a local HVAC contractor who can get your system working again.
