Air ConditioningThere’s Ice on My AC. Is This a Problem?

Yes, absolutely. You may think that, because an air conditioner serves to cool your home down, ice forming on its components is merely a sign that it is operating optimally, if not a bit too zealously. In truth, though, ice forming on an air conditioning system is never a good sign. There are a few different reasons as to why ice may develop, and they may vary in terms of severity. One thing is true across the boards, though: it’s always indicative of trouble. In the following post you’ll learn a bit about why ice may form on your AC. If it does, be sure to schedule air conditioning repairs in Everett, WA immediately.

Clogged Air Filter

We are always reminding people of how important it is that they change their air filters regularly, as suggested by the manufacturer. This is a prime example as to why doing so is so important. If your air filter is clogged up, it can limit airflow over the evaporator coil in your AC system. This can hinder the heat transfer process, and your evaporator coils may freeze over as a result.  Fortunately, you need only clean or change your filters in order to resolve the problem if this is the case.

Dirty Coil

Over time, dirt, dust and grime can accumulate on your evaporator coil, which is just one more reason as to why routine AC maintenance is so vital. During a maintenance visit, our technicians will clean your coil, along with completing countless others tasks and checks. If your evaporator coil is dirty, the same issue with impeded heat transfer can result.

Refrigerant Leaks

This is probably the most serious reason why an AC may ice over. Your system is designed to work with a certain level of refrigerant. If you have a leak, and your refrigerant level is low, the coil and the refrigerant lines themselves may drop in temperature, resulting in ice accumulation. If this is the case, you need to have the leaks pinpointed and repaired, and the system’s refrigerant recharged.
