Why Is There Ice In My AC System?

It kind of makes sense: ice appearing in your air conditioning system. The system is supposed to make your home cold, after all. Why should we worry about a little ice or frost on the components? In point of fact, however, ice in the system is a sign of problems that require a professional technician to resolve. When it comes to AC repairs, San Antonio residents can’t take chances, and an icy system means you should contact a reliable service to deal with it before one of our patented Texas heat waves hits. “Why is there ice in my AC system?” you ask. The answers illuminate why it’s such a problem.

Air conditioning systems depend on refrigerant gas to cool the air. The refrigerant moves through a theoretically closed system in a specified amount; the key stage in the process occurs when it enters a series of evaporator coils. The act of transitioning from a liquid to a gaseous state within the coils cools the surrounding air, which is then blown into your home with a fan.

When fissures develop in the system, refrigerant leaks out, reducing its ability to cool the air. Something similar can happen when dust coats the evaporator coils, interfering with the exchange between the temperatures outside the coil and the cooling of the refrigerant inside the coil. Either way, the result is the same: ice develops on the coils. That’s a problem for two reasons. First, the ice interferes with the cooling process, forcing the air conditioner to work harder to do its job and raising your energy bills accordingly. Secondly, when the ice melts, it can cause other problems within the system, such as overflowing the condensate pan of even shorting out electrical components.

Cleaning the ice off won’t fix the problem. Instead, you need a technician to track down the source of the leak, seal it and recharge the refrigerant to its proper levels. (If dust and dirt are the cause, it will need to be cleaned off as part of a regular maintenance session.)
