AC Repair: Frost On Your AC

AC Repair

Air conditioning systems are designed to keep us cool, which is serious business here. Our summers can get quite uncomfortable, with high temperatures and higher humidity being the norm. Homeowners who notice frost on their air conditioning system may not think that anything is amiss. In fact, however, the presence of frost or ice signals a significant problem, requiring professional ac repair service. “Why is there frost on my air conditioner?” you ask. Simply put, because your air conditioner is malfunctioning.

Wasted Cooling Power
Ice and frost usually appear on the evaporator coils and this is a sure sign your system needs ac repair. The point in the system where the air is actually cooled. Liquid refrigerant enters the coils under high pressure, where it evaporates into gaseous form. The process pulls heat from the air surrounding the coils, cooling it down significantly. That air can then be blown into your home via a fan. When refrigerant levels are lower than they should be or the system is otherwise malfunctioning, that process is curtailed. As a result, frost forms on the evaporator coils, representing cooling power that should be going into your house.

Higher Costs
What does that mean in practical terms? Lost cooling power wastes energy, which means your air conditioner needs to work harder in order to do its job. As a result, your monthly bills will go up, and the added strain increases the chances of a more serious breakdown in the future. Indeed, the frost actually serves as an insulator between the refrigerant and air it’s supposed to cool, compounding the trouble and further increasing the risk of needing ac repair.
