Why Your HVAC System is Freezing Up

Wintertime in El Paso, Texas, comes with relatively cool temperatures, but this doesn’t mean your air conditioner is done for the season. In fact, record winter highs in El Paso and southern New Mexico have climbed above 80 degrees Fahrenheit.

Having your HVAC system freeze up during a hot streak reduces your indoor air quality and can lead to even worse long-term issues for the entire unit. The good news is that you can take a preventative approach to help avoid a costly repair down the line.

Closed Air Registers and Dirty Air Filters Impede Air Flow

One of the biggest causes of HVAC freeze up is a lack of warm air reaching the cold coil. In most cases, this problem can be traced to a dirty air filter or air registers that have been closed off in an attempt to save money.

Not only can you easily control these factors but you can also save money on your energy bill by doing so. Believe it or not, closing vents makes your energy costs go up, not down.

Lack of Refrigerant Harms the Unit

Low refrigerant levels are bad news and can cause a lot of damage. Your HVAC system will warn you that your refrigerant levels aren’t high enough in many ways, including hissing or bubbling noises coming from the unit, the development of ice on the refrigerant line and hot air blowing from the AC.

A Faulty Thermostat is a Costly Problem

Does your thermostat never seem to work properly? If you set it to 72 degrees Fahrenheit, but it runs so long you can almost see your breath while indoors, you have a problem. If this problem isn’t fixed, your HVAC unit will be damaged by the coils freezing up.
