Tempe AC Repair Service. What Makes AC Units Freeze?

Ice may form around your air conditioner if you use it frequently during the warmer months.

Some may see the AC freezing as a positive because it means your system is producing cooler air, yet you can see it is so severe a block of ice forms, preventing the flow of heated or cooled air into your home.

When the correct pressure, airflow, and temperature control are in place, the air conditioner will function optimally. Reasons your air conditioner might freeze up, necessitating Tempe AC Repair service, are discussed below.


Your AC Unit Needs Tempe AC Repair for Low Refrigerant

An air conditioner would be useless without a refrigerant, as it uses this to remove warm air inside the house and release it outside while making rooms cooler inside. However, because of a leak in the air conditioner's coils, the refrigerant level drops because of joint, valves, and fitting issues.

Cooler temperatures are needed to achieve compression and phase change from liquid to. The condensing coils' operating temperature falls below the norm, and condensation freezes. In addition, the trapped vapor needs to cool before condensing into a liquid and draining into the pan.

Call a Rescue One Air repairman if you see ice forming on the evaporator. A Tempe AC same-day repair professional will refill the refrigerant to stop the freezing. If you have regular Tempe AC service, you won't have to worry about this happening.


Your AC Unit Lacks Airflow

Most air conditioners freeze when warm air stops blowing over the coils due to restricted airflow. Clean or change filters often, as dust clogs filters and restrict airflow.

If the AC's ductwork is undersized, insufficient air will flow over the coils, causing freezing, and oversized ductwork reduces air pressure.

When the blower fan fails, it disrupts airflow and pressure, causing the evaporator coil to freeze so your AC won't circulate air. So now you need Tempe AC repair.


Inefficient Compressors Cause Ice On AC

A malfunctioning compressor will not effectively pump the refrigerant. Because of this, the coils will cool down and condense moisture. Over time, it freezes inside the air conditioner and forms ice. Inconveniently, fixing a broken compressor isn't simple. Complete unit replacement may be required in extreme cases. However, if you consult with our technicians, we will suggest the most appropriate next steps.


Your AC Drain System Fails

When an air conditioner functions correctly, it condenses water from the indoor air. Then a drain pan collects the water as it drips.

A clogged drainage system causes moisture accumulation in the coils. As a result, the evaporator coils will freeze if subjected to continuous heat absorption from the moisture.

Your Tempe heating and cooling system technician is another source of expert advice and can do this with regular Tempe AC maintenance visits.
