Longmont Air Conditioning

What do you know about your cooling system? Do you know how to spot problems whenever they occur? If not, call the heating and air conditioning company that knows best and how to treat your AC under challenging conditions.

Common problems with air conditioning:

  • Refrigerant levels
  • Coils

Refrigerant and the coils of a cooling system are two components that go bad over time. Low refrigerant, also known as Freon, is what cools the air. When faced with a shortage in refrigerant, your unit could face leaking.

The coils can also freeze up seizing the units itself. Running a system too much will freeze the AC and block the return. When this happens; calling in a specialist is what’s recommended because the problem will only get worse when left to “thaw” out.
