Question 1

Why is my AC running but not cooling my home in DFW?

Accepted Answer

The most common causes are a dirty air filter restricting airflow, low refrigerant due to a leak, a failing capacitor, a frozen evaporator coil, or an undersized system struggling in extreme Texas heat. Start by replacing the air filter and checking that all vents are open. If that does not help, call an HVAC technician.

Question 2

What are the most common HVAC problems in DFW summers?

Accepted Answer

During peak Texas summers, the most common HVAC failures are capacitor failures, refrigerant leaks, clogged condensate drain lines that trigger safety shutoffs, and dirty evaporator coils. These are all repairable without replacing the full system in most cases.
