Texas Licensing and Efficiency Rules
Texas is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Texas the company should carry a state license or registration. Ask for both.
Before You Hire
- Keep two feet clear around the outdoor unit, including snow.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.
- Book maintenance twice a year, once before summer and once before winter.

Heat Pump Repair Questions from Mesquite Homeowners
What does heat pump repair cost in Mesquite?
Most bills land between $190 and $910, including the service call. A typical visit is about $590. Night and weekend calls cost more.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
