Celina Housing Stock
Half the homes in Celina were built before 2012 (Census ACS median), so the typical house is about 14 years old. Newer homes are built tighter, so oversized equipment is a common problem. It short-cycles, wastes energy and leaves rooms clammy. Celina has roughly 7,800 owner-occupied homes, or 93.2% of households. Homes here have a median value of $458,000 and households a median income of $155,875. Those two numbers drive the labor adjustment in our estimate.
Collin County had 39 hail days and 27 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 3 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Collin County also had 6 tornado days in that period.

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
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
- Ask what the emergency fee is before the truck is sent.
