San Angelo Weather and HVAC Load
San Angelo logs 2,130 heating degree days and 2,785 cooling degree days in a normal year, based on the closest NOAA weather station. Neither season dominates in San Angelo. That balance is a big reason heat pumps and dual-fuel systems sell well in Texas. Count on roughly 49 nights below 32°F and 119 afternoons past 90°F in a typical year. Snowfall averages about 1 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 40,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Texas Permits, Efficiency Rules and Rebates
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). Plan on a mechanical permit for most replacements in San Angelo; the contractor normally pulls it. Before you sign, ask each bidder for their Texas license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- For a steam system, hire a contractor who works on steam regularly.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- A combi boiler frees up space and replaces your water heater.
