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. On the cooling side, a 2,000 sq ft house here usually needs around 3.5 tons. A tight, well-insulated house may get by with half a ton less.

The median home value is $179,300, and median household income is $64,146. We use both figures to adjust labor and pricing for this page.
Tom Green County had 31 hail days and 53 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 4 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.
When It Makes Sense
- It still runs on R-22 refrigerant
- The AC is 12 to 15 years old or more
- Summer electric bills keep going up
- It has had more than one refrigerant leak
What Moves the Price
- Tonnage, based on house size and local climate
- Whether the coil and line set also need replacing
- The pad, permit and refrigerant (R-410A or the newer R-454B)
- SEER2 rating and whether the compressor is single-stage or variable-speed
- Electrical work such as a new disconnect, breaker or wiring
We kept the national figures close to unchanged for San Angelo using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- The new condenser, coil and, if needed, line set
- The electrical disconnect and wiring
- Refrigerant charge and a leak test
- Startup, an airflow check and warranty registration
- Removing the old condenser and coil
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
- Fall and early spring installs often come with better pricing and shorter waits.
- Ask for a Manual J calculation. "Same size as the old one" isn't sizing.
- Buy the condenser and coil as a matched set, or you may void the manufacturer warranty.
