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.

San Angelo Housing Stock
The median San Angelo home dates to 1977, according to the Census ACS. That makes the typical house about 49 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. San Angelo has roughly 25,000 owner-occupied homes, or 63.3% of households. 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 Replacement Makes Sense
- A repair quote runs past a third of the cost of a new unit
- The furnace is 15 to 20 years old or more
- A tech found a cracked heat exchanger, or the CO detector has gone off
- Gas or electric bills keep climbing even though usage hasn't changed
What Moves the Price
- Single-stage, two-stage or modulating gas valve
- Condition of the existing ductwork and any changes it needs
- New PVC venting if you move to a condensing model
- BTU size, which should come from a Manual J load calculation
- Permit and inspection fees, which the local building department sets
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
We lowered the national figures about 14% 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 furnace, filter rack and thermostat wiring
- Combustion and safety tests
- Gas line and vent connections
- The permit and the manufacturer warranty registration
- Removing and hauling away the old furnace
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
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.
- Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
