San Antonio Weather and HVAC Load
In a normal year, San Antonio racks up 1,527 heating and 2,994 cooling degree days (NOAA 1991-2020 normals). Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. On average, San Antonio gets 22 freezing nights and 112 days above 90°F per year. For a 2,000 sq ft house, this climate points to a heating load somewhere near 35,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 1,527 |
|---|---|
| Cooling degree days / year | 2,994 |
| Nights at or below 32°F | 22 |

San Antonio Housing Stock
Half the homes in San Antonio were built before 1984 (Census ACS median), so the typical house is about 42 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. Owners live in 52.4% of occupied homes, roughly 287,000 households. With a median household income of $62,917 and a median home value of $219,700, local labor rates come out near the national middle in our model.
NOAA storm reports for Bexar County show 35 hail days and 24 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 5.5 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. Bexar County also had 2 tornado days in that period.
When It Makes Sense
- There's no natural gas service on your street
- Energy bills are higher than you want them to be
- Your AC needs replacing, and you'd like cheaper heat at the same time
What Moves the Price
- Size in tons, and whether the unit is cold-climate rated
- Variable-speed (inverter) or single-stage compressor
- Electrical panel capacity and wiring
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- A ducted system or a ductless mini-split
We raised the national figures about 6% for San Antonio 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
- A load calculation and equipment selection
- The outdoor heat pump and an indoor air handler or coil
- Line set, drain and electrical hookups
- Commissioning and warranty registration
- Thermostat setup and backup heat settings
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). Equipment replacements in San Antonio generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Texas license or registration number and a certificate of insurance with the quote. 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
- A dual-fuel setup keeps your gas furnace as backup for the coldest nights.
- Make sure the installer sized the system for your heating load, not only cooling.
- Where winters get cold, ask for a model on the NEEP cold-climate list.

Heat Pump Installation Questions from San Antonio Homeowners
How much is heat pump installation in San Antonio?
Plan on $5,800 to $14,300, with most jobs near $10,500. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule heat pump installation in San Antonio?
Between late fall and early spring. With 112 days over 90°F, San Antonio contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
