San Antonio HVAC Runs Harder Than Most Cities
San Antonio sits in a subtropical climate zone. Your AC runs 7–8 months per year — far more than systems in most U.S. cities. That extra runtime means more wear, higher energy bills and shorter system lifespans.
CPS Energy serves the entire metro. Their residential HVAC program offers $500–$2,500 toward new high-efficiency systems. Combined with federal tax credits of up to $2,000 for heat pumps, you can offset a big chunk of replacement costs.
The military presence shapes the market too. Joint Base San Antonio brings thousands of families who need HVAC service fast — often moving into older homes with aging systems.

From real SA homeowners
"AC went out on a Friday night in August. Emergency tech showed up by 9pm — turned out to be a blown contactor. $195 and back to cold air. Can't ask for better than that."
"Moved here from Colorado and had no idea who to call. Got matched with a company near Helotes. They found a bad capacitor before it failed."
"Replaced our 15-year-old system. Got the CPS Energy rebate and federal tax credit — saved about $3,800 total. The contractor handled all the paperwork."

San Antonio HVAC Questions
How much does AC repair cost in San Antonio without a service contract?
Expect $150–$650 for most repairs. The diagnostic call alone runs $75–$150, which usually gets credited toward the repair. Capacitors ($120–$475) and contactors ($100–$350) are the most common fixes. If your system needs refrigerant, that adds $150–$600 depending on the type and amount. Compressor replacement is the big one at $1,500–$2,800.
When should I replace my AC instead of repairing it?
Replace if your system is over 12 years old and needs a repair costing more than 50% of a new unit. Also replace if it uses R-22 refrigerant (phased out) or if you're spending $500+ per year on repairs. A new 16 SEER2 system runs $4,200–$8,000 installed and qualifies for CPS Energy rebates of $500–$2,500 plus potential federal tax credits.
What CPS Energy rebates can I get for a new AC?
CPS Energy offers $500–$2,500 in rebates depending on system efficiency. Heat pumps qualify for the highest rebates. You must use a CPS Energy-approved contractor. Federal tax credits add up to $2,000 for qualifying heat pump systems. Between rebates and tax credits, you could offset $2,500–$4,500 of a new system's cost.
How fast can I get emergency AC repair in San Antonio?
During summer peak (June–August), emergency response times average 2–4 hours for most providers. Off-peak, you can often get same-day service within 1–2 hours. After-hours and weekend calls carry a $50–$150 surcharge. Our matching service connects you with available contractors immediately — fill out the form above.
Why is my electric bill so high in summer?
San Antonio summers push AC systems hard. Average summer CPS Energy bills run $200–$400 for a 2,000 sq ft home. Old or inefficient systems, leaky ductwork, poor insulation and a dirty air filter all make it worse. A tune-up ($75–$150) and duct sealing ($300–$1,500) can cut cooling costs 15–30%. Upgrading to a higher SEER2 system reduces bills long-term.
