Frequently asked questions
How much does it cost to replace an air conditioner in San Antonio?
A central air conditioner replacement in San Antonio generally costs $4,000 to $7,500 installed. If you're replacing the furnace at the same time, budget $7,500 to $13,000 for the complete AC-and-gas-furnace system. Simple like-for-like swaps with usable existing ductwork sit toward the lower half of those ranges.
Is a heat pump a good choice for San Antonio's climate?
San Antonio sits in climate zone 2, where winters are mild and heating loads are light, so a heat pump can handle both cooling and heating without much need for backup heat. Installed costs run $6,000 to $12,000, which is higher than a straight AC at $4,000 to $7,500, but it replaces your heating equipment at the same time. Compare that against the $7,500 to $13,000 range for a separate AC and gas furnace pair.
Do I need a permit to replace my HVAC system in San Antonio?
Yes — mechanical permits are standard for equipment replacement, and they typically run $75 to $300 in the San Antonio area. Your contractor should pull the permit and schedule the inspection as part of the job, so ask whether the fee is already in your quote or billed separately.
What license should a San Antonio HVAC contractor have?
HVAC contractors in Texas must hold a TACLA or TACLB license issued by the Texas Department of Licensing and Regulation. Ask for the license number and verify it before signing anything. It's also worth asking your installer about Oncor residential HVAC incentives, which are offered through participating contractors and vary by system.
Are there rebates available for a new HVAC system near San Antonio?
Rebate amounts vary by system and by utility. Oncor offers residential HVAC incentives through participating contractors, and Austin Energy runs its own home HVAC rebate program for customers in its service territory. Check eligibility before you sign, since some incentives require the paperwork to be filed by the installing contractor.
