What customers say about ac replacement
Called during the holidays to schedule an appointment and was promptly scheduled for review and replacement of unit. Deron, the sales technician was courteous, professional and advised on what was needed for our AC replacement. He reviewed all installation, parts and service with us and was extremely helpful. This gentleman is a great asset to the organization and enabled us to make the right decision for our requirements. Will definitely keep Beluga Air on my contact list for other requirements in the future. Thanks again to Deron for a reliable, executable solution.

What customers say about ac replacement
We have had issues with the AC unit for a while, and couldn't find anyone to help us or anyone that we could trust. I made one call to ASC and received an immediate response. Within a couple of days, we had a brand-new system. ASC answered all my questions and even checked back with me to make sure we were happy with our new AC. Their customer service goes above and beyond.
ASCs rep, JR, came out this week to give us a quote on replacing our whole HVAC system. worked with them for awhile and they were able to keep our old system going another year.

What customers say about ac replacement
The Rosenberg HVAC team replaced our heating and A/C system recently and we could not be happier with their work and their team. Joe, was great about answering questions throughout decision-making, and following up on details once we decided on the system. Edgar led the install team. He, Joaquin and Tomas were friendly and efficient, fully cleared and cleaned the work areas, and made sure we were satisfied with the install before they left. Our system is quiet and performing beautifully. Rosenberg is an honest, efficient, professional team and it was our pleasure to do business with them.

We are long time customers of Zimmermann A/C. They replaced our system a few years ago and this week Terry came out for the 'Routine Fall Maintenance'. He is an experienced professional with great attention to detail, clearly explaining everything, and a really nice person. I highly recommend Zimmermann for AC/heating!

What customers say about ac replacement
Nathan and Michael and their team did a phenomenal job with my AC installation. They came in and knocked out the job faster than what was initially quoted. They took the time to explain the system to me as well as how to properly maintain the system. Their professionalism is to be commended and their work quality is top tier. 5 stars isn't enough and would give 10 if I could. I will recommend these guys to everyone I know that needs a new AC or any AC work.

What customers say about ac replacement
Very impressed. I received a ridiculous quote from a different vendor and Felix provided a much more reasonable quote for replacing my AC unit, furnace, and duct work. Tony stayed in communication with me and the team arrived when they said they would and completed the install in the committed timeline. I will be using Felix in the future and will recommend to friends and family. Glad to have a cool house again.
Highly recommend Felix air services the owner and were really professional. They installed my new AC with affordable price and great work!

What customers say about ac replacement
We had a great experience with Goettl. Our AC unit was having multiple issues, and Jonathan Buhidar was the technician who came out. He was very professional, knowledgeable, and thorough. Jonathan replaced our fan motor and capacitor and also found and fixed a leak in the inside unit that had been improperly installed by another company (Radiant) about a year ago. He took the time to explain what was wrong, showed us the issues, and made sure everything was working properly before leaving. Our AC is running better than it has in a long time…

Typical AC Replacement costs in San Antonio, TX (2026)
Last updated
Estimated ranges for San Antonio, TX. Actual cost varies with home size, equipment, and scope — always request a written quote for your job.
| Service | Typical range |
|---|---|
| Full AC system replacement (3-ton, installed) | $4,300–$10,800 |
| R-454B equipment upcharge (vs equivalent R-410A tier) | $345–$1,050 |
| SEER2 17+ high-efficiency upcharge (utility rebate tier) | $690–$2,150 |
| Ductwork modification (resize / re-balance per Manual D) | $520–$1,900 |
2026 note on equipment: All new residential AC equipment manufactured after Jan 2025 uses R-454B refrigerant — if a contractor is still quoting R-410A new installs in 2026, ask why (likely old inventory). Federal Section 25C tax credit expired Dec 31, 2025, so state and utility rebates are the surviving incentives; SEER2 17+ models typically unlock $500–$1,200 in utility rebates (Oncor, CPS, SRP, etc.) — confirm directly with your utility before pricing the install.
R-454B refrigerant in 2026: what San Antonio AC replacement buyers need to know
All new residential AC and heat-pump equipment manufactured after Jan 1, 2025 uses R-454B refrigerant — the EPA AIM Act phase-down replaces R-410A (global warming potential 2,088) with R-454B (GWP 466). If a contractor in San Antonio quotes R-410A new equipment in 2026, ask why: it's almost certainly discontinued inventory, and you'd be locked into a refrigerant scheduled for full phaseout by 2032.
R-454B is not drop-in compatible with R-410A — different operating pressures, different POE lubricants, different leak-test procedure. Equipment-side cost runs about $400–$1,200 over the equivalent R-410A tier (see the pricing table above). The bigger consideration is contractor capability: R-454B is mildly flammable (A2L classification), so leak detection, brazing, and recovery practices changed in 2025 — your installer needs A2L-specific training, not just EPA 608 Universal.
Before signing an R-454B install quote, ask each contractor:
- Is your technician certified on A2L refrigerants by the manufacturer? Carrier, Trane, Lennox, Rheem, and York all run dealer A2L courses — generic EPA 608 isn't enough for safe 2026 install practice.
- What leak detector are you using on this install? Older R-410A-only detectors miss R-454B leaks. You want an A2L-rated infrared or heated-diode unit.
- How will warranty refrigerant be sourced if there is a mid-cycle supply disruption? R-454B is the long-term residential standard, but ask how the dealer would source it 2027–2028 if a supply shock hits — a documented supplier chain beats a verbal assurance.
What You Need to Know Before Scheduling HVAC Service in San Antonio
- What's the federal minimum SEER2 rating for a new AC in 2026?
- 14.3 SEER2 in southern states (FL, TX, AZ, CA, GA, NV, NM), 13.4 SEER2 in northern states. Anything sold new in 2026 meets at least that floor; the choice is whether to pay for 15.2+ to qualify for utility-rebate tiers and lower bills.
- The federal Section 25C tax credit expired — what incentives are left?
- 25C and 25D expired December 31, 2025. The surviving residential incentives are state and utility rebates (Oncor, SRP, APS, CenterPoint, Mass Save, etc.) plus state HEEHRA programs where active. Confirm any rebate the installer cites is a current state or utility program, not the lapsed federal credit.
- Do I need a city permit for HVAC system replacements in San Antonio?
- Yes, major HVAC system replacements in San Antonio typically require a mechanical permit to ensure the installation meets local building codes. Licensed contractors are responsible for obtaining these permits and scheduling the necessary inspections upon completion. Homeowners should request confirmation that the permit process has been initiated to guarantee the work remains compliant with municipal safety standards.
- How can I find affordable HVAC services in San Antonio, TX, without sacrificing quality?
- Look for providers who offer transparent, itemized estimates and maintain long-standing reputations within the San Antonio area. While searching for affordable HVAC services in San Antonio, TX, prioritize companies that hold manufacturer-dealer designations and NATE certifications, as these indicate a commitment to standardized, high-quality workmanship. Comparing multiple detailed quotes can help you identify a fair price while ensuring the contractor carries the necessary liability insurance and workers' compensation coverage.
- How do I identify a specialist for high-efficiency cooling in San Antonio?
- Identify a specialist by looking for providers who hold specific manufacturer-dealer designations and demonstrate extensive experience with modern, high-efficiency systems. Review sites often highlight companies that show expertise in smart thermostat integration and indoor air quality solutions, which are common requirements for newer homes in neighborhoods like Stone Oak or Helotes. Ensure the contractor provides proof of NATE certification to confirm their proficiency with advanced cooling technology.
- Typical HVAC pricing in San Antonio, TX: what should I budget?
- Full AC system replacement typically runs $4,300–$10,800 in San Antonio, Texas. See the HVAC pricing table on this page for the full per-service breakdown.
