What customers say about ac replacement
…The dispatcher was very kind and understanding, the technician was respectful and left everything clean, and the Sales Manager, Reece, impressed me with his deep knowledge of HVAC systems. His low-pressure, honest approach helped me feel confident in deciding to replace my old unit with an amazing new system for me and my family. Plus, he even spoke a bit of Spanish with us, which made the experience feel more personal. I’m so thankful that we have AC again! I highly recommend The Coolest for their professionalism, kindness, and quality work…

SAS does a great job of assessing and repairing AC issues for good price. Strand Brothers had installed new ac unit and mis-aligned the drain pan causing water over flow onto kitchen ceiling. SAS installed new pan and overflow pipes to correct issue.
We hired Strategic Air Services to install a new HVAC system and replace our ductwork. The pricing was reasonable, and while we hit a bit of turbulence along the way, the customer service ultimately proved to be excellent. I want to specifically mention Chad, who led the installation. A significant part of my day job is to find and fix the mistakes other engineers make. From that perspective, Chad exhibited excellent craftsmanship and an impressive drive to ensure quality work. Highly recommended.

Last year, I hired Atlas AC to replace my broken air conditioning unit with a heat pump. The price was reasonable, the work was done well, and the handling of our service needs was very nice and professional. This winter (2026), the unit shook a lot, scaring my tenants. I had Atlas AC come to the house and investigate it, for free because it was still under warranty. The tech Jose was very informative, informing me that the shaking is unavoidable and why it occurs. He checked the balance of the unit and the fan to ensure they were up to standards…
Brandon and Delwis Graterol did a great job installing my new AC system. They were very professional and knowledgeable in their field. I would recommend them for your next AC/ heating system repair or installation

Stan's is great. They are quick to resolve issues with my AC, most recently a total and complete AC replacement. This job costed near $16,000 and Stan's guys had it up and in the attic, all new ducting, and an outside unit installed in about seven hours. The only reason I wouldn't give them five stars, is a small hiccup caused by a hardware issue. I don't blame Stan's for the hardware issue that they resolved in 48 hours. I wasn't a huge fan of being asked for payment when my AC wasn't working…

The folks at A-Plus live up to their moniker, truly A+ work! The whole team was professional but down-to-earth, answered every question well, and practically held my hand through the whole process. We had a brand new high-efficiency HVAC system installed, replacing the original 28-year-old system. It was a lot of work, but all turned out excellent. Working with A-Plus was so great, it almost makes me wish I could get another HVAC system! Kudos to them, I highly recommend A-Plus!

…After troubleshooting, a problem was found with the unit inside my house. Omar gave a fair estimate to repair the problem but, after weighing that cost with the age of the unit, we thought it would be best to replace it. The estimate for replacing the unit was fair, and we decided to move forward. In order to maximize time, being as efficient as possible, they suggested removing the old unit immediately and preparing my furnace closet for the new installation…

What customers say about ac replacement
We recently had a new air conditioning unit installed and could not be happier with the experience. We shopped around quite a bit before making a decision, and this company stood out immediately for their honesty and transparency. No pressure, no gimmicks — just straightforward information and fair pricing. Our technician, Elton Stewart, was fantastic. He was kind, professional, and took the time to explain everything clearly. You can tell he genuinely cares about doing the job right. The installation went smoothly, and everything is working perfectly…
…He is always professional, polite and friendly. I took advantage of signing up for the spring and winter checkups for next year to secure a place in line. When it comes time to replace my air conditioner and gas heater I will get Elton’s input and already plan on having him do the installation

…Throughout the day he would check in with me and let me know where they were at. They ran into some issues which wasn't their fault but my cheap builder but was able to take care of everything. It was a long day for them especially on a Saturday but they got everything done. Now my new ac is up and running and so much nicer. Jose was polite respectful and very professional. If you are going to get precision to do any ac work make sure you ask for jose to be the tech

BEWARE: In 2021 when we had to replace our hot water heater and HVAC we contacted Strand Bro. When we were explained the Advantage Program it was communicated as a service to have maintenance at no charge in no way did we understand the Advantage Program is actually a LEASE program.

Typical AC Replacement costs in Austin, TX (2026)
Last updated
Estimated ranges for Austin, 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) | $4,600–$11,500 |
| R-454B equipment upcharge (vs equivalent R-410A tier) | $370–$1,100 |
| SEER2 17+ high-efficiency upcharge (utility rebate tier) | $735–$2,300 |
| Ductwork modification (resize / re-balance per Manual D) | $555–$2,050 |
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.
Why Austin's Extreme Heat Cycles Demand Specialized HVAC Care
Intense summer temperatures and unpredictable winter freezes place extreme strain on residential climate systems, making it vital to find the best hvac companies in austin tx for your home. Whether you reside in historic Hyde Park, modern Mueller, or the neighborhoods of South Congress and Zilker, professional HVAC services in Austin, Texas help ensure reliable comfort and system efficiency year-round.
R-454B refrigerant in 2026: what Austin 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 Austin 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.
Austin HVAC: Costs, Timing & Licensing, Answered
- 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.
- Is a city-issued permit required for HVAC system replacements in Austin?
- Yes, the City of Austin Development Services Department mandates specific permits for major HVAC system replacements to ensure all work meets current safety and energy-efficiency codes. Licensed contractors typically manage this permitting process as part of their service, which helps homeowners avoid future compliance issues or insurance complications. Always confirm that your chosen provider includes permit filing in their project scope before beginning installation.
- What should I look for when choosing a high-efficiency HVAC specialist in Austin?
- When seeking a high-efficiency specialist, look for providers who hold NATE certifications and maintain authorized dealer status with major equipment manufacturers. These professionals demonstrate a deeper understanding of how modern, energy-efficient systems integrate with the specific electrical configurations found in older homes throughout Tarrytown and Travis Heights. Reviewer evidence of successful high-efficiency installations often serves as a strong indicator of a company's technical proficiency in these specialized projects.
- Typical HVAC pricing in Austin, TX: what should I budget?
- Full AC system replacement typically runs $4,600–$11,500 in Austin, Texas. See the HVAC pricing table on this page for the full per-service breakdown.
