What customers say about ac replacement
Our experience with John's was nothing short of incredible. Shawn did an awesome job asking the right questions and evaluating our home to get us into the right HVAC unit for us. Justin and his team made the install look easy! No AC in the summer is a nightmare, but John's was able to come out same day to review our home and the new AC was installed less than 48hrs later. Great communication, timely service, and transparent selling. Can't recommend them enough!

…I waited 6 years to replace it and every year, they said, it might break. It didn't. I just couldn't risk it this summer so I went ahead and replaced it. I spoke to Joe who I made the deal with. He was upfront and gave me a very fair deal. The technicians came out and replaced the ac like a pro. It was a very clean job. I cant imagine what they had to go through to get access to my unit but they did. I would have given a 4 stars just because part of my deal with Joe, they will update my thermostat so it is compatible with my sensi app…

I was a little nervous calling a different/ new A/C company, but when ASAP pulled up, Travis greated us with a big hello and a smile. He went to our A/C unit and quickly came back with,"I've got good news". This was music to our ears, because our A/C is older and we thought that we would be spending thousands for a new unit. We only spent less than $300 and he checked out our unit and was done in no time at all. We love ❤️ Travis and would use both in the future!! It's a good day when you save $.
ASAP's installers Ivan and Ricky installed my AC unit in under 4 hours and it was up and runnning, resulting in very little down time. I was very impressed with their professionalism and how they treated me and answered my questions. I highly recommend their services. Its great to work with motivated and highly professional people, which are hard to find in today's work place

I had Everest Air handle a fairly involved project at my home, including replacing my water heater, installing attic insulation, insulating the header above my garage door, and making several HVAC improvements. This included replacing the roof jack, elbow, and stand, upgrading the ductwork to an over-under drop setup, and adding a new return in the master bedroom to improve airflow and efficiency. As with any larger project, a few issues came up along the way, but what really stood out was how quickly and professionally they were addressed…
We knew we were going to need a new AC system when we purchased our house in 2020. Everest Air was recommended to us from a close friend and they have been fantastic. Since 2020, our 20-year-old system has been dying slowly but Everest Air has always been able to put a band-aid on it until this last summer (unit finally died). After shopping many different companies (including Costco’s Collin’s Comfort), we went with Everest as their service is unmatched and their prices are extremely competitive. The process was very low-pressure and we are so glad we went with them…

We used Martin Air for several things involving our new home. They performed a full and thorough inspection before the purchase. They showed us things we would never notice. After purchase, they installed one completely new AC unit, and performed maintenance on the other 2 units. One existing unit needed leveling from a previous poor install, no issue for these guys. We had questions about filter replacement frequency, and how to manage the house temp with 3 AC units. They walked us through everything with no rush…
When the AC goes out in your house, the most important thing to me is responsiveness. Colter came over with a real solution, which ended up being replacing the entire outside condenser unit. Every other bid I had wanted me to replace the entire AC unit. We came to an agreement at 4:30 PM and he had the new unit in before dark. I hardly ever do reviews, but this is one I am happy to do. I highly recommend Martin Air, especially during the summer months in Arizona.

We had a new AC system installed by Rusty’s Air Conditioning & Heating and couldn’t be happier. What really stood out is that they’re a local company—you can feel the difference compared to larger HVAC companies. Richard helped us choose the right options, and Jose and the install crew were professional, respectful of our home, and very clean. Highly recommend Rusty’s if you want honest service and quality work
…Our home is already more comfortable, quieter, and noticeably more efficient. It’s refreshing to work with a local company that values quality, communication, and craftsmanship. If you’re considering a new AC system or want a company you can actually trust, I highly recommend Rusty’s. Top-notch work all around

Robert was professional and thorough. He was also friendly and was respectful of my husband healing from surgery. Sally in the office is always friendly and helpful. The technicians recognize her value as well. They also replaced our system last year. I greatly appreciate this company does not pressure for unnecessary service, they give honest recommendations but no pressure

They replaced my 46 yr old whirlpool AC with a Bosch unit and revised our ducting to cool down the kitchen which wasnt getting enough cool air. All went well and the install was completed in one long day.

They did such a fantastic job at my house that when it came time to replace the air conditioner at my grandmother’s house I had no problem recommending them to a 90 year old widow. I knew that Blake and his guys work clean and are honest. Karla in the office is great. She was quick to respond and follow up on emails. All in all a great experience. I appreciate the no BS non-sales approach and I’d highly recommend them.
From the owner to the office team and service team Peavler AC has been great every time! They have helped me an aging AC unit and finally a new AC and thermostat. They have also helped my mom and neighbors!

Typical AC Replacement costs in mesa, AZ (2026)
Last updated
Estimated ranges for mesa, AZ. 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) | $5,200–$12,100 |
| R-454B equipment upcharge (vs equivalent R-410A tier) | $360–$1,100 |
| SEER2 17+ high-efficiency upcharge (utility rebate tier) | $720–$2,250 |
| Ductwork modification (resize / re-balance per Manual D) | $540–$1,950 |
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 mesa 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 mesa 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 Every Mesa Resident Should Ask Before Booking HVAC Service
- 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.
- How do I find a reliable HVAC specialist for high-efficiency system installs in Mesa?
- Look for providers who maintain active manufacturer-dealer certifications, as these designations indicate that the company undergoes specialized training for high-efficiency equipment. When researching local hvac reviews in Mesa, AZ, prioritize feedback that mentions precise calibration and proper ductwork sealing, which are critical for performance in our climate. Trusted hvac near Mesa, Arizona, experts often showcase their technical credentials and provide clear, documented installation protocols rather than just offering low-cost estimates.
- How can I find affordable HVAC services in Mesa, AZ without sacrificing quality?
- Affordability in the Mesa market is best measured by the long-term efficiency and reliability of your system rather than just the initial service call price. Consider providers who offer transparent, itemized quotes and have a proven track record of accurate diagnostics to avoid unnecessary repairs. Many homeowners find that choosing a licensed, established contractor prevents the high costs associated with improper installations or recurring equipment failures caused by the intense local heat.
- Why does Mesa's desert environment require specialized HVAC installation protocols?
- The extreme heat and constant dust accumulation in Mesa place unique stress on cooling components that standard installation methods may not address. Qualified technicians in neighborhoods like Red Mountain and Dobson Ranch utilize specific shielding and filtration techniques to prevent premature system degradation. Proper installation in this climate requires precise refrigerant charging and airflow balancing to ensure your system can maintain indoor comfort when outdoor temperatures regularly exceed 115°F.
- How much does HVAC service cost in mesa, AZ?
- Full AC system replacement typically runs $5,200–$12,100 in mesa, Arizona. See the HVAC pricing table on this page for the full per-service breakdown.
