Larson Air Conditioning has stood out in dealing with a previous complaint I had with their installation of a new AC unit on my condo. They have gone to considerable lengths to honor their commitment to provide excellent service and regain my approval of their services.
They did a great job installing my new ac unit and were very polite. Would recommend.

What customers say about ac replacement
I love this company. We have used them for complete A/C replacement, plumbing repairs and recently a hot water replacement, for years. They have been in business for many years with a great reputation. Our last replacement of the water heater, was done professionally and with a complete explanation and quote prior to beginning by Matt. He did a perfect job in a timely manner and left the area clean. I highly recommend them for your plumbing and A/C problems.

I had to get a brand new AC unit for my investment property and multiple people recommended I go to Cooling Specialists, and I’m so glad I did! They were very honest, knowledgeable, and efficient. My unit works amazing and you can clearly tell it was installed with attention to detail & care. Definitely recommend them for anyone in the PHX area needed HVAC services.

Typical AC Replacement costs in Scottsdale, AZ (2026)
Last updated
Estimated ranges for Scottsdale, 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 Scottsdale 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 Scottsdale 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 Scottsdale Property Owner Should Ask Before Booking
- 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 Scottsdale HVAC contractors need a specific state license to perform residential repairs?
- Yes, all HVAC contractors operating in Scottsdale must hold a valid license issued by the Arizona Registrar of Contractors. This state-level requirement ensures that technicians possess the necessary training and insurance coverage to perform residential cooling work safely. Before hiring any company, verify their current license status through the official Registrar of Contractors database to confirm they are authorized to work on your home.
- How do I find a qualified mini-split specialist in Scottsdale?
- To find a qualified mini-split specialist in Scottsdale, look for providers who maintain manufacturer-specific certifications and demonstrate extensive experience with high-efficiency ductless systems. Reviewer feedback often highlights companies that specialize in these installations for older homes in areas like McCormick Ranch or modern, compact builds. Verify that the provider has dedicated equipment for these units and check for NATE-certified technicians on staff to ensure the installation meets high technical standards.
- What factors most affect HVAC service pricing in Scottsdale?
- HVAC service pricing in Scottsdale is primarily influenced by the age of the housing stock, the complexity of the cooling system, and current seasonal demand. Older homes in neighborhoods like McCormick Ranch may require more involved retrofits or specialized parts compared to newer, energy-efficient builds in Grayhawk. Additionally, scheduling repairs during peak summer months can lead to higher demand, while emergency after-hours requests typically carry different rate structures than standard maintenance appointments.
- What does HVAC service typically run in Scottsdale, AZ?
- Full AC system replacement typically runs $5,200–$12,100 in Scottsdale, Arizona. See the HVAC pricing table on this page for the full per-service breakdown.
