What Phoenix Homeowners Say
89 five-star Google reviews from real families keeping cool in the Valley of the Sun.
"Our AC died on a 115-degree July day. Summit had a tech at our door in 45 minutes, diagnosed a failed compressor on the spot, and had a brand-new Trane installed the very next morning. Absolute life savers in the desert."
"Summit replaced our old 3-ton unit with a 20 SEER2 heat pump. Our summer electric bill dropped from $380 to $240 — every single month. They also sealed all the ductwork in the attic. Night and day difference."
"Three years on their maintenance plan. Twice-yearly tune-ups, always on time, priority scheduling when I need it, and 15% off repairs. My 12-year-old system still runs like it's brand new. Best HVAC company in the Valley."
"Had an indoor air quality system installed for my daughter who has severe allergies. The difference was dramatic within two weeks — dust is gone, no more stuffy mornings. Worth every penny and Summit's team was incredibly professional."
"Summit replaced a rooftop unit on our restaurant with almost zero business disruption — they worked overnight and had us back up by morning rush. Commercial HVAC done right. Their maintenance contract has been flawless ever since."

How much does a new AC system cost in Phoenix?
A complete AC replacement in Phoenix typically runs $4,500–$12,000 depending on your home's square footage, the efficiency rating (SEER2), and the brand you choose. We provide a detailed upfront flat-rate quote before any work begins — no surprises.
Do you offer financing for HVAC equipment?
Yes. We offer 0% APR financing for up to 60 months through Wells Fargo Home Projects, subject to credit approval. You can apply in minutes during your appointment and get a decision the same day.
What is included in the $14.99/month maintenance plan?
Two full precision tune-ups per year (spring and fall), priority emergency scheduling, 15% off all repairs and parts, filter replacement at each visit, and a full system inspection report. It's the single best investment you can make in equipment longevity.
