"Our AC died at 4pm on a Saturday in August. Cool Extreme picked up immediately, had a tech here by 5:30, and had us cool again by 7pm. Unbelievable service. They charged exactly what they quoted. Will never use anyone else."

"Had a full Trane system installed last spring. They were professional, cleaned up perfectly, and walked me through everything. My energy bill dropped by $180 the first month. The financing made it totally painless. Highly recommend."

"I've been on their maintenance plan for 2 years. My system is 12 years old but running better than it has in a decade. The annual tune-ups genuinely make a difference. And whenever I call, they actually pick up. That alone is worth it."

"After getting ripped off by another company, a friend referred me to Cool Extreme. Night and day difference. They were honest, on time, and the whole repair was under $200. Finally found my go-to HVAC company in Phoenix."

Our Story

Phoenix Born.
Comfort Driven.

Cool Extreme HVAC was founded in 2006 by Mike Ramirez — a third-generation HVAC technician who grew up watching his father and grandfather serve Phoenix families with pride and integrity.

Over 18 years, we've grown from a one-man operation to a 30-person team with a fleet of fully stocked service vehicles. But our values haven't changed. We show up on time, tell you the truth, charge fair prices, and stand behind every single job. That's the Cool Extreme way.

We're proud members of the Air Conditioning Contractors of America (ACCA), maintain an A+ rating with the Better Business Bureau, and our technicians hold NATE certification — the gold standard in HVAC training.

AC repair in Phoenix typically ranges from $150 to $600 depending on the issue. Minor repairs like capacitor replacement average $150–$250, refrigerant recharges run $200–$400, and compressor repairs can be $400–$1,200+. Cool Extreme offers free diagnostics with any paid repair and transparent flat-rate pricing — you know the cost before we start. Call for an accurate quote specific to your system.
Yes — we provide true 24/7 emergency HVAC service, 365 days a year including all holidays. When you call our emergency line, a live technician picks up (not a voicemail). We guarantee on-site response within 60 minutes in the Phoenix metro area. There are no additional weekend or after-hours surcharges on standard service calls.
In Phoenix's extreme desert climate, we recommend HVAC maintenance twice per year — once in spring (March–April) before peak cooling season, and once in fall (October–November) before heating season. Phoenix AC systems work harder than anywhere in the country. Twice-annual tune-ups extend equipment life by 5–10 years, improve efficiency by up to 30%, lower your electric bill, and catch small issues before they become expensive emergencies.
We install and service all major HVAC brands including Trane, Carrier, Lennox, Rheem, American Standard, Goodman, Ruud, Daikin, and more. As certified dealers for Trane and Carrier, we offer the best factory warranties on new installations. For repairs, our trucks carry parts for virtually every major brand — which means faster repairs with fewer return visits.
Absolutely. We offer 0% APR financing for 12–18 months on qualifying new HVAC system installations. We also work with multiple lenders for longer-term financing options for customers who need it. Additionally, we'll help you identify applicable manufacturer rebates and Arizona utility company incentives (APS, SRP) that can reduce your total cost by $500–$1,500. Ask us about current promotions when you call.
A standard residential AC system replacement takes 4–8 hours for most homes. Larger homes or more complex installations with duct modifications may take a full day. We typically schedule installations within 1–3 business days of your signed agreement. If your current system has completely failed during summer, ask about our emergency installation track — we'll do everything possible to get your system in the same day or next morning.
