How it works

Certified HVAC dispatch
in 4 steps

KoolFyx removes every friction point between a broken AC and a verified fix — no phone tag, no mystery pricing, no pressure.

Tell us your AC brand and problem

Pick your brand (Carrier, Trane, etc.) and describe the issue. Our system instantly shows you a price estimate range and matches only FAD/TCS contractors certified for your specific brand.

Pick a verified contractor

See each contractor's CSS Trust Score, certifications, and AZ ROC licence number — all verified at the source. Choose who comes to your home. No surprises.

Tech arrives, diagnoses, sends you a quote

Your $35 diagnostic fee is the only charge until you approve a repair. The tech diagnoses the fault and sends an itemised quote to your phone — parts and labour shown separately.

You approve — or walk away

Accept the quote and the tech fixes it immediately. Decline and pay only $35. No pressure, no drama, no second charges. Every time.

What homeowners say

Real reviews from
Phoenix homeowners

It was 114 degrees and my AC died at 2pm. I booked KoolFyx, the tech arrived in 28 minutes, diagnosed a failed capacitor, sent me a quote on my phone, and had it fixed before 4pm. The whole thing cost me $223 and I approved every dollar before they touched anything. This is how it should work.

Sarah K.

Scottsdale, AZ · Carrier 5-ton

Capacitor repair

I was worried about being overcharged. With KoolFyx, I saw the exact quote on my phone — part cost and labour, separate line items — before I approved anything. Trane Comfort Specialist came out, charged my refrigerant, and my unit has been running perfectly since.

Marcus P.

Gilbert, AZ · Trane 4-ton

Refrigerant recharge

The Carrier FAD badge on the contractor profile was the deciding factor for me. My unit is under warranty and I needed a factory-authorised tech. Booked, contractor arrived in 25 minutes, fixed the contactor, warranty stayed intact. Worth every penny of the $35.

Linda R.

Contactor replace

Used three different HVAC companies over the years and always felt like I was being taken advantage of. KoolFyx showed me the AZ ROC licence number, the CSS Trust Score, and sent me an itemised quote. That's what trust looks like.

Annual tune-up

My elderly mother lives alone in Mesa and her AC died on a Saturday afternoon in July. I booked KoolFyx from 2 states away on my phone, tracked the tech live on the map, and got a notification the moment it was fixed. Game-changing for families caring for elderly parents in Phoenix.

Amy T.

Mesa, AZ (booked remotely)

Emergency repair

I declined the first quote because it felt high. The tech left, no drama, no pressure. I paid my $35, got a second opinion, came back and it was actually fair. But the point is — KoolFyx lets you say no. That alone is worth using them over anyone else in Phoenix.
