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.

1

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.

2

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.

3

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.

4

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.

Real reviews from
Phoenix homeowners

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.

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.

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.

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.
