Built for the roof
Everything in a rooftop unit lives in one cabinet: compressor, coils, blower and controls, baking in the sun and sandblasted by monsoon dust. One weak part can shut the whole thing down.
Our technicians work on commercial roofs every week. We check the entire unit, not just the part that failed, because one failure often points to the next one. You hear what is wrong and what it costs before we touch a wrench.

Rooftop reality
Phoenix Roofs Are the Hottest Place Your HVAC Can Live
A rooftop unit sits in direct sun through months of 100 degree days. Summer storms and haboobs then pack the condenser coil with dust, bend fins and throw debris into fans.
After a big storm, have the coils cleaned and the cabinet checked. A dirty coil makes the compressor work hardest at the hottest time of year.

Repair or replace?
Most Rooftop Units Can Be Repaired
Replacement is worth talking about only when the numbers point that way. When it is, we plan the crane lift, curb connection and startup so you are without cooling for as short a time as possible.
Repair it when
- The unit is mid-life and maintained
- The fault is a capacitor, belt, motor or control
- Coils and cabinet are in decent shape
- It cooled the space fine last summer
Consider replacing when
- An aging unit loses its compressor
- It runs on outdated R-22
- Breakdowns keep coming back
- Rust has eaten into the cabinet
Crane lifts are planned around your hours. Ask about replacement scheduling at (602) 266-9566.

FAQ
Rooftop Unit Questions
What is a rooftop unit?
An RTU or package unit holds the compressor, coils, blower and controls in one cabinet on the roof and sends cooled air down through ductwork.
What are the signs my rooftop unit needs repair?
Warm air, weak airflow, a unit that never stops running, water through the ceiling or a breaker that keeps tripping.
Can a rooftop unit be repaired instead of replaced?
Usually, yes. Most problems are capacitors, belts, motors, controls or leaks. We recommend replacement only when an old compressor fails or breakdowns keep repeating.
Do you handle crane lifts?
Yes. When a unit needs replacing, we plan the crane lift, curb connection and startup.
Can you work before we open?
Yes. We work 24 hours a day, Monday to Saturday, so repairs can often happen before opening or after closing.
Do you offer rooftop maintenance?
Yes. Coil cleaning, belt and filter changes, electrical checks and drain cleaning, scheduled around your business.
