We handle commercial HVAC repair for Tucson storefronts, offices, restaurants, clinics, and small industrial buildings. Same repair-first approach we use on homes: find the actual fault, fix what is broken, and tell you plainly when a unit is no longer worth putting money into. One commercial HVAC contractor for the whole building — rooftop units, splits, and heat.
Commercial AC Repair in Tucson
Most calls we get are one of these. All of them cost you customers while the building is hot.
- Rooftop unit down. The single most common commercial failure in Tucson, and usually the fastest to diagnose.
- One zone hot, the rest fine. Often a damper, a thermostat, or a failed stage — not a dead unit.
- Short-cycling. The unit starts, runs briefly, shuts off. It never cools the space and it wears itself out.
- Breaker keeps tripping. Stop resetting it. Something electrical is drawing more than it should.
- Iced-up coil. Airflow or refrigerant. Both get worse if the unit keeps running.
- Water where it should not be. A blocked drain line on a rooftop unit can reach your ceiling tiles fast.

Text a photo of the unit and its data plate — it is the fastest way for us to show up with the right part.
Commercial HVAC Service We Provide
Rooftop & package units
Rooftop package units run nearly every Tucson commercial building. We repair them, replace failed components, and service them on a schedule so they are not failing in July. More on rooftop HVAC units →
Split and ducted systems
Offices and clinics built as converted space often run light commercial split systems. We service those the same way — airflow, charge, and controls checked together rather than one at a time.
Commercial HVAC maintenance
Tucson run hours are long. Filters load up faster here, belts stretch sooner, and coils pack with dust off the desert. A scheduled visit catches those before they become a no-cooling call on your busiest day.
Heating & heat pumps
Cold snaps are short here, which is exactly why commercial heat fails when it is finally needed. We check it before the season, not during. More on heating & heat pump repair →
How a Commercial Call Works
- You call or text. Tell us the building type and what it is doing. We give you a real arrival window.
- We diagnose. On the roof or at the unit, we find the actual fault instead of guessing at a part.
- You get the number in writing. Repair price, and the replacement number too if the unit is near the end.
- You approve it. Nothing gets done until you say go.
- We fix it and show you. What failed, why, and what will keep it from happening again.
Emergency service is available 24/7. For a building that is down right now, call rather than fill out the form.
Why Tucson Businesses Call Us
Choosing a commercial HVAC contractor in Tucson comes down to three things: who picks up the phone, who explains what failed, and who puts the number in writing first.
- Licensed and insured. AZ ROC #ROC-PENDING — verify any Arizona contractor at roc.az.gov.
- Repair-first. We are not looking to sell you a rooftop unit you do not need yet.
- Written quotes. You approve the price before work starts. No surprise invoice.
- Local response. We work Tucson and the surrounding communities, so the truck is not coming from Phoenix.
- Second opinions welcome. Got a replacement quote you are not sure about? We will look at it.

Commercial HVAC FAQ
Do you service commercial rooftop units in Tucson?
Yes. Rooftop package units are the most common setup we see on Tucson storefronts, offices, and small industrial buildings. We service them, repair them, and keep them on a maintenance schedule.
How fast can you get to a commercial no-cooling call?
Call us and we will give you a real arrival window, not a guess. Emergency service is available 24/7. If your building is losing business every hour it is down, say so when you call and we will tell you straight away where you sit in the queue.
Do you offer commercial HVAC maintenance agreements?
Yes. Most Tucson buildings need filters, belts, and coils looked at more often than the manufacturer schedule suggests, because our run hours are so long. We will build a schedule around your equipment and your budget and put the scope in writing.
Will I get a written quote before work starts?
Always. We diagnose first, then price the repair in writing. You approve the number before we touch anything. That applies to a single rooftop unit and to a full building.
