When the Building Has to Stay Open, the Valley Calls Maricopa Air
A blown rooftop unit closes a business for the day. A failed split unit at a multi-tenant office means a frustrated tenant by lunch. In this climate, a cooling failure can shut a business down for the day, and we handle every call with that in mind.
Maricopa Air has worked commercial HVAC across the Valley since 1975 for small and mid-sized businesses: offices, retail, property portfolios, restaurants, and tenant improvement build-outs. We’ve kept OHSO Brewery’s locations running for years, and we bring that same standard to every business we work with.

Who We Work With
We work with a range of commercial clients, and each one needs something a little different.
Commercial tenants and owners. Single-building owners, office tenants, retail operators. Same response standard whether you operate one space or ten.
Property managers. Multi-property portfolios: offices, retail, multi-tenant industrial. One vendor across the portfolio means one point of contact and one standard.
General contractors and developers. Tenant improvement HVAC scopes and inspection on existing systems before build-out begins. We work to the GC’s schedule and coordinate with the designer or engineer on the drawings.
Restaurants and food & beverage operators. Kitchens, bars, and dining rooms across the Valley. When the kitchen or dining room has to be running, we’re a team you can call.

Restaurant & Kitchen Cooling.
Dining rooms and kitchens on the line all day put extra load on your rooftop units. We service and repair the cooling that keeps front and back of house running, scheduled around your service hours.

Why Maintenance Matters More Here
Commercial equipment in Phoenix runs in conditions few other US markets see. Rooftop units sit in direct sun on roofs that run far hotter than the air temperature, which pushes condensers harder than the forecast suggests. Triple-digit stretches that run May through September push duty cycles past what equipment was rated for. Monsoon dust loading clogs coils and filters faster than other markets.
Skipping maintenance on commercial equipment here usually just pushes the cost down the road. In our experience, units tend to give out on the busiest days, when they’re working hardest. Regular maintenance is the simplest way to avoid that.

FAQs
Commercial HVAC FAQs
Do you offer a maintenance plan or service agreement?
We set a maintenance cadence around your building and equipment. Call us to schedule a visit and we’ll build the schedule with you.
Can you handle multiple properties or locations?
Yes. We work with property managers and multi-location businesses across Scottsdale, Phoenix, and Maricopa County.
What equipment do you service?
Rooftop units, split units, mini-splits, VRF systems, and commercial refrigeration equipment, including walk-ins, reach-ins, bar coolers, ice machines, prep tables, and chillers. If it’s commercial cooling or refrigeration equipment and it runs in Phoenix, we work on it.
Do you do HVAC design or commissioning on new commercial installs?
We install and coordinate with your GC and designer on tenant improvement projects, but we don’t provide HVAC design or third-party commissioning services.
Do you work around restaurant service hours?
Yes. Restaurants and breweries have been part of our commercial work for decades, including OHSO Brewery’s locations, so maintenance gets scheduled before open or after close, and emergency calls get worked around the line.
Are you licensed and insured for commercial work?
Arizona ROC #366113. Bonded and insured. We dispatch EPA 608 certified technicians on every refrigerant call.
Should I repair or replace my commercial HVAC unit?
If it’s working, don’t replace it. But if there’s a leak and the unit is underperforming, it may be time to replace it. We’ll walk through the numbers with you on site.
