Light commercial
Commercial HVAC in NJ & NY
We keep tenants and residents comfortable in the kind of buildings that make up Main Street New Jersey: strip malls, professional plazas, apartment buildings and retail build-outs.
That means rooftop packaged units, splits, and the new installs that come with a tenant fit-out or an addition. Your storefront or building gets an owner who actually cares that it's done right.

What's included
What we cover
Rooftop packaged unit (RTU) install, replacement and service
Strip malls, plazas and professional/medical offices
Small apartment buildings and multi-unit residential
Tenant build-outs and fit-outs for new retail space
Additions and light-commercial new construction
Scheduled maintenance to keep units off the roof and off your mind
Right-sized for the job
Right-sized for commercial
A 21-unit apartment building, a six-store plaza, a dentist's office build-out — we handle them right. We'll coordinate with your GC on a build-out or work directly with the property owner on a replacement.
Maintenance contracts keep rooftop units running through the seasons so a failed compressor in August isn't the first you hear of a problem. Ask us about a simple seasonal plan for your building.

From building owners & managers
Real Bel Air projects across NJ & NY. (Owner to confirm before launch.)
“Bel Air has done the HVAC on every home I've put up for the last four years. Their bids come back fast, the rough-ins pass inspection, and they're never the trade holding up my schedule. That's worth more to a builder than a low price.”
“We hired Bel Air for the HVAC across a full run of new homes. Same crew, same quality on every unit, and Valera priced the whole project off the plans up front so there were no surprises. We keep calling them back.”
“Our heat died at 5 in the morning in the middle of a cold snap with two little kids in the house. I left a message and got a callback right away — they had us warm again that same day. I won't use anyone else now.”
