Our flagship — what we do best
New construction is what we do best. For builders and developers across New Jersey and New York, we size, lay out and install complete heating and cooling systems — from a single custom home to a full development of look-alikes.
We read off your plans, hold a price you can put in a contract, and keep our rough-ins on schedule so we're never the trade holding up your drywall. We've run HVAC for everything from large lakefront custom homes to a 21-unit apartment building in Long Branch.

What we do
Old system on its last legs? We right-size and install high-efficiency AC, furnaces and heat pumps — and haul the old one away.
No heat, a noisy furnace, or a system that can't keep up? We repair, tune up and install gas furnaces, air handlers and heat pumps.
AC not cooling, freezing up, or running but not keeping up? We diagnose and repair central air, and tune it up before summer.
Strip malls, plazas, apartment buildings and build-outs. Rooftop units, replacements and new tenant fit-outs.
We also handle equipment sales as part of our installs, and offer fall/spring tune-ups. Financing available.
Real jobs, real towns
A family in Howell woke to a dead furnace on one of the coldest mornings of the winter — two young kids and a house dropping into the 50s. They called first thing; our tech was out the same morning, found a failed ignitor, and had heat back on before lunch. No drama, no upsell.
When a 21-unit apartment building near the Long Branch shore needed its heating and cooling done right, we designed and installed the whole system — unit by unit, on schedule, coordinated around the other trades. The kind of small-commercial project we're built for.
Big custom homes need carefully zoned systems so the far bedroom is as comfortable as the great room. We've designed and installed multi-zone HVAC for large lakefront and estate properties in Colts Neck and the surrounding towns — quiet, even, and built to last.
Trusted since 1998
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.”
“They put the entire HVAC system into our 21-unit building in Long Branch. Organized, on schedule, and they actually answered the phone the whole way through. Finding a contractor who handles a building that size and still treats you like a person is rare.”

FAQ
No fine print. If you don't see your question here, just call or send a note — we answer honestly, including when the right answer is "you don't need that."
For most New Jersey homes, a full central-air replacement runs roughly $7,000–$13,000 depending on the size of the home, the efficiency of the equipment, and whether ductwork or a furnace are part of the job. A high-efficiency or heat-pump system sits at the upper end but can qualify for rebates. We give a firm written estimate after we measure the home — no guessing off the phone.
