New-construction HVAC bids for Marlboro builders
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.
- Load calculations and system design from your architectural plans
- Ductwork, line sets and rough-ins coordinated with your framing schedule
- Furnaces, air handlers, condensers and heat pumps — sized to the home, not guessed
- Multi-unit and repeatable plans for developments and 55+ communities

What our customers say
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.”
