The most common culprits

Common reasons an AC stops cooling

More than half the "AC not cooling" calls we run come down to a handful of culprits: a failed run capacitor, a dirty or iced-over coil, a clogged filter starving airflow, low refrigerant from a slow leak, or a tripped contactor. Most are same-visit fixes.

If your system is well into its teens and leaking refrigerant, we'll be honest that the smarter money is on a replacement rather than chasing leaks season after season. No pressure either way.

What homeowners 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.”
George Builder, Monmouth County
“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.”
Solo Builders Developer, NJ
“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.”
Danielle R. Homeowner, Howell
