FAQ
Straight answers to common HVAC questions
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."
How much does AC replacement cost in NJ?
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.
Do you do HVAC for new construction?
Yes — new construction is our specialty. We design and install complete heating and cooling systems for new homes, developments, additions and light-commercial build-outs across New Jersey and New York. Send us your plans and we'll get you a firm bid you can put in a contract, usually within a few days.
What brands do you install?
We're an authorized dealer for Rheem, Ruud and Goodman, and we install and service all other major brands as well — Trane, Lennox, Carrier and more. We'll recommend the right equipment for your home and budget rather than pushing one label.
What areas do you serve?
All of New Jersey and New York. We're based in Monmouth County and regularly work towns like Marlboro, Manalapan, Freehold, Howell, Colts Neck, Holmdel, Middletown, Long Branch, Old Bridge and Edison, plus Brooklyn and Staten Island in New York. We'll also work near the Pennsylvania line for large developments.
Are you licensed and insured?
Yes. Bel Air Systems holds a New Jersey Master HVAC License plus Master HVAC Refrigeration, and we're fully insured. We're a family-owned contractor serving NJ and NY since 1998.
Do you offer 24/7 emergency service?
We return calls quickly and aim to get out for no-heat and no-cool calls the same or next day. Honest and reliable beats a promise we can't keep.
