Constant Air Service is a family-owned HVAC company in Newton, serving Sussex County for more than 25 years. We install, repair, and maintain heating, cooling, and geothermal systems — sized for our higher-elevation climate, and backed by the same local technicians your neighbors already trust.
One licensed, family-owned team for every part of your home’s comfort system — install, repair, and maintenance, backed by NJ HVACR license #19HC00108700 and 25+ years in Sussex County.
Gas and oil furnaces, boilers, and heat pumps sized for Sussex County’s long, cold winters — with 24/7 emergency heat when you need it most.
Central air and energy-efficient ductless mini-splits that keep you comfortable through humid North Jersey summers — with same-day emergency service.
Ground-source geothermal that cuts energy costs for the long haul, plus seasonal tune-ups that catch small problems before they become no-heat emergencies.
Four steps to comfort done right the first time — no call centers, no guesswork, no surprises.
Reach our Newton office 24/7. We talk through the problem and book a free, no-pressure in-home estimate.
A licensed tech finds the real issue and sizes any equipment for your actual home — never a generic guess.
We do it right the first time, protect your home, and clean up before we leave.
Your system runs the way it should — and we pick up the phone if you ever need us again.
Newton sits higher and colder than most of New Jersey. A contractor who actually knows our climate — and is 15 minutes away — is the difference between a quick fix and a long, cold wait.
We size every system for Sussex County’s long winters and humid summers — not a generic load calculation that leaves you cold or overspending.

We’re family-owned and still here next season to stand behind the install — no call center, no rotating subcontractors.
