Constant Air Service was founded in 1999 by Jim Reilly, and more than 25 years later it’s still a family-run business rooted right here in Newton, New Jersey.

Jim and his team answer the phone 24/7, show up when they say they will, and stand behind every install and repair.

HVAC problems don’t follow a schedule, and neither do we. Our technicians are available around the clock for emergency repairs.
We value your time. We want to ensure your expectations are met and we start that by making sure the project is right from the first meet.
We take pride in ensuring we are competitive. Find it cheaper? Let's talk.
Newton sits at a higher elevation than most of New Jersey, which means colder, longer winters and real, sustained demand on heating systems. Sussex County’s older housing stock often carries duct and insulation quirks that a regional chain dispatching from an hour away simply doesn’t know to look for. A locally based contractor who knows the towns, the building patterns, and the local permit offices is positioned to size and install your system correctly the first time — and to reach you fast when the heat fails in January or the AC quits in July.
That’s the difference we’ve built our reputation on since 1999: honest assessments, right-sized equipment, licensed work, and a team that actually answers the phone.
