Our Air Conditioning Services

AC Repair

Blowing warm air, freezing up, short cycling, or not turning on at all? We find the fault — refrigerant, electrical, airflow, or controls — and fix it right the first time.

AC Installation & Replacement

A properly sized system is the difference between a cool home and a cool-ish home with a big electric bill. We size installations to your house, not a rule of thumb, and install for efficiency and longevity.

AC Tune-Up & Seasonal Maintenance

A spring AC tune-up — cleaning coils, checking refrigerant, inspecting electrical components — keeps your system at peak performance and catches small problems before they become July emergencies. Regular AC maintenance is the cheapest insurance your cooling system can have.

Heat Pump Cooling

Heat pumps cool as well as heat, and we service both sides of the system. See our heating page for heat pump details.

Emergency AC Service

AC quits on the hottest night of the year? We offer emergency AC service 24 hours a day — call (908) 346-7473 and talk to a local technician, not a call center.

Indoor Air Quality

Cool air that's also clean air: whole-home purification, filtration, and humidity control that work through your existing system. See our indoor air quality services — including air purifiers and humidifiers & dehumidifiers.

Is It Time to Replace Your AC?

System is 12–15 years old or older
Repairs are becoming frequent and expensive
Electric bills rise every summer while comfort falls
Some rooms never get as cool as others
The system uses R-22 refrigerant (phased out — repairs get pricier every year)

A modern high-efficiency system can noticeably cut cooling costs while cooling more evenly. We'll compare the real numbers — repair cost vs. replacement savings — and let you decide. And in the off-season, our heating team keeps the other half of your comfort system in shape.
