Most HVAC companies in New Jersey close at 5 p.m. and send after-hours calls to voicemail. We built Heating Cooling NJ around the opposite idea: that the moment your heat or air conditioning fails is exactly when you need a real person and a real technician. Our phone line is staffed 24 hours a day, every day of the year, and the price you are quoted at midnight is the same price you would pay at noon.
Every technician is EPA-certified to handle refrigerant, background-checked and trained on both modern inverter equipment and the 25-year-old boilers still heating thousands of New Jersey homes. We diagnose with instruments, not guesses, and we give you a written flat-rate price before any work starts. When a repair no longer makes financial sense, we tell you, show you the numbers and let you decide.
From our headquarters at 544 Ringwood Ave in Wanaque, our North Jersey team covers Passaic, Bergen, Morris, Essex, Hudson, Union, Sussex and Warren Counties, while our Central and South Jersey teams serve Middlesex, Somerset, Hunterdon, Mercer, Monmouth, Ocean, Burlington, Camden, Gloucester, Salem, Cumberland, Atlantic and Cape May. Wherever you are in the state, help is a phone call away.
A furnace that fails at 2 a.m. in January is a safety problem, not an inconvenience. Pipes freeze, families get sick and older homes can suffer serious damage within hours. Our 24/7 emergency HVAC service exists for exactly these moments. Call, describe what the system is doing, and a dispatcher gives you an honest arrival window while the nearest available technician loads the parts your system is likely to need.
Summer emergencies are just as real. New Jersey heat waves push 15-year-old air conditioners past their limits, and a home with no cooling is dangerous for infants, seniors and anyone with a medical condition. We prioritize those households and carry capacitors, contactors, motors and refrigerant so most AC repairs are finished on the first visit.
Emergency calls we handle every week include no heat from gas, propane and oil furnaces, boilers that have lost pressure or stopped firing, heat pumps iced over or stuck in defrost, air conditioners blowing warm air, water leaking from air handlers and boilers, gas and burning odors, and carbon monoxide alarms. If you smell gas or a CO detector sounds, leave the home and call 911 first; we will handle the repair once the house is safe.
