HVAC Contractor Totowa
The first real heat wave every summer sounds the same around here. The air is running, but the house is not getting cold. Come January it flips. A furnace that worked fine in November clicks, blows cold, and quits on the coldest night of the year. Plenty of homes in North Jersey still run equipment that has sat in the basement for fifteen or twenty years, so a rough season shows up fast.
On Site Plumbing, Heating & Cooling is the HVAC contractor Totowa families call when that happens. The company has served North Jersey since 2024 and is licensed and insured for both plumbing and HVAC, which helps on jobs where a gas line, a condensate drain and a heating system all touch each other. Someone answers the phone at any hour, day or night, and a truck is usually at the curb within the hour.
Heating and cooling work in North Jersey is its own animal. Humid, sticky Augusts push air conditioners hard, and wet snow followed by a deep freeze does the same to furnaces. Good HVAC service starts with finding the real cause instead of swapping the first part that looks tired. Below is every heating and cooling job we take, each with a page of its own.

Air conditioning installation
A new air conditioner goes in when the old one leaks refrigerant every season, runs constantly without cooling, or finally dies in the middle of August. We measure the house rather than matching whatever was there before, because an oversized unit cools fast, shuts off, and leaves the air damp and clammy. Line sets, the condensate drain and the electrical all get done right the first time. See our air conditioning installation page for sizing, timelines and what a clean install looks like.
Air conditioning repair
Warm air from the vents, ice on the copper line, a loud hum with no cold, or a unit tripping the breaker fills our summer schedule. Usually the cause is a dirty coil, a low charge from a slow leak, a failed capacitor, or a plugged condensate line pushing water into the pan. We test the whole system before touching a part, then explain what failed in plain words. Our air conditioning repair page covers the usual causes and how fast we can get to you.
Furnace installation
Furnace installs happen for a reason: the old unit cracked, the repair bills stopped making sense, or an addition left half the house cold. We size the new furnace to your rooms, check that the ductwork can actually carry the air, and set the venting and gas connection to code. Older basements around Totowa often need the flue reworked, and that comes with the job. Read the furnace installation page for what a swap involves and how long it takes.
Furnace repair
A furnace usually warns you first. It short cycles, rattles, smells like burning dust too long, or the burners light then drop out after a minute. The common culprits are a dirty flame sensor, a cracked igniter, a filter so clogged the blower starves, or a motor on the way out. We check gas pressure, venting and every safety, because a furnace that runs is not the same as one that runs safely. Read the furnace repair page for what a no heat call looks like.
Heating system repair
Not every house here heats with a furnace. Plenty run boilers, radiators, baseboard loops or heat pumps, and each one fails in its own way. Cold rooms upstairs, banging pipes, a system that never shuts off, or a thermostat calling for heat with nothing happening all point somewhere different. We track the fault through the controls, the circulator and the zone valves instead of guessing. See our heating system repair page for the problems we see most in January.
HVAC maintenance
Most breakdowns we get called for were avoidable. A spring tune-up on the air conditioner and a fall check on the heat catch the weak capacitor, the dirty flame sensor, and the coil packed with cottonwood fluff before a holiday weekend does. We clean, test the electrical, check refrigerant levels and gas pressure, and tell you what is aging. Twice a year keeps the equipment quieter and the bills lower. Our HVAC maintenance page explains what each visit includes.
Thermostat installation
A smart thermostat pays for itself in a North Jersey winter, but only if it is wired to your system correctly. Multi-stage furnaces, heat pumps and zoned setups all need the right wiring, and many older Totowa homes have no C-wire at the wall. We handle that, mount the new stat where it reads real room temperature, and set the schedule with you before leaving. See the thermostat installation page for models that work with your equipment.
Air duct cleaning
Dust blowing out of the vents, rooms that never balance, or allergies flaring the day the heat kicks on often trace back to the ducts. Decades of dust, drywall grit from an old remodel, and pet hair collect in there and ride the airflow into every room. We clean the trunk lines and branches, seal the obvious leaks we find, and put in a fresh filter. Read the air duct cleaning page for what the process looks like.
