North Plainfield asks a lot from a system, most of the year
A heating and cooling system here works eleven months of the year. Heat runs October through May, with winter nights averaging 24°F from December through February. Cooling takes over in June and holds through August, with afternoons averaging 84°F. There is almost no season where the system sits idle.
Most homes here heat with gas, and any new furnace has to meet the federal minimum efficiency rating. Power is worth planning around too. Statewide, 11% of households went at least 24 hours without power in 2024, and this area has logged 21 winter storms and 153 damaging wind events over the past ten years. A new system needs to handle the cold and the heat, and hold up through what the weather here brings.

New Jersey requires HVAC contractors to hold a state license.
The state board tests contractors before they issue this license, and it covers the contractor, not any single job. Somerset County towns cannot add their own HVAC license on top of it, so the state credential is what applies wherever you are in the county.
For a heating and cooling installation, that license is what stands behind the person doing the work. In most cities and counties, a job like this also needs a permit from the local building office, with an inspection once the work is done.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is breaking down more than once a season, or a contractor tells you the heat exchanger or the compressor is failing, it is time to replace it rather than repair it again. Age matters too. An older furnace or AC that needs a costly repair usually isn't worth fixing. Homes here run the heat from October through May, so a furnace that quits in the middle of that stretch is not something you want to gamble on.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it makes sense to replace them together. They share the same blower and duct system, and a furnace and AC installed at different times often don't match well in efficiency or airflow. That said, if your AC just failed and your furnace is only a few years old, there is no reason to replace a furnace that still has years left in it. A contractor can look at both and tell you what actually needs doing.
- What happens during an HVAC installation?
- A contractor removes the old furnace or air conditioner, sets the new equipment, and connects it to your existing ducts, gas line or refrigerant lines and electrical. They test the system, check refrigerant charge and airflow, and walk through the thermostat with you before leaving. Because this involves gas or refrigerant lines and electrical work, most towns require a permit from the local building office and an inspection once the job is done. New Jersey licenses HVAC contractors through the state, not the town, so any licensed contractor can pull that permit here.
