A new system here works most of the year
A home in Newark needs heat or cooling 11 months out of the year. Winter nights average 25°F from December through February, and a furnace or heat pump has to hold up through long runs from October through May. Summer afternoons average 84°F, so the same system needs to carry a full three months of cooling, June through August.
Most homes here heat with gas, and any new furnace has to meet the federal efficiency minimum. Power is worth asking about too. Across New Jersey, 11 percent of households went at least 24 hours without power in 2024, and the area has seen 61 damaging wind events and 36 winter storms over the last ten years. When you're choosing a new system, ask a contractor how it comes back on after an outage, and what that means for getting heat back.

New Jersey requires HVAC contractors to hold a state license.
The state board tests contractors before it licenses them and keeps a record of who holds one. That license belongs to the contractor, not to any single job, and it stays the same no matter which town in Essex County the work is in, since New Jersey does not let cities or towns layer on their own HVAC license.
For a heating and cooling installation, the license tells you the contractor was tested and is on record with the state. It does not stand in for the local building office. In most cities and counties, a job like this needs a permit from that office, and an inspector checks the finished installation before it is signed off.

- When should I replace my HVAC system?
- Replace it when repairs stop making sense or the system can't keep up anymore. Watch for signs like frequent breakdowns, a furnace or air conditioner that runs constantly without keeping the house at temperature, or a system that's aging and still using an old refrigerant. With heat needed here from October through May and cooling through the summer, most homes lean on this equipment eleven months out of the year, so a system that's struggling has little time off to recover. A contractor can look at the specific unit and tell you whether it's worth fixing again or time to move on.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is often the better plan. A furnace and air conditioner installed at the same time are matched to work together, and a mismatched pair can wear unevenly and run less efficiently. It also means one visit instead of two if the second unit fails a year or two after the first. If one system is still fairly new, a contractor can tell you whether it makes sense to pair it with the new unit or replace it later on its own.
- What happens during an HVAC installation?
- A contractor removes the old furnace or air conditioner, sets the new equipment in place, and connects it to the existing ductwork, gas line or refrigerant lines, and electrical circuit. Once it's connected, they test it, check airflow and temperature, and make sure it's running the way it should before they leave. In most cities and counties, this work needs a permit from the local building office and an inspection when it's done. New Jersey also requires the contractor doing the work to hold a state HVAC license, so it's worth confirming that before the job starts.
