Morristown asks a lot of a new system
Winter nights here run 22°F on average from December through February, and homes need heat from October through May. That's 8 months of the furnace carrying the house through real cold, not just taking the edge off. Summer adds three more months of afternoons averaging 82°F, so the same system covers both ends of the year with little rest between them.
Most homes here heat with gas, so a furnace and air conditioner sized to the house and matched to each other is what gets through 11 months of heating or cooling without either one falling behind.

New Jersey requires HVAC contractors to hold a state license.
New Jersey licenses HVAC contractors through the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration (HVACR) Contractors. That license is held by the contractor, not issued per job, and it comes from the state board, not from Morris County or any town in it. New Jersey does not let cities or towns add their own HVAC license on top, so the license that matters here is the same one that would matter anywhere else in the state.
For a heating and cooling installation, that license is what stands behind the person doing the work. In most cities and counties, putting in a new furnace or air conditioner also needs a permit from the local building office, with an inspection once the work is done. The permit and inspection are separate from the license. One tells you the contractor is on the state's books. The other tells you the installation itself was checked once it was in place.

- When should I replace my HVAC system?
- Most systems tell you before they quit. Watch for repairs that keep coming back, a furnace or air conditioner that can't keep the house at temperature, or a unit that's old enough that parts are getting harder to find. Age matters here, since a furnace runs from October through May and an air conditioner has to hold up through summer afternoons that average 82 degrees. When repair calls start piling up during those stretches, replacement usually makes more sense than another patch job. A contractor can look at the specific unit and tell you whether it's worth fixing again.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, and it matters more here than in places with an easier climate. Homes in this area need heat or cooling 11 months out of the year, so there's almost no stretch where one system can sit idle while you save up for the other. A furnace and air conditioner installed years apart also wear out on different schedules, which can mean paying for two installation visits instead of one. Replacing them together lets a contractor size both for the house as a matched set. If one unit is much newer than the other, there's no reason to replace it early just to match.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, or heat pump, and sets the new equipment in place, then connects it to the ducts, the electrical, the gas line if there is one, and the condensate drain. Refrigerant lines get connected and the system is tested to make sure it's heating and cooling correctly before the job is called done. In most cities and counties this work needs a permit from the local building office, and an inspector checks the finished installation. Any HVAC contractor doing this work in New Jersey has to hold a state license through the Board of Examiners, since the state doesn't allow cities or towns to require a separate local license.
