Get the equipment model numbers on every quote.

Before you sign anything

  1. Ask for the Master HVACR license number. New Jersey has licensed this trade since 2008, and the number belongs on their paperwork.
  2. For replacements, get a written proposal with the exact equipment model numbers, not just the brand and tonnage. Substitutions happen when it's vague.
  3. Ask whether they pull the permit or you do. Equipment replacement generally needs one, and a contractor who suggests skipping it is telling you something.
  4. If you heat with oil, ask specifically about oil-to-gas conversion experience and who runs the gas line. Dual-licensed shops (HVACR plus plumbing) handle it in-house.
  5. A maintenance plan is fine; a maintenance plan sold at the door with a same-day discount is not.

Heating and cooling contractors hold a Master HVACR license from the state board, checkable at newjersey.mylicense.com.

The local picture

One of the strongest local trades here: several genuine owner-operated shops with real review bases, and the private-equity rollups that swallowed the Route 1 corridor have not reached this county yet.

Questions neighbors actually ask

Is my HVAC contractor required to be licensed in New Jersey?

Yes. New Jersey licenses Master HVACR contractors through a state board, and the license number should appear on contracts and advertising. You can verify it at newjersey.mylicense.com. This is a real license with exam requirements, unlike the registration home improvement contractors carry.

Should I convert from oil to gas?

It depends on whether gas runs down your road, and a lot of Hunterdon roads still don't have it. Where gas is available, conversions are this county's signature HVAC job because of the old oil-heated housing stock. Get quotes from a dual-licensed shop that can run the gas line and handle the tank question in one project.

What does a heat pump cost versus a new furnace?

It varies too much by house to give one honest number, but two things are reliably true here: NJ Clean Energy program incentives change the math year to year, and any quote should show you the equipment model numbers so you can compare like against like. Get three quotes and make them itemize.
