How To Choose A HVAC Company In New Brunswick

Are they licensed in New Jersey?

New Jersey licenses master HVACR contractors through a state board. Ask for the license number and proof of insurance, and confirm the license with the Division of Consumer Affairs.

Do they offer a maintenance plan?

A fall heating check and a spring cooling check catch most problems early. Ask what a plan includes and whether members get priority scheduling in busy weeks.

Can they help with rebates?

Ask whether the contractor works with New Jersey utility and state energy efficiency programs, which can lower the cost of a high-efficiency system or heat pump.

Are their technicians certified?

Look for EPA Section 608 certification, which is required to handle refrigerant, and NATE certification, which shows tested knowledge of installs and repairs.

Do they size the system properly?

Before quoting a new furnace, heat pump or air conditioner, a good contractor will run a load calculation on your Summit home instead of matching the size of the old unit.

Conclusion

Start with MacKinney Oil Heating & Cooling or E & S Heating and Cooling if you want someone close by, and keep Always Comfy in mind for repairs, tune-ups and full system replacements. Two or three written quotes will tell you more than any single phone call.
