How To Choose A HVAC Company In Union

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.

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 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.

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.

Conclusion

Max Sr. & Paul Schoenwalder, Chapman Bros. Plumbing, Heating and Air Conditioning and One Call Electrical, Heating & Cooling give Union homeowners a solid shortlist for repairs, tune-ups and full system replacements. Compare written quotes, check credentials and ask how soon each can come out.
