Frequently asked questions

What should I do if I have no heat?

Check that the thermostat is set to heat and the system switch and breaker are on. If it still won't run, call 908-235-2728 to get on the schedule.

Can you work on old steam boilers?

Yes. Many homes in Somerset and Hunterdon Counties still have steam heat. We service, repair and replace steam boilers and can recommend whether an overhaul or a replacement makes more sense.

How often should a furnace or boiler be serviced?

Once a year, before the heating season starts. A tune-up improves efficiency and lets us catch safety issues like cracked heat exchangers or venting problems early.
