Furnace Installation & Repair in Maine & New Hampshire

Quick answer: Local Energy, LLC repairs, tunes up and replaces natural gas, propane and oil furnaces for homes and businesses across Maine and New Hampshire. Every replacement is sized with a Manual J heat loss calculation, and we can pair a furnace with a central heat pump for efficient heating and cooling.

A forced-air furnace heats your home by blowing warm air through ductwork. When a furnace stops heating, short-cycles, gets noisy, or your fuel use keeps climbing, we’ll find the cause and give you a straight answer on whether to repair it or replace it.

Repair or Replace?

A furnace may be nearing the end of its life if repairs are getting more frequent or more expensive, rooms take longer to heat, or your fuel use has climbed without a clear reason. We’ll walk you through both options and never default to the more expensive one.

Why Sizing Matters

An oversized furnace short-cycles, which wastes fuel, wears out parts and leaves rooms uneven. We run a Manual J heat loss calculation before recommending any new equipment. Read why a Manual J calculation matters.

Adding a Heat Pump to Your Ductwork

If your home already has ductwork in good shape, a central heat pump can provide efficient heating and air conditioning, with your furnace as backup on the coldest nights. Efficiency Maine rebates can help with the cost. See Ductless vs. Central Heat Pump.

Frequently Asked Questions

Do you repair all furnace brands?

We service natural gas, propane and oil furnaces. Call us with your furnace’s brand and age and we’ll let you know.

How often should a furnace be serviced?

Once a year, before heating season. A tune-up catches small problems before they become a no-heat call and helps keep manufacturer warranties valid.

Can I switch my oil furnace to gas or propane?

Yes. We handle oil-to-gas conversions, including equipment, gas piping and propane tank setup. See our Oil to Gas Conversion page.

What should I do if my furnace stops working in winter?

If you smell gas or a carbon monoxide alarm is sounding, get everyone outside and call 911 first. Otherwise, call our emergency line. See Emergency Heating Service.
