Furnace Installation in Manchester, NH
Natural Gas Furnaces
Modulating 95%+ AFUE gas furnaces from Lennox, Trane, and Carrier. Two-stage and variable-speed options cut operating costs significantly.
Oil Furnaces
For homes without gas service, modern oil furnaces deliver reliable heat at 85%+ efficiency. Thermo Pride and Williamson are proven workhorses.
Propane Furnaces
Propane furnaces deliver strong heating performance in areas without natural gas. Most gas furnaces convert easily to LP with the right orifices.
High-Efficiency Options
Condensing furnaces with 95-98% AFUE qualify for NHSaves rebates and pay back the upcharge in 3-5 years through lower gas bills.
Sized and Installed Right for Manchester Homes
The biggest mistake we see on furnace installations is oversizing. A furnace that's too big cycles on and off constantly, leaves cold spots in the house, and wears out sooner. For every install in Manchester, we run a Manual J load calculation to match the furnace to your home's actual heat loss. Accounting for insulation, windows, air leakage, and layout. Same attention on the ductwork: we re-evaluate supply and return sizing with the new equipment, fix poorly designed runs from previous installations, and seal duct leaks we find along the way.
- Manual J load calculation on every install
- Duct inspection and sealing as needed
- High-efficiency options with NHSaves rebates
- Financing available with approved credit
- Full workmanship warranty

Furnace Installation FAQ
How much does a new furnace cost in Manchester?
A mid-efficiency gas furnace installation typically runs $4,500-7,000. High-efficiency (95%+ AFUE) variable-speed installations run $6,500-10,000 depending on size and ductwork condition. Oil furnaces are in a similar range.
How long does a furnace installation take?
Most same-fuel replacements are done in one day. Converting from oil to gas (or vice versa) takes 2-3 days because of line runs, venting, and potential chimney work.
What size furnace do I need?
Depends on your home's heat loss. Not square footage. A 1,500 sq ft well-insulated home might need a 60,000 BTU furnace; a 1,500 sq ft drafty older home might need 80,000. We calculate, we don't guess.
Is high-efficiency worth the extra cost?
For most Manchester homes with heavy winter use, yes. You'll recoup the extra cost in reduced gas bills within 3-5 years, with rebates helping close the gap faster. High-efficiency furnaces also tend to be quieter and more comfortable.
