Furnace Installation in Concord, NH
Natural Gas Furnaces
Two-stage, modulating, and variable-speed gas furnaces can improve comfort and efficiency compared with older single-stage equipment. We size the furnace and review the venting and ductwork before installation.
Oil Furnaces
Modern oil furnaces provide dependable heat for homes that use heating oil. We match the equipment to the home's heat loss and make sure the burner, venting, and airflow are set up correctly.
Propane Furnaces
Propane furnaces provide strong winter heating where natural gas is not available. We install approved equipment and conversion components for the selected fuel.
High-Efficiency Options
High-efficiency furnaces can reduce fuel use compared with older equipment. We compare efficiency, comfort features, venting requirements, and installed cost. We review any current incentives for qualifying equipment before you decide.
Even Heat Starts With Correct Furnace Sizing
An oversized furnace may warm the thermostat quickly while leaving other rooms uncomfortable. It can also cycle more often and place unnecessary wear on components. We evaluate the home's heat loss, review the existing fuel and venting, and inspect supply and return airflow before selecting a furnace. When a project calls for a detailed heating-load calculation, we can use the Manual J method to confirm the required capacity. If the ductwork has obvious restrictions or leakage, we include the necessary corrections in the plan. You receive an installation designed for reliable Concord winters and serviceable for the years ahead.

Furnace Installation FAQ
How much does a new furnace cost in Concord?
A mid-efficiency gas furnace installation typically runs $3,875-$7,900. High-efficiency 95%+ AFUE variable-speed installations run $5,200-$8,100 depending on size and ductwork condition. Oil furnaces fall 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 changes, and potential chimney work.
What size furnace do I need?
The right furnace size depends on the home's heat loss, not square footage alone. Insulation, windows, air leakage, layout, and outdoor design temperature all matter. We evaluate the home's heating needs before recommending equipment and complete a detailed load calculation when the project requires one. Every new-construction heating and cooling system receives a detailed load calculation.
Is high-efficiency worth the extra cost?
It depends on the existing furnace, fuel use, venting, installation cost, and how long you expect to remain in the home. Higher-efficiency equipment can reduce fuel use and may provide quieter, more even comfort. We compare the installed options instead of promising a fixed payback period.
