Heating
Furnace Installation & Swap-Outs
Reliable warm-air heat, installed clean and sized right.
Quick answer
What a furnace swap-out costs depends on the size of the home, the efficiency you choose, and the venting the job needs. A furnace that dies in a January cold snap is a no-heat emergency at the worst possible price, so replacing a tired system before it picks the date for you is the smart move. So I check your setup, size the new furnace with a real load calculation, and put your exact number in writing for free. I install and size warm-air furnaces myself, so the heat is even, the burner is safe, and the work stays clean.

What you get
Right-sized warm-air heat
I size the furnace to your home with a real load calculation, so it is not oversized to short-cycle or undersized to run cold.
A safe, clean burner and venting
I set the gas, the venting, and the combustion air correctly, and I test the system before I leave. Safe heat is the whole point.
High-efficiency options that earn rebates
A modern furnace with an ECM blower can qualify for NHSaves money and uses less power moving your air.
A clean install that lasts
Tight duct connections, a level set, sealed joints. The kind of work that runs quiet for years and does not call me back.
Who it's for
Your furnace is 15 years or older and you would rather replace it on your terms than in an emergency.
You have an aging oil system and want to move to clean, efficient gas heat.
Your current furnace short-cycles, heats unevenly, or costs too much to run.
You want a straightforward, reliable heating system and a straight answer on the price.

Real cost and rebates
Quick answer
An exact written number, free, before any work starts
What a gas furnace swap-out costs depends on the size, the efficiency, the venting, and any ductwork the job needs, and that spread is real money. In New Hampshire, NHSaves pays roughly $300 to $450 on a qualifying high-efficiency furnace with an ECM blower. The federal 25C tax credit ended on December 31, 2025, so ignore any site still promoting it. I size your system, put the real number in writing for free, and tell you honestly what it qualifies for.

What people are saying
EXAMPLE. Sample content shown for the demo, replaced with real customer reviews at launch.
Our furnace was on its last legs and Tanner swapped it before winter hit. One day, clean work, and he showed me exactly how it runs. Honest price, no games.
He replaced an ancient system and the house heats even now, no more cold rooms. Tanner did it himself and answered every question. I would call him again.
Common questions
How much does it cost to replace a furnace in NH?
It depends on the size of the home, the efficiency you choose, and any duct or venting work the job needs, and that spread is real money. So I measure your home, size the furnace with a real load calculation, and put your exact number in writing for free, with the NHSaves rebate already counted.
How long does a furnace swap-out take?
Most straightforward swaps are a one-day job. I pull the old unit, set and connect the new one, and test it the same day so you are not left without heat.
Should I repair my old furnace or replace it?
If it is under about 12 years old and the repair is small, fixing it can make sense. Once a furnace is 15-plus years old, short-cycling, or needs an expensive part, replacing it before it fails in a cold snap usually costs less in the long run. I give you the honest math, not a scare tactic.
Do you install heat pumps instead of furnaces too?
I do. A lot of homeowners pair a heat pump for efficient heating and cooling with a furnace as cold-snap backup. I lay out both paths and the real numbers so you can choose.
