Furnace replacement and installation in Grand Rapids
A new gas furnace sized to your house, vented correctly and started up with combustion readings, not just swapped in at the same size as the old one.
The short answer
Furnace replacement in Grand Rapids starts with a load calculation, then a choice of efficiency, staging and venting. Michigan gas furnace replacement typically runs $3,000 to $9,500 installed according to 2026 statewide data. We handle the permit, remove the old furnace, install and vent the new one, and start it up with combustion readings.
Replace it right
What goes into a furnace replacement
The furnace is the heart of a Grand Rapids house for half the year. The replacement decision comes down to efficiency, how evenly you want the house heated, whether the venting can stay as it is, and what the air conditioner on top of it needs.
If your AC is also aging, replacing both together saves labor and matches the equipment; see AC replacement work. For a heat pump alongside the new furnace, see dual-fuel systems in Grand Rapids.
Pricing, explained
What a furnace replacement costs
Michigan gas furnace replacement runs $3,000 to $9,500 installed according to 2026 statewide pricing, and replacing the furnace and AC together runs $5,200 to $14,500. These factors decide where your job falls.
Efficiency
80 percent units cost less than 96 percent condensing models.
Staging and blower
Single-stage, two-stage and modulating differ in price.
Venting
PVC venting, liners and chimney corrections.
Size
Sized by load calculation, not by the old nameplate.
Paired equipment
Replacing the AC coil or whole AC at the same time.
Choosing between options
Single-stage, two-stage or modulating
Comfort and efficiency rise with each step, and so does the price.
| Single-stage | Two-stage | Modulating | |
|---|---|---|---|
| How it heats | Full fire every cycle | Low most days, high on cold days | Small steps to match load |
| Evenness | Basic | Better | Best |
| Noise | Loudest | Quieter | Quietest |
| Relative cost | Lowest | Middle | Highest |
The four decisions we walk through
80% to 96% AFUE upgrades
AFUE is the share of the gas that becomes heat in the house. An 80 percent furnace vents hot exhaust through a metal flue or chimney; a 96 percent furnace condenses its exhaust, vents through PVC and needs a condensate drain. In a Michigan winter the higher-efficiency furnace saves noticeably on gas, and Consumers Energy has offered a small rebate on qualifying 95 percent AFUE models. The 80 percent option still has a place where venting a high-efficiency unit is impractical.
Two-stage and modulating furnaces
A single-stage furnace runs at full fire every time. A two-stage furnace runs at a low fire most of the winter and switches to high only on the coldest days, which means longer, quieter cycles and more even temperatures between rooms. A modulating furnace adjusts in small steps and holds temperature most closely of all. Paired with a variable-speed blower, both help an air conditioner remove humidity in summer. The cost rises with each step, so we match the choice to what bothers you about the current system.
New-construction furnace installation
In a new house or a major addition, the furnace, ductwork and venting are designed together from the start. We size the furnace from a load calculation on the plans, coordinate the flue or PVC vent route with the framing, and set up gas and electrical connections with the other trades. Starting right avoids the most common new-construction complaint, which is an oversized furnace that short cycles, runs noisy and heats upstairs and downstairs unevenly. We also plan the return air paths so bedrooms with closed doors still get airflow.
Chimney-vented to direct-vent conversion
Replacing an old chimney-vented furnace with a high-efficiency model removes it from the chimney and vents it through PVC out a side wall. If a gas water heater still uses that chimney, it is now alone in a flue sized for two appliances, which can cause poor draft and condensation. We check and correct that at the same time, usually with a liner sized for the water heater, so the replacement does not create a new problem in the basement that nobody notices until the water heater starts backdrafting.
What the visit covers
What every furnace replacement includes
- Load calculation for sizing

Pricing and home values in Grand Rapids
Statewide 2026 pricing data puts Detroit-area furnace installs 10 to 20 percent above the Michigan average, while Grand Rapids work tends to land closer to the statewide ranges on this page. With a median home value around $225,500, most owners here are choosing between solid mid-range equipment options rather than top-tier systems, so we price at least two choices on every replacement.
