The typical furnace replacement cost Michigan homeowners pay in 2026 is about $3,000 to $9,500 for an installed gas furnace, according to HVAC Project Cost. Replacing the furnace and central air conditioner together runs about $5,200 to $14,500 from the same source, and your exact price comes from an in-home estimate.
This guide explains what moves the furnace replacement cost Michigan price up or down and how homeowners around Big Rapids, Reed City, and the rest of West Michigan can plan the project without surprises.
Fullmer & Sons Heating, Cooling & Fireplaces has been installing and servicing furnaces from our Big Rapids location since 1971. We are a family business, and we have seen almost every kind of home, from farmhouses outside Evart to lake homes in Canadian Lakes. Here is what we want every homeowner to know before getting quotes.
Average Furnace Replacement Cost Michigan (2026)
Published cost data gives a useful starting point. HVAC Project Cost reports a range of $3,000 to $9,500 for a gas furnace replacement in Michigan, and $5,200 to $14,500 when the furnace and central air conditioner are replaced together.
Those are statewide furnace replacement cost Michigan figures, not our prices. Every home is different, so the only number that matters is the one from an in-home estimate. Still, the ranges help you tell whether a quote is reasonable.
- Gas furnace replacement: $3,000 – $9,500 (HVAC Project Cost, 2026)
- Gas furnace + central AC: $5,200 – $14,500 (HVAC Project Cost, 2026)
What Changes the Price of a New Furnace
Two homes on the same road can get very different furnace replacement cost Michigan quotes. These are the factors that make the biggest difference.
Efficiency (AFUE rating)
AFUE tells you how much of your fuel becomes heat in your home. A 97% AFUE furnace turns 97 cents of every fuel dollar into heat. Higher efficiency costs more up front but lowers your bills every winter, and Michigan winters are long. ENERGY STAR explains how certified furnaces save energy.
The Carrier furnaces we install include the Performance 97 (59TP7), the Infinity 97 (59TN7), and the Infinity 98 with Greenspeed intelligence (59MN7).
Size of the furnace
Bigger is not better. An oversized furnace cycles on and off too often, wears out faster, and leaves hot and cold spots. An undersized one runs nonstop on the coldest nights. A proper sizing check during the estimate protects you from both problems.
Natural gas or propane
Many rural and small-town homeowners in our area heat with propane, while others are on natural gas. Your fuel type affects which furnace and setup fits your home, so we confirm it during the estimate.
Ductwork, venting, and the old unit
High-efficiency furnaces vent differently than older models. Some homes need venting changes, duct repairs, or a new thermostat. Removing and disposing of the old furnace is also part of the job. A good quote lists all of this, so you are comparing complete prices.
Controls and thermostats
A new furnace is a good time to upgrade your thermostat. We offer the ecobee for Carrier smart thermostat and the Carrier Infinity System Control. See our controls page for options.
Repair or Replace? How Age Affects Furnace Replacement Cost Michigan Homes Face
Not every problem means a new furnace. Here is a simple way to think about it.
- Repair makes sense when the furnace is fairly young, the fix is minor, and the system has been reliable.
- Replace makes sense when repairs keep coming back, bills keep rising, rooms heat unevenly, or a major part such as the heat exchanger fails.
- Age matters. Our earlier post explains why upgrading an 8+ year-old HVAC system can be a smart investment.
If you are not sure, ask for an honest assessment. We would rather tell you a repair is enough than sell you equipment you do not need.
Carrier Performance vs. Infinity: Which Fits Your Home?
Because we install Carrier furnaces, we can keep your furnace replacement cost Michigan quote in line with your budget and comfort goals.
- Carrier Performance: reliable comfort at a sensible price, with high efficiency and a proven design.
- Carrier Infinity: maximum comfort and efficiency, with Greenspeed intelligence on the Infinity 98, which reaches up to 98.5% AFUE.
Many homeowners also pair a new furnace with a heat pump for a Hybrid Heat setup. Our heat pump page covers the equipment.
When Is the Best Time to Replace a Furnace?
The worst time is a January night when the furnace stops working. Emergency replacements leave no time to compare options. Planning ahead in spring, summer, or early fall gives you time to choose the right furnace and schedule the install when it suits you.
Watch for warning signs: strange noises, a yellow burner flame, frequent cycling, rising bills, or rooms that never feel warm. Any of these is a good reason to call before winter.

Questions to Ask Before You Sign a Furnace Quote
Comparing quotes is smart, but only if you compare the same things. Before you decide, ask each contractor these questions.
- Did you do a sizing check? A quote based only on the size of the old furnace can repeat an old mistake.
- What exactly is included? Ask about venting, duct repairs, the thermostat, permits, and removal of the old unit.
- What is the AFUE rating and model number? This lets you compare equipment side by side.
- What warranty comes with the furnace and the labor? Get it in writing.
- Who services it afterward? A local company you can call matters when something needs attention in the middle of winter.
A low price that leaves out venting or ductwork can end up costing more. A clear, itemized quote is the best way to compare the furnace replacement cost Michigan contractors quote you.
How to Make Your New Furnace Last
A new furnace is built to last many years, and a little care helps it get there.
Change the filter on schedule
A clogged filter makes the furnace work harder and can shorten its life. Check it every month or two during the heating season.
Book yearly maintenance
A tune-up before winter lets a technician clean parts, check safety controls, and catch small problems early. It is far cheaper than an emergency call on the coldest night of the year.
Keep vents and the area around the furnace clear
Blocked supply and return vents restrict airflow. Keep storage away from the furnace and make sure outdoor vent pipes stay clear of snow and ice.
If you heat with propane or natural gas, a working carbon monoxide detector is also a must. Ask us during your visit if you are unsure where to place one.
