How Much Does a New Furnace Cost in Grand Rapids?

"How much for a new furnace?" It's the first question every homeowner asks, and I get it — nobody budgets for furnace replacement. Your old system dies on a Tuesday night in January, and suddenly you're making a $5,000 decision with frozen pipes and a cold family in the background. I want to take the guesswork out of that, so here are real numbers for what furnace replacement actually costs in the Grand Rapids area in 2026.

These prices come from what we see daily on installs across Jenison, Hudsonville, Grandville, Wyoming, and Grand Rapids proper. They're not national averages pulled from a home improvement website. They're what you'll actually pay a licensed contractor in West Michigan.

Furnace Replacement Cost by System Type

Let's start with the ranges. Every home is different, but here's what most homeowners in our service area are paying right now:

Standard-efficiency gas furnace (80% AFUE): $3,000 to $5,500 installed. This is a single-stage furnace with a basic blower. The equipment itself runs $1,200 to $2,500, with the rest going to labor, permits, and materials. These units vent through a metal flue pipe and chimney, so if your home already has that setup, installation is straightforward.

Mid-efficiency gas furnace (90-92% AFUE): $3,800 to $6,500 installed. A step up in efficiency with a secondary heat exchanger. These require PVC venting through a sidewall rather than a chimney, so if you're upgrading from an 80% unit, there's some extra work involved.

High-efficiency gas furnace (95-98% AFUE): $5,000 to $10,000 installed. This is the sweet spot for most West Michigan homeowners. You're getting a two-stage or modulating burner, a variable-speed blower, and the best fuel efficiency available. The equipment costs more, but your gas bills drop noticeably. The upper end of this range is for top-tier modulating furnaces from brands like Carrier or Lennox with variable-speed ECM motors and advanced controls.

Boiler replacement (hot water/steam): $5,000 to $12,000+ installed. If your home has radiators or baseboard heat, you're looking at a boiler replacement rather than a forced-air furnace. Boilers cost more because the equipment is pricier and installation is more involved. Older homes in Heritage Hill, Eastown, and parts of Grand Rapids often have boiler systems.

Electric furnace: $2,000 to $4,000 installed. Lower upfront cost, but electricity is more expensive than natural gas in Michigan, so your operating costs will be higher. These make sense in a few specific situations, but for most homes with gas service in the Grand Rapids area, a gas furnace is the better long-term value.

What Affects Your Final Price

Those ranges are wide because no two installations are the same. Here's what pushes your price up or down:

Home size and furnace capacity. A 1,200-square-foot ranch in Hudsonville needs a different furnace than a 3,000-square-foot two-story in East Grand Rapids. Furnace capacity is measured in BTUs, and the right size depends on square footage, insulation, window quality, ceiling height, and layout. A properly sized furnace for a typical West Michigan home runs 60,000 to 120,000 BTUs. Bigger isn't always better — an oversized furnace short-cycles and wears out faster. We do a load calculation to get the sizing right.

Ductwork condition. If your existing ductwork is in good shape and properly sized, we connect the new furnace and move on. If the ducts are undersized, leaking at every joint, or crushed in the crawl space, that needs to be addressed. Ductwork modifications can add $500 to $2,500 to the project. Homes built before the 1970s in the Grand Rapids area are the most likely to need duct work.

Efficiency rating (AFUE). The difference between an 80% and a 96% AFUE furnace is real. An 80% unit sends 20 cents of every dollar of gas up the flue pipe as wasted heat. A 96% unit wastes only 4 cents. Over a Michigan winter where you might spend $1,200 on gas from November through March, that efficiency gap adds up fast.

Single-stage vs. two-stage vs. modulating. A single-stage furnace has one setting: full blast. A two-stage furnace has a lower setting for milder days and full capacity for the deep cold. A modulating furnace adjusts continuously, ramping up and down to hold your set temperature within a degree. Two-stage and modulating systems cost more upfront but run quieter, distribute heat more evenly, and use less gas overall.

Brand. We install Carrier and Lennox, among other brands. There's a difference between economy, mid-range, and premium product lines within each brand. A builder-grade Carrier is not the same furnace as a Carrier Infinity. We'll walk you through the options and explain what you're actually getting for the money.

Venting changes. If you're switching from an 80% furnace (metal flue) to a 90%+ unit (PVC sidewall vent), the new venting adds labor and materials. This is common and usually runs $300 to $800 extra. It's a one-time cost that's part of the upgrade.

Permits and code compliance. Ottawa County and Kent County both require permits for furnace installations. A legitimate contractor pulls the permit — it's typically $75 to $150 and ensures the work gets inspected. If a contractor tells you they "don't bother with permits," that's a red flag.

What Should Be Included in the Price

When you get a quote for furnace installation, make sure it covers all of this:

• The furnace itself — specific brand, model number, and efficiency rating in writing
• All labor — removal of old unit, installation, ductwork connections, electrical, gas line
• Permit — pulled by the contractor, not by you
• Removal and disposal of the old furnace
• New thermostat or thermostat hookup — if you're upgrading to a communicating system, the thermostat may be part of the package
• Venting — new PVC venting if upgrading to high-efficiency
• Post-installation testing — combustion analysis, gas leak check, airflow verification
• Warranty registration — most manufacturers require the installing contractor to register the equipment for the full warranty to apply

If a quote is just one line that says "furnace installed — $4,500" with no details, ask for an itemized breakdown. You have a right to know what you're paying for.

80% AFUE vs. 96% AFUE: Running the Numbers

This is the decision most homeowners in our area wrestle with. Let me lay out the math.

Say you're choosing between an 80% single-stage furnace installed for $4,000 and a 96% two-stage unit installed for $6,800. That's a $2,800 difference upfront.

If your annual gas heating cost would be $1,400 with the 80% unit, the 96% unit cuts that to roughly $1,167 — a savings of about $233 per year. At that rate, the efficiency upgrade pays for itself in about 12 years. But here's the thing: gas prices have been climbing, and Michigan winters aren't getting shorter. If gas costs rise even modestly, that payback shrinks.

The two-stage unit also gives you something the numbers don't show: comfort. It runs on low fire 70-80% of the time, which means longer, gentler cycles, more even heat throughout the house, and a furnace you barely hear. The single-stage blasts on, heats up fast, shuts off, and repeats. Some people don't care. A lot of our customers in Grandville and Jenison tell us the comfort difference alone was worth the upgrade.

For most homeowners in West Michigan, I recommend the high-efficiency route. You're going to own this furnace for 15 to 20 years. You'll recover the extra cost in fuel savings and get a quieter, more comfortable system in the meantime.

That said, if budget is tight and you need reliable heat right now, an 80% furnace from a good brand, properly installed, will keep your family warm for 20 years. There's no shame in that choice.

Why the "Cheapest Quote" Can Cost You More

When you're getting quotes, you'll probably see a range. Maybe one contractor comes in at $3,800 and another at $5,200 for what seems like the same job. Before you go with the low number, ask a few questions:

Is it the same equipment? A builder-grade furnace and a mid-range model from the same brand can be $600 to $1,000 apart. Check the model number, not just the brand name.

Are they pulling a permit? Skipping the permit saves the contractor money and puts you at risk. Unpermitted work can cause problems with insurance claims and home sales.

What warranty do you get? Some contractors offer one year on labor. Others include five or ten years. That matters when something goes wrong in year three.

Who's doing the work? Is the contractor doing the installation, or are they subbing it out? A sub who's never seen your house and is trying to get in and out fast may not do the same quality work.

What about the ductwork? The cheapest quote might not include sealing leaky duct connections, replacing a damaged return drop, or correcting an airflow problem. They bolt in the furnace and leave, and you wonder why some rooms are still cold.

I've gone to plenty of homes in the Grand Rapids area to quote a furnace replacement and found that the previous system was installed poorly — wrong size, ductwork hacked together, no permit pulled. That homeowner "saved" $800 on the install and spent the next decade with high bills and uneven heat.

How Mazure's Handles Pricing

Here's how we do it. I come to your house, look at your current system, check the ductwork, measure the space, and talk to you about what matters most — budget, efficiency, comfort, whatever your priorities are. Then I give you a written quote with the brand, model number, efficiency rating, and everything that's included. No surprises.

I'm not going to tell you your furnace is dangerous when it isn't. I'm not going to push the most expensive system if a mid-range unit does the job. And I'm not going to lowball you on the quote and add charges once the old furnace is already out.

If you want to get other quotes too — and you should — I'll tell you what to look for and what questions to ask. That's not something you hear from every contractor, but I'd rather earn your business on merit than win by default.

We also offer financing options to help spread the cost over time. A new furnace is a big expense, and not everyone can write a check for $6,000. Monthly payments in the $80 to $150 range make the upgrade a lot more manageable.

When to Replace (and When Not To)

Not every old furnace needs to be replaced. If your system is under 15 years old, the repair is under $500, and it's been well-maintained, fixing it usually makes more sense. We cover this in detail in our repair vs. replace guide.

But if your furnace is 18-plus years old, needs a major repair like a heat exchanger or control board, and you're noticing higher gas bills every year, replacement starts making financial sense. You're going to spend the money either way — the question is whether you spend it on repairs for a system that's declining or put it toward a new one that'll last another 20 years.

The worst time to make this decision is during a breakdown in the middle of January. If your furnace is getting up there in age, start getting quotes in the fall when contractors aren't slammed and you have time to compare options. You'll make a better decision without the pressure of a cold house.
