Up to 98% efficient
Older furnaces run around 60–80% efficient. A new high-efficiency gas furnace turns nearly all the fuel you pay for into heat, which shows up on the bill every month, not just once.

Why replace
What a new furnace actually gets you
If your furnace is 15+ years old, running loud, or costing more every winter, a modern high-efficiency furnace pays you back in ways an old one can't.
Lower bills
Comfort
Even, quiet heat
Variable-speed furnaces hold a steady temperature instead of blasting and coasting, so no more cold rooms over the garage, and they run quiet enough you'll forget it kicked on.
Reliability
No 2am breakdowns
Aging furnaces fail on the coldest night of the year. That's not luck, that's load. A new system takes that gamble off the table for the next couple of decades.
Safety
A fresh heat exchanger
Cracked heat exchangers are the real risk on an old furnace, a carbon-monoxide concern you can't see. A new unit resets that clock with modern safety controls built in.
Rebates
Money back on efficiency
Qualifying high-efficiency furnaces can earn utility and federal efficiency rebates. We tell you what's on the table the week you buy and fill out the paperwork for you.
Warranty
Covered for the long haul
New systems carry a manufacturer parts warranty (10 years on most), and we register it for you so it's actually valid when you need it.

The Rockit difference
Why homeowners pick us over the big names
A furnace is only as good as the install. Most callbacks and comfort complaints come from a system that was guessed at, not sized. We do it the right way, every time.
- Manual J on every job. A real, room-by-room load calculation on every install, so the furnace fits your house, not the sticker on the old one.
- An expert crew, 30+ years deep. The tech who quotes it is on site the day it's installed. Same faces, start to finish.
- Attention to detail most crews skip. We test static pressure, cover your floors, and leave the mechanical room cleaner than we found it.
- Fixed, written price. Three itemized options with the monthly payment next to each. No surprise line items on the invoice.
- Comfortmaker Elite Dealer. Certified on the equipment we install, with permits, inspection, and warranty registration handled for you.

Straight answers
Furnace replacement questions, answered
How much does a new furnace cost in West Michigan?
It depends on the size of your home, the efficiency level, and whether any ductwork changes are needed. We quote a fixed, written price after a real Manual J load calculation (three itemized options with the monthly payment printed next to each), so you see the number before anything is ordered.
How long does a furnace replacement take?
Most furnace replacements are a one-day job. We cover the floors, pull the old unit, set and wire the new furnace, start it up, and walk you through it before we leave.
Should I replace my furnace or repair it?
A quick rule of thumb: multiply the furnace's age by the repair cost. Past about $5,000, the repair stops paying for itself. Furnaces over 15–20 years old, with rising bills or repeat repairs, are usually better replaced than patched.
Do you install high-efficiency and Comfortmaker furnaces?
Yes. We're a Comfortmaker Elite Dealer and install high-efficiency gas furnaces sized to your home. If a heat pump or a furnace-and-AC combo makes more sense for your situation, we'll tell you that too.
