New Furnace Installation Done Right — Sized for Your Home, Built for Michigan Winters
When your furnace has reached the end of its useful life, the decision to replace it is one of the bigger home investments you'll make. We help homeowners across West Michigan make that decision clearly — no pressure, no upsell, just an honest assessment of what your home actually needs and what it will cost to run for the next 20 years.
Andringa's Mechanical is an authorized Ruud Pro dealer — one of a small number in West Michigan with that designation covering heating, cooling, and boiler systems. That status isn't a marketing badge. It means factory-backed warranty support, access to the full Ruud equipment line, and accountability that a non-authorized installer simply can't provide. Ryan Andringa has been in the HVAC trade since 2003, and furnace installation is work he's done hundreds of times across homes in Kalamazoo, Grand Rapids, Holland, and throughout the surrounding area.
When Does It Make More Sense to Replace Than Repair?
Not every struggling furnace needs to be replaced. We'll always look for a repair path first — but there are situations where replacement is the financially honest answer, and we'll tell you when you're in one of them.
The clearest indicators that replacement makes more sense than repair:
- Age over 15 years. Most furnaces are designed for a 15–20 year service life. A system past that threshold is approaching the end of its reliable operating window regardless of its current condition.
- Recurring repair costs. If you've spent significant money on repairs in the past two to three years, those costs are unlikely to stop. At some point, continued repair spending outpaces the cost of a new system.
- Declining efficiency. Older systems lose efficiency over time. A furnace running at 70% AFUE when it was rated for 80% is costing you more every month than the nameplate suggests.
- Pre-2025 R-410A refrigerant systems. If your system uses R-410A and is already aging, factor in that refrigerant availability and service costs are changing. For many homeowners, this shifts the replacement calculus earlier than it otherwise would.
If your system doesn't check these boxes, we'll tell you that too.
Why Sizing Matters More Than Almost Anything Else
The single most common installation mistake in the HVAC industry is improper sizing — and it happens in both directions. An oversized furnace short-cycles, meaning it heats your home in short bursts and shuts off before completing a full heating cycle. That creates uneven temperatures, excess humidity swings, and premature wear on the equipment. An undersized furnace runs constantly, can't keep up on the coldest Michigan days, and drives up your utility bills.
Proper sizing requires a Manual J load calculation — a room-by-room analysis of your home's heat loss and heat gain based on square footage, insulation levels, window placement, ceiling height, and local climate data. We perform this assessment before we recommend any equipment. The result is a furnace specification built around your home's actual thermal profile, not a contractor's inventory preference or a rule-of-thumb square footage estimate.
Right-sized equipment runs more efficiently, lasts longer, and keeps your home comfortable at every temperature West Michigan throws at it.
The Ruud Furnace Line — What You're Getting and Why
AFUE — Annual Fuel Utilization Efficiency — measures how much of the fuel your furnace burns actually becomes heat in your home. A furnace rated at 80% AFUE converts 80 cents of every dollar of gas into usable heat. Ruud furnaces are available from 80% AFUE up through 98% AFUE in their high-efficiency two-stage and variable-speed models. The higher the AFUE, the lower your monthly operating cost — and in Michigan's heating season, that difference adds up quickly. We'll show you the math on payback period so you can make the right call for your budget and your timeline.
Efficiency Ratings and What AFUE Means for Your Bills
AFUE — Annual Fuel Utilization Efficiency — measures how much of the fuel your furnace burns actually becomes heat in your home. A furnace rated at 80% AFUE converts 80 cents of every dollar of gas into usable heat. Ruud furnaces are available from 80% AFUE up through 98% AFUE in their high-efficiency two-stage and variable-speed models. The higher the AFUE, the lower your monthly operating cost — and in Michigan's heating season, that difference adds up quickly. We'll show you the math on payback period so you can make the right call for your budget and your timeline.
Energy Star Options and Utility Incentives
Several Ruud furnace models carry Energy Star certification, which can qualify for utility rebates through Consumers Energy and Michigan gas utilities. We'll identify which models qualify and what incentives are currently available in your area. In many cases, the combination of rebates and long-term operating savings meaningfully narrows the gap between a standard-efficiency and high-efficiency system.
Manufacturer Warranty and What Authorized Dealer Status Covers
Ruud furnaces carry a limited lifetime heat exchanger warranty and a 10-year parts warranty on registered equipment — but those warranties require installation by an authorized dealer to be valid. As an authorized Ruud Pro partner, we register your equipment at installation and ensure the warranty is fully in force from day one. If a non-authorized installer puts in your system, you may have a warranty on paper that won't hold up when you need it.
One Brand, Deep Expertise, No Confusion
We carry Ruud because we know it well, it holds up in Michigan conditions, and we can stand behind it completely. We're not going to walk you through a side-by-side brand comparison designed to overwhelm you into a decision. We'll tell you exactly which Ruud model fits your home, exactly what it costs to install, and exactly what you can expect from it over its service life.

Furnace Installation — Frequently Asked Questions
How much does it cost to install a new furnace in Michigan?
Furnace installation costs in Michigan typically range from $3,000 to $7,000 or more depending on system efficiency, home size, and any additional ductwork or venting modifications required. A proper site assessment is the only way to give you an accurate number — rule-of-thumb estimates without a load calculation aren't reliable. We provide a detailed written estimate before any work begins.How long does a furnace installation take?
Most residential furnace installations are completed in four to six hours. If your project involves significant ductwork modifications or venting changes, it may run longer. We'll give you a realistic time estimate when we schedule your installation.What's the difference between an 80% and a 96% AFUE furnace — is the upgrade worth it?
An 80% AFUE furnace is a solid, reliable choice with a lower upfront cost. A 96% AFUE system costs more initially but reduces your annual heating bills meaningfully — in Michigan's climate, the payback period on a high-efficiency upgrade is often five to eight years. We'll walk you through the actual numbers for your home so you can make an informed decision rather than a guess.Does furnace size depend on square footage alone?
Square footage is one input, but it's not the whole picture. Insulation quality, ceiling height, window area, home orientation, and local climate data all factor into a proper Manual J load calculation. A furnace sized on square footage alone is frequently wrong — either oversized or undersized — and both outcomes cost you money over time.What warranty comes with a Ruud furnace installed by Andringa's?
Ruud furnaces installed by an authorized dealer like Andringa's carry a limited lifetime heat exchanger warranty and a 10-year parts warranty on registered equipment. We handle the registration at installation so your coverage is in place from the first day the system runs.
