Walker has a real mix of housing. The Standale area and streets near Alpine Avenue have a lot of ranches and split-levels from the 1950s through 1970s — single-story layouts with basements, original windows in some cases, and ductwork that's been added onto over the decades. West of Alpine, newer subdivisions have two-story colonials and open floor plans with better insulation but more square footage to heat. Every one of these houses needs its own load calculation. We run a Manual J to figure out exactly how many BTUs your home needs based on square footage, insulation, window quality, ceiling height, and layout. An oversized furnace short-cycles and wastes energy. An undersized one can't keep up on a 5-degree night. We get the math right so you get consistent heat in every room.
Furnaces sold today range from 80% AFUE to 98% AFUE. That percentage tells you how much of the gas you pay for turns into heat. An 80% unit vents through a metal flue and works fine — it's the straightforward, lower-cost option. A 96% or 98% unit uses a secondary heat exchanger to pull more energy from the exhaust, vents through PVC, and cuts your gas bills noticeably. For most Walker homeowners, we recommend 95% or 96% AFUE — it's the sweet spot between upfront cost and long-term savings, especially in Michigan where you're running the furnace six months a year. We install Carrier, Lennox, Trane, Goodman, Rheem, York, and American Standard. We'll walk you through the options without pushing you toward the most expensive unit on the truck. Total installed cost for Walker homes typically runs $3,500 to $7,500, depending on efficiency, brand, and any ductwork modifications needed.
Most furnace installations take one day. We pull the old unit, inspect your ductwork and gas line, set the new furnace, make all connections, and test the system thoroughly before we leave. If your existing ductwork is undersized or leaking — common in those older Alpine-area ranches — we'll address that during the install so the new furnace can actually deliver its rated performance. We also handle the permit and city inspection requirements for Walker. We don't subcontract our installs. The same technicians who do your load calculation are the ones connecting your furnace. Financing is available, and we offer free estimates — no obligation, no follow-up sales calls. Just a written quote you can think about on your own time.
