Proper maintenance can help extend the lifespan of any furnace and keep it in good working order, but every furnace will eventually wear out and require replacement. When this happens, homeowners in Southeast Michigan can usually expect to pay between $3,500 and $12,000 for a new furnace.
The exact price you’ll pay for a new furnace will depend on a number of important factors, including some that are obvious and others that may be surprising. The best way to find out exactly how much you’ll have to pay is by contacting a reputable HVAC contractor, but we’ll share some of the things that’ll help determine the costs you’ll face, so you can start budgeting appropriately.
Factors Influencing the Cost of a New Furnace in Southeast Michigan
A few of the factors that play a role in determining the costs you’ll face for furnace replacement in Southeast Michigan include the following.
The Type of Furnace You Purchase
The type of furnace you choose — electric, natural gas, propane, or oil — will play a significant role in determining your overall furnace replacement costs.
Electric furnaces are the most affordable option, often costing between $600 and $2,800. Natural gas (the most common choice in Michigan) and propane heaters offer a mid-tier price point, which generally ranges from $700 up to $3,200 or more. Oil heaters are the most expensive option, and they generally cost between $1,000 and $4,000.
The Size of the Furnace
Furnace size is measured by the number of British Thermal Units (BTU) the unit produces. You’ll need the help of a licensed HVAC technician to determine the right size for your house, based on your house’s square footage and rate of heat loss.
Small, well-insulated homes may be able to stay warm with a furnace capable of producing 40,000 BTU, while larger homes may require furnaces that can pump out 120,000 BTU or more.
The Furnace’s Efficiency Rating
Furnace efficiency is measured by something known as Annual Fuel Utilization Efficiency (AFUE).
This basically explains how efficiently the furnace converts fuel into warm air. Furnaces with AFUE ratings in the 80% range are generally considered baseline units, while high-efficiency units have AFUE ratings exceeding 90%. Due to recent regulations, most new furnace installations in Michigan must have AFUE ratings of 95% or more.
These high-efficiency furnaces can cost $1,000 to $2,500 more than less efficient models. However, their superior efficiency means they require less fuel, which produces long-term savings that may offset the higher purchase price.
The Need for Ductwork Repairs
A complete HVAC system inspection is generally performed before a technician can identify the proper furnace size for your home and provide you with an estimate of the costs. During this inspection, technicians occasionally notice that the ductwork has become damaged over time.
This will result in additional costs for your furnace replacement project, but they’ll help ensure your overall system works efficiently.
Old Furnace Disposal
Installing a new furnace means you’ll have to have the existing furnace removed and disposed of. Most HVAC contractors will gladly handle this for you, but they will charge for this service.
On the other hand, you can dispose of your old furnace yourself, once your HVAC technician has removed it. However, this can be somewhat challenging, as you’ll have to find a facility that accepts old furnaces — you can’t just put it out on the curb with your trash.
In either case, there will be costs associated with the disposal of your old furnace, but they will vary depending on which option you choose.
The Need for Permits and Inspections
Furnace replacement almost always requires you (or more commonly, your HVAC contractor) to secure a permit from your local building department. These kinds of permits have fees, generally in the $50 to $250 range. However, the exact fees you’ll have to pay will vary depending on the specific jurisdiction you’re in.
The Need for Gas Line Alterations
In some cases, you may need to have alterations carried out on the gas lines in your home to accommodate your new furnace. These kinds of alterations usually cost between $15 and $25 per linear foot in Michigan. This means that most minor alterations cost around $300 to $800, but complex alterations may cost $2,000 or more.
Saving Money on a New Furnace: Tips & Tricks
Though furnace replacement can involve significant expenses, there are a few ways homeowners can save a little bit of money.
For starters, you can look for any federal, state, or local rebates or tax incentives available to you. The 25C Federal Tax Credit, for example, allows you to deduct 30% of the cost of a high-efficiency gas furnace (capped at $600). You can also have the furnace installed during the spring or summer, when HVAC professionals have fewer time constraints.
Additionally, you can do things that will help you save money over the long term. For example, you can purchase a high-efficiency furnace. This will cost you more upfront, but you will enjoy long-term energy savings, which will often exceed the premium you paid for the high-efficiency furnace.
Also, remember to have your new furnace maintained at least once (and ideally twice) each year. This will help ensure it works well and lasts as long as possible, so that you can enjoy the maximum value it can provide.

What does a new furnace cost in Michigan?
Most new furnaces will cost between $3,500 and $12,000, including parts and labor, in Southeast Michigan. The size of your home, the quality of the furnace, and many other factors will help determine exactly where your new furnace will fall in that price range.

What is the $5000 rule for furnaces?
The $5,000 rule is a guideline intended to help homeowners decide whether to replace or repair their furnace.
