Relocating a furnace isn’t something most homeowners plan for, but it comes up more often than you might think. Whether you’re finishing a basement, remodeling, or simply tired of the noise, moving your furnace can free up valuable space and improve home comfort.
But there’s no way around it: moving a furnace is a big project. It’s not just sliding the unit into another room—it’s rerouting ductwork, running new gas and electrical lines, and ensuring the system meets modern building codes. These steps make the cost significant, often ranging from $1,000 to $5,000, with complex moves running even higher.
If you’re preparing your budget, it helps to look at the big picture first. Our full guide on How Much Does a New Furnace Cost? covers equipment pricing, labor averages, and installation basics—while this article zeroes in on what you’ll pay if relocation is part of the project.
Why Homeowners Consider Moving a Furnace
There are a few common reasons homeowners choose furnace relocation:
-
Space optimization: Freeing up basement or garage space for storage or living areas.
-
Noise reduction: Getting the furnace away from bedrooms or common areas.
-
Safety and code issues: Older installations may not meet today’s clearance or venting requirements.
-
Home remodels: Relocating the furnace during renovations or finishing a basement.
Average Cost to Relocate a Furnace
National Cost Range
According to HomeAdvisor, moving a furnace typically costs $1,000–$5,000, with average projects landing in the $3,000 range. However, if ductwork must be completely redesigned or the furnace is relocated across floors (like from a basement to an attic), costs can exceed $7,000.
What’s Included in the Price
Relocation costs generally cover:
-
Disconnecting the existing furnace
-
Rerouting or resizing ductwork
-
Extending or adding gas and electrical lines
-
Installing new venting and drainage (if high-efficiency)
-
Reconnecting and testing the system for safe operation
Factors That Affect Furnace Relocation Costs
Ductwork Modifications
Ductwork is often the most expensive part of relocation. A furnace’s location dictates how ducts are distributed throughout the house. Moving the furnace can require major adjustments.
-
Sealing or resizing ducts: $1,000–$3,000
-
Full ductwork redesign: significantly more
The U.S. Department of Energy reports that typical houses lose 20–30% of heated air through leaky ducts. Relocation is the perfect time to seal and insulate ducts for better efficiency.
Gas and Electrical Line Relocation
Running a new gas line can cost $250–$800, depending on the distance and accessibility. Upgrading electrical wiring or adding a dedicated breaker may add another $300–$1,000.
The Department of Energy emphasizes that proper installation is critical for safety. This is especially true when relocating a furnace, as improper connections can lead to dangerous gas leaks or electrical hazards.
Venting and Code Requirements
Venting requirements vary by furnace type. Standard models may need a chimney liner, while high-efficiency units often require new PVC vent pipes.
Building codes also affect placement. According to the International Code Council, clearance rules for combustion air and exhaust venting must be followed to prevent carbon monoxide risks.
Expect venting and code compliance to add $500–$1,500 to a furnace relocation.
Labor Rates and Accessibility
Moving a furnace within the same floor is less expensive than moving it to a new floor or into a tight crawlspace. Labor rates also vary widely by region, which can increase or decrease your overall bill.
When Moving a Furnace Makes Sense
Relocation costs are high, but there are scenarios where it’s the right call:
-
During a major remodel: If you’re already opening walls or replacing ductwork, it’s more cost-effective to move the furnace at the same time.
-
If current placement violates code: Clearance and venting issues can make relocation necessary.
-
To reduce noise: Relocating away from bedrooms or living areas can improve comfort.
-
For efficiency upgrades: A better location can improve duct performance and airflow.
Alternatives to Furnace Relocation
Before committing, consider these alternatives:
-
Soundproofing: Adding insulation or sound barriers to reduce noise.
-
Ductwork adjustments: Improving airflow without moving the furnace.
-
Replacing with a smaller unit: Modern high-efficiency furnaces take up less space, reducing the need for relocation.
How to Save on Furnace Relocation Costs
Relocating a furnace will never be cheap, but you can manage the price with smart planning.
Bundle with Other HVAC Upgrades
If you’re replacing your furnace or adding central air, combine the projects. This reduces labor overlap and saves money.
Get Multiple Quotes
Always request at least three quotes and ask for line-item details. This helps you see where costs are coming from and avoid overpaying.
Check Rebates and Tax Credits
If relocation involves replacing your furnace with a high-efficiency model, you may qualify for rebates or tax credits. Use the ENERGY STAR rebate finder to check available programs in your area.
Safety First: Why DIY Isn’t an Option
Unlike simple maintenance tasks, furnace relocation is never a DIY-friendly project. It involves gas, electricity, and venting—all of which carry serious safety risks if handled improperly. A licensed professional ensures the job meets building codes and passes inspection, protecting your home and family.
Final Thoughts from Alex Lane
Moving a furnace isn’t just a matter of convenience—it’s a major project with costs that often reach several thousand dollars. But in the right situations—like remodels, code compliance, or efficiency improvements—it can be a smart investment.
The key is to plan ahead. Get detailed quotes, weigh alternatives, and look for rebates to reduce the financial hit. Above all, work with a qualified professional to ensure your furnace operates safely and efficiently in its new location.
