Propane Furnace Installation Cost Factors
The size of your home and the type of propane furnace you choose significantly affect your total furnace installation costs, along with a variety of other factors. Here’s a closer look at how your final price breaks down.
Furnace Size
Sizing matters when it comes to buying a new furnace. An undersized furnace will struggle to heat your rooms, while an oversized model wastes energy and money. Your home’s square footage informs the size of the propane furnace that you need to install. Here are average costs, including labor and materials, for various-sized furnaces:
| Furnace Size (BTU per Hour) | Home Size (Sq. Ft.) | Average Cost (All-In) |
|---|---|---|
| 40,000–60,000 | Up to 1,200 | $2,000–$ 3,500 |
| 60,000–80,000 | 1,200–2,000 | $3,000–$5,000 |
| 80,000–120,000 | 2,000–3,500 | $4,000–$7,500 |
Furnace Type
There are three common types of propane furnaces, each offering different efficiency levels and coming at a different upfront cost.
| Furnace Type | Average Installation Cost | Average Unit Cost |
|---|---|---|
| Single-stage | $700–$1,200 | $1,200–$2,300 |
| Two-stage | $900–$1,400 | $1,600–$2,800 |
| Modulating | $1,200–$1,700 | $2,300–$3,800 |
Efficiency
You can choose between standard-efficiency furnaces (80%–90% AFUE) and high-efficiency models (90%–99% AFUE). Although high-efficiency units cost more upfront, they consume less fuel and lower your long-term running costs.
Labor
Labor for installing a propane furnace falls between $1,000 and $3,100. Most HVAC pros either quote a flat project price or bill hourly at $75 to $150 for 10 to 20 hours of work.
Maintenance Costs
Plan on $100 to $300 per year for a professional propane furnace tune-up—money well spent to keep efficiency high and avoid breakdowns and future furnace repair costs.
Installing a Propane Tank
When you install a propane furnace, you’ll need a propane tank on your property to store the fuel. Propane tank installation costs $600 to $2,500, depending on whether you opt for above- or below-ground installation.
Does Installing a Propane Furnace Increase Home Value?
Yes, installing a propane furnace can have a positive impact on the value of your home. Swapping an outdated system for a new high-efficiency propane furnace can lift your home’s value—especially if the existing unit is nearing the end of its life. A new system will help you save on your heating bills, and is an attractive feature to prospective buyers if you’re selling your home.
Budgeting for the Cost to Install a Propane Furnace
Consider these cost-saving strategies to make installing a propane furnace more wallet-friendly:
Book ahead: Aim for a spring or summer install when crews are less busy and rates tend to dip.
Consider long-term costs: High-efficiency models save fuel costs over time.
Check rebates: Look for federal, state, or local rebates for energy-efficient furnaces.
Compare quotes: Collect at least three detailed bids from licensed local furnace installation pros so you can weigh cost, warranty, and timeline.
