Prices for liquid propane (LP) gas furnaces vary by efficiency, size, installation complexity, and regional labor costs. The typical cost to buy and install a new LP gas furnace ranges from about $3,500 to $9,500, with most homeowners paying $4,800-$7,500 for mid-range 80%+ AFUE units paired with standard ductwork. The main cost drivers are system size (BTU), efficiency rating, and whether an accompanying air handler or duct modifications are needed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| LP furnace unit price | $1,800 | $3,200 | $5,000 | Includes basic cabinet, burners, heat exchanger |
| Installation labor | $1,200 | $2,000 | $3,000 | Including basic venting and gas line hookup |
| Vent materials and venting work | $400 | $900 | $2,000 | Horizontal or vertical vent runs |
| Permits and inspections | $50 | $200 | $500 | Depends on locality |
| Thermostat and controls | $60 | $180 | $400 | Smart or programmable options |
| Removal of old unit | $100 | $400 | $1,000 | Disposal included in some packages |
Typical LP Gas Furnace Price Range by System Size
Most buyers pay for a mid-size LP furnace around 60,000 to 80,000 BTU, which handles a typical 1,800–2,400 square foot home in moderate climates. The low end covers smaller homes or 80% AFUE models, while the high end reflects 90%+ AFUE units with enhanced features and ductwork tweaks. Assumptions: Midwest or South residential labor rates, standard 1-story home, standard installation, basic venting.
Size-based pricing snapshot shows how unit size translates to cost. 60k BTU units typically cost $2,000-$3,800 for the furnace itself, with installed ranges of $4,800-$7,500. Larger 80k–100k BTU systems push the installed price toward $6,000-$9,500 in many markets, depending on ductwork and gas line upgrades.
Representative scenarios by home type
- Small house (1,000–1,400 sq ft): 40k–60k BTU, installed $4,000-$6,000.
- Mid-size home (1,400–2,000 sq ft): 60k–80k BTU, installed $4,800-$7,500.
- Large home or difficult install (over 2,000 sq ft): 90k–100k BTU, installed $7,000-$9,500.
What a Typical LP Furnace Quote Breaks Down Into
A quote usually splits into four to six components, with 4–6% variation by region. The main parts include the furnace unit, labor, venting, permits, and controls. The following table shows a common breakdown across many residential installs.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace (LP, 80%–95% AFUE) | $1,800 | $3,200 | $5,000 | Gas valve, heat exchanger, burner |
| Labor for install | $1,200 | $2,000 | $3,000 | Vent connection, gas line, condensate if applicable |
| Vent and chimney work | $400 | $900 | $2,000 | PVC or metal vent, routing |
| Permits/inspections | $50 | $200 | $500 | Local jurisdiction fees |
| Thermostat/controls | $60 | $180 | $400 | Non-programmable to smart |
Assumptions: standard ceiling height, no major ductwork changes, standard accessibility.
Key Variables That Drive LP Furnace Pricing
Several factors can swing the final price by thousands of dollars. Efficiency rating (AFUE) and system size are the two biggest levers. Higher efficiency (95% AFUE) costs more upfront but saves on fuel use over time. Assumptions: single-family home, normal access, standard 2-stage operation possible.
- range: 80% to 95%+; higher efficiency equates to higher equipment cost and sometimes upgraded burners and controls.
- and required repairs; leaky or poorly insulated ducts add $500-$2,000 to the bill.
- and obstruction level; long, complex vent runs can add $300-$2,000.
- if the existing line cannot support the new furnace; typical add-on $150-$800.
- from basic to Wi‑Fi connected or smart zoning; price range $60-$400 per unit.
Ways to Cut LP Furnace Price Without Compromising Safety
Smart shopping and scope management can trim costs. Focus on necessary scope changes and avoid premium add-ons unless needed. The following practical moves help reduce the price without sacrificing reliability.
- Match furnace size to loads with a professional heat calculation to avoid oversizing.
- Consider mid-range AFUE (85%–90%) instead of top-tier 95%+ unless you live in a very cold climate.
- Use existing vent paths if feasible and plan for minimal ductwork changes.
- Bundle installation with routine maintenance to secure a better labor rate.
- Compare quotes from at least 2–3 contractors to spot bundled discounts or seasonal price dips.
Prices can shift by region due to labor and fuel costs. Coastal markets often have higher labor rates than rural Midwest areas. The ranges below illustrate typical regional spreads, not a guaranteed quote.
| Region | Low | Average | High | Notes |
|---|---|---|---|---|
| Northeast | $4,700 | $7,000 | $9,500 | Higher labor and code requirements |
| Southeast | $4,500 | $7,000 | $9,000 | Moderate climate, mid-range costs |
| Midwest | $4,200 | $6,500 | $8,500 | Common pricing, accessible installs |
| West | $4,900 | $7,600 | $9,800 | Varies by urban vs rural |
Consider a 60,000 BTU LP furnace installed in a 1,600–2,000 sq ft home with standard ducts. The following example mirrors a typical local project. Furnace price and installation fall within a mid-range band, with modest duct adjustments. The total would likely be in the $5,500-$7,500 range before tax credits or rebates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| LP furnace unit | $2,100 | $3,000 | $4,000 | 80%–85% AFUE |
| Labor | $1,400 | $2,100 | $2,900 | Standard install |
| Vent/duct work | $350 | $750 | $1,200 | Minimal rerouting |
| Permits | $40 | $150 | $350 | Local rules |
| Thermostat | $60 | $150 | $250 | Smart option adds cost |
Annual energy costs depend on climate, efficiency, and usage. Higher AFUE saves fuel, but payback depends on heating season length. A mid-range LP furnace (80%–90% AFUE) for a typical Midwest winter might add $180–$360 per year in fuel consumption relative to older noncondensing units, assuming similar heat loads and propane prices around $3.50–$4.50 per gallon.
Quotes commonly itemize labor hours, crew size, and equipment components. Expect standard crew sizes of 2–3 for average homes and note any crane or scissor lift needs for multi-story installs. A practical breakdown helps compare apples-to-apples across bids.
| Item | Typical Range | Notes |
|---|---|---|
| Labor hours | 6–12 hours | Depending on ductwork and vent length |
| Crew size | 2–3 workers | Residential |
| Equipment rental | $0–$350 | Manifolds, ladders, or lifts |
| Gas line upgrade | $150–$800 | Pressure considerations |
Local rebates or utility incentives can lower the installed price. Check if propanegas models qualify for efficiency rebates or utility-based incentives. Rebates may reduce net cost by hundreds to over a thousand dollars depending on the region and program year.
