Most U.S. homeowners choosing between propane and natural gas want straight pricing: fuel cost, equipment, and installation. This article compares the cost of heating with propane vs natural gas, shows typical total and per-unit price ranges, and explains the main drivers that change a final quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Annual Fuel Cost (2,000 sq ft) | $1,200 | $1,800 | $3,200 | Depends on price per gallon vs therms, efficiency |
| New Furnace/Boiler | $2,000 | $4,500 | $8,500 | Includes installation, mid-efficiency to high-efficiency units |
| Fuel Delivery / Line/Tank | $500 | $1,500 | $5,000 | Propane tank vs gas line hookup |
| Total First-Year Cost | $3,700 | $7,800 | $16,700 | Includes fuel purchase, equipment, installation |
Typical Total Costs To Heat a 2,000 sq ft Home
Assumptions: Moderate climate, insulated 2,000 sq ft, existing ductwork, standard 80-95% AFUE furnaces.
A typical annual fuel cost runs about $1,200-$3,200 depending on whether a home uses propane or natural gas and on local fuel prices.
Example totals: natural gas homes often pay $1,200-$2,200/year in fuel; propane homes pay $1,800-$3,200/year. New equipment and installation push first-year costs to $3,700-$16,700. Per-unit fuel rates used: $0.90-$1.40 per therm for natural gas and $2.00-$4.00 per gallon for propane, with furnace efficiencies of 80%-95%.
Breakdown of Materials, Labor, Delivery, and Taxes
| Cost Component | Materials | Labor | Delivery/Disposal | Taxes |
|---|---|---|---|---|
| Furnace/Boiler | $1,200-$5,500 | $800-$3,000 | $0-$200 | $120-$600 |
| Propane Tank / Fill | $600-$3,000 | $200-$600 | $50-$200 | $20-$150 |
| Gas Line Hookup | $100-$800 | $400-$2,500 | $0-$150 | $10-$200 |
| Permits & Inspections | $0-$150 | $75-$250 | $0 | $0-$40 |
Materials and labor are the biggest share of the invoice; delivery and taxes add 5%-15% depending on location and fuel choice.
Typical contractor rates: $75-$125 per hour; furnace installs usually take 6-12 hours for a 1-2 person crew.
Fuel Price, Efficiency, and Tank/Line Size That Change the Final Quote
Small changes in fuel price, appliance efficiency, and tank/line capacity create the largest long-term cost swings.
Key numeric drivers: boiler/furnace AFUE (80% vs 95% changes fuel use by ~16%-20%), propane tank size (250 vs 500 gallons affects refill frequency and per-gallon price), and gas line distance (each additional 50-100 linear ft can add $300-$1,000). If a home needs a higher-capacity 120k BTU unit vs a 60k BTU unit, expect equipment costs to rise 30%-80%.
How To Lower Your Heating Bill With Scope and Timing Choices
Controlling scope—choosing a mid-efficiency unit and scheduling installation off-season—cuts first-year costs without drastic comfort loss.
Practical actions: accept 90% AFUE instead of 97% for lower upfront cost, bundle furnace and thermostat replacements, pre-buy propane in autumn when prices are lower, and obtain multiple quotes. Avoid high-margin weekend or emergency installs; standard scheduling reduces labor premiums by 10%-25%.
Regional Price Differences Between Northeast, Midwest, South, and West
Geography changes fuel and installation costs: the Northeast often pays 10%-30% more for propane and installation than the Midwest.
Typical deltas: Northeast +15%-30% on propane and labor, West Coast +10%-25% for labor and permits, Midwest baseline, South often -5%-15% for natural gas hookups where infrastructure is abundant. Urban installs can add 10%-50% for access, parking, and permit complexity.
Real-World Quote Examples For Three Households
| Scenario | Specs | Labor Hours | Per-Unit Rates | Total |
|---|---|---|---|---|
| Suburban Natural Gas | 2,000 sq ft, 95% AFUE, existing line | 8 | Gas $1.00/therm | $5,200-$7,000 |
| Rural Propane | 2,000 sq ft, 90% AFUE, new 500-gal tank | 12 | Propane $3.10/gal | $8,000-$12,500 |
| Older Home Retrofit | 1,600 sq ft, replace oil to gas, 80k BTU | 20 | Mixed fees | $12,000-$18,000 |
These examples show how tank installation, fuel type, and retrofit complexity push totals from about $5,000 to $18,000.
Installation Time, Crew Size, and Typical Service Rates
Installation time and crew size directly affect labor line items; bigger crews shorten duration but can increase hourly overhead.
Typical patterns: 1-2 techs for furnace swap (6-12 hours), 2-4 techs plus excavation for propane tank set (8-24 hours), retrofits converting oil to gas often require 2-4 days. Expect minimum charges of $300-$600 and emergency or weekend rates of +25%-50%.
