How Heat Pump Sizing Works
Heat pumps are sized in tons, where 1 ton = 12,000 BTU of heating/cooling capacity. The calculator estimates your needed tonnage based on house size and climate zone, using industry-standard rules of thumb.
For precise sizing, an HVAC contractor performs a Manual J calculation that accounts for insulation quality, window area, ceiling height, sun exposure, and occupancy. The calculator gives you a starting estimate — expect the actual quote to be within ±0.5 ton.
Air-Source vs Geothermal
Air-Source Heat Pump
Most common. Extracts heat from outside air. Works down to ~0°F.
Pros: Affordable, no ground drilling, fast install
Cons: Less efficient below 20°F, needs backup heat
Lifespan: 15-20 years
Geothermal (Ground-Source) Heat Pump
Uses stable ground temperature. Most efficient but expensive to install.
Pros: Highest efficiency, lowest operating cost, long lifespan
Cons: Most expensive install, requires yard space for ground loops
Lifespan: 25-50 years (indoor unit)
Cost Breakdown
| Component | % of Total | What it covers |
|---|---|---|
| Equipment (heat pump unit) | 55-65% | Outdoor compressor/condenser + indoor air handler |
| Labor (installation) | 20-30% | Removal of old system, install new, electrical, refrigerant |
| Materials (lines, pad, ductwork mods) | 8-12% | Refrigerant lines, pad, wiring, minor duct modifications |
| Permits & inspection | 5-8% | Electrical permit, HVAC permit, final inspection |
How Location Affects Your Cost
| Region | Labor | Materials |
|---|---|---|
| Midwest | 1x | 1x |
| Southeast | 0.9x | 0.95x |
| Southwest | 1.05x | 1.1x |
| Northeast | 1.3x | 1.2x |
| West Coast | 1.4x | 1.25x |

We've reviewed hundreds of quotes. These are the warning signs that a contractor may cut corners or overcharge:
- Quote without Manual J calculation: Real HVAC sizing requires load calculation. Phone estimates are guesses.
- Single brand pusher: Contractors who only offer one brand may prioritize commissions over your needs.
- No tax credit paperwork: Reputable installers provide ENERGY STAR documentation for IRA tax credits.
- Pressure to decide same-day: Quality HVAC contractors give you time to compare quotes.
Tax Credits & Rebates (Don't Miss These)
Federal Tax Credit (IRA): 30% of cost, up to $2,000 for air-source heat pumps. Through 2032.
Geothermal Tax Credit: 26% federal credit, no cap.
State Rebates: Varies $500-$5,000 by state. Check dsireusa.org.
Utility Rebates: Many utilities offer $200-$1,000 for ENERGY STAR certified units.
Combined incentives can reduce your effective cost by $2,000-$8,000. Always check before signing a contract.
Frequently Asked Questions
How much does a heat pump cost installed?
Air-source heat pumps cost $4,000 to $12,000 installed in 2026, depending on size (tons) and efficiency. A typical 3-ton high-efficiency unit runs $8,000-$12,000. Geothermal heat pumps cost $15,000-$30,000+ due to ground loop drilling. The calculator above estimates your cost based on house size and climate zone. Heat pumps cost more upfront than traditional furnaces but save $300-$1,500/year on energy (depending on your current heating source).
What size heat pump do I need for my house?
Heat pump sizing depends on house size and climate. Rule of thumb: 1 ton per 1,000 sq ft in warm climates, 1 ton per 700 sq ft in cold climates. A 2,000 sq ft home in a moderate climate typically needs a 2.5-3 ton unit. The calculator estimates this automatically. For precise sizing, an HVAC contractor performs a Manual J load calculation (accounts for insulation, windows, ceiling height, sun exposure). Oversized units short-cycle and dehumidify poorly; undersized units run constantly and can't keep up.
Is a heat pump worth it compared to a furnace?
For most US climates, yes. Heat pumps provide both heating and cooling in one system, eliminating the need for separate furnace + AC. They're 2-3x more efficient than electric resistance heat and competitive with gas furnaces on cost. Break-even is typically 5-10 years vs gas furnace replacement. In very cold climates (below -10°F), heat pumps need backup heat (electric resistance or gas), reducing savings. In warm/moderate climates, heat pumps almost always win on total cost of ownership.
How long does a heat pump last?
Air-source heat pumps last 15-20 years. Geothermal indoor units last 25+ years (ground loops last 50+ years). Lifespan depends on maintenance (annual service doubles expected life), usage patterns, and climate. Cold-climate heat pumps work harder and typically last 12-15 years. Signs of failure: frequent cycling, inadequate heating/cooling, unusual noises, rising energy bills, and refrigerant leaks. Most manufacturers offer 10-year parts warranties; labor is typically 1-2 years.
What is the difference between air-source and geothermal heat pumps?
Air-source extracts heat from outside air (works down to ~0°F with cold-climate models). Costs $4,000-$12,000 installed. Geothermal uses stable ground temperature (50-60°F year-round) via buried loops. Costs $15,000-$30,000+ installed but operates at 300-600% efficiency (COP 3-6) vs air-source's 200-300%. Geothermal pays back in 7-15 years vs air-source, then saves $500-$1,500/year. Geothermal requires yard space for loop installation (vertical drilling or horizontal trenching).
Are there tax credits for heat pump installation?
Yes — the Inflation Reduction Act provides a 30% federal tax credit (up to $2,000) for heat pump installation through 2032. ENERGY STAR-certified units qualify. Some states offer additional rebates ($500-$5,000). Check dsireusa.org for your state's incentives. Geothermal qualifies for a separate 26% federal tax credit (no cap). Combined incentives can reduce your effective cost by $2,000-$8,000 depending on location and system type.
