3-Ton Heat Pump Cost
A 3-ton (36,000 BTU/hr) heat pump is the most common residential size, suited to roughly 1,500-2,000 sqft. Plan-level installed cost, sizing guidance, and the rebates that still apply in 2026.
Quick answer: $8,000-$16,000 installed for a ducted 3-ton; cold-climate equipment adds $1,500-$3,500; high-cost states (CA, HI, NY, MA) run toward the top. Refine by state and home below.

Surprise odds are approximate planning estimates, not measured rates; cost ranges are sourced where shown. How this works.
Method: each cost line is drawn from a triangular distribution and correlated by a shared market factor (~0.5), then sampled across 10,000 outcomes (a Monte Carlo simulation); the most-likely value and range emerge from the simulation, not the band. A planning simulation, not a quote.
Frequently asked questions
How much does a 3-ton heat pump cost installed?
A 3-ton (36,000 BTU/hr) ducted central heat pump runs $8,000 to $16,000 installed nationally, per NREL benchmark data and 2026 installer surveys. A 3-ton system suits roughly 1,500 to 2,000 sqft in a moderate climate. Cold-climate (NEEP-listed) equipment adds $1,500 to $3,500. State labor rates shift the band — California, Hawaii, and the Northeast run highest.
What size home does a 3-ton heat pump heat and cool?
A 3-ton unit is sized for about 1,500 to 2,000 sqft in a moderate climate (IECC zones 3 to 5), assuming average insulation. Tighter, newer homes may be fine at 2.5 tons for the same footprint; older, leaky homes may need 3.5 tons. A Manual J load calculation by a licensed contractor is the proper sizing method — the per-sqft rule of thumb is a starting point, not a spec.
Is 3 tons the most common residential heat pump size?
Yes. The 3-ton size covers the largest share of U.S. single-family homes, which is why it is the most-quoted residential heat pump capacity. If your home is meaningfully larger than 2,000 sqft or has poor insulation, see the 4-ton and 5-ton pages; for smaller homes, see the 2-ton page.
What rebates apply to a 3-ton heat pump?
The federal 25C credit expired Dec 31 2025 under OBBBA. State and utility programs plus DOE Home Energy Rebates (where launched) still apply and are not capacity-dependent — they key off equipment efficiency and household income, not tonnage. Use the calculator above to see programs for your state.
