Spokane is pricier than 54% of the 195 US metros we price for HVAC work.
Replacing a 3-ton central AC in Spokane costs $3,750–$8,500 on existing ducts, with $5,850 typical. A 3-ton heat pump runs $5,300–$12,000, a gas furnace $2,700–$7,700, and a single-zone mini-split $2,400–$5,400.
Spokane has cold winters and hot, dry summer spells, so many homes run a gas furnace with AC added, and cold-climate heat pumps are the electric option.
Prices on this page are installed: equipment, labor, removal of the old unit and startup. A permit ($95–$240), a new line set ($190–$620) or duct repairs may be extra, so ask. Labor is usually 40–60% of the bill.

- Installed
- $3,950–$9,350 installed
- Typical job
- $5,550–$7,400 / 3-ton AC swap
Older homes and mid-rise buildings. A like-for-like condenser swap is routine, but rooftop units and long line runs push quotes toward the top of the range.
East Central & Hillyard
- Installed
- $3,850–$8,950 installed
- Typical job
- $5,350–$7,050 / 3-ton AC swap

Real-world HVAC costs in Spokane
Here's what common HVAC jobs cost in Spokane in 2026, a 3-ton central AC replacement on existing ducts, installed.
Swap a 3-ton AC on good ducts
Same spot, same size, matched indoor coil, old unit hauled away. Most Spokane jobs land near $5,850; a 17+ SEER2 unit adds about $2,000.
Replace the AC and gas furnace together
The usual move when both are 15+ years old. One install, one warranty, a matched system. Typical is $9,400.
Switch from AC + furnace to a heat pump
A 3-ton heat pump on existing ducts, typically $7,700. Keeping the furnace as backup (dual-fuel) runs $6,800–$16,350.
Cool one room with a mini-split
A 12,000 BTU single-zone mini-split for a bedroom, office or addition, typically $3,750. A 9,000 BTU unit for a small room is $2,100–$4,600.
Cool a whole home with no ducts
A 4-zone ductless system, typically $11,550. Adding ducts for central AC instead costs $2,400–$9,050 before the equipment.
How much does HVAC cost in Spokane?
A typical 3-ton replacement in Spokane is $5,850, inside a normal range of $3,750–$8,500. That price is about 6% below the US typical of $6,200. Most of the difference between quotes is efficiency, brand and how hard the old equipment is to reach.

The gap between an AC and a heat pump in Spokane is about $1,850 at the typical price. That gap buys heating as well as cooling, so it matters most when the furnace is near the end of its life.
What moves an HVAC quote in Spokane:
- Size: a 2-ton system runs about $4,900 and a 5-ton about $8,200 at the typical price. Ask for a Manual J load calculation.
- Efficiency: the minimum here is 13.4 SEER2; a 17+ SEER2 two-stage unit adds about $2,000.
- Access: attic air handlers, rooftop condensers and tight closets add labor, most often in Downtown, Browne's Addition & Garland.
- Line set and coil: a new line set runs $190–$620, and the indoor coil has to match the new refrigerant.
- Season: spring and fall bring the best prices; a breakdown during a summer heat wave brings the worst.
Ask every Spokane contractor for the same things: tonnage, SEER2 rating, model numbers for both the outdoor and indoor units, and whether the permit and line set are included. Compare those, not just the total. Get a quote for your heating and cooling work →
HVAC cost in Spokane by home size
About $5,300 for a 2.5-ton AC (1,000–1,600 sq ft), $5,850 for 3 tons (1,600–2,000 sq ft), and $7,200–$8,200 for 4–5 tons in homes over 2,500 sq ft, typical Spokane prices on existing ducts.
Worked example: a 2,000 sq ft Spokane home with a 16-year-old AC and furnace. Replacing both runs about $9,400; switching to a 3-ton heat pump on the same ducts runs about $7,700; replacing only the AC is $5,850 but leaves an old furnace in place.
Homes over 2,500 sq ft or with two floors often have two systems or zoning. A high-efficiency zoned heat pump runs $9,600–$20,150, and adding zoning to an existing system $1,650–$4,300.
Spokane HVAC costs by system type
| System type | Cost | Best for |
|---|---|---|
| Central AC, 3-ton (existing ducts) | $3,750–$8,500 installed | Homes with sound ducts and a furnace or air handler to pair with |
| Ductless mini-split, single zone (9,000–18,000 BTU) | $2,100–$6,900 installed | One room, an addition, or a home with no ducts |
| Multi-zone ductless mini-split (2–4 zones) | $4,300–$17,300 installed | Whole homes with no ducts, room-by-room control |
| Heat pump, 3-ton ducted (heats and cools) | $5,300–$12,000 installed | Mild and hot climates; replacing an AC and electric heat |
| Gas furnace + AC, replaced together | $6,250–$15,350 installed | Cold climates with natural gas and old equipment on both sides |
| Gas furnace only (80–96% AFUE) | $2,700–$7,700 installed | When the AC is newer than the furnace |
| Dual-fuel: heat pump + gas furnace | $6,800–$16,350 installed | Cold climates: electric heat most days, gas on the coldest |
| Cold-climate heat pump, 3-ton ducted | $9,100–$23,050 installed | Northern homes leaving gas, oil or propane |
| Central heat pump, high-efficiency with zoning | $9,600–$20,150 installed | Big or two-story homes with hot and cold rooms |
| Evaporative (swamp) cooler, roof-mounted | $1,250–$3,450 installed | Dry Western climates only |
| Geothermal heat pump (ground loop) | $14,400–$33,600 installed | Large lots and long stays in one home |
| Window or through-the-wall AC | $200–$1,150 installed | Single rooms and renters; cheapest way to cool |
Equipment vs installation: the Spokane AC bill
On a typical $5,850 3-ton swap in Spokane, the condenser and matched coil are roughly $2,350–$3,500 and the rest is labor, materials, the permit and overhead. Labor usually makes up 40–60% of an AC replacement.
Buying the unit yourself rarely saves much: many contractors won't install customer-supplied equipment, and the ones who do charge $470–$1,900 or more for a mini-split and won't cover the parts. Brand warranties often require a licensed installer.
What's included in a Spokane AC replacement (and what costs extra)
A standard replacement quote covers the outdoor unit, a matched indoor coil, refrigerant, connection to your existing ducts and wiring, removal of the old unit, and startup. Common extras:
- Permit and inspection: $95–$240, often built into the quote
- New refrigerant line set: $190–$620 if the old one can't be reused
- New condenser pad: $40–$240
- Electrical panel upgrade: $810–$3,800, mostly when adding a heat pump or more capacity
Ask for the AHRI certificate showing the matched rating of your outdoor and indoor units. It proves the system you paid for is the one that was installed.
Climate and what it means here
Spokane has cold winters and hot, dry summer spells, so many homes run a gas furnace with AC added, and cold-climate heat pumps are the electric option.
System size
Each ton adds equipment cost: about $4,900 for 2 tons and $7,200 for 4 tons at the typical Spokane price. A Manual J load calculation often shows a smaller system will do.
Efficiency rating
The federal minimum for a new split AC here is 13.4 SEER2. Higher ratings cost more upfront and pay back fastest where AC runs most of the year.
New refrigerants
New systems use A2L refrigerants (R-454B or R-32), so the indoor coil must match the outdoor unit. That's why condenser-only swaps are rare now, and why older R-410A systems cost more to service.
Ducts and access
Leaky or undersized ducts, attic air handlers and rooftop condensers add hours. Whole-house duct replacement runs $2,400–$9,050.
Location: Downtown, Browne's Addition & Garland vs South Hill & Gonzaga
Downtown, Browne's Addition & Garland jobs cost more because of access, parking and older buildings. South Hill & Gonzaga quotes usually sit at or a little under the city typical.
Season and urgency
Replacing on your schedule in spring or fall is cheaper than an emergency swap in a heat wave. After-hours repair labor runs $150–$240 an hour.
- Get three quotes for the same system.Same tonnage, same SEER2 rating, model numbers on every quote. Spokane quotes for the same 3-ton swap run anywhere from $3,750 to $8,500.
- Replace before it fails.If your system is 12–15+ years old, replace it in spring or fall. Emergency replacements in peak season leave no room to shop around.
- Right-size the system.Ask for a Manual J load calculation. An oversized AC costs more, cycles on and off, and leaves the house clammy.
- Check your utility for rebates.There is no federal tax credit for systems installed in 2026, but many utilities still pay rebates on efficient heat pumps and AC. Check before you sign; most require pre-approval or a listed contractor.
- Do the AC and furnace together if both are old.One install of both runs $6,250–$15,350, less than two separate jobs.
- Keep up with tune-ups.A yearly tune-up at $70–$190 catches weak capacitors and low refrigerant before they kill a compressor ($1,250–$2,900).
Before you pay a deposit to a Spokane HVAC contractor, get these in writing:
- Tonnage and how it was sized (a Manual J load calculation)
- Model numbers for the outdoor unit and the indoor coil or air handler
- The matched SEER2 (and HSPF2 for a heat pump) rating
- Whether the line set is new, flushed or reused
- Permit, inspection and removal of the old unit
- Thermostat, pad, disconnect and any electrical work
- Parts and labor warranty terms, and who registers the equipment
- Total price, deposit, and start and finish dates
