Figures are for the Columbia metro area in November 2026. Rural edges may add trip fees; Downtown Columbia & the District sits at the top of these ranges.
HVAC prices across Columbia
Same city, four kinds of job. Older buildings in Downtown Columbia & the District take longer, bigger homes in Jefferson City & Ashland need bigger systems, and Mizzou & East Campus usually comes in at or under the city typical.
Downtown Columbia & the District
- Installed
- $3,550–$8,450 installed
- Typical job
- $5,000–$6,700 / 3-ton AC swap
Condos, row houses and older buildings. Condensers often sit on roofs or in tight side yards, and paid parking, freight elevators and building rules all add labor.
North & East Columbia
- Installed
- $3,450–$8,100 installed
- Typical job
- $4,850–$6,400 / 3-ton AC swap
Older houses next to new infill. The swap itself is standard; the extras are undersized ducts, old wiring and line sets that need replacing for the new refrigerant.
Mizzou & East Campus
- Installed
- $3,250–$7,550 installed
- Typical job
- $4,600–$5,950 / 3-ton AC swap
Rentals and older houses near campus. Landlord jobs tend to be quick like-for-like swaps of smaller systems, which keeps prices a little under the city average.
Jefferson City & Ashland
- Installed
- $3,400–$8,150 installed
- Typical job
- $4,750–$6,450 / 3-ton AC swap
Bigger homes with garages and attics. Many need 4 to 5 tons or two systems, and attic air handlers take longer to swap than ones in a garage or closet.
Real-world HVAC costs in Columbia
Here's what common HVAC jobs cost in Columbia 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 Columbia jobs land near $5,300; a 17+ SEER2 unit adds about $1,800.
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 $8,800.
Switch from AC + furnace to a heat pump
A 3-ton heat pump on existing ducts, typically $7,200. Keeping the furnace as backup (dual-fuel) runs $6,400–$15,250.
Cool one room with a mini-split
A 12,000 BTU single-zone mini-split for a bedroom, office or addition, typically $3,500. A 9,000 BTU unit for a small room is $2,000–$4,300.
Cool a whole home with no ducts
A 4-zone ductless system, typically $10,800. Adding ducts for central AC instead costs $2,200–$8,400 before the equipment.
How much does HVAC cost in Columbia?
$3,400–$7,700 installed, with $5,300 the typical Columbia price. The spread is mostly the equipment tier and the install: a standard unit on a ground pad is a one-day job, while rooftop condensers, attic air handlers and new line sets add hours.
If the furnace is old too, doing both at once ($5,850–$14,350) usually costs less than two separate jobs. A 3-ton heat pump that heats and cools runs $4,950–$11,250, and a high-efficiency zoned heat pump $9,000–$18,850.
Central AC, heat pump and furnace prices in Columbia (2026)
A 3-ton central AC runs $3,400–$7,700, a 3-ton heat pump $4,950–$11,250, and a gas furnace $2,500–$7,200, all installed.

AC or heat pump in Columbia? A heat pump costs about $1,900 more than a 3-ton AC at the typical price, but it also replaces your heating. If your furnace is old, compare a heat pump with the $8,800 AC + furnace swap, not with the AC alone.
What moves an HVAC quote in Columbia:
- Size: a 2-ton system runs about $4,450 and a 5-ton about $7,450 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 $1,800.
- Access: attic air handlers, rooftop condensers and tight closets add labor, most often in Downtown Columbia & the District.
- Line set and coil: a new line set runs $170–$570, 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 Columbia 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 Columbia by home size
About $4,800 for a 2.5-ton AC (1,000–1,600 sq ft), $5,300 for 3 tons (1,600–2,000 sq ft), and $6,550–$7,450 for 4–5 tons in homes over 2,500 sq ft, typical Columbia prices on existing ducts.
Worked example: a 2,000 sq ft Columbia home with a 16-year-old AC and furnace. Replacing both runs about $8,800; switching to a 3-ton heat pump on the same ducts runs about $7,200; replacing only the AC is $5,300 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 $9,000–$18,850, and adding zoning to an existing system $1,550–$4,050.
Columbia HVAC costs by system type
| System type | Cost | Best for |
|---|---|---|
| Central AC, 3-ton (existing ducts) | $3,400–$7,700 installed | Homes with sound ducts and a furnace or air handler to pair with |
| Ductless mini-split, single zone (9,000–18,000 BTU) | $2,000–$6,450 installed | One room, an addition, or a home with no ducts |
| Multi-zone ductless mini-split (2–4 zones) | $4,050–$16,150 installed | Whole homes with no ducts, room-by-room control |
| Heat pump, 3-ton ducted (heats and cools) | $4,950–$11,250 installed | Mild and hot climates; replacing an AC and electric heat |
| Gas furnace + AC, replaced together | $5,850–$14,350 installed | Cold climates with natural gas and old equipment on both sides |
| Gas furnace only (80–96% AFUE) | $2,500–$7,200 installed | When the AC is newer than the furnace |
| Dual-fuel: heat pump + gas furnace | $6,400–$15,250 installed | Cold climates: electric heat most days, gas on the coldest |
| Cold-climate heat pump, 3-ton ducted | $8,550–$21,550 installed | Northern homes leaving gas, oil or propane |
| Central heat pump, high-efficiency with zoning | $9,000–$18,850 installed | Big or two-story homes with hot and cold rooms |
| Evaporative (swamp) cooler, roof-mounted | $1,150–$3,250 installed | Dry Western climates only |
| Geothermal heat pump (ground loop) | $13,500–$31,450 installed | Large lots and long stays in one home |
| Window or through-the-wall AC | $180–$1,050 installed | Single rooms and renters; cheapest way to cool |
Equipment vs installation: the Columbia AC bill
On a typical $5,300 3-ton swap in Columbia, the condenser and matched coil are roughly $2,100–$3,200 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 $430–$1,700 or more for a mini-split and won't cover the parts. Brand warranties often require a licensed installer.
What's included in a Columbia 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: $85–$220, often built into the quote
- New refrigerant line set: $170–$570 if the old one can't be reused
- New condenser pad: $35–$220
- Electrical panel upgrade: $740–$3,500, 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.
Columbia's climate
Heating drives system choice in Columbia: gas furnace + AC is the common setup, and electric options lean toward cold-climate or dual-fuel heat pumps. The federal floor for a new split AC here is 13.4 SEER2.
System size
Each ton adds equipment cost: about $4,450 for 2 tons and $6,550 for 4 tons at the typical Columbia 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 $2,200–$8,400.
Location: Downtown Columbia & the District vs Mizzou & East Campus
Downtown Columbia & the District jobs cost more because of access, parking and older buildings. Mizzou & East Campus 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 $140–$220 an hour.
- Get three quotes for the same system.Same tonnage, same SEER2 rating, model numbers on every quote. Columbia quotes for the same 3-ton swap run anywhere from $3,400 to $7,700.
- 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 $5,850–$14,350, less than two separate jobs.
- Keep up with tune-ups.A yearly tune-up at $65–$170 catches weak capacitors and low refrigerant before they kill a compressor ($1,150–$2,700).
Before you pay a deposit to a Columbia 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
