No cooling at all?
Get in touch first. Then, while a company is lined up, try the three checks below.
- Panel. Look for two breakers, one for the furnace or air handler and one for the condenser. A tripped one gets a single reset; a second trip means hands off.
- Thermostat. Cool mode, setpoint under the room temperature. A dark screen usually means fresh batteries.
- Filter. Swap it if it is caked. Frost on the copper? Turn cooling off and run the fan alone until it melts.
Older relatives, infants or anyone ill at home go to a cool room or a cooled building before you troubleshoot. The first hour, step by step.

Three steps
- Describe the problem once. Use the short form or call. A picture of the condenser sticker helps.
- One area company follows up. Expect a call or text to confirm the address and book a visit.
- The quote comes before the wrench. After diagnosing it, the technician names a price. Yes or no is your call.

More hot days, and fewer cool nights to recover in
From 1991-2020, the airport south of town saw 34.4 days a year hit 90°F. The 2016-2025 average is 42.7. This year reached 44 by October 24, 2026, capped by a 100°F afternoon on September 5, 2026 and a string of 11 straight 90 degree days that ended September 9, 2026.
Nights changed more than days. After sunset the condenser gets cooler air to dump heat into, and that is when a house gets pulled back to the setpoint. Lows of 70°F or warmer used to come 27.8 times a year; now it is 37.3. The typical July low is 69.2°F, and a muggy Boone County night keeps the coil condensing water long after the sun goes down.
All those extra hours land on the capacitor, the contactor and the fan motor, and a condenser coil clogged with cottonwood seed or mower clippings makes every hour harder. The parts that fail most here.

An older housing stock that heats and cools
Of the 90,618 housing units in our 14 ZIP codes, 36% went up before 1980 and 30% more from 1980 through 1999 (Census ACS 2020-2024). Houses that age often got central air years after the ducts went in, so ask whether the ductwork was ever matched to the equipment. The three city ZIPs hold the bulk of it: 65203 (West and South Columbia, 27,520 homes), 65201 (Central and East Columbia, 21,289 homes), 65202 (North Columbia, 20,425 homes).
Winter is the other half of the job. Across our ZIPs, 43% of occupied homes heat with electricity and 47% with utility gas (Census ACS), which is why so many replacement conversations here turn into heat pump conversations. Heat pumps in Columbia.

What Boone County homeowners ask us
What will an AC repair run me in Columbia, MO?
For 2026, Fixr puts the bulk of AC repairs in the $250 to $700 band, with $375 as the average, and This Old House gives $150 to $650 for routine fixes. Capacitors sit near the bottom of that; compressors run $600 to $3,000 and up. Those are national figures, and prices differ from one Columbia shop to the next, so have the price in hand before anyone starts.
My AC is 15 or more years old. Should I keep fixing it?
Small parts, yes. Big parts, usually no. Putting a compressor or an indoor coil into a unit that is near the end of its service life spends a lot on equipment with few summers left, while a contactor or capacitor costs little and buys you time to plan. This Old House puts the typical life of a home cooling system at 12 to 15 years.
The AC runs nonstop and the house still feels muggy. Is something broken?
Maybe not. In a wet mid-Missouri July the coil has to condense water out of the air on top of cooling it. If cool air comes out of the registers but the rooms feel damp, look at the fan switch (ON instead of AUTO), a unit too big for the house, or a dirty coil. If the registers aren't blowing cool, or the house can't recover overnight when July lows at the airport average around 69.2°F, call for service.
Can a heat pump handle a Columbia winter?
It can, if it is the right model. Over 2016-2025 the airport saw about 9.8 nights a year at 10°F or below. On nights like that many heat pumps hand off to electric strips or a gas furnace, while cold-climate units keep producing heat on their own. Ask for the quoted unit's output at 5°F.
Whose truck pulls into my driveway?
One independent HVAC company covering your ZIP. CoMo Cooling Desk doesn't send technicians; we route your request so you can skip the round of phone calls. Within Columbia city limits the work must be done under a City of Columbia mechanical license, and refrigerant handling everywhere requires EPA Section 608 certification.
