Central Air Conditioning Service Across the Twin Cities & Nearby Towns

Repairs, replacements and tune-ups

Most cooling calls fall into one of three groups, and each has its own page.

Repairs. Something quit: the outdoor fan won't turn, the vents blow room-temperature air, or water is spreading across the basement floor. We find the cause, write down the price and fix it once you say yes. Most repairs are parts that wear out on a schedule, such as run capacitors, contactors, condenser fan motors and drain pumps. AC repair walks through each failure and what it costs.

Replacements. The compressor is gone, the coil leaks, or the system is old enough (and still on R-22) that fixing it is money poorly spent. We size the new system with a Manual J load calculation, and match the indoor coil to the outdoor unit. AC installation covers sizing, SEER2 ratings and the newer refrigerants.

Tune-ups. A spring visit to clean the condenser coil, test the capacitor, check the charge and clear the drain. It finds the weak capacitor in April instead of on the first 90-degree Saturday. The checklist is on our maintenance page.

Should you repair or replace your air conditioner?

Nobody should replace a working system because a capacitor failed, and nobody should put a new compressor in a 20-year-old R-22 unit. Most decisions fall somewhere between, and four things settle them: the refrigerant on the nameplate, the size of the repair, the age of the equipment and how the house feels while it runs.

Either way, you get the written repair price, and a replacement quote if you ask for one, so you're comparing two real numbers. Warranty status moves those figures, and AC repair shows how.

Which refrigerant does your AC use, and why does it matter?

The nameplate on the outdoor unit lists the refrigerant, and it changes the repair math.

• R-22. Production and import ended January 1, 2020. An R-22 system can keep running, but any refill has to come from reclaimed or stockpiled refrigerant, and national cost guides such as HomeGuide put that at $90–$150 per pound installed. A leak on an R-22 system usually tips us toward replacement. Our R-22 guide walks through the options.
• R-410A. The standard refrigerant in the years before 2025, and it is not banned. Existing R-410A systems can be repaired and recharged. On May 21, 2026, EPA removed the January 1, 2026 installation deadline, so R-410A equipment manufactured or imported before 2025 can still be installed.
• R-454B and R-32. Under the EPA Technology Transitions rule, residential air conditioners and heat pumps manufactured from 2025 on use lower-GWP refrigerants like these. They need an indoor coil built for them, so a new outdoor unit means a new coil.

Our technicians hold EPA Section 608 certification, which federal law requires for handling refrigerant.

How much does central air cost?

• Service call: a written, flat-rate repair price before we start, and the trip charge is waived when you approve it.
• AC tune-up: from $129, or $219 for the furnace and AC in one visit.
• Central AC replacement: $5,200–$9,800 installed, sized with a Manual J load calculation.
• Heat pump in place of an AC: $7,500–$14,500 installed.
• Ductless mini-split: $4,200–$12,500 installed.
• Warranty: a written 1-year parts-and-labor warranty on completed repairs, and a 2-year labor warranty on installs on top of the manufacturer's parts warranty.

Prices are the same in every town we serve, with nothing added for distance. The full list is on our pricing page, and the Minneapolis HVAC cost guide shows how those ranges apply to city houses. For what moves a replacement price up or down, read AC replacement cost in Minnesota. We take cash, check and credit cards, and financing is available on installs.

Cooling a Minnesota house

A short season that starts hard

An air conditioner here can sit idle from September to late May, then run for hours at a stretch through the first humid week of summer. Parts that were weak last August tend to quit right then.

Humidity matters as much as temperature. On a July day with the dew point in the 70s, much of what your AC does is pull water out of the air, and that only happens when it runs long enough for the indoor coil to stay cold and drip. An oversized unit cools fast, shuts off and leaves the house at 72 degrees and clammy. That's the usual result of sizing by copying the old nameplate.

Old houses, boilers and add-on air

Many 1920s–1950s houses in Minneapolis and Saint Paul got central air added to ductwork converted from gravity heat: the coil stacked on the furnace in a low basement, the condenser squeezed into a narrow side yard, and a story-and-a-half upstairs the ducts barely reach. Houses heated by boilers and radiators have no ducts at all, so cooling there usually means ductless mini-splits. Suburban split-levels and ramblers from the 1970s–90s often have returns sized for heating rather than cooling airflow, and newer two-story houses fight a hot upper floor.

Snow, cottonwood and your utility

Cottonwood fluff in June and utility load-control events on hot afternoons are covered on AC repair. In winter, keep condensers out from under the roof edge where snow and ice slide off, and read should you cover your AC in winter before you wrap one. A heat pump's outdoor unit runs all winter, so it needs snow and ice kept clear, especially through a January cold snap.

Electricity comes from Xcel Energy across much of the metro, and from co-ops such as Dakota Electric, Connexus Energy and Wright-Hennepin, or a city utility, in many other towns; in Wisconsin, Focus on Energy runs the statewide program. Cooling rebates change every year and some need a utility-registered contractor, so check your utility's current page and ask whether yours needs one. Dakota Electric, for example, lists an AC tune-up rebate open to any contractor and quality-installation rebates that need a registered one. The federal 25C tax credit that used to cover central air ended for equipment placed in service after December 31, 2025.

Heat pumps, mini-splits and humidity control

When an AC needs replacing, price a heat pump before you sign. A heat pump is an air conditioner with a reversing valve: it cools in July the same way, then moves heat into the house in spring and fall. Paired with your gas furnace (dual fuel), it carries the mild days and the furnace takes over in real cold. Heat pumps covers how they handle a Minnesota January.

If the house stays sticky with a right-sized AC, check that the furnace fan is set to Auto, not On. Basements and lake homes that stay damp all summer may need a whole-home dehumidifier.

How does a cooling service call work?

1. Call 612-429-3465 or send the form, and tell us what the system is doing.
2. The technician checks the simple things first: thermostat, breaker, disconnect and filter.
3. Then the outdoor unit (capacitor, contactor, fan and compressor draw), the refrigerant readings, and the indoor coil and drain.
4. You get one written, flat-rate price, and nothing is repaired until you approve it.
5. If replacement makes more sense, we say so and quote it from a Manual J load calculation, so you can compare.
