For a St. Louis Park air conditioner that won't cool, we charge $79 for the trip and waive it once you approve the repair, with the flat-rate price written before we start. Call 7 days a week, 7am–9pm. Condensers squeezed into narrow side yards here often overheat because they can't breathe.
Cooling calls in St. Louis Park come in two kinds. On the main floor and in the basement, the problems are the usual ones: a weak run capacitor in the first hot week, a contactor full of ants, a condensate pump behind the furnace that quits and trips the float switch. Upstairs in a story-and-a-half, the complaint is heat, and often nothing is broken. Those rooms were finished without supply ducts, and no repair to the air conditioner will push cold air where there's no path for it.
Outdoor units here are often tucked into narrow side yards, against fences or near a neighbor's dryer vent. Starved for air, they run high head pressure, shut off on internal overload and cook their fan motors. June cottonwood on the fins adds to it. We clean what we can reach and tell you plainly if the unit would do better somewhere else.

It can. A condenser needs clear space on its sides to pull air in and open air above to push heat out. Squeezed against a fence or a wall, it recirculates its own exhaust, runs hotter and harder, and wears out capacitors and fan motors sooner. We check clearances on repair calls, and if moving the unit makes sense, we price that separately in writing.
Most likely the condensate drain. On humid days the coil above the furnace pulls a lot of water out of the air, and if the trap clogs or the condensate pump's float sticks, the pan overflows. In low basements the pump often sits on the floor behind the furnace where nobody sees it. Many systems have a float switch that shuts the AC off first, so warm air may be the first sign.
