AC repair calls in St. Francis homes
The typical St. Francis AC is a builder-grade condenser from the 1990s or 2000s, or the first replacement for one. The failures are familiar: a swollen run capacitor, a contactor with pitted points, a condenser fan motor that stopped, and eventually a refrigerant leak at the coil. The refrigerant decides a lot. Units installed before 2010 may run on R-22, whose production ended in 2020, so a leak there usually brings a replacement price along with the repair price.
Near the Rum River, cottonwood fluff can blanket an outdoor coil in June, and muggy evenings keep the system running long after sunset. Inside, a condensing furnace's drain often shares a pump or floor drain with the AC coil, and a clog there puts water on the basement floor. We check the filter and airflow before we touch the refrigerant.

AC repair in St. Francis: questions
Our St. Francis AC was installed around 2005. Is it worth recharging?
Only after the leak is found. An air conditioner needs refrigerant only when it's leaking, so topping it off just delays the next call. A 2005 unit may use R-22, which is available only as reclaimed refrigerant now, or R-410A, which can still be serviced normally. National cost guides such as HomeGuide put a leak search and repair at $200–$1,500. At 20 years old, a coil leak usually tips us toward replacement.
Water shows up by the furnace in our St. Francis basement whenever the AC runs. What's leaking?
Most likely the condensate. The AC coil drains through a trap and a line to a floor drain or a small pump, often shared with a condensing furnace. Algae clogs the trap, the pump's float sticks, or a hose slips off, and the water lands on the floor. Switch the system off at the thermostat. We clear the drain, test the pump, and add a float switch that stops the AC before water spills if there isn't one.
