Our AC repair visits in New Germany carry a $79 trip charge, waived when you give the go-ahead, and the flat-rate price is in writing first. We take calls 7 days, 7am–9pm. Story-and-a-half houses here put bedrooms under the roof, where a struggling air conditioner shows up first.
Most central air in New Germany's older houses was added to a heating system designed decades earlier. The coil sits on the furnace in a low basement, sometimes on a short, improvised plenum, and the condensate line runs wherever it could. A trap that dries out or plugs spills water onto a basement floor that may not have a drain nearby. Upstairs, bedrooms under the roof slopes get small ducts and plenty of sun, so they warm up first when the charge is low or the blower is weak.
Condensers on the farms around town work in dustier air than a city lot. Field dust in late summer and cottonwood fluff in June coat the fins, pressures rise, and capacitors and contactors wear faster. With the power off at the disconnect, a garden hose run from the inside out clears most of it. We handle the capacitor, contactor, fan motor and refrigerant work.

In summer the AC coil on top of the furnace pulls water out of the air, and it has to leave through a trap and drain line, often into a small condensate pump. In low basements the line is sometimes run flat or even uphill, and the trap plugs with algae. When the pump's float sticks or the line clogs, the pan overflows. We clear it, re-pitch the line, and test the pump and any safety float switch.
Most often a weak run capacitor or a seized condenser fan motor. The capacitor gives the fan and compressor the kick they need to start, and heat and age wear it down. Switch the thermostat to off so the compressor stops straining against a dead start, and call us. On farm units we also check the control box for wasp nests and debris, which can cause the same symptom.
