AC repair calls in South St. Paul homes
South St. Paul's air conditioning depends on how the house heats. Forced-air houses got central air added to the furnace years after they were built, and their calls are the familiar ones: failed run capacitors, pitted contactors, dirty condenser coils and refrigerant leaks, plus iced coils where a single small return starves the blower. A condenser made before 2010 may use R-22, which makes a leak repair costly.
Radiator-heated houses cool with window units or ductless mini-splits, and ductless systems have their own list: a clogged drain in the indoor head that drips down the wall, a dirty filter or blower wheel, and communication errors between the head and the outdoor unit. Where a yard slopes, a condenser pad that has settled out of level pulls on the refrigerant lines, and it can often be releveled.

AC repair in South St. Paul: questions
Water is dripping down the wall below our ductless unit in South St. Paul. What's wrong?
Almost always the drain. Each indoor head collects condensate in a small pan that empties through a drain line, and if the line clogs with slime, loses its slope or a condensate pump fails, water backs up and spills over the front of the unit. Turn the unit off and put a towel down. We clear and flush the line, check its pitch, and clean the coil and blower wheel so debris stops feeding the clog.
The condenser pad behind our South St. Paul house has sunk on one side. Does that matter?
It can. Manufacturers call for the outdoor unit to sit level, and a pad that tips pulls on the refrigerant lines and the electrical whip, which over time can crack a brazed joint or chafe a line. Water also pools against the low side of the cabinet. On a sloped yard the fix is a new pad on tamped gravel or an adjustable stand, and we can usually relevel it without opening the refrigerant lines.
