AC repair calls in Saint Paul homes
Cooling in Saint Paul splits two ways. Houses that got forced air when their gravity furnaces were converted usually had central air added later, with the coil stacked on the furnace in a low basement and the condenser squeezed into a narrow side yard or tucked by the alley garage. Tight spots cook a condenser: it breathes its own hot discharge, the coil packs with cottonwood from trees along the Mississippi and the big parks, and capacitors and fan motors give out in the first run of 90-degree days. A lot of those add-on systems still run on R-22.
Radiator houses on hot water or steam have no ducts, so their cooling comes from ductless mini-splits or small-duct high-velocity systems with an air handler in the attic. Those fail differently. Condensate lines clog and drip down a plaster wall, indoor heads load up with dust, and an attic drain pan can overflow into a bedroom ceiling during a humid July week.

AC repair in Saint Paul: questions
The ductless head in our Saint Paul radiator house is dripping water down the wall. What's wrong?
Most often the condensate drain. The head collects water from the air as it cools, and if the drain line is clogged, kinked or has lost its slope, the water backs up and runs out the front. A head that isn't level does the same. If the drain relies on a small pump, that pump may have failed. A dirty coil can also ice and then drip as it thaws. Shut the unit off and we'll trace which.
Our condenser sits in the narrow gap between two Saint Paul houses. Is that why it keeps breaking?
It can be. A condenser needs open space to pull in air and throw off heat. Wedged between two walls, it recirculates its own hot discharge, head pressure climbs, and the capacitor, fan motor and compressor all run hotter. We check pressures and clearances on the repair call. If the spot is the problem, moving the unit is usually cheaper to do when the system is replaced than as a separate job.
