AC & Air Conditioner Repair in Mounds View, MN
Mounds View AC repair costs a $79 trip charge that's waived when you approve the repair, and ramblers with one central return often freeze the coil. The written price comes first.
AC repair calls in Mounds View homes
Air conditioning came late to most Mounds View houses. Mounds View's 1950s–1970s ramblers and split-levels were ducted for a furnace, often with a single central return, and the back bedrooms may have no return at all. Cooling needs more airflow than heating, so these systems run the indoor coil too cold. On a muggy afternoon, a dirty filter or closed bedroom doors can tip it into freezing, and you get warm air at the vents and water around the furnace as it thaws.
The condensers sit beside the house in small side yards, many old enough to have R-22 or a tired compressor. Electrical failures come first: capacitors, contactors, fan motors. Some houses still cool with window units, and adding central air there is its own project. Airflow and static pressure are worth measuring along with the charge, because in these houses a starved coil is often why the part failed.

AC repair in Mounds View: questions
The back bedrooms of our Mounds View rambler run 5 degrees warmer. Is the AC low on refrigerant?
Sometimes, but airflow is the more common cause here. With the bedroom doors closed and no return in those rooms, cool air has no way back to the furnace, so less of it goes in. Try the doors open for an evening; if the rooms improve, it's the return. We check the charge either way, and a transfer grille or a dedicated return usually closes most of the gap.
We replaced our Mounds View furnace, and now the old AC freezes up. Why?
Often the new furnace's blower isn't set for the air conditioner. Modern furnaces have a cooling fan speed that should match the AC's size, and if it's left too low, airflow across the coil drops and the coil ices. A new cabinet can also leave the old coil sitting crooked, with air bypassing it or condensate draining badly. We check the blower setting, the coil fit and the charge together.
