AC repair in Excelsior starts with a $79 trip charge, waived when you approve the repair. Humid July air off Lake Minnetonka exposes a weak system fast, and the fix is priced in writing before we start.
Cooling in Excelsior comes in more than one form, and each fails differently. Houses converted to forced air usually have a coil on the furnace feeding ducts built for heat, and with few returns the coil can ice over on a muggy afternoon. Radiator-heated homes that added cooling later often rely on ductless heads, where dirty filters, clogged blower wheels and blocked condensate lines cause most of the trouble.
The lake adds moisture to everything. On the south shore of Lake Minnetonka, July air carries enough humidity that a system with low charge or weak airflow stops drying the house before it stops cooling it, so owners tend to notice a clammy feel before warm air. Basements dug into damp ground add their own moisture load. We check charge, airflow and the condensate path together, and we'll tell you if a dehumidifier would help more than any AC repair.

Usually the condensate isn't draining. Each head catches water from its coil in a small pan, and it drains through a thin line that can clog with slime, sag or lose its slope, or run to a small pump that has failed. A very dirty filter or coil can also freeze and then drip as it thaws. Turn the head off, clean the filter if you can reach it, and call us to clear the drain and check the charge.
It can. A condenser pulls air in through its coil and blows it out the top, and if a fence, shrubs or a wall sit closer than the manufacturer's minimum clearance, it pulls its own hot exhaust back in. Pressures climb, the compressor runs hotter, and cooling drops on the hottest days. Trim plants back first. If the fence is the problem, relocating the unit is worth pricing at the next repair or replacement.
