AC repair calls in Big Lake homes
A Big Lake summer is humid, especially near the water, and the lake homes feel it most. In a converted cabin, cold supply air running through crawlspace ducts sweats on every muggy day, and the water soaks insulation and floor framing. If the AC also runs a little low on charge, the coil can ice up and then overflow its pan as it thaws. Ductless heads in cabin additions and lake-level rooms need their filters, coils and drain lines cleaned, or they drip and lose airflow.
Up in the 1990s and 2000s subdivisions, the calls are the usual ones for equipment that age: failed capacitors and contactors, a condenser fan motor, a slow leak at the indoor coil. The oldest units there may still run on R-22, which changes whether a leak is worth fixing. Along the Elk River, cottonwood fluff plugs condenser coils every June.

AC repair in Big Lake: questions
The ductless head in our Big Lake lake-level room smells musty. Can that be fixed?
Usually. A musty smell from a ductless head means mold or slime on the coil, drain pan or blower wheel, which stay damp through a humid summer. Washing the filter won't reach it once it's on the blower. We open the head as far as needed, clean the coil and wheel, clear the drain, and check whether the unit short-cycles, since that leaves the coil wet. The $79 trip charge is waived when you approve the repair.
The AC on our Big Lake subdivision home is original from 2002. Repair or replace?
It depends on what failed. A 2002 system most likely runs on R-22, so a capacitor, contactor or fan motor is still a sensible repair. A refrigerant leak is different: reclaimed R-22 runs $90–$150 per pound installed nationally, per HomeGuide, and the leak remains. At that point many owners put the money toward a new system, which runs $5,200–$9,800 installed with us. We give you both numbers in writing.
