AC & Air Conditioner Repair in West St. Paul, MN
West St. Paul AC repair is a $79 trip charge up front, waived when you say yes to the work, and the flat-rate price is written before we start. On an R-22 unit, a refrigerant leak usually tips the decision toward replacement.
AC repair calls in West St. Paul homes
West St. Paul's AC repairs come from two directions: houses and the businesses on Robert Street. On the house side, condensers range from brand new to well past 20 years, and the common failures are electrical: a swollen run capacitor that leaves the fan or compressor humming, a pitted contactor, a condenser fan motor with dry bearings. On a sound R-410A unit those are worth fixing. Recharging an R-22 system means reclaimed refrigerant at a premium, which changes the math on a leak.
Remodeled basements add their own call: a condensate line rerouted during the work that now sags or has lost its trap, and water shows up under the furnace. Airflow is the other house problem, since ducts sized for heat move less air than cooling needs. On Robert Street, rooftop units over shops and restaurants run long hours in the heat, and dirty condenser coils and worn belts are the usual findings.

AC repair in West St. Paul: questions
Our West St. Paul AC still runs on R-22 and has a leak. Is it worth repairing?
Usually not, unless the leak is small, easy to reach and the rest of the unit is sound. Reclaimed R-22 is expensive, a leak search can run long, and an R-22 system is old enough that other parts are wearing too. You get a repair price and a replacement price side by side before deciding.
Our West St. Paul AC runs all afternoon in July but the house won't drop below 78. What should we check?
Start with the filter and the outdoor coil; a packed filter or a coil matted with cottonwood can cut capacity sharply. Then have the system measured: refrigerant charge, capacitor and airflow across the indoor coil. Many 1950s duct systems have one or two small returns that can't feed the blower what the air conditioner needs. Adding a return often does more than refrigerant, which a leak-free system never needs topped off.
