We repair air conditioners in Eden Prairie 7 days a week, 7am–9pm, and put the flat-rate price in writing before any work. The $79 trip charge is dropped when you approve the repair. Homes backing onto Eden Prairie's creeks and wetlands tend to pull cottonwood fluff into condenser coils each June.
Eden Prairie's rolling ground and its creeks and wetlands both show up in cooling repairs. Cottonwood fluff in June mats on condenser coils, particularly on lots near Purgatory Creek and the lakes, and a matted coil pushes pressures up until the compressor trips on overload. Condensers on the walkout side of a sloped lot often sit at grade under a deck, where they recirculate their own hot air and collect leaves. We clean the coil and check clearances before measuring the charge.
Homes from the 1990s and 2000s that still run their original condensers fail in predictable places: a capacitor weakened by years of heat, a contactor pitted by thousands of starts, a fan motor with worn bearings. Larger houses with two systems need each one diagnosed on its own. In townhome developments, check that landscaping, fencing or a privacy screen hasn't closed in around the condenser, since the coil needs open air on every side.

Usually not. The lower level stays cool on its own, so it rarely calls for cooling, and a thermostat on the main floor is satisfied before the walkout air has been dried. An oversized AC makes it worse with short cycles. We check the charge and airflow first. The fixes range from a lower blower speed and a dehumidifier for the lower level to a second zone, depending on what we measure.
Not for long. Each system has its own condenser, coil and ductwork, so the working unit can only cool the floors it serves. Check the thermostat for the warm zone, its breaker and the disconnect beside that condenser, then call. We'll diagnose that system on its own and give you a written price for it, and we'll mention anything we notice on the other one.
