How Long Does a Central Air Conditioner Last in Minnesota?
Carrier and Lennox put central AC life at 15–20 years. Why Minnesota's short summers help, what cottonwood, salt and hail do, and when to repair or replace.

Field dust and cottonwood fluff can choke an Arlington condenser by midsummer, and we clean and repair them for the same $79 trip charge we use in the metro, waived when you approve the repair. The written flat-rate price comes first, and the phones are answered every day from 7am to 9pm.
Central air came late to many Arlington houses. The ramblers and older two-stories were built with ductwork meant for heat, and a coil set on top of the furnace years later has to push cooling through runs and a single return never sized for it. That shows up as a coil that ices over on humid days, a blower straining against high static pressure, and far bedrooms that never catch up. We check airflow before assuming a refrigerant problem.
Outside, condensers at the edge of town and on farm sites pull in dust, chaff and cottonwood fluff, and a matted coil overheats the compressor. Older condensers tend to fail at the electrical parts first: capacitors, contactors and fan motors. On an older R-22 unit with a refrigerant leak, we price the repair and a replacement side by side so you can see both numbers before deciding.

Every AC repair call in Arlington starts with a $79 trip charge, waived when you approve the repair, and a written price before any work. Same prices in Arlington as in every town we serve. National averages (HomeGuide, 2026), not our prices: a condensate pump $100–$450, a capacitor $150–$400, a contactor $200–$450. See the capacitor cost guide and refrigerant recharge costs.

Maybe, but in Arlington's single-return ramblers, low airflow is just as likely. When the return is too small or the filter is loaded, not enough warm air crosses the coil and it drops below freezing. Turn cooling off and run the fan to thaw it, with towels around the furnace base. We measure airflow and refrigerant pressures to tell the two apart, since adding refrigerant to an airflow-starved system makes it worse.
It depends on the rest of the unit. A condenser that old almost certainly runs on R-22. A fan motor is a moderate repair, which HomeGuide puts at $200–$700 nationally, and it can buy a season or two if the compressor is healthy and the system holds its charge. If it's also low on refrigerant or the compressor draws high amps, we show you a replacement price beside the repair so you can decide.
