With the proper care and maintenance you should be able to get 15-20 years out of your a/c unit. Getting regular tune ups and fixing repairs before your unit breaks down completely will ensure you won’t be left without cool air when the Minnesota weather gets hot! Things you can do include, checking and replacing your filters on a regular basis. We like to set a calendar reminder for every month so we don’t forget. Also, make sure your outdoor unit is free from debris. If you live in an area with cottonwood or trees that flower and shed get out the garden hose and spray off the unit regularly. Lastly, call your cozy home experts if you need us!
