Finding Heating And Cooling Repair Minnetonka

I have been having issues with my central air in my home. It is starting to get warmer out and I would like to use it but it doesn't work. I have to have it refilled yearly because it leaks. I hired someone last year to fix it. It worked all summer last year, but now it isn't working again. I have been searching online for heating and cooling repair Minnetonka. I have found several companies with good reviews, but I am looking for the one that costs the less. I have called different places and will have to call a few more to see if I can find a cheaper price before choosing one.
