i have been using Polar Bear for any A/C repairs for about 20 years.As I keep cars a long time (my current ride, in 2020, is a 2004) I want the repairs to be done right, and only once. I get that from Kevin and crew at Polar Bear. My latest need, an AC compressor, was done during this Covid-19 period. Kevin sanitized everything he or I touched, from the ball point pen on the counter, to the car's door handle and key ring. (Almost) needless to say, both car and I are running quite well, after our Polar Bear visit. My air conditioner now has a three year warranty. I wish I had one for myself.
