I had not done a service on my Fujitsu Mini split in almost two years. I called Comfort Solutions and had questions concerning maintenance and Steve talked with me for 15 minutes while on vacation on the mainland. Shortly, Bert came out to explain exactly what would be accomplished during the maintenance. I was encouraged to watch, ask questions and learn the process. Bert cleaned the two outside compressors and then cleaned each of the 5 units in my home. Bert was professional and extremely knowledgable. I have not been more impressed by any contractor who has done work on my home since moving to the Big Island. I now know what to look for and can do most monthly cleaning on my own and will call when more extensive cleaning is needed. Absolutely blown away by the great service. Mahalo Bert!
