I called up Air Current Inc. and had them come out to give me a quote. The technician came out after that to service our heat pump and everything turned out excellent! He was very knowledgeable, personable, and very friendly. He took the time to go into depth about the heating system and explained everything to me thoroughly. I really appreciated that. It was so easy to set up an appointment with their office so I am definitely going to recommend using them. It was an excellent experience to work with them.
