I have always found Air Current Inc to be very professional in their approach to their work. I was not at home the last time they came out; my wife said they were very nice and friendly. I've been their customer for five or six years and I keep using them because of the quality of their work and the speed with which they respond. They also have good prices; it is a good value for the cost of their services. They came out recently and cleaned out the drain line for us and our HVAC is working well now. I recommend using them. They are always prompt and it's always a good experience when we use them.
