I chose Air Now to install a heat pump in my lake house. I have had the unit for a little over a year. My power bill has been reduced by approximately $30.00 per month, not to mention the propane gas I do not have to purchase. In addition, from the very first person with whom I had contact, everyone, and I emphasize everyone, at the company has been helpful, polite, and accommodating at all times. When you need them, they show up in a timely manner. When they schedule routine maintenance calls, they show up on time, if not early. If they are going to come early, someone always calls first. I can honestly say that this company provides the best service I have ever experienced.
