"In May of 2015, I had TOTAL AIR Install a new Lennox XC25cooling unit with a variable air handler with PurAir filtration system in my home. This month I had my 5th service check up done by Total Air and the tech that came asked when I got the unit because he thought it’s been within the year. I told him that his company did it in 2015. He was surprised sayting that it was like it was brand new. Thank you, Total Air, for your support and great service through the years."
