Hear from our customers

“We had a high efficiency Lennox unit installed last year and couldn’t be happier. The installers arrived on time and worked quickly to ensure we had cool air in a matter of hours. They also took the time to explain our new thermostat. We have recommended Custom Air to all our friends and family.”
