Testimonials What Our Customers Say “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.” – Ashley M. “Ronnie, Thank you for doing such a great job yesterday. You are truly an expert and we are grateful for your work!” – Janet & Ted T. “Thank you for your quick and accurate diagnosis of our air conditioning problem.
