Exceptional as their service has been for years. We had two units installed working great for 5-6 years, (a lot of problems w/ our Lennox units, faulty cps. in both, under 10 years Lennox gave no allowance. We were blessed to find AC Pros, they replaced the Lennox units for American Standard that kept house cooler than w/ Lennox. Now we call them w/an old fan motor that we pretty much ran day and night wore out. They came right away and will finish installation today. Very nice people and very fair and caring.
