I performed a maintenance today on a Lennox system. All electrical components and safety switches regarding heating and cooling tested in range. Upon arrival and departure, the system was operating uninterrupted with an optimal temperature differential for both heating and cooling. I clean the outdoor condenser coil as it was dirty. I replaced the indoor air filter as it was dirty, filter size 20x25x5. We discussed a membership program, and I left the customers with a brochure. We would like to thank you for being a Cool Air Solutions customer! It was a pleasure talking with you. I hope to be able to do your maintenance in the future, Ryan Amat Technician
