I have been using Clean Air Heating and Air Conditioning for at least five years and they are a really great company! They are extremely responsive and prompt to come out when I need them, and their techs are very informative and helpful. The last time they did any work here, it was just the routine annual maintenance. I have been very pleased with them over the years. They are friendly and professional people, and I know I can count on them! I would highly recommend them to everyone!
