"My neighbor and I looked into ductless heating and cooling and noticed that Air Tech had great reviews and I know why. We both hired Air Tech after interviewing other companies. The work was completed on schedule. The technicians were courteous and respectful and spread cloth on the floor in the rooms they were working. Anytime I had questions they were more than willing answer them. Even the secretaries in the office are great. I would highly recommend Air Tech."
