Great company from start to finish! We just signed up for The Duct Specialists annual AC/Heater maintenance plan, which is very affordable and received our first AC check-up (within a few days of signing up!). The technician spent over an hour doing what I considered an extremely through review of our unit and other related components. I am very pleased with the communication of the findings after the inspection and overall considered it to be a pleasant experience with this service provider. I highly recommend this company for their professionalism, appointment availability, affordable cost, and reliability.
