I called Air Pure for a quote on getting the ductwork cleaned. Robert came out to do the estimate and informed me that the plenum needed to be sealed were the ducts attach, otherwise dirt will continue to get into the ductwork. He showed me exactly what needed to be sealed with pictures and from what I can see in the attic. Robert is very thorough in explaining what needs to done and more importantly, why it needs to be done. I scheduled an appointment to get the job done, the ductwork was then sealed properly at the plenum and all of the HVAC ducts were deep cleaned and sanitized. This is a great company to do business with! From the manager to the technician, I had a great customer service experience and a job well done!
