From our salesmen Scott to our installers Eric, Johnny and Tim, we couldn't have asked for a more professional, knowledgeable team to do our AC replacement. From the beginning, Scott the made the whole experience easy with his knowledge and understanding of our needs and concerns. I would definitely recommend Waychoff's, Scott and our installers to anyone that is in need of either a service, maintenance or like us, a replacement of a aging and failing ac system in their home. Couldn't be more pleased with the whole experience and quality of equipment. Do yourself a favor, don't call anyone else but Waychoff's for and AC service needs.
The best way to know if your cleaning was effective is through improved performance of your HVAC system, ideally. You can have before-and-after pictures taken of the ducts (make sure they are of the intake ducts - the ducts that return air into your room), motor and coils. Another tip is smell – sniff the ducts before and after the work is done. Outside of noticeably improved performance, smell and visual evidence are your best indicators.
On the other hand there are many more air duct cleaning companies that will properly clean the air system and air ducts and use commercial negative air duct cleaning vacuums with at least 2,000 CFMs of vacuum power and utilize proper agitating tools to move the contaminates within the duct work to be captured with HEPA filters and contained by the air duct cleaning vacuum equipment.
