Todd came by my place for a cleaning of my house's ducts. He took took his time to go around the house for inspection before he started.
He found my house's central vacuum and an HR unit. He advised that those could also be cleaned out. I only opted in for the additional Central Vacuum clean in addition to the duct cleaning work.
I heard the dust and rocks going through his large orange pipe. I saw the dirt, pet fur, and dust piled up in my ducts. Todd cleared it all out over the course of several hours: from 10:50 arrival to 3:00 leave.
At the end, Todd took time to walk me through the perculiarity of my Central Vacuum unit and how to take care it. Plus how to take care of an HR system.
It was more costly to hire Todd and team but it was very well done as it left me with confidence that my house has clean ventilation!
