Paul Hannah is an excellent technician, friendly and professional. He knows his HVAC systems, and even when he encounters something unexpected, he seems excited to solve it. The Duct Cleaning Specialists is a small company, not a franchise, so you get the guy you spoke to on the phone when you schedule a cleaning.
My house is a 1920 era three story storefront, and it always has a surprise or two for contractors. Paul found the furnace humidifier had never been cleaned, and disassembled and cleaned it, telling me how to maintain it properly.
He noted that an earlier duct cleaning company (hired by the previous owner) had not cleaned the return ducts, and he made sure all the duct work was cleaned thoroughly.
He also cleaned my dryer ducts and replaced a poorly functioning vent.
The biggest surprise was his discovery that the top floor air return had been used as a garbage chute by the previous owners. Five feet of paper,cans and other refuse was piled on top of the return vent opening. Paul improvised a extremely long vacuum hose for this problem he had never encountered before, and lifted out the pieces a few at a time.
Despite the job being much more difficult that Paul had quoted on, he stuck with his original price and even sold me some filters at far below Home Depot prices. he left the house completely clean upon finishing the job.
I absolute recommend Paul to anyone who wants to breathe better, and know what's happening with their HVAC systems.
