I am asked “How often should I have my ducts cleaned” and “How much should this service cost ” ? Our customers know we do not provide this service and feel they can get a unbiased response. Well, I am pleased to lend my 2 cents. #1. I feel that all ductwork gets dirty and is filled with construction debris during the home’s construction. I also feel if there has been remodeling done, a thorough duct cleaning is in order. As far as how soon thereafter, it depends on the home, the number of occupants and number of pets. Also, the filtration system on the furnace plays a huge role. A 1″ filter allows about 90% of the dirt to pass through it and into your ductwork, while a Hepa-filtration system captures about 99% of all airborne particles. Having said all of that, I would be shocked to see a home which would require a second duct cleaning prior to 5 years later.
As far as cost, you should expect to pay at least $200 and expect the process to take a minimum of 3 – 4 hours.
We have had great luck referring a Company called Ductz to help all our customers and know they do an incredible job for a very fair price.
