Canaduct Duct Cleaning

I used them previously and have called them back,I have 2 furnaces as I have a large house, after renovations, we have major dust from drywall sanding, canaduct not only checks and cleans ducts, but also replaced my filters as they were extremely dusty ( although I had just replaced them 1 month ago, they cleaned dryer vent/bathroom fans/central vac area/humidifier filter/ as well as sanitized-was expensive but had to be done. Each section is priced out, so you don't have to do everything. Minimum cost would be $500.00 for your duct cleaning with one furnace.
