The world of duct cleaning can be murky. There are endless robotic humans calling from places far across the ocean - touting fantastic "specials". Ignore them all. We have been using Prestige, local and Canadian owned, for well over 10 years for our home and for some rental units we own. You get what you pay for. This is a top team of true professionals. Safety, cleanliness and efficiency are their game. They performed work yesterday at a town home where the tenant was complaining of poor efficiency from the clothes dryer. We did a vent clean out and Mark, the Senior Technician noted that the wire screen we had used to prevent birds entering was too small and the lint was clumping & inhibiting the exhaust. He suggested a wire "pest" cover which I purchased - problem solved. They also performed a duct cleaning service. I was delighted with the results. Do not hesitate to use Prestige. I consider them "tops" in this field. Their customer service is second to none& they are not shy to express appreciation for ones patronage. It feels good to be appreciated :) . Thank you to the entire team. I do not hesitate to most highly recommend this company to all.
