I had a great experience using Prestige Duct Cleaning to clean the ducts, furnace and AC unit including its fan. I recently renovated my house and there were a lot of dust, debris and dirt in the ducts. Especially construction dust which is much heavier and sticky. Chris and Cooper (I hope I got the names correct) showed up on time, were very professional and knowledgeable, and guide me through all the work and steps. They ensured that the house remained clean and undamaged during the whole process. They made sure everything was back to normal and covered all the access entries in the ducts. They even opened my humidifier system and changed the filter which had not been done by the contractor as promised. I could not be happier with the result, and will recommend them unreservedly.
