First, I am a prior customer, as I utilized Ductworks at my previous home, and was pleased with everything. During this visit, Matt, and I assume his trainee, Anthony, were absolutely lovely and very personable. Matt actually called to see if they could come EARLY, as they finished their previous job ahead of schedule, and that was fine with me. Upon pulling the dryer out from the wall and looking up the duct, and mine vents straight up to the roof, he took a picture, and it was completely clean! He then called his supervisor/boss to let him know, and after a short discussion, they did not charge me! That was very kind of them, as they could have charged me at least a trip fee. My house is only 3 1/2 years old, but having piece of mind that there won't be a fire due to clogged ducts is priceless! Thank you for your kindness and professionalism. I will be sure to contact them in the future and recommend them to others :)
