Wonderful service and reliable team! We have nothing but good things to say about Grant and his team! We originally had them in to do a furnace/duct cleaning and decided to also have them install a air filtration system on our furnace, as we are a house of asthmatics with pets! Grant and his team installed our filter wonderfully, and didn't hesitate to come out to help us figure it out on several occasions! We are very happy with this new filter system and notice a huge difference in our air quality! Thanks Grant!
