Brett came out and did a fantastic job of helping get my family set up with duct cleaning, a new pro size filter + housing and air scrubber for about 1/3 the cost of what I had anticipated. My 6 year old is allergic to dust mites and he found that my filter and housing were letting air through. The morning after install, I listened to the furnace kick in, which is usually followed by constant sneezing from her room. Instead there was restful sleep! Thanks Brett
