I appreciate the work you did! 6/04/2015 Dear Houk AC - Just wanted to drop you a note and let you know how much I appreciated the work you and your guys did yesterday. They spent about 11 hours at the house and did a fantastic job. They were incredibly polite and professional. The house cooled quickly and was extremely comfortable. My next call is to Lennox to see about having Houk do the warranty work on the upstairs unit. Can’t wait to replace that unit as well. Gregg S, Plano, 4/30/2015
