Just moved here from Illinois. Had to buy a new heat pump. Totally different from up north. CHA walked us through what we needed. They installed the next day and came back to clean all our air ducts. They repaired all breaks in our duct insulation under the house all with no extra charge. Great 5 year warranty including home inspections twice a year .Everyone was very professional and helpfull with our questions. Workers were on time and very efficient. we had a great experience with CHA and would highly recommend them. Our salesperson, Jason, came over when everything was done to check everything and to answer all our questions. He was great and did I not pressure us.
