Qualtech Heating and Cooling worked on the ducts that needed to be repaired and replaced at a reasonable price and gave me a senior discount. I switched over my heating contract and they came out and serviced in September, doing a nice job. This was my first time using them, and they are scheduled to come out twice a year, once in the fall, and once in the spring. I was very pleased with their work on heating and air conditioning. They did work initially in July, which was when I switched my heating contract over to their company. I am looking forward to them coming in the spring to work on air conditioning. I would definitely recommend their services.
