The Cooling system is not working, so I contacted United Home Services. Ben's team responded soon. After a close investigation, the experts determined that it was the blowing motor in the furnace stopped working. Since the old system has been used more than designed life cycle, we decided to replace the Furnace. Ben's team is very professional and we don't need to worry about anything. After the installation, the team also tested the heating and cooling multiple times, and also provided some advices to extends the life of the equipment. The new furnace works great, thanks a lot!
