Our AC was working but not cooling, so we have engaged Superior Plumbing and Heating for diagnostic and repair. Since replacing some electrical components did not help we agreed to buy and install a new AC. Two days later two technicians showed up with a new AC unit. They worked very efficiently - they dismantled and removed the old AC, and while one of them was working in a furnace room, another one was working on AC unit outside. When installation was completed AC was tested and proved that works well.Technicians behaved politely and professionally. We are very pleased with the job done and we would confidently recommend this company for HVAC service.
