I'm so grateful for Sierra Air and Wayne E!!! We purchased a 22 year old home and knew the A/C was old so I wasn't surprised when our house wouldn't cool down this week. My husband contacted Sierra Air and they scheduled a technician to come out the next day. Wayne was so friendly and examined all the equipment. He explained to me everything that was going on with our system. He gave us options from just adding coolant to repairs to a new unit. He wasn't pushy about selling us a new unit but did show us pictures of the system in our attic and it is pretty clear our unit needs to go see Jesus. The experience made it easy to trust them and we will be purchasing a new unit through them soon.
