Be careful with this Company. We asked them to service our HVAC because it wasn't working. They did not fix the HVAC citing that we needed a new compressor and left within 15 minutes. They left no invoice. The company never contacted us again until we got a bill in the mail for $190.00. Mind you they never fixed it or asked if we needed it fixed. My husband called the company to complain and we got a $20.00 discount off the bill. By the way, a different Air Company came over about an hour after Mueller and Wilson and turned a switch on the HVAC. It started working just fine. This company&apos

The products and services Mueller and Wilson provide may be fine....but their vehicle drivers should seriously try to obey basic traffic laws. Driving into SA on I-87, (today) a Mueller and Wilson vehicle placed my family and I in serious danger, weaving in and out of traffic to Loop 410, and cut me off to get onto the access road. These are the company drivers Thomas J Henry, Jim Adler, and many other law offices base their practices on!!! The people on the roads are potential customers..:to either Mueller Wilson...or a law office!!!!!
