I highly recommend Midwest! They installed a new furnace and A/C unit a few years ago. Things started off on the right foot from the very beginning with the consultative sales approach making sure we had the proper units for our house. After a number of years past (and our warranty had expired) we had a problem with our A/C unit - they came out promptly, identified the problem and replaced the unit. Afterwards they determined that the part was covered under the original part manufacturers warranty and immediately mailed us a check. That was only one of the many times we were overwhelmed with the high level of service and integrity that Midwest has!
