Annual furnace maintenance including humidifier and dehumidifier. All set for a Wisconsin winter. Miles was extremely helpful including explaining some things to watch out for in advance of downtime. Please send him again whenever I call for help. He is an asset for K M. Glad I signed onto a great service plan, worth the investment.

Ryan arrived at scheduled time and covered flooring before starting removal of furnace. They ran into some assembly issues that were quickly resolved. Once new furnace and air conditioner were completed I was taken through use of unit and new thermostat set up. Once they were done they did a very good job of cleaning up and removing floor protection and all old furnace / air conditioning components .

Jim did a great job explaining the service to be completed during the scheduled appointment. He was able to find a solution to not having a water faucet outside the home. Jim reviewed the details of the service he completed when done running standard testing for the maintenance of the unit. He even helped schedule the furnace check for later this year.

The customer service from when I called to when they completed the work the next day was excellent. Erik was prompt, polite, clean, and thorough. He explained the work he had done and explained why that work needed to be done. Our Mitsubishi wall-units look and work like new, and we are very happy with the service.

Patrick was a great representative of this business. He was very friendly, considerate, and communicative. He took the time to answer my questions, called ahead to let me know he was on his way, wore shoe covers to keep my house neat, etc. Everyone was friendly at the office when I scheduled this appointment also. I will call again for my next maintenance or repair appointment. Thank you!
