They did a great job. Very friendly people to work with. I definitely recommend them to anyone who needs pluming done.
Brandon did a good thorough check on my furnace & air condition. He would take time telling me the condition of my systems & show me some meter numbers & point out some issues.

I could not be happier with KM HVAC. My serviceman is excellent and he appears to have a great company behind him. Don’t hesitate scheduling either KM or my serviceman.

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.
