"Our 20 year old Armstrong has a failure last year which Droegkamp repaired. This year had another problem. Considering the age of the unit and the upcoming change in AC coolants we bit the bullet and purchased a new 2.5 ton Lennox unit. We got an appointment for an installation about 10 days away (it couldn't get here soon enough). The crew arrived at 8:30 on the designated. They removed the old unit, strung new hoses to the furnace unit, did a bit of duct fabrication, and were on the way to their next job by noon. They were very efficient, kept us in the loop about what they were going to do, and worked around piles of boxes that hadn't been moved in 20 years. They did a great job and they are now our regular HVAC choice."

"I've been using Kettle Moraine Heating for my annual furnace and AC tune-ups for a while now, and I couldn't be happier with the service. Khamya Little was professional, thorough, and took the time to make sure everything was running perfectly. It's always a relief knowing my heating and cooling systems are in great hands. The team at Kettle Moraine consistently delivers top-notch service, they're prompt, knowledgeable, and genuinely care about doing the job right. Highly recommend them to any homeowner looking for reliable HVAC maintenance!"
