Your Go-to Team for HVAC Services in Grafton, WI

Mike has done numerous repairs for myself and my extended family. My A/C unit was out another contractor said the unit needed to be replaced for over $1,000 a mouse chewed a wire 6 years later still working great. $75.00.

Similar experience with my parents in-laws and sister all had "expensive repairs" fixed for pennies on the dollar from other contractors.
Does great replacement work when it is needed as well.

Furnace stopped working on a really cold day and called Mike and he came right out. Troubleshot it and was able to fix it quickly. Nice guy and great workmanship.

I can’t say enough about of service, professionalism and, honest person!!! I have reach out to a local company previously and BIG MISTAKE!!! I can’t stress enough BEST EVER!!!!!

Mike was really helpful to come in during night and repair our HVAC system. We were really worried being March Winters. Thanks Mike!

Woke up New Years eve morning to a chilly house. Called Mike, and he was here within minutes, diagnosed the problem, then said he'd be in touch as he left.He was able to get the part he needed and had our furnace up and running - with considerable effort - and missing half of the Packer game.Thank you Mike, you made our 24th Anniversary one to remember!

Mike helped us out in an emergency last fall, we were grateful for his knowledge and service! He just installed our new heating system and we are very happy with the work and service.

I have used Champion Air at my business for a very long time. The service is always excellent and the price is right! I strongly recommend using their services!

My business has been using Mike & Champion Air forover 10 years now. We call him up and consider itDONE !!!I do not have to say anything more !THEY ARE THE BEST !ROBERT

My AC went down on a 90 degree day. Mike came out in the morning and had me up and running by the afternoon. Super guy. Super service!

Everything was fine. Thanks for your timely response.

Very quick, affordable service. We called Friday afternoon and by Saturday morning our air conditioner was fixed.

Mike was very professional and cleaned up during and after completion of the installation
Our new energy efficient system is running well and we will look forward to our lower operating costs
He certainly know what he is doing and the experience of his background makes him the right choice

Mike came and diagnosed the problem and had my cooler back up and running within an hour. We called late on a Friday afternoon and he came after 5pm to help us out. Most people would have pushed us off to a Monday morning appointment.
Thanks for the great service!

Mike always responds promptly. His work is "top notch". Mike advocated, to the manufacturer for us, to resolve our furnace problem.
Thank you.

Mike was awesome, fast and on time. ChampionAir saved us when the part for our furnace had to be ordered and installed within 24 hours. All this while below zero temperatures outside became a major threat to our home, especially when the sun went down.

Chsmpion air does a great job

Over the years Mike has serviced and installed a broad spectrum of HVAC needs for our extended family. After another contractor failed to repair a boiler system in a rental unit; Mike with his expertise was able to properly service the system. Our son welcomed his grandparents into his home during a winter period when they needed proximity to a local hospital. A problem arose when my son needed a cooler environment (68 degrees) for his living on one floor, and the grandparents needed warmer temperatures (+90 degrees) on their level. Rather than incur the substantial costs of having a multi-zone system, Mike came up with a creative and substantially less costly solution! More recently our 30-year old AC unit was having difficulty providing enough cooling for our home. Friends had warned us about their experiences with the costs of upgrading their systems. We know our unit will not last forever, but Mike was able to repair the unit for substantially less cost to comfortably get us through this Summer and early Fall!

Even better than timely, Mike saved us when others wouldn't. Repair in a pinch. Thank you!

Everything was fine. Thanks for your timely response.

Arrived right on time, was very efficient and outstanding in all regards
