Good day!  A thank you note.  Recently requested service and Jon E came the same day.  Amazing.  Want to thank you.  Much appreciated.  Also want to say that your staff are very pleasant to deal with.  Jon E and I believe the last man was Mike.  Both were very pleasant and efficient.  Thanks!

Paul – Neenah, WI

We brought in MCM Air to evaluate upgrading the old gas furnace and air conditioning system in our 60 year old nonconventional house.  This house had been remodeled and added on to over the years.  Due to cutting corners with the central furnace and duct work, parts of the house had to add base board heating and a second attic mount air conditioner was required for the bedrooms.  Lastly, a gas wall heater was added to heat the finished basement.  Pete from MCM spent an hour with me walking through the possible options and carefully walked through his recommendations.  After only a couple days, he came back with a very professional quote that simply and clearly outlined the options we could choose from.  Once we gave him the approval, he came back with his installer, Eric, and once again spent at least an hour evaluating the installation options and planning the work.  When they started the installation, they brought a lot of help and quickly installed the new system over a couple days.  They cleaned up after themselves every day and ended the job with a very effective, clean, and smart installation.  Tapping into their extensive experience and with their goal of pleasing their customers, they exceeded our expectations.  Pete and Eric found a way to creatively add some zoning to our system, unblock an old heating vent, and add a return air vent that appears to have obsoleted out need for multiple rooms with base board heating, the need for the second air conditioning system over the bedrooms, and the gas wall heater in the basement.  It looks like one high efficiency system installed very effectively is going to replace all of the other stuff.  We would highly recommend these guys if you want a very professional installation by a team that really truly knows how to treat a customer right.


I would like you to know how pleased we are with Jake.  He is a very hard worker, stays on task, doesn’t even take breaks.  This day and time it is rare to see such a hard worker!

Thank you,

Steve and Marla

Jake and John,

Thank you for saving the day, when the handle came off the radiator and water was spurting everywhere!  You kept me calm, while I had one hand holding the broken handle in the fitting to keep water from gushing out and the other hand talking to you!  You’ve done amazing work in our old farm house!!! Much appreciated!!!

Vicki – Pickett, Wisconsin

Good afternoon Pete,

Your guys just left.

We finally got rid of the stress of a broken furnace!

Thank you again for making it happen today!

I would like to let you know that your guys are very polite and professional!

Also Tyler kept the mess to a minimum..if we weren’t here we would have not been able to tell that someone was in our basement working!!

We will definitely recommend you to everyone we know around here!

October 2021


I wanted to just send a quick note to say how pleased I am with the service I received this past week.

From the initial call to set up the appointment to the simple text message informing me the technician was on his way, I was impressed.

Your technician, Mike Mueller did a fall checkup on my Carrier Infinity furnace.  I was very impressed with his professionalism and thoroughness.  Mike was extremely courteous, he explained everything he did and what his findings were.

I work for a large company that is also a huge player in the service industry so I can see a good technician when I see one.

Great Job by all.

Thank you very much.


Hi Mike.  Just wanted to say how much I like the new HVAC system.  MCM made the whole process easy, from quoting, financing, to final installation and training of equipment.  I really appreciate the quality of product and install, along with the professionalism of your employees.  MUCH better experience than my last Carrier purchase from another dealer.  Thanks, Brian Oshkosh Wi

Just wanted to tell you how much I love my new Infinity system…worth every penny!!

Giving compliment.  Everything fell into place.  Everything is nice, neat, clean, they were very polite

Glenn  Fremont Wi.

Hi Pete.

I just wanted to drop you a note saying I’m very happy with your company’s service and install of our furnace and AC!

I the unit runs perfect and what a DIFFERENCE from our old unit.

You have a solid customer moving forward.


Good morning!  Just wanted to take a few minutes let you know how happy we are with the crew you sent.  Despite horrible heat and humidity, plus an incredibly difficult job, those guys kicked some serious ass all day long.  On top of that, the clean up they did…….by the time they were done it looked like they were never there in the first place.

Please take the time to let everyone at MCM Air know how happy we are.  Definitely will be suggesting MCM Air for anyone requiring heating and cooling in the future.

Thanks again!

Brian from Wild Rose, WI

Here’s a letter from the Peterson family from Winneconne, Wisconsin.

Dear MCM Air Team,

You completely exceeded our expectations.  We are so impressed with your service!  We’ve never used your services before, but a recent poor experience from another competitor prompted us to call you, and we are so happy we did.  Your sales rep, install guys and overall great service is appreciated and phenomenal.  Not to mention the fact that my husband and I no longer have to sleep on an air mattress on the concrete in the basement:)  Thank you!  New MCM Air customers for life.

The Petersons

Thank you so much for all the prompt service Friday. Please pass along to your awesome technicians. Doug

Doug K.

Good Morning Pete, I just wanted to comment on yesterday’s installation.  The boys did a great job.  I don’t think it could have went any better.  Eric is obviously a knowledgeable installer, and must be a good asset to MCM Air.  He goes about his work quickly, diligently and with good quality.  He was very informative on the equipment being installed and answered any questions I had.  My wife and I are very pleased with the new HVAC system.


Mitch did a great job for us!  Thank you.


Thanks for the excellent service.  Jake is a credit to your firm.

Hi Pete.  Just want to thank you for the great service!  The air conditioner works perfectly and is so quiet.  I thought i was hearing it the other night and I realized it was the neighbors.  I really appreciate your team!

Kathy B.

We are loving the new carrier furnace and air conditioner we had your company install.  Your workers did a great job.  Very prompt, polite and kept their work area cleaned up and neat.  Workers always answered any questions we had and we’re very helpful.  So glad we went with your company:)


Thank you so much for all of your hard work, knowledge and friendliness!  You all went above and beyond and we greatly appreciate it.

Excellent Product, Installation and Service
I had MCM replace the 40+ year old furnace and also A/C units at my house recently. They had to retrofit much of the existing ducting, and run new vents, etc. The installation and work performed was excellent. The installers did a great job from start to finish, and really knew their stuff. The WiFi thermostat installed with the Infinity System is great. The smartphone and touchscreen controls and very easy to use and keep the house a comfortable temperature when we are both home and away. I would recommend MCM to anyone looking for replacements/service


Very Pleased. Purchased Carrier furnace and air.


Awesome service, had them install our first furnace when we built and had no problem choosing who installed our replacement furnace.


Delivery was on time, and answered every question I had.


Fast installation and quiet
Our old central air conditioner was beginning to fail so I called MCM Air for an estimate. They were quick to schedule an appointment to do estimate and very competitive with their quote. The installation could hot have gone better and the installation gentleman was so nice, even to my dog! The unit itself runs so much less than my prier unit and I can tell that my energy bills are already less. Half the time it’s running I don’t even hear it! My last Rheem unit sounded like a plane was landing in my yard. Thanks so much MAM Air! Can’t wait until I am ready for a new furnace!


They installed a complete new system in a older home that never had air.  The service and installation were outstanding, great communication throughout.


Great Company!
We were replacing a Carrier zoned residential system. The professional who came out for the quote was extremely knowledgeable and helped us find the perfect solution. They were amazing to work with and I recommend them to anyone!!


Affinity Modulating Furnace and single stage A/C Installation
Replaced a 20 year old single stage furnace and A/C.  As is normal with MCM they did a great job!


Highly professional.  Very knowledgeable.


Just wanted to thank you for the extra effort you put in to get our air conditioner installed so quickly. It’s running great.  Your guys did a fantastic job.  We’ve been with MCM for many years and your customer service and knowledge is the reason.  We always recommend MCM when the opportunity arises.  Thanks again.  Ed and Tami.

Thoroughness, Customer Service, Quality.  Quickness of service on the initial call of the furnace not working, getting it running and then delivery and installation of a new replacement furnace within a week was greatly appreciated.

Thank you MCM Air for your service today with my heating issues. You remind me of days gone by with your respectful customer service, reasonable prices and promptness.

It is good to know that there is someone out there like you.


For services performed on July 17th.  Mitchell did a great job with the inspection and answering our questions.

Daniel G.
Neenah, WI

It is Saturday morning 1/10/15.  We experienced another example of MCM Air, service excellence. Woke up to a cold house and a problem with our furnace. Placed a call to the emergency contact number and of course the technician, Eric Z. answered the phone. He directed me through a series of preliminary actions that could have solved the problem, preventing the cost of a service call with no success. He stated he be would out in 90 minutes and arrived in 60. As is always the case with all the associates at MCM, he was courteous, professional and efficient.

Thanks MCM, I hold your company, staff and support is high.


Hi Pete,
Just a quick note to thank you for the quick installation of my Infinity Furnace Conditioning system.  Lance and Jim worked steadily all day getting everything done…and they did!  As I type this I’m enjoying the A/C.  I’m amazed at how quiet it’s running.  Being somewhat of an old “Geek”, I like the WiFi Thermostat too.  The guys cleaned up after themselves nicely and were courteous and polite.  I appreciate that.  I hope everyone at MCM Air has a Great Holiday Weekend!  Thanks Again.

Oshkosh, WI

Thank you very much! Pete is a very nice guy, plus he fixed our furnace.

Shiocton, WI

Hi Jon,
I just wanted to let you know that I mailed the check for our humidifier installation today.  I also wanted to share with you that the installer, Eric was wonderful.  He was prompt and courteous and patiently showed me everything I needed to know about the system.  I also appreciated that he was very tidy.  We are very pleased with MCM Air and the service we were given.  Thanks again!

Omro, WI

Dear MCM Air, Inc.
We just wanted to send this note of “thanks” to you and your employee Jon E.  On November 12, 2013, we placed the call to get service/help on our furnace.  We were gifted with quick “same day” service and a knowledgeable tech, who was not only thorough, cordial but HONEST.  He brought in his expertise and restored our heating unit with a minor fix and a new thermostat.  There was no pressure to upgrade our furnace and he made sure all was working properly before leaving to attend to his next job.  As we age, this gives us great comfort and security, knowing there are techs of this caliber to help us out.  He wasted no time getting the job completed.  We do give thanks for your company and will surely recommend your service to anyone who may need help with heat or air.  When we do upgrade, you will be the ‘go to’ company for our needs.  Your company comes highly recommended not only by our son, who is a contractor, but by other builders in the Oshkosh area.  Please share this note with Jon, along with the enclosed gift of gratitude, for his work ethic and honesty.  God bless and have a WARM and Loving Thanksgiving

To MCM Air,
I really appreciated you working around my crazy schedule and fitting me in to yours. Also, thanks for finishing the work promptly! A special THANKS to Mike and Lance; these two guys were extremely polite and always kept me posted on the project. They cleaned up as if they weren’t there.

Greg and Debbie

I just wanted to take a minute to let you know about the new system installation your team was on this past Wednesday. There was really nowhere to relocate the heat register in this bathroom. Anywhere in the joist cavity that the heat run was in, would have been “in the way”. Pete had a great idea by using the heat run in the closet, and running it into the wall so it blows into the bathroom. Pete made a potential bad situation into a perfect plan. My hat is off to Pete, and the rest of your team! As always, it is a pleasure to work with all of you!

Happy to report that my furnace is acting as it should – no more racket occuring.  Please tell John “thank you” from me.

Thank you so much for your quick response.


This is just a short note to thank your company and John in particular for sticking with, and finally resolving, the problem I was experiencing with high Carbon Dioxide levels in the furnace combustion chamber.  John’s perseverance, thoroughness and friendly demeanor were very much appreciated.  Thank you again.


The Church Council met last night and on behalf of the Council, I want to say thank you very much.  Like churches everywhere, we try to use our funds wisely, so we appreciate this consideration from your business.

Omro, WI

I want to let you know that Jane and I have been very impressed with the way MCM has worked with us starting from the thorough approach you took to making certain you properly quoted the business to Eric managing a team to deliver a high quality on time installation.  It will take some time for us to be able to determine how much we enjoy the new system but the work you guys did was truly exceptional.  You relocated the intake and exhaust, relocated gas lines, relocated the position of the furnace, provided MUCH more control of the system with the inclusion of 3 zones, and did everything else and more.  Sure, it was not cheap but I understand doing things the right way sometimes costs more than taking short cuts.

I would like to provide MCM an excellent review.

Thanks again for treating us like we were important customers.  Not every company does that these days.

Oshkosh, WI

Thank you!  Jake and Mitch were very professional.
