Reviews of local pros in Delafield, Wisconsin

My furnace went out on Sunday morning. They got back to me in less than 1 hour and had someone out right away. Needed a new furnace and they had it all installed and ready before noon on the next day. Customer service is absolutely amazing!!!! Never went to them before and they treated me like family. Also offered several finance options. So easy to work with and again I can't say enough about the amazing customer service. Definitely recommend kettle moraine heating to anyone.

To Whom It May Concern,

I am writing to formally request a review and clarification regarding the significant discrepancy between two estimates I received from your company for a Lennox furnace replacement.

I prefer to support family‑owned businesses, which is why I contacted your company after seeing your February 2025 television advertisement for a Lennox furnace priced at $3,999. Following that advertisement, I scheduled an appointment and received an estimate from your technician. He informed me that I would need a larger 70,000 BTU unit, which increased the total cost slightly to $4,145.00. He provided a written estimate for both the unit and installation. At that time, I explained—and the technician confirmed—that my existing furnace was still operational. My only motivation for replacement was its age (20 years) and my desire for a more efficient system.

On December 19, after seeing the same advertisement at the same price, I contacted your company again to move forward. However, the new estimate I received was $5,605.01—an increase of more than $1,400 from the original quote. The technician stated he had my February estimate and would update it, but the revised estimate included several additions that were not part of the original:

HCC16 charge of $499

Miscellaneous (non‑taxable) charge of $458

Miscellaneous (non‑taxable) charge of $299

These items were not included in the February estimate, which clearly listed a 70,000 BTU Lennox Merit ML296V unit without these additional charges.

Given that the advertised price has not changed and the originally recommended unit remains the same, I am requesting an explanation for the substantial increase. I would appreciate a detailed review of both estimates and clarification as to why the updated quote differs so significantly from the original.

Thank you for your attention to this matter. I look forward to your prompt response and a fair resolution.

Sincerely,
Kalim Khan

Greg was very professional & informative. He performed our annual furnace maintenance & installed a new smart thermostat for us. Upon completion, he answered all of our questions thoroughly.

First time we had Kettle Moraine Heating come and do a furnace tune up. Jacob did a fabulous job on my tune up. Very professional and friendly. Will definitely be using them again.

I had a very pleasant interaction with JJ from Kettle Moraine Heating. He was professional, friendly, and took the time to explain everything clearly. The service was prompt and stress-free, and I felt well taken care of throughout the process. I’d definitely recommend them.

Craig and his team were absolutely incredible! After weeks of delays and multiple technician switch-arounds from my home warranty provider (Cinch Home Services), Craig stepped in and saved the day. He installed our HVAC system in just one day, restoring heat when we needed it most.

The workmanship was phenomenal — and what impressed me even more was that after installation, Craig discovered issues in our dampers caused by previous technicians. Without hesitation, he fixed everything to ensure the system was working perfectly.

It’s rare to find someone so committed to doing the job right and ensuring 100% customer satisfaction. Truly top-notch service — highly recommend!

Dylan did a great job. Very professional, was kind enough to answer my questions as he was working on the furnace. A very nice person who was very knowledgeable and fixed the problem quickly. I appreciate the quick response and his great kindness and knowledge. Excellent experience. Thank you Dylan.

We have been using KM Heating & Cooling for HVAC for a couple of years and have always had great service. This was our first time engaging the Electrical division and the we were very happy with the service and work completed. Highly recommend.

Jess was a consummate professional. He had great advice, knew exactly how to diagnose and fix our issues, and was very knowledgeable. Kettle Moraine services are easy to navigate and communication was clear and frequent.

Very happy to have gone to Costco to be able to connect with such a great company! The entire team at Kettle Moraine was super responsive, great communication, and very professional. They provided a very timely experience. Our Sales Rep Peter was extremely knowledgeable and with his expertise was able to help navigate us to a system that would be good for our family. The team that came out to install our heating/AC were very professional, experienced and efficient. We are super satisfied with our experience and results. Thank you!

The service was amazing and immediate. My 16 year old furnace went out during these terrible freezing temperatures and it needed replacing..
I called Kettle Moraine Heating and they were able to get someone out within an hour to give me a quote.
Dan Glinske was professional and courteous and was able to get me a quote after completely examining our old system. Kettle Moraine Heating was able to replace same day and offered 24 month zero interest to pay for it! Great service ! I highly recommend them! Thank you to everyone there who made this a quick and stress-free experience!

I have had the greatest experience with Kettle Moraine Heating and Air Conditioning in my first home🙏🏾 Everyone is very professional extremely knowledgeable and very honest. Every dollar spent was worth every experience from the office staff to the installation team.

Everything went great. Im a new homeowner and kettle moraine has been awesome with a quick response during high demand times helping me and my family stay warm during the cold season. I have a old oil fernace and they have been able to keep it going at a good price. Its been a pleasure working with Dylan Rohde as he has been very professional and prompt every time I call. Thank you to him and his team. 👋

Kettle Moraine Heating & Air Conditioning came highly recommended by friends and co-workers and now I see why. Great communication about my appointment (Sarah) and from our repair man (Brett). He was very friendly, efficient, and took time to explain everything that was inspected and also fixed the clog that was causing condensation water to backup into our furnace. I was very impressed and will be using them if needed in the future. 5 stars and I would highly recommend!

Brent from KM Heating&Cooling was excellent. Professional, comprehensive and knowledgeable. This company must vet their people well because he was an A-player. We’ve requested him for service on A/C when weather warms up. Exceeded our expectations

Absolutely thrilled with Kettle Moraine Heating and Air Conditioning! Matt listened to my concerns and created a smart, effective plan for my bi-level with tricky ductwork. The install team—Regan, John, and Joe—went above and beyond, doing the job right and optimizing everything. My home now has perfectly even temperatures, and the work looks great inside and out. Excellent communication and truly professional—highly recommend! These guys know what they’re doing and they care about doing a job well done, which is so refreshing.

Pete and his assistant were both very polite and professional. They laid out the duct work/electric knowing what it should look before the job was finished. All wiring was properly routed and secured to mother board inside furnace. Pete properly tested humidifier and verified that everything was working. The area was cleaned up after the job was completed. A very professional install of the humidifier.

They did our new furnace install in 2022 and that was a great experience! Brent came out to replace our 25 year plus thermostat and was punctual, personable, and professional. I will recommend km heating to anyone who asks.

We had several jobs requiring an electrician. Kettle Moraine sent two top notch guys for all of our jobs. Joel and Neil worked tirelessly for four hours, and they knew their profession well. They were friendly, very knowledgeable patient and took enough time to explain everything to us. They wore booties to protect our carpeting and cleaned up after they were done which are things many tradesmen do not do. We were very happy with the work that they did for us.

Brian B from KMH&C did a wonderful job doing an inspection on my Furnace. He was informational and educated me on every step of his process as i was quite inquisitive and interested.

He was to the point, honest, and kind as if he were my neighbor. going above and beyond not trying to be a salesperson but telling me the honest work that would need to be done.

Kudos to Brian I cant praise him enough. Go with KMH for all your needs!

I just had the A-Team from Kettle Moraine Heating and Air Conditioning over today to install a new heating unit and AC unit. ALEC, Zack, Zack, and Dan did an outstanding job with the total installation! They all were very nice, professional, and knowledgeable! They were very helpful in answering all my questions and explaining everything I needed to know! I couldn’t ask for a better crew doing the job! Quality company and work crew! Thanks for your service!
