“Ten stars for the Bethke crew. We had our furnace replaced in January and the AC last week and we are extremely satisfied with both units. Vickey is amazed at how good real air conditioning feels. TY. From our initial contact with Jeff to the installation techs, Matt, Patrick and Cory, we cannot say enough about their professionalism and knowledge of the process. Just good solid people to work with. We highly recommend Bethke and look forward to having them maintain our investment.”


“Mike and John were here today to repair my central air and do a tune up of both that and the furnace. They got the air running smoothly and had the needed parts in the truck. They were efficient, thorough and communicated kindly and well. The price was very reasonable.”


“Great company with friendly, knowledgeable staff who do good, honest work in a timely fashion. They don't seem interested in upselling us on anything we didn't need and actually talked me out of going with a more-expensive option for the AC since it wouldn't offer much benefit in my house. They've earned a customer for life with their work.”

Your workers treated us like we were the most important customer they have ever had. The technicians went out of their way to explain our options and to make sure we understood all costs before going forward with the work. They were extremely professional and considerate. We were very impressed with their work and price and would use BETHKE for any of our heating and cooling needs in the future. Thanks!

Brad & Angie, Verona

We are so thankful for BETHKE's timely service when our furnace broke in the middle of the night on a Saturday. The temperature outside was -1. Once the call was made to BETHKE, within an hour three space heaters were brought to our house and a new furnace was decided upon for Monday. Our house was back to normal by 1 pm Monday as if nothing had happened. It was truly an awesome display of customer service and professionalism. Thank you BETHKE for making such a stressful situation calm and warm.

Deb, Madison

We appreciated the time and attention Jeff gave to us when he came to give us an estimate. He was thorough and aware of the age and integrity of our home. We liked that he gave us options and didn't seem to pressure us into a decision. Your technicians (Dan & Joe) were a pleasure to work with. They were at our home for a week. They were professional in all respects. They treated our home with utmost respect and did a wonderful job. We couldn't be happier with any aspect of the sale/install. The products are quiet and are keeping the house very comfortable in this awful heat and humidity. Thank you!

Dave & Chris, Madison

I had my furnace serviced and the ducts cleaned. The technicians were on time, very polite, and explained to me all of the work that they were going to do. They went above the minimum service, making sure that everything was clean and also teaching me how to maintain parts of the system myself by changing the filters, etc. They minimized mess, and were aware of my pets and respected my home and my time. I couldn't be happier.

Lenora, Sun Prairie

Over the years I've come to trust and rely solely on BETHKE and Greg G. to take care of the boiler in autumn and the air conditioner in spring. Greg is completely thorough, cleaning “inside and out” and educating me along the way about settings, how things work, efficiency, etc. My equipment is outlasting the years I expected. And I'm always comfortable. It pays to “go local.” Thank you!

Helen, Belleville

I got a total of four quotes on our oil to gas furnace conversion. Jeff from BETHKE spent the most time with me explaining our options and what worked best for our heating needs, not what was best for the company. He even brought up some things that other companies hadn't even mentioned when meeting with me. We were impressed with how this attention to detail continued on to the installation process. The crew was on time, courteous and cleaned everything up. We appreciated the excellent service and are now enjoying our new furnace.

Megan, Madison

Your crew did a great job on my new steam boiler. Very professional. Thank you so much.

Gregory, Middleton

Mike came out to do a dryer vent clean out and confirmed what I had thought – that the dryer vent in place was not up to code and couldn't be cleaned. As a mom of three kids, I needed to get my dryer operating (safely) and Mike came up with another option to re-route the dryer vent since the basement is finished and there was very little access to fix the old one. He was back the next morning and by 10 a.m. I had my dryer back – only better – it now takes half the time it was taking to dry clothes! Thanks for your great service!.

Angie, Sun Prairie

We have used BETHKE for about 4 years for furnace, A/C, and duct cleaning work. We are always very pleased with everything you do. This includes promptness in arrival, knowledge of the technicians, installation work, keeping the work area clean (especially after completion of the work), maintenance work, explanation of charges, quality of all work we have ever had done, and even that the prices charged are reasonable. (We have done comparison shopping, and keep coming back.) When we call BETHKE, we just know the work will get done as scheduled, without hidden costs, done very well, and without surprises in results. We recommend BETHKE to anyone.

Dennis, Madison

Jeff was extremely knowledgeable. He presented many possible approaches and helped narrow our choices to finally select a system that best fits our needs. He presented a detailed estimate, fielded all our questions and concerns, and problem solved ways to stay within our budget. The installation team began and ended within their estimated time frame and kept us appraised of progress. When finished, they thoroughly cleaned work areas and made sure every detail was covered before they called the job complete. We recommend the high-quality, skilled professionals at BETHKE Heating & Air Conditioning.

Susan, Madison

When the old furnace in our new home stopped working on a freezing cold Sunday in January, not only did BETHKE lend us a couple of space heaters to get us through the weekend, they also made sure the repair was done a.s.a.p. on Monday. Now we have a regular maintenance plan in place for both our furnace and our central air conditioning. When the office staff calls to schedule our check-up appointments, they are always so friendly and accommodating. And all of the servicemen – some of whom are now very familiar faces – are extremely knowledgeable and helpful.

Whether it's routine maintenance or a heating emergency, we rely on BETHKE. Now, and for almost 20 years!

Laurie & Jeff, Madison

Service was great, timely, and no pressure. We were able to make the costly decision to replace our furnace with good information, no pressure, and the willingness to go whichever route we chose. We were able to have a new furnace installed the same day, and it was done professionally with the guys going the extra step to ensure cleanliness and respect for our home. Thanks so much.

Kris, Verona

I definitely called the correct company to do my install. Despite the difficulty of the job – not your typical install – everyone was very professional and friendly. I never felt that they rushed through the job, and I'm very happy with my new furnace and a/c. Clean up was great; you wouldn't have know they were there – no tools left behind either!! Give Joe, John, and Dan a thank you again from me. They are very good at their jobs!

Anita, Madison

Mike went ABOVE & BEYOND his duties and was very dedicated to doing his job well. We just had a baby (6 weeks old) and he – Mike – was so careful in putting tarps down over the baby stuff so dust wouldn't get all over it. We are so very happy with our decision to use your company's services and will definitely call again next time we need our ducts cleaned. Please pass the word on to Mike!

Rachael, DeForest

BETHKE technician arrived when he said he would. Workmen have always respected our home and personal items in the home. I am aware that I am a very particular homeowner. I am happy to say that the BETHKE men are usually neat and do a good job cleaning up at the conclusion of their work. Oh yes… I can honestly say that they are a friendly lot.

Bob, McFarland

All in all, working with you was excellent. Communication, honesty, and professional workmanship were outstanding. I would also add that the two crew leaders I dealt with – John (for air conditioning) and Jason (for furnace replacement) – were notable for their hard work, friendliness, and intellegent use of their skills.

Steve, Madison

It's worrisome when you need to find a new heating specialist - who can you trust? I chose BETHKE for a furnace check-up and from the first call to the friendly receptionist I knew I was in good hands. The technician arrived on time, was friendly, skilled, and cleaned up everything when he was done. I was so impressed and am relieved to have found a new heating/cooling home.

Frannie, Madison

You guys are the best! This is the second project you've done for us and both were top notch! BETHKE's employees are great to work with and know their stuff. Everything's up front and wonderful. Will always be suggesting BETHKE when people ask us about our new furnace!

Lisa & Tom, Madison

It was great! Mike came over to do a duct-cleaning, and was incredibly thorough. I had only had this service done once before, at another house and by another company, and your system is much better. It's great to have 54 years of dirt and dust cleaned out of the duct work. Thanks, Mike!

Rosie, Madison

Two years ago we returned home from a trip to find a waterlogged furnace and the house temperatures in the low 30's. We called BETHKE (it was not their furnace but we could not reach our normal service provider). BETHKE was here within a half hour with large room heaters. Within a day the old furnace was removed and the new efficient furnace had been installed. Service was superb and continues to be to this day.

Bruce & Marsha, Madison

Your service was on schedule (very nice), your installation was well planned and aesthetically pleasing to my spouse & me both, and importantly, the whole BETHKE crew was enjoyable & welcome in our home. They are incredibly thoughtful, efficient, & creative workers. They left the site inside & outside cleaner than they found it! Well done!

Harry, Madison

We've now used BETHKE for a new furnace, a new A.C. and finally, a duct cleaning. In every case the technicians have been professional, very neat, and conscientious. Any service issues have been handled quickly and to our satisfaction. We think BETHKE is great! We're fans.

Bob & Sara, Madison

Service technicians were professional, courteous, prompt, and neat. Good staff! Very respectful of working clean with drop cloths, etc. I have used BETHKE ever since I had a bad experience with [other company name] 20 years ago. I would not hesitate to give BETHKE a wonderful referral. Its sales and support staff have always been very friendly, helpful, and professional. Thank you for your prompt and fair service.

Dan & Sue, Verona

We really appreciate all the assistance given to us by the BETHKE staff on this project of installing a gas furnace in our home. Julie, Michelle, and the two Jeffs were helpful and responsive. They always took time to answer our questions patiently and completely. Our praise & appreciation go, of course, to Jason & Mark who actually installed the equipment. They were skilled, thorough, and efficient as they went about their work. In terms of customer service, they were friendly and reliable and gave helpful recommendations when decisions had to be made. They valiantly tried to explain the system to us. Thanks to all of you for your fine work. And a special thanks to Jason & Mark.

Don & Blanche, Madison
