HVAC reviews in Seymour, Wisconsin

Brian & Pat took their time explaining the different options we had for new furnace & A/C. They fit us in immediately. Nolan and Westin worked efficiently and were very pleasant and knowledgeable.

Thank you Diedrick’s Heating and Cooling for the wonderful service you provided during our years-long remodeling project. Even when our old furnace quit in the middle of the night in the cold of winter, you were right there to help us stay warm. You have helped us update this old farmhouse, and we are very appreciative of your service, always friendly, always available. Here’s our hope for your future success. Thank you so much for working with us!

My furnace was running, but not blowing heat. I called & Brian was at my house within an hour. He had the part needed & my heat was fixed within 45 min! Diedrick Heating & Cooling very professional & kind.

Diedricks installed our new furnace and we are completely satisfied with not only the quality of their products but their fast and friendly customer service. They now offer (and we subscribe to) their annual maintenance program payment system. No need to worry about a writing a check or dropping off a payment; they take care of it automatically in monthly installments throughout the year so there isn’t any worry. I would recommend these guys to anyone!

Brian and his team of technicians and installers always do an excellent job. I always feel comfortable with them coming to my home to work on my heater and air conditioner. They have been very flexible when I had some projects going and I needed them to come out to disconnect/reconnect equipment and needed advice. I have been a happy customer of theirs since I bought my house at the end of 2019!

We called them, because the temperature in the house got down to 50 degrees. Well, the furnace quit. The gentleman came out. Got the furnace going. He was honest and told me he really couldn't tell me why it quit. If it happens again give us a call. Well, it happened later that evening. My son came over and checked it out. He gave them a call. My son got it going. Well it wound up being the thermostat. Only one service charge for him coming out twice. And when I got the bill in the mail. Well, I was not expecting it to be such a reasonable price. My son was happy with it too. He knows who to call if needed.
I think it was a job well done! Thank you So Much!

Through a different company, I was quoted over $1200 for a part replacement on our furnace. Brian and Weston came out and were able to replace that part and another for almost half the price! Very honest and trustworthy people. I know who I’ll be sticking with for the future.

We had a great experience with Diedricks. They were incredibly trustworthy and professional from start to finish. Communication was excellent, they explained everything clearly and made sure we understood our options without any pressure.

The technicians were all very knowledgeable, arrived on time, and completed the work efficiently. On top of that, everyone we interacted with was friendly and easy to work with, which made the whole process smooth and stressfree.

It’s refreshing to find a company that truly values customer service and takes pride in their work. I would absolutely recommend them to anyone needing heating or cooling services!

Randerson installed the ac unit on 9/21. It did not run till April of 2022, It did run all of 2022. It stopped, would not start on the first week of July of 2023. Randerson came to the site about July 11. Took off a panel on the ac unit and a wire had completely fallen off. Just fell off the connection. This thing ran a total of may be 6months. Of course the warranty against shoddy workmanship ran out sometime in the winter. So today I paid the bill for the 2 min repair job, but randerson heating and cooling will never see another job from me.

Randerson H&C has helped me with a few HVAC issues including a brand new furnace. Always punctual and helpful. Good honest business. They are willing to work with their customers to keep them happy.

We had issues w/our furnace (11/2023) that the gas heat would not go on some times. I called Randerson Heating and Cooling and they came out same day. Of course the furnace worked when they turned it on. He talked to my husband about options of replacing a part or replacing the unit. My husband and I discussed it and decided to get a new furnace. Our home is 21-22 years old and knew we were on borrowed time. They told us to call if we needed heat over the weekend until they get the unit and they would come back to give us heaters, etc if needed to keep the house warm. We didn't need to as we have a fireplace that would work. The other thing they talked about was if we wanted to replace the A/C as they had to do some duct work and if we were going to get a new A/C more duct work would be needed when they replace it. So, they wanted to know if we wanted to do that right away or wait (but it would save $$ if they did it now while they were in the midst of the job). We decided yes and they came back within the next week to get it all done (waiting until spring to replace the A/C). Terry is the girl that answers the phone, billing, and schedules. She was so helpful and said that there was a limit on how much you could put on your charge card w/out a surcharge (I was over), but if I were to make it in payments it would be the same amount and I could pay for it that way and use my charge card (I get points and it would be sustantial savings). I think they are extremely professional and still small enough to make you feel like welcomed family member. I would definitely recommend them.

Air conditioner wasn't running effectively, so we called to have a tech come look at it. After identifying the issue, he alerted us that he could help it run this year, but it wouldn't last a very long time beyond that.
Fast forward to winter, and we shopped around for a new furnace (22 years old) and air conditioner. After comparison, we decided to go with Randerson.
Nick and his staff were very informative, not pushy and worked with us to get a system that will do the job without overkill. He offered options on the system that we could add, but wasn't hard selling to get us upgrades. Both were installed when promised, and we are living in comfort.
If you are in need of either service or opinions, I wouldn't hesitate to give Randerson Heating and Cooling a call.

We definitely recommend Randerson Heating Cooling! Tyler keeps our boiler and AC running great. The service is prompt and the price always seems fair! After I paid my invoice I received a hand written “thank you for your business” card, we were very taken back by that gesture, gone are the days where a business actually shows appreciation for your patronage!

My furnace went out Friday afternoon. I got home from work at 4:03 and it was 64 degrees in the house. By the time my son and I took the panels off of the furnace to try and troubleshoot, it was about 5:30. Everyone had closed. There were some 24 hour places listed but some of them did not answer their phones. After calling around, no one either had the part, would sell me the part, or would tell me if they even had the part. I called Randerson around 7:00 on a Friday night. A man answered and I asked him if he happened to have an inducer motor that he would sell me. I gave him the model number I needed and I could hear him looking through boxes. After a few minutes he said he did have one and would sell it to me. He waited for me to show up and I was 30 minutes away. He sat in his van WAITING FOR ME! I showed up and received the correct part and was able to go home and restore heat to my house in 30 minutes. Randerson, if this gentleman is an indication of the service all of your employees give, your business is truly a CLASS ACT!

We had Randerson install a mini-split unit in our home. We had a great experience with them from start to finish. We were given an accurate quote with clear information and expectations. The men who did the install were honestly some of the cleanest people we've ever had work in our home. We had one small issue with a unit after install and they were out quickly, identified the problem, and resolved it. We are very happy with their work and would recommend them to anyone looking for heating & cooling companies.

Furnace inducer motor failed this morning. Could not find the part local and it would have been 2 days before I could get one. Called around trying to find someone to fix it today and was recommended to them by another company. Office lady was very nice and helpful getting me scheduled today yet. The tech arrived before noon and promptly fixed the issue. Down to earth tech, gave me straight answers to other questions relating the system. Great experience all around and the furnace is quiet and back to normal operation.
