First time using Cardinal and they're awesome. Jason came out to evaluate our issues and made constructive recommendations. Sean came to do the vent work for our washer and dryer. Both were very nice and professional. They arrived on time and were very thorough. They explained the work that needed to be done and why. Highly, highly recommend Cardinal for HVAC services

Everyone is very helpful, courteous and friendly. I've used them for the last 18 months which included a complete HVAC system replacement and I'm very happy with them.

I don’t normally write reviews (this is the first), but this was the second time I used Cardinal for plumbing issues, and I am very pleased with the work that was done. Matt K. was the technician both times. He was very professional, friendly, and knows what he is doing. I plan on using Cardinal for future projects, and Matt discussed the options and gave price quotes for each.

We have always been pleased with our service from Cardinal. This time it was a plumbing issue and we worked with Matt. He was very professional and great at explaining what the issue was and was quick to repair. Top notch service once again!

First time contracting a plumber for my 100-year-old house. Called Cardinal off of a strong recommendation from a friend. First phone call to arrival was about 30 minutes! Great professionalism, very detailed and responsive, honest assessment of the issues, and involved me at each step and decision. Despite what looks like it will be a large plumbing project (as I kind of expected) I feel more comfortable knowing I am working with this team.

Rachel W

Our technician Jonathon was professional, knowledgeable, efficient and on time. He resolved all of our plumbing issues and answered all of our questions in a timely and courteous manner. We would recommend Jonathon and Cardinal to our family and friends.

Cardinal does an excellent job with all their services. We have primarily used them for plumbing and electrical over several years and have had no issues.

Katie R

They came out to repair some plumbing issues and did such a nice job I had them come back to install a water softener and a reverse osmosis system. Punctual, great work, everything looks really nice/clean and matches, they were done a little quicker than I expected, and I was billed the same as the quote. Would definitely recommend and use again.

Kevin did a fantastic job with installing the air gap for our dishwasher and replacing our main valve. Everything looks great and he cleaned up afterwards. We also got a chance to chat about a few other plumbing issues around the house that I had questions about. Thanks again!

Jeff B

From the second I called Cardinal to book am appointment to have my water heater looked at until Kevin left after replacing the water heater and installing a water softener, every interaction and discussion was absolutely incredible in terms of their professionalism and customer service. I could not be happier with my experiences and interactions. I am happy to recommend Cardinal and Kevin to anyone needing
plumbing work.

They really saved me last night! At 6p we discovered water in our finished basement. We immediately tried getting rid of the water but We soon discovered that the sump pump had stopped working. I called my local plumber, who I have given tons of work between my commercial buildings and my home, but no response even through the emergency option. I had used Cardinal in the past for an HVAC repair but not for plumbing. I called and to my relief there was a live person who answered after 3 rings. I live over 40 miles away but in a little over an hour the Cardinal service man arrived at my home. He even stayed awhile to make sure that the water was going away. He also fixed another item that I was told that there wasn’t a fix for. I am having them come back to install a more reliable back up system asap. I will continue to use Cardinal for all of my HVAC/plumbing needs.

I called Cardinal plumbing and heating at 7:30 in the morning they arrived at 9:30 in the morning and they installed my new water heater cleaned up and left by 1130. The technicians were extremely polite knowledgeable and friendly. When they left the area was cleaner than when they arrived. I am very pleased!

John C

Amber worked her magic to get a good technician scheduled for an installation service. Levi installed a new and better water softener system in our home. He was very friendly, informative, and did great work. We are excited to have better quality water and we will have significantly reduced costs of softener salt from what we were putting in our old system. Overall great experience! Thanks Levi!

Craig H

T.J. was my electrician, he is so knowledgeable and skilled, he instantly diagnosed what was wrong with my electrical situation thus immediately putting me at ease. A great job !!!!!! I will call upon them for future needs....

Lawrence C

Electrical services: installed new lighting fixtures, inside and outside; installed CO and smoke alarms; grounded gas line to code and removed old fixtures and packing. The two electricians were courteous, kind, wore shoe covers and used drop cloths to protect floors. I'm very pleased with the service.

Pat K

The electrician was very personal and friendly. He wrote booties and a mask and took all precautions for Covid safety. He was sure to answer all questions and showed genuine concern for the customer. We're likely going to be doing a remodel project in the future and we will select this electrician for all future projects.

Brett P

The ceiling light in my bathroom fell from the ceiling and could not be reattached. I called Cardinal, and an
electrician arrived at my home on the same day. He replaced the electrical box in the ceiling which holds the light fixture in place and re-mounted my light fixture. I appreciate the prompt service!

Marc C

Mike Schuett was our electrician. Our Drier outlet and plug to the drier was burnt. I had called Carinal and Jenn was extremely professional. What I enjoyed was Mike took the time to explain things to me, and showed me what had happened not only to the plug of the drier, but also the outlet in the wall! it was so hot that it melted the casing that held the wires in the wall. Mike said, the plastic is strong enough to withstand a lot of heat and for it to be melted, boy were we lucky, he said this could have gone a bad direction (fire). He replaced everything and we are now up and running again.

Thank you Cardinal! and thank you Mike for everything.

Mary K

Excellent work. Technician was wonderful! Highly recommend this company. They came in a timely fashion. Most other electric companies couldn’t make it until November. I needed an immediate response and Cardinal delivered and then some. The technician Ben was great! Very nice and easy to talk to. Was willing to go buy parts for me. I will definitely call Cardinal when I need electric repairs. Ben especially needs a high five for his work and professionalism.

I have lived in Sun Prairie for 15 years and have never used Cardinal until today...and I didn't realize what I was missing out on. I made an appointment this morning after our AC unit died on a 90 degree day. They were able to get me in same day. Our service tech, Trey, was the best Tech we've ever had from any company. He was thorough, explained all of our questions easily, and seemed very honest in all of his explanations. I joined the Cardinal Club and very happy I did.

Jamie V

I recently used Cardinal for a complete HVAC overhaul. I cannot say enough great things about this company. From the sales process through the install, every employee I interacted with was phenomenal. They educated me through out the whole process and made sure we were comfortable as things played out. Our system went out during the recent heat wave, they pulled some strings and and got us installed within a week. A week! In today’s world that is incredible. Thank you Cardinal, you have earned my business for future projects for sure.

Phil M

Jonathon was extremely professional and personable. He was positive and fixed the problem immediately. He was clear with what he thought would need to be completed and the estimated price prior to completing the work after his initial diagnosis. He ended up not needing to complete one item on the estimate and removed it from the invoice. I appreciate his honesty and integrity as other companies may have left the charge on.

I also really appreciated the text from Cardinal telling me what technician was coming, a brief bio about him and a photo of him. As women, unfortunately sometimes it’s a little nerve wracking to know you’ll be home alone with a
stranger. So, having all that information really set me at ease. I 100% will be using Cardinal Heating and Cooling for all our future needs.

Erica S

Cardinal is a wonderful company. I had AC and furnace installed and couldn’t be happier with the entire process. From the estimate to scheduling and the technicians on-site, everybody I encountered was friendly and helpful. Everything was explained clearly and made sure I was satisfied before they left.

Mark P

My furnace/AC went out on Friday and Cardinal had a tech out on Saturday morning. He provided options to either fix or replace the furnace and we ended up having a new unit installed on Tuesday morning. Every employee I talked with was knowledgeable and pleasant and I'll definitely be a repeat customer. Hopefully not too soon though!

Matthew R

What an amazingly positive experience with this company! From the after-hours person who took my call, to the office dispatcher, and finally the technician who came to my home. All were professional and helpful! I called for what was a non-emergency situation but unlike other companies I called they had a tech at my home in 1 hour after my call, not 3 or 6 weeks like the other companies were quoting me. The technician was very helpful and professional. I will definitely call them again for any of my future technical needs!
