I was in a jam. A tree fell on my house and my power line was on the ground. MG&E came and turned my power off and would not turn my power back on until I got an electrician to put my meter box back on the house. I called a few different electricians but it was late. I called Cardinal and someone called me back in 10 minutes. They could not do the job that night but they were here at noon the next day and did the job for me when I couldn’t find anyone in a short time. I am very pleased with my service. Thanks Mike

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!

I have used Cardinal since I bought the house for regular maintenance on my ac and furnace. They have replaced both. (They were over 20 years old.) Their service and attention to detail are superb. Their cost is reasonable. The technicians are all competent and friendly. Javier just serviced my ac. He did a thourough job. He explained everything he was doing and the expected results.

Wow -- we have used Cardinal for HVAC installation and servicing in the past, but not plumbing, and we were so impressed. First, Brandon is a phenomenal plumber -- knowledgeable, helpful, and friendly! We used him twice on separate installations and then requested him again for some follow-up issues, and I will request him every time!Second, I can't say enough about how great the customer service at Cardinal is -- you can always get someone on the phone right away and someone will call you back promptly if needed. I love the reminder calls, and the pre-service text that the service professional is on his/her way, along with a photo and short bio. We even received a thank you card after a recent installation! The emails are informative and often have coupons, and sometimes we can find a relevant coupon on the website.We will definitely use again!

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.

Mike from Cardinal HVAC did a great job installing our whole house humidifier. He was on time and very nice to work with. I watched him do most of the installation and he was very knowledgeable. Cardinal HVAC has a great system and was the first to respond out of 3 different companies. They had a quote to us in half a day and came out the following day to do the install. They installed a Honeywell unit which Mike explained has a very good service record with few problems compared to other brands. I highly recommend Cardinal HVAC!UPDATE 6-23-22 - So I am adding to my review because I have again used Cardinal. Our air conditioner started not working correctly and could not keep us cool anymore. Cardinal sent out a technician the same day I called and he was able to get it cooling again within a couple hours!! Yay!! Thanks again guys and gals a Cardinal!!

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.

Levi was amazing. He came out twice, once to cap a gas line and then the next day to install a new water heater which meant redoing water lines, exhaust piping and then redoing an existing gas line. The job was definitely way more than he bargained for as the house in an 1800’s Victorian and everywhere you turn you run into problem after problem. I can’t thank Levi enough, he’s the best!

We recently purchased a home in Cottage Grove and unfortunately discovered a leak in our water softener due to a faulty unit. We contacted Cardinal Heating and AC about the issue and they were AMAZING! They were a pleasure to speak to on the phone. They came the same day and like promised gave us a courtesy call prior to arrival. Brandon was our technician. He was very knowledgeable, efficient and friendly. Hands down a wonderful experience. They are now our go to provider for any future heating/plumbing issues. Thank you!

Hot water heater pilot light kept going out leaving us with cold showers. They were very professional and kept me well informed. As a single Mom I appreciated a picture of the technician and his profile sent to me as I was at work and my kids would be letting him in. My water heater was 16 years old and he could of suggested a new heater but told me I just needed the flame sensor cleaned which saved me a lot of money. I had only been in my condo 1 1/2 months. Although I know I’ll be needing a new heater soon enough for now this does the trick (hot showers for the kids and I) I’ll definitely give them a call for my other mechanics needs! Hopefully no time soon!
