A very positive experience with Cardinal. Paul was on time, professional and answered all of my questions. I had an electrical outlet installed for a sump pump and was scheduled for a wiring repair, but this ended up being more complicated than anticipated. Paul worked exceptionally hard to resolve the problem, but ultimately, it will require additional work. He kept me informed throughout and provided suggestions to resolve the issue. I look forward to working with Cardinal in the future.

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.

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!

We've been using Cardinal for several years now for heating and air. We have the Cardinal Cares plan, so we get a call every 6 months to schedule our heat and AC maintenance. We also used Cardinal recently to clean out dryer vents. The technicians are always professional and friendly. I love that we get a text with our technicians name and picture when they're on their way so we can be sure that the person at the door is who they say they are.

He was responsive, walked me thorough things over the phone and in person, and did an incredible job installing completely new piping for our shower/tub. Very professional and did excellent work. Would recommend to anyone in need of plumbing service.

We have never had a bad experience with Cardinal! When our water heater finally gave up the ghost after being given a year to live seven years ago, Cardinal was our first choice. By the end of the day on the same day I took my first unexpectedly cold shower, we had called and had service scheduled for the following morning. The plumber that installed our new water heater was professional, friendly, took extra time to explain things and answer questions, and did the install work quickly and cleanly. They removed the old and busted water heater and replaced it with new hotness! The work was completed in just four hours from the moment the technician stepped through the door to when we signed off on work completion! The cost was good, the service was fast and efficient, and we'll be glad to work with them again on future repairs and replacements. Just, hopefully not too soon. 🙂

When I worked in the trades 20+ years ago, Cardinal was what our company used for all HVAC needs. What stood out was the professionalism of the technicians.

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!

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.
