We had a tech come out as a scheduled service visit. Shortly after taking a look at everything he tells us that our heat exchanger is cracked and could be harmful due to the threat of the potential of it leaking carbon monoxide. He then tells us that he can't legally leave our furnace on which we could understand. He offers to send out his sales guy to give us options for a new furnace. The salesman arrives within the hour with some replacement options ranging in price from $6500 to almost $8000. We then decide to get another quote from a referral whom we contacted shortly after being given the

We have come to rely on Cardinal as our first choice, go to company, for all our plumbing, electrical and HVAC needs. After several years of trying various companies, including Cardinal, they have come out on top of almost every category including but not limited to professionalism, accuracy of diagnosis, quality parts, and repairing correctly the first time. We really appreciate that the techs are trained, certified and professional in their appearance and COVID safe (masks, shoe covers). I am confident you won't find a better value.

We appreciate the customer service. The office is very responsive and the field technicians are very friendly. We have an older home and needed to have several faucets, toilets and plumbing issues taken care of this year. Matt has always answered our questions and is very personable.

Matt was amazing! He was very helpful and explained everything clearly. He even found an issue with the toilet we were unaware of and fixed it. I will definitely use Cardinal again.

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.
