EXCELLENT Based on 567 reviews Posted on Google Mathew WatsonTrustindex verifies that the original source of the review is Google. Cardinal debugged my furnace as needing a new controller board, I agreed to continue, and a new board installed. The new board didn't work, and further debugging found an electrical problem: ground and neutral should be at the same voltage (0 V), but they were different by about 20 V. After hiring an electrician to repair the electrical system, the new board worked. I'm unhappy. If controller boards fail to work because ground and neutral are not identical, then that could, and should, have been checked *before* a new controller board was installed. I feel like the board replacement was premature, and I might have saved about $1000 on the furnace repair ($2000) if a simple check had been done early. Edit: per the owner's recommendation, I called and spoke with the person who did the work. The details are too long to write here. I no longer think it's likely the old controller would have worked, but I still wish the electrical problem had been diagnosed earlier. Then we could have discussed my hiring an electrician to fix the power vs. swapping out the control board at that time. I'm upping my review to 4 stars.Posted on Google Judith ShahnTrustindex verifies that the original source of the review is Google. We;ve worked with Cardinal Heating & Air for years - first with our furnace and now with mini-split units throughout the house. Each technician is professional and friendly and they always help us troubleshoot issues if there are anyPosted on Google J RussellTrustindex verifies that the original source of the review is Google. Had a water heater failure and Eric D and Mike L came to assess the issue, which was diagnosed as a high water pressure issue from the main. Eric put together solutions with two options so I could decide how to move forward. They were on time and very personable and professional. They worked efficiently while keeping me informed during the work. Very pleased with the work that was accomplished.Posted on Google Jana KoeberleTrustindex verifies that the original source of the review is Google. The walkthrough of my home to assess additional AC needs was very informative and helpful. The tech took a lot time to explain my options and try to help me determine the best and most cost efficient route. I was very impressed.Posted on Google Tom BykonenTrustindex verifies that the original source of the review is Google. Thomas did not know what he was doing. He just wanted to replace a 4 year old system. Very dissapointing. Now Cardinal will not return my calls.Posted on Google Ev HaysTrustindex verifies that the original source of the review is Google. Thomas did a great job on my maintenance visit…very professional and a good communicator for all of my questions
