"I am thankful for everything my Cardinals team do. Having the warranty and membership with Cardinals is a great peace of mind. This time, Jill stayed and investigated the issue with the heatpump. I am thankful the problem was resolved. Like every time a tech comes, I learned something new about best way to operate the central air system. Thank you Jill Heiser."

"I spoke with the owner at 2:30 in the afternoon and he was here for an estimate at 5pm. We booked an appointment for a new furnace that day. We had problems with the old furnace and the owner worked on it, attempting to replicate the problem. A Tech was sent out the next morning (free of charge) to get us through until the new furnace was installed 6 days later. Everyone we dealt with was VERY knowledgeable, explained each step to us, were expedient and very thorough. Pricing was excellent. This company will be the only company we call for ANY HVAC work. HIGHLY RECOMMEND!!!"

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."
