“Do not recommend. We were existing customers with Cardinal and used them a few times for fixing our plumbing issues and installing our water heater. The first few times went well. However, when our AC broke down during the summer, we called them 3 times to schedule emergency appointment to fix our AC. Each time they "confirmed" the appointment but in the end no one showed up. The people who took the calls seemed to …”
“I set up an apt to replace my garbage disposal with a 12-4 arrival time. They cancelled the apt on the day of the apt. We rescheduled the apt but they only had a Saturday apt available. I cancelled my plans on Saturday so I would be home for a 12-4 arrival time. They cancelled the apt on the day of the apt....AGAIN. They wanted to reschedule but I declined. Not a reliable company.”
“IMPORTANT - IF USING CARDINAL GET A SECOND OPINION BEFORE PROCEEDING WITH $$ REPAIRS: We signed up for cardinal when we moved into our new home.

With more than reasonable pricing, James was able to begin making the necessary upgrades same day, …”
“Kyle was very professional! He knew the details about the unit he was installing, reviewed the contract terms and explained his work upon completion. He was prompt and even cleaned up after the work was completed. Also , he offered to help me replace the contents from the cabinet under the sink! Much appreciated!!”
