My technician Billy was very thorough. He explained everything to me and gave me a detailed future repairs to my furnace. He is very smart, brilliant and knows what he is doing. I am so pleased to have him for my technician.

Absolutely terrible customer service and over priced, expensive. They were a constant to our family for many years for heating, air conditioning, plumbing and electrical work. They have now left my daughter in the cold during the holiday season with tagging a furnace that shouldn’t have been tagged. Now she scrambles to find someone who can service her needs. I guess the buyout in April by Redwood has completely wrecked a locally based company. Absolutely sickening!!

I signed up for the Cardinal care club. Super easy process with many benefits that make it worth your money. Customer service was excellent. Already had my first service with a furnace check by Alejandro. He was extremely courteous and took his time explaining everything he was going to do and afterwards everything he had done. He gave his service recommendations in a way that I didn't feel pressured into anything. He was excellent. I highly recommend using this company ⭐️⭐️⭐️⭐️⭐️

My furnace went out on Thursday, I called Cardinal Heating and they sent Nathan out to diagnose and fix it. It needed a new compressor which had to be ordered. Friday i got a call that they could come fix it. The manager himself brought the new compressor to my house ahead of Nathan coming to install it. I'm very grateful for how fast they were able to get the heat turned back on. I'm a senior aged woman who tends be feel cold most of the time. I would recommend Cardinal in a heartbeat!!!
