TESTIMONIALS

What Our Clients Say

Cardinal installed a Viessmann system that serves my radiant heat and provides on demand hot water ~7 years ago and did an fantastic job. I have the annual maintenance contract and have been really pleased with the level of service and the quality of their technicians. But yesterday was a stand out moment. David came and did the maintenance. He let me know next year I'll need to replace a part and told me how to integrate it into my annual service to make it more cost effective. And then I mentioned that we're building a small place on Orcas and looking for an efficient solution to heat and cool the space, as well as supply radiant and hot water in a fairly harsh environment that can have a big temperature range. Even though this won't necessarily benefit him or Cardinal, he texted me today with what looks like the perfect system from Steibel Eltron--and was super gracious about responding to and even doing further research on my follow up questions. So kind!!! Everyone--especially in the trades--is so busy these days. It feels exceptional to have such a great human-to-human moment. Big shout out to David. Thank you!

Appreciate Cardinal heating and air for sending out Jerrar to perform quality assurance on recently installed furnace and air conditioning unit. He found several things he would like to see done better. And although they seem minor to me, they’re important enough that he’s going to have his team come back out. Really appreciate the level of detail here. Would recognize Cardinal heating and air to anybody who is looking for a Great service and experience.
