Cardinal Heating & Air – Professional HVAC Service in Issaquah, WA

If you want an HVAC company that stands by its work, then you’ll want to go with Cardinal. They did a big job for us, and as with any big job, there were bumps in the road. Thanks to the team at Cardinal (most especially Dave and Tom), we were able to get back on track quickly. Also a big thank you to installers Drew and Luis. They were professional and efficient, and I have confidence in their work. Going above and beyond, Drew and Luis also did a very thorough quality control check after the installation. I appreciate that Cardinal has been open, honest, and responsive every step of the way. I would choose Cardinal again without hesitation and I would recommend them to my friends and family. It’s a company that has earned my trust.

Cardinal Heating replaced my 30+ year old furnace and added AC at a great price. Their team was awesome led by Jerrar Hayes and did an excellent job.

Appreciate the workers who have helped to install our new heater. We just had a visit by Jerrar - I appreciated his punctuality and good communication and sense of humor. Thank you!

Jerrar was amazing to work with! He went above and beyond to fix my furnace, working diligently to ensure everything was running smoothly before leaving. He took the time to explain the issues clearly, helping me understand what went wrong and what steps were needed to resolve it. His professionalism, attention to detail, and willingness to answer all my questions made the entire experience stress-free.

Always great service by Cardinal. Jarred was very courteous and friendly.

We have a 100+ year old Craftsman house and wanted to upgrade to a heat pump system. We had multiple bids which were unsettlingly all very different. Jonas from Cardinal was the most thorough and ended up recommending a hybrid system very different from the others. (Before I mention the quality of the work, I say want to say the system works extraordinarily well - the decision the accept the limitation of the 100 year old ducting system and work with it was brilliant.) We had the new heat pump system installed in July 2024 with a new ducted system for the second floor. The Cardinal installation team really did an excellent job. They were also very professional, and thoughtfully walked us through some of the installation issues and decisions we needed to make . Their daily cleanup was excellent. We are continually surprised by how well the systems works. We mostly wanted to use the system for the summers, particularly for the smoke events and weren't sure the cooling would be well distributed. But thanks to the suggestion by Josh that we wire up a switch to use the old gas furnace's fan in the summer, the cool air is distributed pretty well. And the heating effect is really wonderful. We had a post installation problem with leaking condensation causing some ceiling damage. Cardinal made good on the installation paying for the repairs continuing their excellent service. Cardinal is one of the best contractors we ever worked with - I can't recommend them highly enough!
