In a commercial building, I have a 60-year-old Hayes natural gas furnace that a previous contractor inexplicably disconnected from the new thermostats they installed (they wouldn't come back to fix the error, because they were afraid of the Hayes furnace!). Also, decades of different HVAC control units were still installed but disconnected, and I inherited a spaghetti of wires that I had no idea about. Evergreen State Heat & AC came in and did an audit, removed all the superfluous devices, got the Hayes furnace under thermostat control, and life has been great ever since. Of course, I hired them for routine periodic maintenance. Smart and willing to take on challenges, I heartily recommend them for commercial buildings of any age.

We've used Evergreen State Heat & AC for a few years now for our regular furnace maintenance. They are always able to schedule us promptly and their service technicians are responsible, friendly, quick and thorough. They have been good at answering my questions about how to maximize the life of our furnace or concerns I've had about filter quality and efficiency. Jackson came out today and went the extra mile to retrieve an air filter lost to the stack. I appreciate their professionalism and community spirit.

Professional and friendly as always. I've used Evergreen State Heat & AC for years for annual service plus occasional repairs on my very old furnace. Always happy with the service and results, thank you!!

Evergreen is hands down the best company to do business with. Professional, knowledgeable, and friendly beginning to end. Fairly priced, too. I use them to maintain my 20 year old furnace and I will be using them for all my electrical needs in the future.5 stars all the way.
