Heating & Air Conditioning / HVAC near Eureka

“Klaus has been amazing to work with. I trust them to give me honest advice even if it leads to me not needing a plumber. I have used them to replace my hot water heater, install a water softener and work on my faucet. I haven't found a better plumber service. And Kristi, the scheduler is great at getting someone out ASAP when I have an issue.“

“Heinold Heating & Air Conditioning installed our zoned Geo Thermal system in our home while it was being built. Heinold also installed two mini splits later on at different times as well as a garage floor radiant heat system that uses an electric boiler and a Reznor hanging propane heater. Heinold is always professional, courteous, and neat whether doing a new installation or doing a service call.“

“Our AC was not keeping up and it was gradually getting warmer in our home, on a 100 degree day. I called Hinrichsens and a worker was out to look at it yet that afternoon. He had us up and running quickly. He was curtious and efficient. We were so very grateful for the quick service!!“

“Furnace stopped working in very cold weather. They arrived quickly and fixed the problem. Professional service to be sure!“

“We've had them do work on our A/C a couple of times since moving into the area in July 2021. They also came out and replaced our water heater in September. Great team of people. We like them so much we signed up for their yearly maintenance plan and are planning on having them install new HVAC soon.

UPDATE 8/21/2025: Still love working with this company. Working with Dale is a breeze. He’s friendly, knowledgeable, and efficient. Had our A/C maintenance done today and at the last minute decided to upgrade our thermostat. Dale had the part and installed it quickly.“
