Team Tri-County Heating

Team Tri-County HeatingOur Motto: Work Clean, Play Dirty

Not only do we work hard, we play hard as well. As motorcycle enthusiasts, time off is usually done on “2 wheels”.  

We spend our spare time with friends and family riding dirt bikes, you could say “dirt biking” is our vice.

We race ISDE Enduro and are currently racing the OMRA points series. 

Team Tri-County sponsors a race team for the China Hat ISDE in Millican Valley, Oregon each April and co-sponsored a race team for the 25hr Starvation Ridge GP on Oct. 31-Nov. 1, 2009 in Goldendale, Washington.

The beginning: 1982....

About Tri-County HVACTri-County HVAC, Inc. started back in 1982 when my father opened the doors. After a number of years, he let the license go and went to work for a local heating company.

I started in the HVAC trade when I was a sophomore in high school and 20 years later opened the Tri-County Heating doors once again.

Learned HVAC from the ground up

I started by cleaning the shop and working summers for a local heating & A/C fabrication shop. I graduated from high school and continued my education at the Associated Builders and Contractors apprentice program.  After graduation, I continued to work hard, year after year, taking a variety of courses in the HVAC field along the way.

Over the years, I learned the importance of customer satisfaction, working hard to diagnose and repair what some shops tend to miss. We are often able to find problems with existing HVAC systems and solve problems in an efficient and economical way.

We create and value the relationship we have with our customers, in fact, 90% of our customers are repeat customers or referrals.  We take pride that we’re not just a contractor, but also an honest, fair and friendly resource others are happy to recommend. Feel free to check our A rating from the BBB.
