About Us

Let our family help your family!

Mountain Valley Heating & Air Conditioning, Inc. is a family owned and operated business.  Proudly serving King County and the surrounding areas since 2003.


Following the loss of our much loved employer, owner Anne Williams opened Mountain Valley Heating and Air Conditioning, Inc. with a vision to replicate all we had been taught -- unwavering commitment to quality work, balancing work and family and trusting God.  Without a doubt, these guiding principles, along with our dedicated employees, and loyal customers are the reason for our continued growth and prosperity. 


Fully licensed, bonded and insured
Contractor’s License: MOUNTVH970N2

Our goal is simple; to take care of your family’s heating and air conditioning needs for a lifetime.

In Loving Memory of 

Richard Lee Gowin
