Dennis Davis, Vice President
Dennis Davis is the 2nd generation owner of College Place Heating and Air Conditioning which was founded 71 years ago.
He is paving the way for the 3rd generation to continue to serve the Walla Walla Valley HVAC needs.
A significant part of best serving any customer market base is good government regulatory policy.
Dennis has observed over the years that under regulation has encouraged negative outcomes for his market and that proposed over regulation is even more negative for home and business owners.
Over regulation and limiting HVAC solutions increases the cost to consumers and increases the underground economy which is a ‘healthy’ competition.
Dennis believes that belonging to and supporting WA HAVC is the best investment in fine tuning government involvement.
Healthy contractors along with appropriate government policy makes for the happiest consumers and a thriving state economy.
