About Us

Serving the valley since 1976

When Jim Donley started our business in 1976, he laid the groundwork for the caring, honest, customer-service oriented organization we are today. Over the years, Donley has evolved by adding more services in the world of air conditioning, plumbing, sewer repair, solar hot water and more. We’ve expanded our employees’ knowledge and skillsets through continuous training, and remained committed to supporting the local community through charitable involvement. At every step of the way, we’ve maintained our excellent reputation for providing award-winning service in the form of repairs, installation, and maintenance for both residential and commercial customers.
