Your service completed by highly qualified & trained technicians

For the past several years we have attended furnace and heat pump training in both the installation and service of these systems. We have attended factory training for Daikin, Fujitsu, and Mitsubishi Ductless heat pumps along with best practices training through Washington State University for the Heat Pump Installation and Commissioning Certification. This training allows us to offer the best installation possible. The manufacturer can then allow for a 12 year parts warranty and we are able to offer an extended labor warranty.

Our friendly and knowledgeable technicians and office staff are here to make your experience go smoothly 

It’s important to know that the person showing up to install or repair your heating or ac is knowledgeable. Yet, so many repair people seem to be just ‘doing their job’ and not enjoying their job. Here at Marshall’s, we pride ourselves on creating a family like work environment and that not only makes for a better work environment, it helps to keep good people at our company longer. It also ensures the person who worked on your system a few years ago is likely to be the same person you’ll recognize at a glance the next time around.
