Skilled evaluation of your home including a heat loss calculation, mechanical and electrical permits and inspections. All systems are installed to current building codes. All systems installed to the “best practices” Standards of PSE and the manufacturer's specifications. Marshall’s is a tier 1 level Puget Sound Energy service provider for all types of heating systems. As a result, we are able to complete and submit all utility rebate applications and give instant utility rebates upfront to our customers. First year service and maintenance inspection.

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.

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.
