Outstanding service and response. Couldn't have been nicer or more professional during a crisis. We lost our furnace during a cold spell and the entire team literally saved us. Can't thank you guys enough. Response, expertise, fair pricing, and professionalism. Entire team was 5 Star. Can't recommend a high enough rating. Thanks, guys

Marshall's Mechanical replaced our furnace and installed air condition at the same time. From the first call for a quote Greg was quick to come by, followed up with a quote promptly, and then discussed several options for what I wanted. Their customer service is superb. Marshall's Mechanical does not work on the typical Island Time you see with other companies in Oak Harbor. They
also communicated the process for ordering parts, scheduling install, and let me know exactly what to expect as far as the timeline for completion. My standards are already pretty high for most things, but Greg and Ben

I had a 40 year old electric furnace that needed to be replaced, so I began researching what it would take to replace it with a heat pump system. I had three companies come out to assess my setup and provide quotes. Marshall's was my third call, and was recommended by a neighbor. Greg was very efficient in assessing my house and quicker than the others to follow up with a quote. I was able to schedule an install date within a few weeks of accepting the proposal. Throughout this time, their admin, Megan, was very communicative and pleasant to deal with in getting all of the requirements together

I had a very poor experience with Marshall's Heating and AC and in particular, with Greg. My experience with Greg started out very positive. He came to my home and inspected our current propane furnace and we talked about air flow and that I should increase the return air flow to quiet the system down and make it easier on our next furnace. He was professional and got back to us in a timely fasion but I wanted to get two other bids. It took me a month to get back to him but I did because of my first impression of him and his great price on the new furnace. His quote was 1400 dollars less

Called twice looking for a quote, each call a week apart. No technician was available when i called, so I left my name and number TWICE for them to call back. no call back. I called twice this morning and no one answered. Don't do business with these clowns.

We used Marshall Mechanical to sell us a new heat pump to be installed by their staff in a rental home that we were renovating. Our plans are to move into that home when it comes time to live in a single level home without stairs. So we wanted a quality product and installation. The entire process (permitting, scheduling the install, actual installation, etc.) went smoothly and efficiently. They offer a brand that is widely used in the world market but with slightly less brand recognition than the brand sold by the other ductless heat pump company on Whidbey Island. We had chosen that brand before
