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

Our electric furnace wouldn't go on. Called Marshall's Heating and talked to Greg about having a technician come out and troubleshoot the problem. He called me back within 2 hrs and said he would have a tech available later the same morning and would call before he came out.
Got the call and the technician, Ben, arrived when he said he would. Checked things out and found a problem with my old thermostat and problem solved. Relatively a quick fix and a fair charge for the service call. Would recommend Marshall's for your heating needs!

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 called Greg on the recommendation of a friend after I had gotten a bid from Barons. He came to the house, inspected our system and gave me a couple of recommendations for a heat pump system. I was surprised that is quote was $5000 cheaper than Barons. Yes- $5k. I was able to read up on the equipment he recommended compared to Baron and realized Baron's sales rep was adding things on that I didn't need. I gave Greg 50% down and we set a date. The Install crew were a lot of fun and had it done in a day. Thay were on time and very professional. I would recommend them to anyone

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

Marshalls put in my system over 10 years ago when it died in the midst of a very cold spell. They were very responsive and designed a new system that has worked much better than the old one. Since then they have maintained the system annually and always quick to come out on a question or related issue even if I view it as non-urgent. Great people to work with!!
