Clients Reviews

We are extremely happy that we contacted DeMarco Mechanical Services. We needed an urgent repair/rebuild of a section of our gas line, and Adrian scheduled an appointment within the next 48 hours. The quote was very competitive and affordable. The actual repair was scheduled for the next few days. We are very pleased that the work was done diligently and tested carefully by him within the expected timeline. Adrian has been super nice, professional, and accommodating to our requests. We highly recommend DeMarco Mechanical Services to anyone who might need its expertise and assistance.

Demarco Mechanical Services worked efficiently to install the new units. Overall, the team was pleasant to deal with and addressed all our questions and concerns. We look forward to having this company take care of our future heating and cooling needs.

It was a good experience. Adrian is a great, nice person and a professional. They provided fast service, even working off-hours (nights) to troubleshoot, followed by next-day parts and repairs for the furnace. Adrian always answered the phone promptly. The pricing and hours were as I would expect for two visits, tools, parts pickup, experience, van, and physical repairs.
