Bourque Mechanical is family owned & operated since 1986!Our main gaol is to be honest with the customer..Give us a call for an estimate,for service or for a question and we will be happy to help you out! Award winning.

"We recently had Bourque Mechanical Systems replace our old oil boiler, and the experience was outstanding from start to finish. Steve was our main point of contact, and he was excellent throughout the process. He was straightforward, never overpromised, and consistently steered us in the right direction, which made a potentially stressful project feel very manageable. The quality of the work was legitimately the best we’ve experienced from any organization that has worked on our home in the last ten years. The job itself was sizable, yet the team was thorough, professional, and completed everything in a single day without cutting corners. What really stood out to me was the attention to detail. The work site was kept clean, and the final product was incredibly well done. I truly appreciate a clean, organized job site, and Bourque exceeded expectations in that regard. I couldn’t be more impressed and would absolutely recommend them to anyone needing mechanical or heating system work."
