Boiler Replacement in Bellingham, WA 98225

July 2, 2026

“Tyler and Kevin did a great job installing our Navien combo-boiler this week. The quality of the installation is evident, and they were extremely professional and respectful of our condo while they worked. Tyler was patient with my questions and gave me a thorough explanation of the system components once it was completed. We are very pleased with the new tankless heater and associated components. We are very happy that we selected West Mechanical for this replacement, and we look forward to the outstanding service we have received from Juan in the past. – John & Peggy Kirchgessner”

“Brett, along with Matt, devised an astonishing project with our group of local realtors to let us know about service options we could offer our clients. Both when selling a home and prepping HVAC systems or if in the midst of inspection callouts. Inspections, service, responsiveness, quality and pricing mentioned along with even appropriate "closing gifts" for clients that would help their HVAC health in their homes in the future. I would recommend other realtors to create an opportunity to meet with Brett and discuss how to enhance their service network for serving our clients with excellence.”
