Other Maintenance in Birch Bay, WA 98230

March 13, 2026

“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.”

Water Heater Repair in Coupeville, WA 98239

August 24, 2025

“The other day we had an issue with our hot water heater. Upon Aaron's arrival he immediately explained what needed to be done. The heater needed a new thermostat which had been ordered. Aaron worked on it till it was completed even though he had issues with the part. After a period of time he had completed the job though it was some what difficult.
I really appreciated the time he spent and he would not leave until it was installed correctly. Thanks West Mechanical and of course Aaron. .”
