our reviews

“West Mechanical is great! Unfortunately I don’t remember the tech who came out but my furnace was acting up and after I was not able to figure it out and calling around local and every place was backed up West Mechanical came out right away from Bellingham to Burlington and in no time they had figured out it was a dirty sensor and so they did a 5 year cleaning and fixed the problem! The tech was great even after I apologized for the inconvenience of where my furnace is at he had no issues and didn’t mind. Great customer service, very fair price and company!”

“Impressive from initial review/estimate development through install completion! Project analysis/bid proposal (Kris) was without a doubt FAR more in-depth, comprehensive and impressive than the two other bidding organization reps solicited for proposals. Kris' analysis/review of options with their pluses/minuses sold us on West Mechanical. Tony's install work was efficient and completed with successful results that sailed through inspector review and have us enjoying a well functioning heat pump unit. We are considering more work of this type in the future and when we decide to go for it will DEFINITELY call West Mechanical to get the job done.”

“My wife and I would like to thank West Mechanical for the recent installation of a Mitsubishi Hyper Heat heat pump system at our home on Camano Island. The team of Kris, Tony, Rudy, and Jack did an excellent job. They showed up when they said they would. They informed us as to what they were planning to do and asked our input where decisions were needed, before they proceeded with each step of the installation. They were always polite and cleaned up their work debris each day. The West Mechanical installation and customer service has exceeded our expectations. We will use West Mechanical in the future and would recommend the company to anyone considering a new HVAC installation or troubleshooting and repair of an existing system.

Brian & Cindy”
