our reviews

“Punctual, thorough, and courteous.”
V .

“We cannot recommend this company enough. We woke up to a cold house. Called West Mechanical and within an hour they were already scheduling someone to come out! That day! The repair man was courteous and answered all of our questions. They scheduled another appointment right there for further work to be done! Then on the worst snow day, Levy braved the roads and drove his own vehicle in order to get here to finish the work. Excellent, excellent customer service!”

Video – Why Does My Heat Pump Smell Like It’s Burning?

You turn on your heat pump, and you smell something burning. What should you do? Who should you call first, the Bellingham fire department or your HVAC technician? First assess what the smell most likely is, and you may not need to call anyone.

Air Duct Cleaning

Your air ducts circulate a supply of fresh and properly treated air. But since ductwork mostly hides behind walls, ceilings, and floors, many Washington homeowners don’t take the time to monitor its condition.

Video – Check Your Furnace Pilot Light

Your furnace may be blowing cold air because the pilot light has gone out. Call us at 360-734-7599 or request service online to have it properly fixed. This is indicative of a bigger problem that requires professional help.
