Electrical Installation in Bellingham, WA 98229

April 14, 2025

“We have been fortunate to work with the folks at West. Every person we worked with; from receptionists to scheduling to plumbing or electrical professionals were all first-rate. Their team arrives on-time, knows what needs to be done, completes their work as well or better than expected and makes sure we are satisfied. When you want the best, make it West.”

Heat Pump Repair in Other 98243

November 22, 2024

“Because of an electrical installation error committed by another HVAC company, our heat pump ran continuously, constantly overheating the master bedroom, sometimes by as much as 15 degrees. When the other company was not able to correct the problem after several attempts, we called West Mechanical for another opinion. Thanks to a team approach involving Tiffany, Brent, Aaron, Kyle and Tony, a complicated problem was identified and completely corrected. Their service was prompt and professional. For the first time in months, our system is operating perfectly. We highly recommend West Mechanical.”

Gas Furnace Maintenance in Bellingham, WA 98228

November 8, 2024

“Honestly, not impressed. Technician was definitely not helpful. Invoice to replace a $39.00 part was over $850.00 and extremely vague. Service department could not justify the excessive cost. Taking my business elsewhere.”

- Chris E.
