Testimonials
Our air conditioner stopped working during a heatwave, and Left Coast Mechanical came out the same day! They diagnosed and fixed the issue quickly. They were professional and honest throughout the process.

The team replaced our old furnace with a new high-efficiency model, and the difference is amazing. They explained every detail, showed up on time, and left the place spotless. Highly recommended!

We’ve used Left Coast Mechanical twice — once for AC repair and once for a thermostat upgrade. Both times, they provided transparent quotes and exceptional service. These guys really care about doing the job right.
