About Left Coast Air — Your Local Riverside County HVAC Team
Left Coast Air is a family-owned heating and air conditioning company built on a simple idea: do honest, high-quality work for our neighbors and stand behind it. A decade in, that's still exactly how we run.
Our Story
We founded Left Coast Air in 2016 and have spent ten years earning trust one job at a time across Menifee, Murrieta, Temecula and the wider Riverside County area. We're based in Menifee, so this isn't a territory we service from far away — it's home.
Because we're an independent, multi-brand contractor, we're not locked into pushing any single manufacturer. That means when we recommend a repair or a new system, it's based on what's right for your home and budget — not a quota. We install and service all major brands, including York, Carrier, Daikin, Lennox, Maytag and AZ-Pro.
What We Do
We handle the full range of residential and commercial HVAC work — ducted and ductless. That includes AC repair and installation, furnace repair and installation, ductless mini-split systems, seasonal maintenance, and commercial HVAC for local businesses.
Meet Paul St. Amant
Paul St. Amant is co-owner of Left Coast Air and stays hands-on with the business every day. His name is on the license, the work, and every promise we make to a customer — and he'd rather earn a repeat customer than win a one-time sale.
