About West Coast Air Conditioning

HVAC Services in Ventura County & Beyond

West Coast Air Conditioning was established in 1984 to provide vital air conditioning, heating, ventilation, clean rooms, chillers, computer rooms, and energy management systems for commercial, industrial, and institutional building owners. We are the area’s largest commercial HVAC sales and service company, with over 150 employees and 55 service vehicles serving our customers. Recently, after popular demand from our commercial clients, we expanded our service to include residential properties as well.

Our company is here to provide quality heating and air conditioning systems which are vital to better health, greater comfort, and increased productivity of your occupants, coupled with responsible energy source consumption from the environment in which we live.

When you are ready to bring in the experts, call our Ventura County heating and cooling technicians at (805) 954-9195 or by contacting us online today.
We are always ready to help!

Our Qualifications & Training

We are a NATE “Quality Circle Contractor” which means we have a very high percentage (over 80%) of technicians that are NATE-Certified. NATE, North American Technician Excellence, is the foremost non-profit certification program for technicians in the HVAC field. Though we are a proud Carrier® Factory Authorized Dealer, our NATE-certified technicians can diagnose and repair most makes and models of air conditioning systems, regardless of who installed them. Need a new AC system installed at home? We can help you with that, too!

Our team understands that having an incredible team comes from incredible people, which is why we invest so much time and effort into thorough training for all of our technicians. We encourage each and every person to continually learn and grow, providing them with the resources they need to gain accreditations such as being NATE or Mitsubishi Factory Dealer certified. This commitment to supporting our employees is something that benefits our customers on every single project!

Additionally, we have over 30 years of qualified HVAC service experience. This is a huge bonus for our customers because it delivers more accurate repairs and installations and we perform our work quicker than others.

Our technicians received training from 15 equipment companies to service their equipment. This means we know your equipment well and can provide you with the expert “get it right the first time” service you demand.

Designing with Real HVAC Results in Mind

West Coast Air Conditioning knows you want to safeguard your property investment. Quality heating and air conditioning systems using the latest technologies can substantially lower energy costs, reduce employee or tenant complaints, and add a tangible asset to attract new tenants. We specialize in working closely with building owners and tenants to select, design, engineer, and install their updated HVAC systems to match their operations.

We are proud to be one of the leaders in our area to offer these enhanced services to our customers.
