About JMS Air Conditioning and Heating

After moving to the United States, Yossi Mesica, JMS Air Conditioning and Heating’s founder, found his calling in the home services industry. After gaining confidence in both the electrical and HVAC industries, Yossi decided to obtain his contractor license and start a business of his own. In 1993, JMS Air Conditioning and Heating was created and has since grown into a company of more than 30 people who aim to deliver the best customer service, installations, and repairs in the Greater Los Angeles Area.

Our Mission

Unlike other companies, who would just replace an improperly installed system, we look for ways to improve the system’s design to make your home the best possible place to live. Even if that means extra work on our part, there’s no extra cost to you.

This is just one example of how we show our commitment to our customers. The solutions we design for our customers are uniquely tailored to maximize efficiency, comfort, and peace of mind. Not to mention, your wallet!

A Foundation of Trust

We work hard to provide clear, honest, and open communication with all of our customers. This is what allows us to build long lasting relationships with every homeowner who works with us. We take extra care to ensure that our job sites are clean, our quality is exceptional, and our service is phenomenal.

Our Core Values

We’ve built JMS Air Conditioning and Heating on the foundation of these core values:

• Integrity
• Accountability
• Transparency
• Performance
• Communication
• Positivity
• Respect
• Open-mindedness

We’ve been here since 1993 and we aren’t going anywhere!
