They say it’s all about who you know. In Los Angeles, you just can’t get by without a solid set of relationships. Likewise, being an HVAC contractor is as much about truly understanding the comfort needs of homeowners as it is about licenses and expertise.

That’s why we at JMS Air Conditioning and Heating make it a point to build long-term relationships with our clients. This mindset has served as our foundation since 1993, taking us from a one-man operation to the 30-man HVAC team that we are today.

You’ll find that we take a personalized approach to all of your Los Angeles HVAC needs. Where other contractors might insist on replacing your entire system—and charging you for it, too—our technicians have the skills and expertise to work with you. We can promise that for you with:

100% Satisfaction Guarantee.

Heating and air conditioning repairs, services, and installations for all makes and models—no matter how old or how big.

A lifetime warranty on repairs for Preferred Customer Club members.

We’ll do whatever it takes to ensure your home is the most comfortable place to live, whether that means working to improve your existing HVAC system or installing a brand new one. Either way, you can anticipate a solution that is tailored to maximize your heating and air conditioning efficiency, comfort, peace of mind, and even save you a little extra money.
