Los Angeles, CA Air Conditioning, Heating & Indoor Air Quality Services

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.

Air Conditioning

Is your home ready for the next LA summer? Our air conditioning technicians can install and repair your standard central AC setup, but we’re also highly skilled with custom and high-efficiency systems, such as: zoning systems, inverter systems, VRF systems, and VRV systems. We can inspect your home, your needs, and find out which system is best suited for you.

Heating

California isn’t always the land of sunshine and warm weather. We have our share of cold nights, too, and it’s important to have a highly efficient and operational heating system in place. There’s no reason to pay any more than you have to, and we’ll make sure of that with a flawless installation. We’re also here for any of your urgent repair and maintenance needs.

Indoor Air Quality

We love LA, but there’s no hiding the fact that our air quality isn’t the best. Even so, the air quality inside your home is still likely worse than that outside your home. Air quality is just as much a part of the comfort equation as temperature control, but we can fix that for you with air filters and purifiers, humidifiers, and air duct services.

Maintenance Club

Maintenance is a necessary part of caring for your AC, but it doesn’t have to be a chore. Our Preferred Customer Club makes it worth it. Not only will we remind you of your appointments, but we offer 20% off repairs, lifetime warranty on repairs, 5% off new equipment, 10% on indoor air quality remains, and no overtime charges.
