HVAC contractor serving Northridge, CA since 2004

Air Conditioning & Heating Mechanical Masters Inc. has been doing this work since 2004. That is over two decades of installing, servicing, and replacing HVAC systems across Los Angeles and the surrounding region. We are not a startup finding our footing. We are a team of 20 experienced technicians who show up ready to work.

We built this company around two core areas: mechanical HVAC for multi-family and commercial properties, and residential air and heating for homeowners. Whether we are outfitting a large apartment complex in North Hollywood or swapping out a mini split in a Studio City bungalow, we bring the same level of care and precision to every job.

Multi-family and commercial HVAC is its own discipline. It requires coordination, proper permitting, and systems that hold up under daily demand. We have spent years working with property owners, building managers, and contractors across West Los Angeles, the San Fernando Valley, Simi Valley, and beyond. We know what these projects take, and we have the crew to handle them.

On the residential side, we install new systems, service existing equipment, and handle full changeouts when a unit has run its course. Mini splits are a big part of what we do for homeowners in areas like Pacific Palisades, Malibu, Santa Monica, and Thousand Oaks. These systems offer flexible comfort without major ductwork, and we can walk you through whether one is the right fit for your home.

One thing that saves our clients real headaches is permit help. Pulling permits the right way keeps your project legal and protects your property value. We help with that process so you are not left figuring it out on your own.

We serve Los Angeles, the San Fernando Valley, Santa Monica, Pacific Palisades, Thousand Oaks, Sierra Madre, North Hollywood, West Hollywood, Malibu, Simi Valley, West Los Angeles, and Studio City. Our contractor license number is 344739. If you want a team with the experience and the people to back it up, give us a call at (213) 369-3859.
