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.
From your first call through system startup, we manage the entire process. Our crew handles the technical work while you stay informed every step.
Contact us at 213-369-3859 to discuss your HVAC needs, whether residential or multi-family. We listen to your situation and answer initial questions.
Our technician visits your property to inspect your current system and identify what needs repair, replacement, or installation. We explain findings and provide a clear estimate.
We install new systems, replace units, or service existing equipment. We handle all mechanical work and pull required permits on your behalf.
Once work is finished, we walk you through your new or serviced system. We're available for questions and follow-up service as needed.
We pull all required permits and coordinate inspections. Your approval comes before we start, and we clean up when we're done.
