From basic to cutting edge technology, Mayo Mechanical has been designing and building thermal comfort systems throughout Southern California since 1985.

Innovative comfort systems created without compromise

Our history

Originally established as David Mayo Heating & Air Conditioning in 1985, Dave opened for business with just $850 in the bank after graduating with an AS degree from Cypress College in Air Conditioning/Refrigeration.
As with many in the construction/service industry, Dave comes from humble beginnings. He started out as a tailgate jockey equipped with only his family, a truck, a home phone and an answering machine. He quickly outgrew the truck and worked out of his home garage, until that, too, was outgrown. In 1999 Dave got out of the house and leased a 2,000 square foot office in Laguna Canyon with the space he needed to design and build mechanical systems at even larger scale.
Next in 2006, Dave Mayo Heating & Air Conditioning became a California Corporation called Mayo Mechanical. New name, same family, committed to quality work and establishing strong customer relationships. These strong relationships make up much of our business – the majority of our clients come from referrals.

Our focus

What we do is design and build systems that make people comfortable. Systems that take into account the architectural features of buildings – high performance systems that blend with the soul of the living space. Systems that are effective, economical, long lasting, and meet or exceed even the most rigorous energy compliance regulations. 

From the beginning, Mayo Mechanical, Inc. has been an industry leading innovative design/build contracting firm, known for its expertise in radiant floor heating and hydronically driven mechanical heating/cooling/water heating systems.
