5 Diamond, Inc.

The 5 Diamond Mechanical name derives from the desire to provide the very best customer service while utilizing technologically advanced and time tested products, and materials for all applications and installations. After receiving a degree in HVAC and pursuing various trainings in controls and other applications, our President Carlos Martinez worked in the engineering department at San Diego’s only 5 Diamond Resort, The Grand Del Mar. This is where the principles of 5 Diamond service was inculcated in him and in time he acquired the skill set to provide seamless flawless service that sprung from a heart full of passion. Carlos relished his work duties with HVAC and more importantly he could see firsthand how his workmanship and manner of conveyance had a deep lasting impression on the ones he provided his services to. Carlos meditated on the possibility of having an HVAC company that delivered top of the line seamless polished service for the work trades. At the age of 21 years old, after receiving his contractors license Carlos started 5 Diamond Mechanical. A short time later, Carlos became business partners with Nick Mullins Vice President, Nick started in high school working for his uncle’s HVAC company. This where a strong root system of high quality workmanship and integrity were firmly established. Both these leaders together and their strong suits have created a team and a culture that has made 5 Diamond Mechanical a top performer in San Diego. The 5 Diamond Mechanical team is available and ready to serve you at your convenience.
