Mike Diamond Plumbing, HVAC & Electrical

Mike Diamond Plumbing, HVAC & Electrical is a licensed contractor headquartered in Costa Mesa that has served Orange County and Los Angeles County homeowners for nearly two decades. The company holds a 4.4-star rating compiled from 102 reviews, offering plumbing, electrical, and HVAC work from a team of certified trade specialists. Fully stocked service trucks allow technicians to complete most repairs on a single visit. An 800-number dedicated emergency line handles urgent calls around the clock, every day of the week. Customers from San Clemente to Signal Hill rely on the company for everything from routine fixture replacements to whole-house rewire projects.

Beyond standard repair work, Mike Diamond distinguishes itself through financing options and three tiered membership plans covering heating, cooling, and plumbing systems. Homeowners can spread project costs over time rather than delaying necessary work. The Heating Protection Plan and Air Conditioning Protection Plan bundle annual tune-ups with priority scheduling, giving members a proactive alternative to reactive repairs. Tankless water heater installation and water filtration system upgrades are highlighted specialty offerings that require in-depth technical knowledge and permit coordination, both of which the company's crews manage directly.

Named technicians recur throughout the review file, shaping how past clients describe their experience. Elmer has maintained a client relationship spanning 18 years, with customers noting he explains repair options clearly, cleans up his workspace, and never rushes through questions. Charmaine Horn credited Hamid with diagnosing and permanently resolving a recurring shower issue that another plumber had patched temporarily. During a water heater installation, Hamid identified a worn union joint that would have failed later, earning praise from Rick Edwards for catching a latent problem before it escalated.
