About Marathon Plumbing, Heating and Air

Marathon Plumbing, Heating and Air has kept Southern California homes comfortable since 1990, building over three decades of trusted service across Los Angeles, Riverside, and Orange Counties. The company holds a 4.9-star rating from 507 reviews, reflecting consistent professionalism in every job. With locations in Colton, Canoga Park, Whittier, Covina, Anaheim, and Signal Hill, their technicians respond quickly to neighborhoods spanning from the San Fernando Valley to inland Riverside.

What distinguishes Marathon is their commitment to modern home comfort technology. They offer financing through Service Finance, including 12-month zero-interest payment plans and same-as-cash options that make system replacements accessible. Their website advertises free diagnostics with repairs over $500 and a $89 drain cleaning special with free camera inspection. The company installs equipment from major manufacturers and provides indoor air quality solutions alongside traditional heating and cooling services.

Customer reviews spotlight specific technicians who deliver exceptional service. Dale resolved a complex leak issue for reviewer David Nelson, tracing water damage to a forgotten drain pipe other contractors had missed. Bud arrived at Jim Wells' home within 45 minutes of the initial call, then returned the next morning with equipment to precisely locate a hidden leak. David earned praise from Jeni Clark for on-time arrival, thorough explanations of their membership program, and efficient repairs. Danny impressed Stella with his knowledge, meticulous work, fair pricing, and warranty explanation.
