JMS Air Conditioning and Heating

JMS Air Conditioning and Heating has served the Los Angeles area since 1993. This Van Nuys-based contractor holds a California state contractor license and maintains a 4.8-star average from 389 reviews, making it one of the most reviewed HVAC shops in the San Fernando Valley. Their crews cover Van Nuys, Encino, North Hollywood, Reseda, and surrounding ZIP codes, handling residential and light commercial work across every major equipment category.

What separates this shop is a structured maintenance membership called the JMS Preferred Customer Club. Members receive 20% off repairs, a lifetime repair warranty, 5% off new equipment, and zero overtime charges. The company also markets itself on eco-friendly solutions and a 100% satisfaction guarantee, promising personalized assessments rather than one-size-fits-all quotes. Their service menu explicitly includes ductless mini-split systems and heat pumps alongside conventional central air and forced-air heating.

Reviewers repeatedly name individual technicians and link them to specific outcomes. Yola describes how Jeff visited her home and diagnosed a rusting heater, then patched it temporarily so she would not lose heat while awaiting replacement. Damian impressed Leda by calling ahead before arrival, completing a thermostat swap promptly, and leaving the space clean. Mark credits Eduardo with identifying an airflow issue linked to his package units on the roof, noting that every interaction from the owner downward felt thorough.
