Fullstar Heating and Air Conditioning has operated as a family-owned contractor in Los Angeles for over 25 years, earning a 4.9-star rating across 64 verified client reviews. The company holds proper licensing to serve throughout California, maintaining extended service hours from 6 AM to 10 PM daily including weekends. Their service territory spans dozens of Southern California communities, including Santa Clarita, Glendale, Pasadena, Burbank, and Santa Monica, enabling same-day dispatch for homeowners facing temperature emergencies across the greater LA basin.

This contractor distinguishes itself through comprehensive indoor air quality solutions alongside traditional heating and cooling repairs.

Client testimonials reveal specific scenarios demonstrating their service capabilities. During a severe heat wave, technician Nicolai arrived with a replacement compressor part already in inventory, restoring a failed cooling system within hours after the homeowner contacted customer service. Another reviewer described a same-day appointment for an air conditioning unit that stopped blowing air entirely, with the technician arriving punctually and completing diagnostics without unnecessary delays. Christian Jay Dicdican noted the team's careful attention to detail during a dual furnace and air conditioning installation, highlighting precise ductwork connections and proper refrigerant charging.
