Air Temperature Specialists

Air Temperature Specialists is a licensed HVAC and plumbing contractor operating from offices in Temecula and El Cajon, California. Holding California contractor license CL #763576, the company has served San Diego and Riverside counties since 2017, earning a 4.9-star average across 264 customer reviews with around-the-clock availability every day of the week. The locally owned business handles both residential homes and commercial properties including multifamily buildings, offering integrated service across air conditioning, heating, hot water systems, and plumbing.

What distinguishes Air Temperature Specialists is their commitment to same-day service with fully stocked service trucks, meaning technicians arrive prepared to complete most repairs in a single visit rather than ordering parts and returning later. They offer maintenance contracts for ongoing AC and heating care, new system installations including rooftop commercial units, and handle complex jobs ranging from slab leak detection to sewer line clearing. Their team includes technicians Anthony and Charlie, whom multiple reviewers specifically credit with identifying underlying installation issues that had persisted for years and resolving problems other contractors could not fix.

Reviewers repeatedly name technician Anthony for arriving on time, clearly explaining the work before starting, and solving multiple problems during a single service call. One customer described Anthony as the reason they will remain a long-term client after he restored heat during a cold spell, while another noted he identified and fixedinstallation errors from twenty years prior that had caused ongoing frustration. Technician Charlie received specific praise for professionally handling a full air conditioning replacement, explaining each step of the demolition and installation process while managing a nervous dog in the home.
