About Big Air Heating & Air Conditioning
Big Air Heating & Air Conditioning serves Concord and the surrounding California communities with a 4.8-star average from 320 reviews. The contractor handles residential heating and cooling systems, offering tune-ups, repairs, and replacements. Their service team operates Monday through Friday from 8 AM to 4:30 PM, responding to calls throughout the East Bay area.
The company differentiates itself through specialized water heater expertise that extends beyond typical HVAC work. Technicians handle tankless water heater service, anode rod replacements, and expansion tank installations, services that many HVAC contractors outsource. This in-house capability allows customers to address water heating needs through a single trusted provider rather than coordinating multiple specialists.
Customer reviews consistently highlight technicians Isaiah and Victor Mezquita by name for their communication and technical skill. One reviewer described Isaiah arriving on time, performing a thorough system inspection, and clearly explaining all findings and options. Another detailed Victor's work on a tankless water heater, noting his detailed explanation of issues discovered and the necessary repairs. A third reviewer mentioned scheduling Isaiah for same-day service during summer heat, praising the preventative maintenance that prepared their systems for extreme temperatures.
