A & B Air Conditioning & Heating

A & B Air Conditioning & Heating has earned a 4.9-star rating from 46 verified customer reviews, solidifying its reputation as one of the most trusted HVAC providers in El Cajon. The company operates Monday through Friday from 7 AM to 4 PM, serving homeowners throughout the eastern portion of San Diego County. Their team includes experienced technicians such as Dustin, David, and Marty, who collectively bring decades of hands-on experience to every service call.

Unlike many contractors who prioritize upsells, A & B Air Conditioning & Heating builds lasting relationships by recommending only necessary repairs. One homeowner told the story of being told by another company that her air conditioner was beyond saving, only to have A & B confirm it could be repaired, saving her thousands toward a full system replacement. The team completes residential installations efficiently, often finishing multi-unit projects in a single day while maintaining clear communication throughout the process.

Customers repeatedly mention specific team members in their feedback. Dustin and David replaced a rooftop unit for Valerie Woodfill, completing the work swiftly at a competitive cost. Casey S, managing an Airbnb located more than 3,000 miles away, coordinated her repair entirely by phone, she praised technician Marty for his knowledge and Jackie in the office for exceptional responsiveness. Mister A has relied on Dustin for both his personal residence and rental properties, citing outstanding communication, first-rate workmanship, and budget-friendly pricing.
