B & F Auto Air Conditioning

B & F Auto Air Conditioning opened for business in Costa Mesa back in 1974, making it one of the oldest specialty shops in Orange County still under continuous operation. Owner Mike Kosareff runs this family-owned facility alongside technician Gerry, serving drivers in Newport Beach, Huntington Beach, and broader Orange County. The shop displays its certifications prominently on-site so customers walking in know their vehicle is handled by trained professionals. With a solid 4-star average across 25 customer reviews, B & F has cultivated a reputation built on honest assessments and work backed by a guarantee.

Unlike general mechanic shops, B & F devotes its entire operation to climate-control and auto-electrical systems alone. The shop stocks the equipment necessary to service modern R1234YF refrigerant systems found in newer pickups and SUVs, plus vintage automobile systems that require specialized knowledge. Customers traveling from nearby cities specifically seek out the shop for repairs that require more than basic diagnostics, relying on a team that turns away work outside their wheelhouse rather than guessing blindly. A complimentary drop-off and pickup service within 5 miles removes logistical friction for busy owners juggling work schedules.

Reviewers repeatedly name Mike as the reason they returned or recommended the shop. After spending thousands over two years chasing an elusive AC failure elsewhere, Brian Sparks arrived at B & F where Mike diagnosed what no other shop could identify. Roland Martinez brought a Chevrolet Silverado that five other mechanics refused to touch due to lack of R1234YF equipment, praising how Mike explained the fix clearly and delivered better-than-factory performance. When Clarence Y needed a compressor replaced on short notice, Mike and his crew drove him to a nearby appointment then picked him up afterward at no charge.
