Grand Slam Air Conditioning and Heating

Grand Slam Air Conditioning and Heating has operated from the Simi Valley area since 1993, making it one of the longest-running family-owned HVAC contractors in the San Fernando Valley. The company holds a 5.0-star rating across 38 verified customer reviews, and serves residential and commercial clients in communities including Northridge, Granada Hills, Van Nuys, Encino, and the broader San Fernando Valley. Bilingual staff communicate in both English and Spanish, ensuring clear communication for diverse homeowners throughout the region.

The company differentiates itself through transparent pricing and technical precision. Technicians triple-vacuum-check refrigerant lines during new installations to prevent future leaks, and provide homeowners with documented proof of completed work. The business installs Gree ductless mini-split systems featuring built-in smart home connectivity, and provides financing options for major equipment purchases. All technicians are experienced with both traditional central air and heating systems as well as modern variable-speed ductless configurations.

Customer reviewers consistently highlight technician Rick by name for exceptional service. When Brent Noll needed a mini-split system installed for his apartment, Rick coordinated with the landlord to update two units in the building, responding to calls and texts when other contractors would not. During a heat wave, Rick arrived same day for Daniel Kim's AC emergency and restored cooling quickly. Tommy Nguyen's heat failed entirely, and Rick diagnosed the issue, located the needed part the following day, and completed the repair with fair pricing.
