About Whole House Fan Company
Whole House Fan Company operates as a specialized air conditioning contractor serving San Dimas and the broader Southern California region. Holding a 4.9-star rating accumulated across 275 customer reviews, the company has established itself as a Platinum Quietcool Dealer, a designation reflecting both sales volume and installation expertise. Their service portfolio centers exclusively on whole house ventilation systems, with additional offerings in attic insulation, attic fans, and garage cooling solutions. The business maintains Saturday availability, a practical consideration for homeowners who cannot take time off during the weekday.
What distinguishes this contractor from standard HVAC companies is their singular focus on whole house fan technology rather than conventional central air conditioning. Their website references EPA guidance supporting whole house fans for improved indoor air circulation, positioning these systems as both an energy-saving alternative and a ventilation upgrade. The company claims potential utility bill reductions ranging from 50% to 90% when whole house fans replace or supplement traditional AC operation. This narrow specialization means technicians possess deep expertise in one system category rather than broad capabilities across multiple equipment types.
Customer reviews consistently highlight two team members by name. Gabriel, identified as a technician, receives multiple mentions for punctual arrival, thorough explanations of system operation, and efficient repair execution. One reviewer described how Gabriel drove to a local warehouse to retrieve a correctly sized unit after initial installation attempts proved unsuitable, completing the job in a single visit. Another customer noted that Kelsey, the scheduling coordinator, provided patient guidance on unit selection options, demonstrating responsive communication throughout the service process.
