1. Thunder HVAC

Castro Valley, CA3 years in business2 employees

Based in Castro Valley, CA, Thunder HVAC works as a central air installer. The business has been operating for 3 years with a team of 2. An installation visit often starts with removing the old condenser and coil, recovering refrigerant, and preparing the pad. The crew then sets new equipment, brazes line connections, confirms the thermostat works, and walks the homeowner through filters and basic care. Common requests for central air conditioning installation include new central AC system installs, ductwork modifications for cooling, new refrigerant line sets, condensate drain and pump installation and condenser pad setting. Thunder HVAC is also listed for furniture assembly, furniture delivery, handyman and junk removal. Homes in Castro Valley without central air, or with window units in every room, often add a ducted system when there is existing ductwork from a furnace. Include preferences on efficiency level, heat pump versus AC only, and any electrical panel photos, since new equipment may need a dedicated circuit. Electrical upgrades, permits, crane or attic access for the air handler, and removal of old equipment can add to an installation quote. Customers in Castro Valley and nearby areas such as Oakland, San Leandro and San Lorenzo can request a quote. Posted hours are Monday to Sunday. Accepted payment methods include Apple Pay, Cash, Check, Credit card, Google Pay and PayPal. Request a quote from Thunder HVAC on Fixerlane and describe the job you need done.

2. Bair

Castro Valley, CA1 year in business

Bair provides central air conditioning repair in Castro Valley, CA. It has been in business for 1 year. Diagnosis typically starts at the thermostat, moves to the indoor air handler and filter, and finishes at the outdoor condenser. Readings taken at each point help separate a simple fix, like a failed capacitor or clogged drain, from a larger problem such as a refrigerant leak or a compressor fault. Typical jobs for central air conditioning repair in Castro Valley include capacitor replacement, frozen evaporator coil, noisy outdoor unit, AC not cooling diagnosis and contactor replacement. Bair is also listed for duct and vent cleaning, handyman and house cleaning. Rattling, grinding, or repeated clicking noises from the condenser, along with a sudden jump in summer power bills, often lead homeowners to call for a repair visit. Mention where the indoor unit sits, whether in an attic, closet, garage, or basement, along with access limits like a pull-down ladder or locked side gate. System age, part availability for the specific model, and whether the visit falls on evenings or weekends are the usual factors behind a repair quote. Customers in Castro Valley and nearby areas such as Oakland, San Leandro and San Lorenzo can request a quote. Accepted payment methods include Cash, Check, Venmo and Zelle.
