Sunset Air Conditioning & Heating | Experienced HVAC Services in Cupertino, CA

For most Cupertino homes, we recommend a professional air duct cleaning every 3 to 5 years. Our local climate, while generally mild, can still allow dust, pollen, and allergens to circulate through your HVAC system. If you have pets, family members with allergies, or have recently completed a renovation, more frequent cleaning may be beneficial. Our licensed technicians can assess your specific situation during a service call.

Our comprehensive air duct cleaning service involves a thorough inspection of your HVAC system, followed by the cleaning of the supply and return air ducts, registers, grilles, and other essential components using specialized equipment. We focus on removing dust, debris, and potential contaminants to improve your home's air flow and indoor air quality. As a full-service provider, we can also check related parts like your furnace or AC unit during the visit.

Yes, refrigerant leaks and dirty evaporator coils are frequent causes of poor cooling performance in Cupertino. A leak reduces the system's cooling capacity, while a dirty coil inhibits heat transfer. Our technicians are experienced in diagnosing these local issues. We'll perform a detailed inspection, locate any leaks for repair, and clean the coils to restore efficiency. We service major brands like Daikin and Lennox and are available seven days a week to address your comfort needs promptly.
