Yes, a dirty evaporator coil is a common issue here, often caused by our local dust and pollen. A clogged coil can't absorb heat effectively, reducing cooling power and making your system work harder. During a repair visit, we thoroughly clean the coil, check for proper refrigerant charge, and ensure the entire system is sealed and functioning correctly. Addressing this promptly can restore cooling performance and prevent higher energy bills.

We start with a detailed consultation to understand your home's unique layout, insulation, and your family's comfort needs. For San Francisco's varied microclimates, we help select a correctly sized and efficient system to avoid overworking equipment. Our installation process prioritizes precision and cleanliness, ensuring the new system integrates seamlessly with your existing ductwork and operates quietly and reliably, providing balanced comfort throughout your home.
