How does Casa de Oro's climate affect this service?
Casa de Oro hillside neighborhoods along the SR-94 corridor run on 1970s-80s tract HVAC systems hitting end-of-life, heat pump conversion is the dominant upgrade path, with the East County summer heat (95-105°F) justifying premium variable-speed equipment that handles the extended cooling season efficiently.. East County homes benefit most from whole-home air cleaners during fire season and Santa Ana dust events.
What MERV rating should I use?
MERV 11 is the minimum that actually catches meaningful fine particulate. MERV 13 is the sweet spot for allergens, pet dander, and wildfire smoke. MERV 16 filters in a proper 4-inch cabinet are excellent, but a 1-inch MERV 16 in a standard slot usually chokes airflow. Always pair high-MERV with adequate filter area.
Do UV lights really work?
For coil mold and airborne pathogens in the air handler, yes — UV-C directly on the coil is proven. For whole-home sterilization of breathable air, the evidence is weaker. We recommend UV-C on the coil, not as a standalone air purifier.
