Frequently Asked Questions About Indoor Air Quality in San Diego, CA
What are the most effective indoor air quality upgrades for a home in San Diego?
The highest-impact IAQ upgrades in order of effectiveness: (1) MERV-13 media air filter — catches particles down to 0.3 microns; (2) whole-home dehumidifier (critical in humid climates) — controls mold-triggering moisture; (3) UV germicidal light on the air handler coil — kills bacteria, viruses, and mold on the coil surface; (4) ERV/HRV ventilation — brings in fresh filtered outdoor air while recovering energy. Portable air purifiers help individual rooms but don't replace whole-home solutions.
How much do whole-home air quality systems cost in San Diego?
Whole-home IAQ system costs in San Diego: MERV-13 media filter upgrade $200–$600 installed; UV germicidal light $300–$800 installed; whole-home dehumidifier $1,200–$2,500 installed; whole-home humidifier $500–$1,500 installed; ERV/HRV ventilation $1,500–$4,000 installed. Most homeowners build an IAQ package combining 2–3 of these systems for $1,500–$4,000 total. Federal energy credits apply to qualifying ventilation equipment.
What MERV rating should my air filter be?
MERV 8 is the standard recommendation for most homes — it captures pollen, dust mites, and mold spores without significantly restricting airflow. MERV 11–13 is recommended for allergy and asthma sufferers — it captures finer particles including some bacteria and smoke particulates. Do not install MERV 14+ filters without confirming your system can handle the increased static pressure; improper high-MERV filters can reduce airflow and damage HVAC equipment.
Do UV lights in HVAC systems actually work?
Yes — UV-C germicidal lights installed on the air handler evaporator coil are effective at killing bacteria, mold, and some viruses on the coil surface, preventing the mold and biofilm buildup that commonly occurs in humid conditions. Studies show coil UV lights can reduce coil contamination by 90%+ and improve airflow by keeping the coil clean. In-duct air purifier models (like RGF Reme Halo) also treat moving air. A licensed HVAC contractor can recommend the right system for your home and San Diego's climate conditions.
