Indoor Air Quality in Pasadena: what's different
Indoor Air Quality work in Pasadena follows the local climate. Seasonal swings mean both humid summers and dry winters. Duct leakage, filtration and humidity control all affect comfort and bills.
A common Pasadena pattern: wildfire smoke. Smoke from nearby fires makes high-efficiency filtration and air cleaning important, and smoke-damaged ducts may need cleaning.
The indoor air quality services Pasadena homeowners ask for most are air Filtration & Purifiers. MERV-rated media filters and whole-home air cleaners for dust, smoke and allergies.
The City of Pasadena Planning and Community Development Department issues mechanical permits, and historic districts may have rules about visible outdoor equipment. California requires C-20 licensed HVAC contractors.

Should I clean my ducts after wildfire smoke?+
If smoke entered the home, a duct inspection and cleaning plus a filter change is a good idea.
What MERV rating should my filter be?+
MERV 8 to 13 suits most homes, as long as the system has enough filter area. A high-MERV filter in a small slot can restrict airflow.

Coil-mounted UV lights mainly keep the coil clean. Claims about whole-house virus removal should be treated with caution.
