Clean air in Cerritos isn't about a fancier 1-inch filter — it's about matching MERV rating to your system's static pressure and adding targeted UV or media filtration where it actually helps.
Cerritos is home to roughly 50,555 residents across CA. We serve East Cerritos, Cerritos Town Center, and ABC Unified, plus surrounding neighborhoods for indoor air quality. California Title 24 requires Home Energy Rating System (HERS) testing on qualifying AC installs — we handle the paperwork. Ask about current rebate programs from Southern California Edison (SCE), SoCalGas that can offset qualifying indoor air quality work.
Measure return and supply pressure in inches-water-column. Determines what MERV rating your system can accept without airflow restriction.
5-inch media cabinet, UV-C germicidal lamp, whole-home humidifier or dehumidifier — sized to your system's CFM and measured static.
Before-and-after PM2.5, PM10, VOC, and humidity readings. Filter subscription + annual UV bulb replacement scheduled.
Filter MERV too low, ducts leaking supply-side (pulling attic dust), or a pet-heavy home. We camera the ducts + upgrade filtration.
Biofilm on evaporator coil. UV-C coil lamp + annual coil wash solves it permanently.
MERV 13 media filter + regular filter changes. HEPA bypass for severe cases. Keep humidity 30-50%.
Whole-home ERV ventilates without heat loss. Run 24/7 for the first 30 days after install, then adjust.
Whole-home humidifier ($650-$1,400 installed) targets 35-40% RH.
“Indoor Air Quality tech was experienced — walked us through the diagnostic, showed the actual readings, fixed it on the first trip. That's how it should be done.”
“Called three companies for indoor air quality; this one actually answered on a Saturday in Cerritos. Arrived with the right tools, finished the job, cleaned up.”
“Our indoor air quality quote was in writing before anyone touched the system. The tech showed pressures, temperatures, and the failed component. Honest work.”
MERV 11 is the default for most homes. MERV 13 for allergy/asthma households. MERV 16 only when the system is engineered for the static-pressure hit.
Only when there's visible biological contamination or post-construction debris. For most homes a MERV 13 media cabinet is more effective long-term.
Media filtration: yes, measurable. UV-C on the coil: yes, prevents biofilm. Standalone air-stream UV: depends on dwell time. Ionizers in ducts: no evidence of residential benefit.
If your system is over 10–15 years old, needs frequent repairs, or your energy bills keep rising, replacement may be more cost-effective than continuing to repair. {company} provides free estimates and can help you choose the most efficient system for your Cerritos home.
Average home leaks 20-30% of airflow through duct joints — confirmed by a Duct Blaster test. {company}'s $189 duct-leak diagnostic tells you exactly how much cooled/heated air you're losing to the attic before you invest in a new system.
If the builder provided a 2-year warranty and the contractor honors it — yes. After that, compare. Builder-grade equipment tends to be entry-tier; {company} can diagnose and service any brand, and recommend upgrades when they actually pay back.
