Clean air in Costa Mesa 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.
Costa Mesa is home to roughly 112,822 residents across CA. We serve East Side, Mesa Verde, and South Coast Metro, 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.
“Called three companies for indoor air quality; this one actually answered on a Saturday in Costa Mesa. Arrived with the right tools, finished the job, cleaned up.”
“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.”
“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.
As a rule of thumb, if repair costs exceed 50% of a new unit's price, or your system is over 10 years old and needs a major repair, replacement is usually the better investment. {company}'s technicians will give you an honest assessment.
14.3 SEER2 (the 2023 federal minimum) saves vs. a 10+ year old unit. Going to 17 SEER2 pays back in 6-8 years on Costa Mesa's cooling hours. Above 20 SEER2 only pays back if you stay in the home 12+ years.
Set your thermostat to 68°F in winter and 78°F in summer when home. A programmable or smart thermostat can automatically adjust temperatures when you're away or sleeping, saving 10–15% on energy costs. {company} installs and configures smart thermostats.
