Our Professional Services

Whole-House Air Quality Auditing & Particulate Scanning

Indoor air can hold up to five times more pollutants than outdoor air, triggering allergies and respiratory distress. We perform diagnostic air audits using laser particle counters to measure airborne dust, pollen, and PM2.5 concentrations. Detailed testing pinpoints pollution sources so we can design a targeted filtration strategy.

MERV 16 Medical-Grade Filtration Installation

Standard air filters only catch large dust clumps, allowing microscopic allergens to circulate through your home. We install high-capacity 5-inch media cabinets that house MERV 16 pleated filters, capturing over 95% of airborne particles, smoke, and mold spores. Medical-grade filtration protects your family and keeps duct interiors clean.

UV-C Germicidal Light Disinfection Setup

Moisture inside dark HVAC evaporator coils creates an ideal environment for mold and bacterial growth. We mount high-output UV-C germicidal lamps directly above the cooling coil deck to sterilize biological contaminants on contact. Continuous ultraviolet disinfection eliminates odors and prevents microbial growth from spreading.

Whole-House Dehumidification & Moisture Control

Excessive indoor humidity fosters dust mite reproduction and mold spore proliferation. We integrate central whole-home dehumidifiers into your existing ductwork to maintain relative indoor humidity between 30% and 50%. Active moisture control improves summer comfort and protects home furnishings from dampness.

Energy Recovery Ventilators (ERV) Installation

Modern airtight homes often trap stale, polluted air inside without adequate fresh air exchange. We install Energy Recovery Ventilators (ERVs) that pull in fresh outdoor air while expelling stale indoor air, transferring thermal energy to conserve heating and cooling. Controlled ventilation keeps indoor air fresh year-round.

Air Duct Video Inspection & Deep Sanitization

Aging duct systems accumulate mold colonies, rodent debris, construction dust, and fibrous insulation particles that recirculate through every room every time the system runs. We deploy a flexible duct inspection camera to video-document contamination locations before applying a hospital-grade EPA-registered sanitizing fog treatment.

Our Step-by-Step Diagnostic and Install Process

1. Particulate Diagnostic Audit

We check current pollution levels using a laser particle counter to measure PM2.5 and PM10 particulate levels. Optical particle scanning measures microscopic dust, pollen, and pet dander suspended in your indoor air. This baseline audit provides clear data to select the correct filtration equipment.

2. Filtration Selection & Install

We mount a high-capacity filter cabinet to accommodate a MERV 16 pleated air filter without reducing HVAC airflow. Medical-grade MERV 16 media filters trap over 95% of airborne pollutants, smoke, and allergens down to 0.3 microns. Professional cabinet installation seals out unconditioned attic air.

3. Sanitizer Setup

We install UV-C germicidal lamps inside the evaporator coil area to neutralize airborne mold and biological contaminants. Continuous ultraviolet light exposure breaks down microbial DNA, preventing mold growth on coil surfaces. Ultraviolet sanitization eliminates persistent musty odors across your duct system.

4. Airflow Optimization

We test draft pressures and balance fresh air intake rates to satisfy California Title 24 Section 150.0(m). Technicians measure total external static pressure to confirm the high-MERV filter does not choke blower fan performance. Balanced ventilation guarantees clean, fresh indoor air in every room.

Frequently Asked Questions

How does a MERV 16 air filter compare to standard filters?

Standard fiberglass filters only capture large dust fibers. A MERV 16 pleated air filter is a medical-grade system that filters out over 95% of microscopic particulates, including smoke, bacteria, and allergens.

What are the Title 24 filtration rules for California homes?

Under California Title 24 Section 150.0(m), all new or replaced HVAC duct systems must be equipped with air filtration systems that accommodate filters with a minimum rating of MERV 13.

How long does a whole-house air quality audit take?

A complete diagnostic audit with particle scanners, humidity tracking, and duct checks typically takes 1 to 2 hours. We provide a full report of findings and custom recommendations.

Can my HVAC system help filter wildfire smoke during Roseville fire season?

Yes. During active wildfire events in the Sierra Nevada and Placer County foothills, your HVAC system becomes your first line of defense. A MERV 16 filter installed in your central air handler traps fine PM2.5 smoke particles that bypass standard filters. We also recommend sealing fresh air intakes and setting your thermostat fan to ‘Recirculate’ during heavy smoke events.

How do I know if I have mold growing in my HVAC ducts?

Common signs include a musty or earthy odor when the air handler runs, visible dark streaks around supply vent grilles, and unexplained allergy or sinus symptoms that improve when you leave the house. Our duct video inspection service uses endoscope cameras to confirm mold presence before recommending UV-C sterilization or professional duct cleaning.

What are VOCs and how do they affect indoor air quality?

Volatile Organic Compounds (VOCs) are gases emitted from household products including paint, new carpet, cleaning products, and furniture adhesives. Long-term VOC exposure is linked to headaches, dizziness, and respiratory irritation. Our Energy Recovery Ventilators (ERVs) dilute VOC concentrations by continuously flushing stale indoor air with fresh filtered outdoor air.

How often should UV-C germicidal lamps be replaced?

UV-C bulbs typically lose 40% of their germicidal output after 9,000 operating hours, roughly 12 months of continuous use. We recommend annual UV lamp replacement during your spring AC tune-up to ensure your system maintains full biological sterilization performance.

What indoor humidity level is ideal for Roseville homes?

The EPA recommends maintaining indoor relative humidity between 30% and 50%. During Roseville’s dry summer months, humidity often drops below 20% indoors, causing dry skin and irritated nasal passages. Our whole-house humidifiers and dehumidifiers maintain this ideal range year-round for maximum respiratory comfort.
