Before you call
Common signs your home may need air-quality help
Indoor air problems are usually felt before they are measured. The fastest way to improve the result is to identify the source first, then choose the right upgrade.
- Dust buildup, stale air, or odors returning quickly after cleaning.
- Allergy, smoke, or humidity issues that seem worse inside than outside.
- Uneven airflow, dirty vents, or comfort problems tied to specific rooms.
Service details
The overview below explains how this service works, common problems we see, and what Sacramento homeowners should expect before scheduling.
The EPA estimates that indoor air is 2–5 times more polluted than outdoor air. In Sacramento, where homes are sealed tight against extreme summer heat, indoor air quality matters more than in more temperate climates.
What We Test
Carbon Monoxide (CO)
CO is a colorless, odorless gas produced by incomplete combustion. Sources include gas furnaces, water heaters, fireplaces, and attached garages. A cracked furnace heat exchanger is the most dangerous common household CO source.
Safe level: Below 1 ppm (indoor background) Action required: Any reading above 9 ppm from appliances
Airborne Particulates (PM2.5 and PM10)
Fine particles from cooking, outdoor pollution infiltration, pets, and duct contamination. PM2.5 particles are small enough to penetrate deep into the lungs.
Sacramento context: PM2.5 levels are elevated during wildfire events and Valley inversions. Understanding your baseline helps you know when to improve filtration.
Humidity Levels
Sacramento's dry climate can drop indoor humidity below 20–25% in summer — causing respiratory irritation and static electricity. Elevated humidity (above 60%) encourages mold growth in HVAC components.
HVAC System Inspection
As part of the assessment, we inspect the air handler, evaporator coil, and accessible ductwork for signs of mold, microbial growth, or contamination that could affect air quality.
After the Test
We provide a written report with our findings and prioritized recommendations. Many air quality issues have straightforward solutions — a filter upgrade, duct cleaning, a UV air purifier, or a combustion appliance repair. We'll tell you exactly what we found and what it means.
Sacramento-Specific Air Quality Concerns
Sacramento homeowners face several air quality challenges that are specific to the region:
Wildfire smoke seasons: The Sacramento Valley is surrounded by fire-prone foothill terrain. Smoke events now occur most years from July through October, sometimes for weeks. During smoke events, PM2.5 concentrations can reach 150–300 μg/m³ outdoors. A well-sealed, well-filtered home with MERV 13 filtration can keep indoor PM2.5 below 35 μg/m³ even during severe events.
Agricultural particulates and pollen: The Central Valley produces heavy spring pollen from almonds, grapes, and trees. Agricultural operations in nearby counties contribute to regional PM10 levels year-round.
Valley inversions: Temperature inversions trap vehicle exhaust, wood smoke, and industrial emissions at ground level — common in fall and winter. During inversion events, outdoor air quality can be worse than during wildfire smoke.
Tight homes and VOC accumulation: Sacramento homes built to modern energy codes are well-sealed. While this is efficient, it also means VOCs from building materials, cleaning products, and off-gassing accumulate without adequate ventilation. An air quality test can identify whether ventilation upgrades are needed.
