How do you monitor your company's indoor air quality (IAQ)?
For Northern California businesses, maintaining healthy IAQ is a critical investment in the health, productivity, and safety of your employees and customers.
Regional factors like seasonal allergens and wildfire smoke impact our air, so you need a reliable and effective commercial IAQ system. The Ongaro & Sons commercial HVAC team specializes in helping local businesses achieve optimal air quality to create a healthy and welcoming atmosphere.
We work with businesses in Marin, Sonoma, and Napa counties, as well as all the neighboring communities in between. You’ll never go wrong when you call Ongaro & Sons.
Why Is Good Indoor Air Quality Important?
Regardless of what type of business you have, you want to protect the wellness of your employees, customers, and anyone else inside your location. Poor indoor air quality can lead to both acute and chronic health issues.
Harmful particles in the air can originate from many sources. Finding the source and addressing it is the first step in adjusting your air quality.
The second is to contact Ongaro & Sons. For a no-obligation consultation on how we can help improve your company's IAQ, call us at 415-741-2820 or request services online.

What Are the Symptoms of Poor Commercial Indoor Air Quality?
Though a wide spectrum of symptoms can result from poor indoor air quality, here are some of the more prevalent signs:
- Dryness and irritation of the eyes, throat, nose, and skin
- Flu- or cold-like symptoms
- Headache
- Fatigue or lethargy
- Dizziness
- Shortness of breath
- Nausea
- Hypersensitivity and allergies
- Brain fog and forgetfulness
The U.S. Environmental Protection Agency (EPA) explains the term sick building syndrome (SBS) as “situations where building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified.” Poor indoor quality is typically involved.
What Are Common Causes of Indoor Air Quality Problems?
Here in Northern California, our air experts frequently see most indoor air quality problems arising from four situations:
- Contaminants in the indoor air, such as chemicals, mold, gases, dust, bacteria, or odors.
- Poor outdoor air intake.
- Inadequate indoor air environment from poor air circulation, humidity, ventilation issues, and deficient temperature control.
- Lack of routine professional maintenance on commercial heating, commercial ventilation, and commercial air conditioning (HVAC) systems.
