How do you monitor your company's indoor air quality (IAQ)?

For the North Bay 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 Common Causes of Indoor Air Quality Problems?

Here in the North Bay, 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.

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.

Why Ongaro & Sons for Commercial Indoor Air Quality

For a commercial building, air quality is a ventilation and filtration engineering question, not a product purchase.

Schedule Service →
Ventilation rates checked against the actual occupancy

Outside air requirements follow use and occupancy. A space that changed tenant frequently no longer meets what it was designed for.

Filtration matched to what the equipment can carry

Upgrading filters without checking static pressure starves airflow and shortens equipment life. We measure before recommending.

Economisers actually verified

Economisers fail quietly and are rarely checked. A stuck damper wastes energy year-round and nobody gets an alarm.

Smoke events planned for in advance

North Bay buildings need a filtration and recirculation plan before the smoke arrives, not during it.

Serving North Bay businesses since 1932

Ongaro & Sons has maintained commercial ventilation equipment across Marin, Sonoma and Napa since 1932, from its Petaluma headquarters.

Frequently Asked Questions

How do I know if it is time to replace my commercial HVAC system?

Typically, well-maintained commercial HVAC systems last around 15 years. However, if you notice rising energy bills or frequent repair needs, it might be time to consider new, energy-efficient equipment. That way, you can enjoy maximum efficiency and comfort for your customers, guests, and employees while reducing your monthly heating and cooling costs.

How often should I maintain my commercial HVAC equipment?

Regular maintenance is crucial to keep your system running efficiently and to maintain your warranty. It’s akin to regular oil changes for a vehicle. Your air conditioner and furnace should be inspected and maintained annually.

Is it better to repair or replace my commercial heating and cooling system?

Generally, repairs might be the best option if your commercial HVAC system is relatively new or the damage is minor. However, upgrading to a new system might be more economical and efficient for more severe issues, especially those not covered under warranty.

What are the advantages of professional commercial HVAC maintenance?

Benefits of professional HVAC maintenance include inspection, cleaning, and prompt resolution of potential issues. Regular maintenance can improve your commercial HVAC system’s energy efficiency. According to the U.S. Department of Energy (DOE), commercial buildings consume 40 percent of the energy used in the United States . Imagine reducing a portion of that and how much you could save in heating and cooling costs each month! Ask us about a customized maintenance plan tailored to your business needs and budget. Maintenance plans offer a hassle-free way to care for your HVAC system and avoid unexpected repairs.
