Indoor Air Quality Test in San Francisco, CA

Indoor Air Quality Test in San Francisco

The only difference between the air in your lungs and the one outside of them is its location. This is why indoor air quality is so important. While we can’t have full control over the air quality when outdoors, we do have control over the one indoors. And this is where GCD Restoration’s air quality testing services for San Francisco Bay Area come in to play.

Make Indoor Air Quality Testing A Priority For The Rainy San Francisco Season

HVAC systems (Heating, Ventilation and Air Conditioning) are a San Franciscan’s main source of air cooling and heating. It’s an intricate network of air ducks distribute cooled or heated air throughout a property.

This network  is circulating indoor air and expelling excess heat or moisture outside, picking up dust and fine particles, depositing them into the air vents and air ducts of the property.

Air current and circulation will disturb deposited particles and dust, bringing them back into the room, contributing to poor indoor air quality and intensified room pollution. A regularly scheduled air duct cleaning will make property maintenance and dusting a lot easier. In addition it will alleviate any respiratory issues or allergy-like symptoms

While such a system is quite convenient for creating a standardized indoor climate, it requires routine maintenance and air quality checks to see how it’s performing. Information gathered through air tests is an indication of the pollution of the air ducts.

Such pollution is inevitable, though it will result in the lowering of efficiency of your HVAC system. Prolong the longevity of your air conditioning with GCD Restoration’s routine air duct cleaning.

Which Are The Most Common Air Duct Pollutants?

San Francisco resident’s HVAC systems are more prone to mold and mildew growth. With The Mediterranean-like climate of the Bay Area, and an average annual humidity rating of 75%, it’s quite expected.

This introduction of moisture into the air provides perfect breeding conditions for fungi, especially during the rainy 5 months from March to early October.

Some common substances and microorganisms that may be contaminating the air in your residential or commercial building include:

  • Mold and Mildew
  • Fungi
  • Dust, Pollen, and other micro-particles
  • Asbestos, lead, radon, and other hazardous building materials
  • VOCs (volatile organic compounds), pollutants found in paints, cleaning products, air fresheners, and other household chemicals
  • Carbon monoxide
  • Secondhand smoke

Any of these may be a factor for the decrease of air quality and the introduction of unpleasant smells. They may also be main contributors for poor health, allergies, sleep apnea and other issues.

Side Effects Of Poor Indoor Air Quality

Air quality testing is vital for the proper diagnosis of many health issues.

If you are experiencing any of these, please check with your doctor and give GCD Restorations a call for immediate assistance. All of these may be the cause of poor air quality and airborne pollution:

  • Shortness of breath or other respiratory issues including asthma and bronchitis
  • Allergic symptoms such as skin irritation, itching, rashes, swelling, or stuffy or runny nose and sore throat
  • Fatigue or headaches, migraines, lethargy
  • Nausea or diarrhea, upset digestive tract


The extent to which you are affected depends on your immune system and how it responds to outside intrusion.

If you are noticing that the symptoms described above persist only when you are indoors, and subside when you step outside, it is a sure sign that your HVAC system is due for a cleaning.

How to Test Air Quality in Your Home

There are cases where the services of air quality testing companies are not yet required. If you want to do an air quality check, there are several things that you can do. Here are just some of them:

  • Buy a home air quality test kit from the pharmacy;
  • Place a paper towel on-top of went covers to see the condition of the air flow;
  • Check the immediate vicinity of the air vent covers.

The paper towel trick is a useful tool which will provide you with a visual representation of the conditions of your breathable air. It is a quick form of air quality inspection which takes 1 day to complete.

Place the paper towel on top of any vent cover and use duct tape to seal it well. The porous texture of the paper towel will still allow air to pass, but will still be able to catch any large particles.

Remove and inspect the paper 24 hours after you’ve placed it – if it’s dirty then it might be time for an air quality test from professionals.
