Indoor air quality is important to our health, learn more at the CPS Blog.More people need to ask this question. As an HVAC contractor, husband, and father of four children, I take indoor air quality seriously. The health impacts of poor indoor air quality can be very harmful when they go untreated. Unfortunately, most people don’t have conversations about indoor air quality and good ventilation even when they’re suffering from tell-tale signs.CPS Heating & Cooling handles everything from ductless mini-split heat pumps to energy-efficient central air conditioning systems. Heating and cooling repair is just part of our business.

Americans spend an average of 87% of their lives indoors, according to the National Human Activity Pattern Survey (NHAPS) conducted by Environmental Protection Agency (EPA). So, it makes sense that the quality of our indoor environments greatly impacts our health.

To help you give your home or office a preliminary diagnosis, I put together an easy-to-use checklist for assessing the conditions of your indoor environment. The expert guidance in this article is meant to help you determine if you need to hire a professional HVAC technician.


Indoor air quality has been comprehensively studied by the National Institute for Occupational Safety and Health (NIOSH), which is part of the U.S. Centers for Disease Control and Prevention. NIOSH found concentrations of some pollutants can be up to 5 times higher indoors than typical concentrations of the same pollutants in outdoor environments.

A building is considered “sick” by NIOSH if 20% of the workforce presents any of these symptoms:

  • Watering eyes
  • Hoarseness
  • Headaches
  • Dry, itchy skin
  • Dizziness
  • Nausea
  • Heart palpitations
  • Miscarriages
  • Shortness of breath
  • Nosebleeds
  • Chronic fatigue
  • Mental fogginess
  • Tremors
  • Swelling of legs or ankles
  • Cancer

SELF-HEALTH TIP: If you suffer from any of these sick-building symptoms, take notes on whether your symptoms ease or clear up when you leave the suspected building.


Poor indoor environmental quality also presents itself in problem areas of a building, according to the SmarterHouse project by the American Council for an Energy-Efficient Economy. In New England, there are typically two types of building symptoms:CPS Heating & Cooling has the nearby heating and cooling technicians to help you cut your energy costs. Affordable HVAC supplies come with factory-trained HVAC technicians.

  • Too much air flow—You can feel drafts indoors during winter, especially near windows, doors, HVAC vents, and exterior walls. Also, low humidity levels cause frequent static electricity discharges.
  • Too little air flow—Odor is a great indicator. Is there a musty, mildew smell? Do common odors, like food or perfume, hang around a long time?


What are we cleaning from the air? There are a lot of gases, particles, and organisms floating around in the air. Not all of them are toxic to us. However, when you want a sanctuary for your family, or a highly productive workspace for your employees, you want the highest quality air. Leading HVAC equipment manufacturers offer many different types of affordable filters that specifically fit their HVAC systems to clean pollutants caused by:

  • Office equipment
  • Cleaning products
  • Carpets and furnishings
  • Perfumes
  • Fungus, mold, and bacteria
  • Nature (pollen, insects, and rodents)
  • Dampness
  • Volatile organic compounds (VOC)CPS Heating & Cooling offers competitive HVAC technician salaries. We help our technicians get HVAC certification in a variety of areas, including up-to-date NATE certification.

SELF-HEALTH TIP: When choosing the best air filter for your HVAC system, think about the needs of the indoor space and the people using it. The most important detail to remember about a filter is to change it regularly.
