September 20, 2021


Indoor air quality has remained a significant problem in many homes. Sometimes the air we breathe can be more dangerous than the air outside our house, making it essential to know how indoor air quality is measured. We will discuss the factors that contribute to poor indoor air quality and how you can measure your indoor air quality at home!

How is Indoor Air Quality Measured?

Sources of Indoor Air Quality Problems

Radon gas

Radon is a naturally occurring radioactive gas. It forms from the natural decay of uranium in soil and rock and can seep into homes through cracks in foundations or sump pumps.

Carbon monoxide

Carbon monoxide is a colorless, odorless gas that results from incomplete combustion through heating sources such as fireplaces and furnaces. If you smell a "rotten egg" odor in your home, chances are it's coming from an outside gas source.

Volatile Organic Compounds

Volatile Organic Compounds (VOCs) are chemical substances that evaporate quickly and efficiently into the air, causing an indoor air quality problem. Many household products contain VOCs, including paint, cleaners, perfumes, candles, et cetera. After these chemicals are vaporized into your home's air, they can mix with gases like radon and carbon monoxide.

Methods for Measuring Indoor Air Quality

  • Carbon Monoxide Test Kit: Carbon Monoxide is a hazardous gas that can enter your home undetected, especially if you have any heating appliances in use. To measure the amount of CO in your home, you can purchase a CO test kit from local stores like Home Depot and Lowes.
  • Air Quality Monitor: If the above test comes back negative for CO, a carbon monoxide detector will effectively detect indoor air pollution, which involves any gases or vapor that contribute to poor quality indoor air. When buying an air quality monitor, be sure to choose one with a digital display and alarm for your convenience. Even monitors can measure several common household gases, ranging from humidity levels, radon gas, VOCs, and more.
  • Duct Calculator: If you suspect your home's air ducts have been damaged by water or insects, you may consider having them checked by an HVAC professional. You can also run a duct calculator and check for potential problems yourself.

Proof We’re the Best HVAC Company Straight From Our Customers

  • Didn’t Push a Furnace Replacement
    Taylor D.
    Tom, the owner was awesome. He came out immediately when our furnace went out and completed a challenging fix. When I asked if I should replace the furnace he said no. Honest and did outstanding work. Furnace is quieter and seems to be running better than when we moved in!
  • Highly Recommended for AC Replacement
    Jeremiah D.
    Tom came over and thoroughly discussed my options. We discussed at length the pros and cons of the most expensive and least expensive options, and came up with a fair price for the products I chose. The crew showed up on time and finished the same day, and was easy to deal with. The new furnace heats my house so much better than the old one. I would definitely use Master Mechanical again. And I have. I’ve now replaced multiple furnaces and AC units using Tom and his crew at Master Mechanical, and would use them again.
  • Quick AC Fix During a Power Surge
    Jim P.
    Master Mechanical responded quickly when our AC failed following a power surge. They quickly diagnosed the problem, and responded patiently to my uninformed consumer questions. Once the team arrived to complete the repair work, they were professional and again, knowledgeable. Prices were fair, and they followed up with me after work was completed. Overall a great company!
  • Last Minute AC Repair
    Rupal P.
    Master Mechanical is an amazing company! I called last minute (per my friend's recommendation) since my ac broke yesterday. Victor was friendly, fast and explained everything and he ended up fixing my issue---thank you! Highly recommend Services A/C system repair.
  • Two Great HVAC Experiences
    Bill L.
    Did an excellent job on two repairs. The first was an emergency call for a furnace repair when it was 4 degrees F outside. They showed up on time, diagnosed the problem, went for parts, repaired the furnace all in about an hours time. The second repair was for the whole house humidifier attached to the furnace. It was a minor issue and corrected in less than 40 minutes. Everything is working great. My experience with their work is excellent.
