Air Quality

There are things you know, things you know that you don’t know (I know that I don’t know how to fly a plane), and there are things you don’t know that you don’t know.


One of our clients didn’t know she had POOR air quality in her home. She suffers from seasonal allergies, but aside from that figured her home was clean and healthy. From a visual perspective it is very clean! She has espresso brown floors and two story bay windows that pour in bright sunlight. Even still, there isn’t a spec of dirt, a footprint, or a strand of dog hair to be seen. I have similar floors in my home, believe me, the-struggle-is-real


During a recent service appointment to fix her a/c we checked her air quality. When you visit the doctor they always check your blood pressure. When we visit your home we check the air quality. The air quality in her home was not good! Here are the before and after photos of her air quality. You may not have known Hot 2 Cold has a staff of air quality experts that nerd out on providing you with the freshest, cleanest air possible

Is the air in my home good? Should I spend hundreds to have it tested or just make
Historically, testing the air quality in your home costed hundreds of dollars and could take up to
one month to receive the results. Also, running one test only offers a snapshot in time. In the
moments of testing the air quality might be exceptionally good, or bad. The variables that
contribute to the air quality in your home can change rapidly. So, while we were testing a home
we hoped the problem would be present in those moments. Have you ever taken your car in
because it was making a noise, but the noise went away while you had it in the shop? In years
past, our advice has leaned toward discouraging the air testing and instead spending the money
on the improvements we knew would make a difference. Now we have a different approach, air
quality monitoring.
Thanks to technological advancement its no longer hard, or expensive, to continuously test and
monitor the health of your indoor air. We purchased two over-the-counter air quality monitors
and compared them to our professional testing equipment. To decide which one is best for you
lets uncover the major variables that contribute to clean or unhealthy indoor air.
Humidity – a relative humidity of 30-50 percent is recommended
CO2 – 400-800 ppm is recommended in an occupied structure
VOCs – less than or equal to (≤) 0.5mg/m3
Particulate – There are many different sizes of particulates, but the EPA recommends the levels
be the same or lower than outdoors.
The two products we compared are the AWAIR Element and the AIRTHINGS Smart Indoor Air
Quality Monitor. These devices are continuous air quality monitors. Both devices test the
temperature, humidity, and VOCs. The AWAIR Element monitors a few more variables, the
carbon dioxide (CO2) and particulate matter.
Both units are easy to set up and have easy-to-use phone apps to view the data. When we
compared the monitors to our testing equipment they were both accurate and fell within the
specified tolerances. Our favorite of the two… the AWAIR Element. This device shows real-time
information. It constantly monitors the air quality variables listed and provides a “score” on the
face of the device and in the app. The AIRTHINGS product works well for averaging the
temperature, humidity, and VOCs over time, but it does not provide the moment by moment
numbers that we find the most helpful when trying to resolve an air quality problem.
If you’re in the market for a continuous air quality monitor get it quick. From the time we
purchased the units in September 2020 to now, November 2020, the prices have come up
nearly $100. For information on your indoor air quality get in touch with us for a home
