New homes, schools, office buildings, and more are being built as airtight as possible in an effort to save on energy, and to be able to better control the indoor environment.
But if the indoor environment isn’t properly controlled, contaminants such as formaldehyde, nitrogen dioxide, carbon monoxide (CO), and radon can build up and circulate throughout the house.

Can Poor Indoor Air Quality Affect an A/C System?
In the tristate area July is the hottest month of the year. Averaging at 85°F, air conditioning units are working their hardest.
Small particles like dirt, animal dander, tobacco smoke, dust, pollen, bacteria and more are constantly circulating throughout the A/C unit and hopefully getting caught in the filter. But the more particles captured, the more chances the filter has of getting clogged.
This creates an unhealthy indoor air quality by reducing the airflow throughout your building. The HVAC system is forced to work harder to maintain the same temperature throughout the building and that means something bad for the energy bill –
A/C units also have various cooling parts inside that can be affected by clogging particles.
How to keep A/C units running cool?
One crucial task is to frequently replace air filters. Don’t let make it work twice as hard because it’s going to call it quits.
For areas in which the filters get dirty quicker than normal, one may want to consider adding an air purification system to the problem areas, whether it’s a small portable air purifier like Airfree or a whole-house system like those from Aprilaire.
SHOW A LITTLE LOVE FOR THE HVAC TECHS!
In 2016, National HVAC Tech Day was created by ARS/Rescue Rooter to show appreciation for all HVAC technicians in the industry.
A lot of their work takes place outside so the office environment of a HVAC tech is whatever the weather wants it to be. Extreme heat to rain to cold.
Though it’s not much better if they get to go indoors- From crawl spaces to attics, they may be crawling over debris, dead pests, and mold.
They stay up to date on the newest HVAC technologies and provide regular maintenance to save you from a horrible electric bill. Maintaining efficient HVAC systems help reduce your carbon footprint!
Does your home have hot or cold spots?
Excessive dust?
High utility bills?
Does your building fail specifications for duct tightness?
These are signs of an air leak in your HVAC duct work. ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) says that 75% of all ducts in commercial buildings leak 10-25%. That’s 200-700% higher than ASHRAE’s recommended standard of 3%. Leaks in the return duct spread contaminants throughout the rest of your home or your facility. Leaks in a facility’s ventilation shaft reduces the efficiency of exhaust fans.
Duct Sealing improves indoor air quality from the inside out, repairing leaks with a non-toxic sealant.
Benefits:
- Saves energy.
- Improves comfort and ventilation.
- Helps businesses comply with building codes.

Celebrate National Healthy Homes Month!
June 2017 is the Second Annual National Healthy Homes Month.
Indoor Air Quality has been identified by the Environmental Protection Agency (EPA) as one of the five most urgent environmental risks to public health. HVACR manufacturers, distributors, and contractors are installing more indoor environmental products noticing that IAQ plays a large role in employee health and performance.
People spend most of their time indoors; National Healthy Homes Month offers concepts and tips for keeping those inside spaces healthy and safe.
The theme for this National Healthy Homes Month is Everyone Deserves a Safe and Healthy Home. Each week in June; NHHM will focus on the “Principals of Healthy Homes” with associated set of activities:
- Childhood lead poisoning prevention
- Residential asthma intervention
- Injury prevention
- Smoke free public housing
- Safe indoor pest control
- Radon Safety
- Disaster Recovery
A series of webinars will also be happening throughout the month.
For resources and activities updates, visit the Office of Lead Hazard Control and Healthy Homes.

No one thinks about this certain source of indoor air pollutants because it is the exact opposite of the indoors.
The Outdoors!
If the outdoor air around your home or building isn’t healthy, your indoor air will be affected. If your HVAC outdoor intake is pulling in air near a cooling tower, generator, plumbing vents, garbage etc.…that air is going to be filled with contaminants which is now freely flowing through your house. Even a loading dock upwind can contaminate the air your outdoor intake pulls from.
ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) has a standard to use when putting in HVAC systems. The standard recommends 25 feet between the intake and a cooling tower and a minimum of 15 feet to the nearest dumpster.
So, make sure the outdoor air is clean to help you control the indoor air.
Air is seemingly empty to us because the human eye cannot see many of the particles floating around. Particles can be human skin scales, bacteria, viruses, soot, rust, pet dander, pollen grains, mold spores, car-tire particles and more. Particles can be smaller than .01 micron in size. A micron is one-millionth of a meter, and the human eye cannot see anything under 40 microns.
To put this in perspective, the diameter of a single human hair is about 100 microns.
Household dust can range anywhere from smaller than .01 micron to 10 microns. Mold spores can be 2 microns to 10 microns. Bacteria are normally 0.1 micron to 10 microns and viruses are even smaller. Animal dander can be 5 to 20 microns in size.
So, what does this have to do with healthy indoor environment?
Particles travel on airflows created by HVAC systems and ventilation and, the smaller the particle, the longer it remains airborne. Some are even permanently airborne. The longer it remains airborne, the more time available it can be inhaled deeply into the lungs. Bacteria and viruses carry diseases. Some cause asthma and allergy symptoms. These particles that we can’t see need to be filtered out as much as possible.
Products such as HEPA filters remove 99.97% of particles. Air purifiers can be beneficial but can also be detrimental. An air purifier that ionizes air or creates hydroxyl ions creates an irritating gas to provide that fresh air smell.
The best way to removes these particles is to remove the source altogether. For example, if mold spores are coming off an old rug, get rid of the rug.
