Dry Air, Indoor Air Quality & Your Health

January 27, 2022 by Michael Rosone | Last Modified: January 19, 2024

We tend to think about high humidity as a problem that impacts both our health and our comfort. However, dry air (caused by low indoor humidity) can cause just as much discomfort as humid air. In fact, recent research suggests that prolonged exposure to excessively dry air can even cause elevated stress levels.

Dry air may also compound the impacts of other indoor air quality problems. Some studies have shown that dry air increases the negative effects of high levels of particulate matter and VOCs. 

It’s worth paying attention to the relative humidity levels of the air you breathe, especially since most buildings are not monitored or controlled for humidity levels that are too low. There isn’t even consensus on what constitutes air that’s too dry, but many experts recommend optimal humidity levels between 35 and 60 percent.

Don’t Ignore These 5 Signs of an AC Refrigerant Leak

September 12, 2017 by Michael Rosone | Last Modified: August 15, 2023

ac refrigerant leak

Are you are concerned because your place is not cooling off like it should? Perhaps you’ve noticed warm air or lower than normal airflow coming out of your system’s registers or you’ve heard a hissing sound. Maybe you’ve observed water on the floor by your HVAC unit or seen ice forming on your evaporator coils. These are all telltale signs of an AC refrigerant leak.

IMPORTANT: Losing refrigerant is not normal and likely signals an AC refrigerant leak. A properly running system maintains the same amount of refrigerant. It’s not like oil in your car that must be replenished over time.
