Indoor Air Quality

A home temperature control system normally has good air filtration, but those with allergies and sensitivities may require maximum air quality protection.



Indoor Air Quality: an important HVAC consideration

In the last several years, a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities. Other research indicates that people spend approximately 90 percent of their time indoors. Thus, for many people, the risks to health may be greater due to exposure to air pollution indoors than outdoors.

In addition, people who may be exposed to indoor air pollutants for the longest periods of time are often those most susceptible to the effects of indoor air pollution. Such groups include the young, the elderly, and the chronically ill, especially those suffering from respiratory or cardiovascular disease.

Cleaner indoor air improves cognition and productivity, reduces the spread of other airborne diseases, protects against outdoor air pollutants such as smog and wildfire smoke, and decreases the number of environmental triggers for conditions like asthma and allergies.

Whole home clean air solutions involve multiple systems, settings, and maintenance schedules. Setting and keeping the air in your home within an ideal humidity and temperature range, regular heating/cooling system and filter maintenance, optimal fresh air circulation, as well as possible indoor air quality enhancements like air cleaners and annual duct cleaning all contribute to the best possible reduction of allergens, odors, and contaminants, and viruses in your home.
