Why is it so important maintain an HVAC system properly designed ?
Because it is the only way of improve the indoor air quality and provides comfort for occupants.
The main purposes of a Heating, Ventilation and Air-Conditioning (HVAC) system are to help maintain good indoor air quality (IAQ), through an adequate ventilation system with filtration and provide thermal comfort.
Keeping those inside comfortable in spite of the outside air temperature also an adequate maintenance program will take care of your system and avoid problems like:
Excessively blown Air (Heating or cooling), it can also cause thermal discomfort.
Spreading bacteria, virus, dust, allergens or other harmful substances.
Inadequate air humidity: causes discomfort, and potentially health issues.
As we know the HVAC system is the responsible for heating or cooling, however there are other many airborne contaminants that linger in the air, such as VOCs (volatile organic compounds), pathogens like viruses, bacteria, and mold spores, as well as allergens. With these airborne pollutants, indoor air quality (IAQ) can decline quickly and pose a significant threat to the health of those inside. Several health conditions are related to airborne pollutants including asthma and other respiratory issues, cancers, and birth defects.
