People usually spend more time indoors especially in the summer under an HVAC unit. They get more exposure to the effect of heating and cooling units. However, if this unit contains air pollutants, it possesses a lot of health risks to the occupants present indoors. Thus, one of the major issues of the HVAC unit is from the perspective of indoor air quality. The contained air in the contained environment remains the same and no recycling takes place. The resultant stuffy air is a warning sign for the occupants. Maintaining the clean ambiance is the need always for which cleaning the HVAC unit and replacing the air filter are highly essential. Replacement of air filters is also necessary for maintaining the efficiency of cooling units. Choosing the right HVAC filter is a tricky issue for people without professional knowledge.
