Except for the 6-8 hours of office work, an average American spends most of his time in their house, breathing the air from their heating and cooling system. But if the airflow from the HVAC System is not healthy and below the standard air quality, you are taking slow poison every second in your home. Most of the time, AC repair isn’t enough. But don’t be alarmed, this is not a permanent situation that you have to be in your whole life. Some minor adjustments and good heating and air conditioning system practices can turn the contaminated indoor air into fresh breathable air and prevent contamination in the future.
