I have a 12 year old son that has severe allergies. My home must be kept as clean as possible to ensure that he is as comfortable as he can be throughout the year. One area of the home that I had to learn about was the HVAC system. I had to find out how to keep the air that is circulating through my home as pure of impurities as possible. After spending several days researching the home HVAC system and talking with multiple technicians, I have finally got a handle on how to keep the air in my home clean.
