New Post: Summer Cooling – What You Need to Know About R22 The dog days of summer are most certainly in full swing here in the Maryland and Pennsylvania areas, and right about now, we are grateful for our Air-Conditioning (A/C) systems. We rely on these systems to not only cool our homes during the heat of the summer season, but they also help to dehumidify the air inside our homes as an added benefit. Lately, we have been informing our home inspection clients when they have Air-Conditioning systems that use a particular and very common chemical as the refrigerant, often known as R22. R twenty-what, you ask? What the heck is R22 anyway? R22 is a refrigerant chemical used in many Air-Conditioning systems, including Heat Pump systems, which, in the case of an Air-Conditioning system or a Heat Pump system operating in cooling mode, transfers the latent heat from the air inside your home into the R22 refrigerant which then carries the heat to the outdoor unit of your system to be expelled into the outside air. By removing heat from your indoor air, it effectively cools your indoor air and thus makes it more comfortable for you and your family in your home. As the warm, moist air inside your home is blown across the R22-laden evaporator coils inside your system, that air quickly drops in temperature and reaches its dew point, causing the moisture in the air to condense into liquid form on the surfaces of the coils. Your system then collects the liquid water and expels...
