Products and Services
Air Conditioning
When most of us think about air conditioning, we think about an air conditioner and refrigerant cooling the air in our home. This actual process of air conditioning starts when refrigerant passes through the evaporator coil. As it passes through the coil the heat is removed from the air. The humidity in the air condenses on the cold surface of the coil and drains away. What this means to you, is the air is now cooler and drier making your home more comfortable.
Indoor Air Quality
Indoor air quality is a very important part of your home comfort system. Did you know that indoor air is generally 5 times worse than outdoor air? Over 35 million suffer from seasonal allergies and approximately 20% of all Americans suffer from sinuses or allergies.
