Air Conditioning 101
Have you ever heard terms tossed around by an HVAC contractor, and wish you knew more? Here is a high level overview of how air conditioning works, so you can better understand your cooling system:

• A thermostat registers the air is too warm. It sends a signal to your system, and the air conditioner and furnace fan both turn on.
• The furnace fan pulls air from inside the home (via the return air duct), and it is pulled through the furnace filter. *A variable speed fan is much quieter, provides more comfort as operates at a higher efficiency.
• The air conditioner (also called a condensing unit) compresses refrigerant, and releases the heat into the air outside. The chilled refrigerant is then sent inside via copper tubing.
• The chilled refrigerant is sent inside to the evaporator coil. An evaporator coil sits on our adjacent to the furnace. Inside the evaporator coil is a series of copper tubing that contains the ice cold refrigerant from the air conditioner.
• The furnace fan forces the air pulled from inside the house through the evaporator coil. This cools and dehumidifies the air.
• The cooled air is sent back into the home via air ducts, and the process repeats.

Heating 101
Heating with a split system works very similar to air conditioning, except the furnace is used as a heat source. When using a heat pump, the heating process is almost identical to the cooling process.

• A thermostat registers the air is too cold. It sends a signal to your system, and the furnace flame begins heating and the fan turns on.
• The furnace fan pulls air from inside the home (via the return air duct) and it is pulled through the furnace filter.
• The heat exchanger is heated via flames powered by gas fuel. The heat exchanger is a metal grid type device inside the furnace.
• The furnace fan forces the air pulled from inside the house through the heat exchanger. This heats and dries out the air. A whole house humidifier can be used to add needed moisture back into the heated air.
• The warm air is sent back into the home via air ducts, and the process continues until the desired temperature is reached.

Indoor Air Quality
Indoor air quality has become a much hotter topic in recent years. Why? Just another way for us to sell products to innocent customers? There actually are substantial reasons to consider indoor air quality solutions for your home.

Modern homes are built to be more energy efficient. Tightly sealed construction means lower energy bills, but more polluted air. In the middle of a Pennysylvania winter or summer, when the windows are all shut, toxins, bacteria and even mold and pet dander get recycled through your HVAC system, and into every area of your home.

Air cleaners, ventilators, UV lights and whole house humidifiers all work together to exchange, refresh and purify your indoor air. IAQ products are designed to each tackle a certain part of indoor air quality, and are not mutually exclusive.

If you need a trusted local Pennysylvania HVAC contractor, you are at the right place. Call us today at (215) 914-1080 for quality that you just cannot live without.
