Air Conditioning and Furnace Know how

by Kevin Smith Author

It’s almost unthinkable. A house without air conditioning. But many older homes, built prior to the 1970s, do not have central air. Back in the day, they just opened the windows and turned on fans.

If a house was not built for air conditioning, an air conditioning unit can be added to a house. The air will be circulated through the heating ducts, so getting cool air from room to room is not an issue. The additional equipment needed is an air conditioning coil that gets mounted on top of the furnace, and an air conditioning condenser, which sits outside the house. Installing air conditioning is not something you can do yourself. You’ll need to call in a professional for air conditioning installation in Villa Rica.

How AC Works

Air conditioning works as a refrigerant, known as freon or Puron, travels in copper tubes that connect to the air conditioning condenser outside the house. The copper tubes are directed inside the house through the walls and connect to the air conditioning coil. The air conditioning coil is housed in a metal box that sits directly atop the furnace. The refrigerant in the copper tubing captures the heat in the coil and sends it to the air conditioning condenser outside to cool it down. By removing the heat from the coil, the coil remains cool where air can blow past it carrying the coolness through the house. In the air conditioning condenser outside, the fan spins cooling the hot refrigerant. Once cool, then the cool refrigerant travels inside the copper tubing through the house to the coil where it cools the coil.

If you don’t feel cold air coming out through the vents, it’s a problem with your coil, your copper tubing, or your AC condenser outside. If no cold air is coming out call in a professional to discuss air conditioning installation in Villa Rica.

Heating Breakdown

Heating equipment is less complicated. Gas furnaces create heat when gas is ignited in a heat exchanger. To turn on the furnace, raise the temperature on the thermostat and a signal is sent to the heat exchanger to fill with gas and ignite. As hot air is generated, you’ll feel it coming up the vents. When a house reaches the temperate you set on the thermometer, the heat exchanger stops until the temperature falls several degrees.

If you don’t feel the heat coming out it’s a problem with the gas line sending enough gas or the heat exchanger is faulty. You can check to see if the heat exchanger is igniting by removing the panel on the front of the furnace and watching to see if the gas is ignited. Most likely there is an issue with the heat exchanger and you can call in a professional.
