A Heating and Air Conditioning unit is not as complicated as some people would assume, as a matter of fact, a normal person can understand it. Here is the simple outline of an air conditioning unit. The unit itself sits outside the house and looks like a giant box. The air conditioning unit works by taking the air around it and using coolant and electricity, it cools down the air. Then the air conditioner blows the air into the already installed air vents that run through the house. The air vents blow both the furnace and air conditioning air. The furnace method is similar to the cooling system because the furnace also takes normal air, heats it up, and sends it to the air vents. While the air conditioner is outside, the furnace is in the basement or attic. The heating system properly will run on gas or oil and will dispense the warm air through the home using the installed air ducts. The temperature control, also known as the thermostat, is what controls both the air conditioning and the heating system. It is the motherboard of the HVAC unit. The best part is that you get to control the motherboard by using the thermostat. To install an HVAC system in your home is simple and quick. You just need to contact your local HVAC store and set a date to have your air ducts, air conditioning unit, & heating system installed. Within a few days, the HVAC workers will be at your door ready to install your HVAC system for you. From that time on you can have optimal comfort in your home.
