“Understanding how a hvac system works is a great way to save money. This holds true whether you own your home or rent a house. You see, having this knowledge can lead to some basic maintenance you can do yourself. This will help avoid expensive hvac repair costs that come with home ownership. Or, can help give you a break on monthly rent if the homeowner can count on your to fix the heating, ventilation, and cooling unit so that he doesn’t have to pay that typically expensive bill.

As a one-time renter and now home owner, I found that knowing how a hvac system works was beneficial for me. You see, I didn’t always have that information. The maximum amount of knowledge I had was that when it was hot outside, I would turn the air conditioner on and temperature down. And when it was cold outside, the heater stole the show and the temperature was raised. Then of course those actions didn’t work, I got on the phone to reach my local hvac repair company. After a couple of calls to them nearly every year, I found out how expensive that course of action can be. Now managing some of my own maintenance based on the knowledge of how heating and cooling systems work keeps more of my own money in my pocket.

Knowing how a hvac system works can give you an idea of how to fix your hvac or at least where to start. And doing so will help keep more of your hard money in your pocket as well so let’s cover the essentials in understanding basic heating, ventilation, and cooling systems.

There are 3 basic components to every hvac system used to control the climate in a home. In simplistic terms, for those who are like I was have little to no clue about heating and cooling systems, the 3 components are the warm or cooled air source, a distribution method for the air has been heated or cooled, and a manner for controlling or regulating the amount of heated or cooled air being distributed. Yes, you would be correct in identifying that manner as the thermostat.

When you put the 3 components in action, here is the scene. Heated air coming from a source such as the furnace and cooled air produced by the air conditioner for example is distributed by use of air ducts. The same air ducts can be used to distribute the heated or cooled air and typically are. The amount of heated or cooled air sent through those ducts is controlled by the thermostat and that is the very basic of how a hvac system works.

(Just as a note, when the hvac unit is not working, any of those 3 components could be the culprit in the crime.)

· While the basics of your heating and cooling unit including the hvac parts and it’s workings have been covered above, there are a few more tips to add to your knowledge base.

· Your home heating, ventilation, and cooling system design is created based on the floor plan of your house. The ventilation and ductwork is laid out to hit every area of your home.

· The air used to cool and heat your home is actually pulled from the environment outside but gets filtered through ventilators the basically clean and disinfect the air brought in.

· A wheel and blower send the air through your hvac unit.

That covers the basics of your heating and cooling unit. With this knowledge you now have a solid introduction to the topic of how a hvac system works.
