Ever wondered what makes your HVAC run? Here's some insight into your heating and cooling system!

Everything requires moderation. Whether it is during the hottest days of summer or in the dead of winter in Nashville, it is human to want to moderate the temperatures. Despite us relying on our HVAC for comfort, many don't understand how the system works. If you want to learn more about HVAC systems, read the following blog for insight!

How do different HVAC systems work?

Gravity systems rely on the principle that cold air is heavier than hot air; thus will be at the bottom while hot air rises. Thus, it is not possible to use gravity systems alongside air conditioning systems. They are usually placed in the basement. When you switch it on, warm air goes to the ceiling and heats your house, and when it cools, it sinks and is reheated.

Forced air systems usually takes cold or hot air and pushes it through metal tubes using a blower. Hot air and cold air is forced through different channels subject to whether you are using the furnace or air conditioner. The major drawback of forced air systems is blowouts. With time, the systems undergo tear and wear which can cause the malfunctioning of the blowers.

Radiant systems also have a similar drawback as the gravity system; as they cannot be used alongside air conditioning systems. Radiant heating systems are used to heat all parts of the house, but most commonly, they heat implements that distribute the heat around your home such as radiators.

The following is a list of HVAC parts and how they work:

For you to understand how heating and cooling systems work, you need to know how their parts work. Regardless of the model, these systems comprise of four major parts.

The air conditioner handles cooling the air and is usually placed outside the building. It utilizes either a coolant liquid or electricity to lower the temperature of the air. When it is switched on, it sends cold air inside and hot air outside.

The thermostat controls the system. Usually, it turns the system on or off and controls the temperature. It also operates specialized features that are installed in some heating and cooling systems.

The ductwork consists of channels that enable the transition of cold and hot air in the home. It is fixed in the interior of the building.

The furnace uses various heat sources such as oil or natural gas to heat the air. There is a heat exchanger inside the furnace which maintains the air at the required temperature. Usually, the heater is placed in the basement, attic or inside a specially designed cabinet.
