How does one of these systems operate? It’s important to comprehend how different heating and cooling distribution systems function. You will comprehend your HVAC system more fully as a result of this.

Types of Systems

Forced Air Systems

A blower is used in a forced air system to push hot or cold air through metal ducts. Depending on whether you’re using the air conditioner or the furnace, hot air is blasted through one set of ducts while cold air is pumped through a different set of ducts.

Blowing out is the most frequent issue with forced air systems. The blowers may develop problems toward the end of their useful lives and stop functioning. Also typical are volume concerns with less expensive systems.

Gravity Systems

The idea behind gravity systems is that cold air sinks, and hot air rises. Consequently, combining a gravity system with an air conditioning system is impossible. The basement is where these systems are located. 

Radiant System

The same issue that affects gravity systems also affects radiant systems. You cannot combine them with air conditioning units. A room’s ceiling, walls, or flooring can all be heated with a radiant heating system.

However, they are most frequently used to warm objects like radiators, which disperse heat around your space. Radiant systems’ main drawback is that the pipes carrying hot water are prone to breaking down due to mineral deposits or normal wear and tear.

How Does An HVAC System Work?

For an HVAC system to function, heat must be transferred from one area of the house to the outside air using refrigerant. Summertime is when this occurs. In the outside unit’s compressor part, the refrigerant is initially compressed. It is now liquid.

It is carried out in the HVAC system’s condenser, or external, part. Condenser coils carrying the refrigerant are cooled by fans blowing across them. The liquid refrigerant is expanded quickly by an expansion valve, which is the next step in the process, turning it into a chilly gas.

The gas is sent through the evaporator’s coils, where it picks up heat from the interior air. These coils are cooled by the room air that is blown over them by a fan. As a consequence of heat absorption, the refrigerant is now hot and is once more transported through the compressor, continuing the cycle.


You might be surprised to understand how simple your HVAC system is. It is merely a heater and air conditioning system together. Your thermostat’s brain regulates how it operates. Make sure to complete your research in advance if you’re considering installing a new system in your home or AC repair in Surprise.
