How Does an HVAC System Work?

Whether your HVAC system is located in your basement or in a utility closet on the main level of your Glendale home, you probably never give it much thought. What’s interesting is that while you’re living your everyday life, your HVAC system is working hard to ensure you stay comfortable through it all. When you dig into it, an HVAC system is actually quite sophisticated and fascinating. Here is a basic explanation of how HVAC systems work.

The Blower Fan: The Heart of the System

If your HVAC system has a “heart,” then it’s definitely the blower fan. The blower fan pulls in the air for both the furnace and the air conditioner, pushing that air over the heat exchanger or the evaporator coils before distributing the air throughout your home. This means that while your HVAC system is running, your blower fan is spinning. It’s important to maintain your blower fan regularly.

Changing the Temperature

Moving air is great, but it doesn’t mean much unless that air is helping to heat or cool your home; that’s where your air conditioner and furnace come in. Your air conditioner operates by moving the refrigerant through a series of tubes to cool the refrigerant. When the refrigerant passes above the blower fan in the evaporator coils, the heat is removed from the passing air, thus cooling down your home. This heat is then removed by the condenser and released into the outside air.

The furnace, on the other hand, relies on either a gas heat exchanger or coils in an electric furnace, to reach a higher temperature. When air passes over these hot components, the air also increases in temperature, thus warming your home. At Christian Brothers Air Conditioning, Plumbing and Electrical, we understand each of these components to ensure they’re operating as they should.

The Ducts: Unseen Heroes

The last step in heating or cooling your home is to move the air to the various rooms. This is the job of the ducts. Ducts are simply large pipes that direct air where it’s needed. To do this effectively, ducts must be clean and airtight. At Christian Brothers Air Conditioning, Plumbing and Electrical, we can assess your ducts to ensure they’re moving air efficiently and make any repairs if problems are discovered.
