Difference Between Central Air Conditioning and Forced Air

Difference Between Central Air Conditioning and Forced Air

April 6, 2022


As a homeowner, you will hear a lot of HVAC-related terms throughout your lifespan. Two of the most commonly used are forced air systems and central air conditioning. While initially, you may believe that these terms are interchangeable, that's simply not the case for several different reasons.

Difference Between Central Air Conditioning and Forced Air

What's a Forced Air System?

Forced air systems are characterized as systems that deliver temperature-controlled air throughout a home via vents and ducting. You'll most commonly hear forced air systems referred to as furnaces or heating systems. While forced air systems include furnaces, they encompass a broad range of heating and cooling systems. You'll want to think of forced air systems as air ducting and vents.

What's Central Air Conditioning?

A central air conditioner provides you with crisp cool air via a closed-loop refrigerant and cycled air system. All central air conditioning systems have three main components: the condenser, compressor, and evaporator coils. The condenser and compressor are located in an outdoor unit, while the evaporator coils are located inside. All three components work in unison to pull warm air in, remove its heat from the outdoors, and redisperse the cooled air back into the rooms throughout your home.

Breaking Down the Differences

The most apparent difference between central air conditioning and forced air is that central air conditioning specifically refers to a cooling system. In fact, central air conditioning is a subset of a forced air system. It utilizes that forced air system to deliver cooled air throughout the ducting and vents in your home.

It's important to think of a central air conditioning system as entirely independent of your furnace. While it does use the same ventilation system as your furnace, a central air conditioning system has an outdoor unit that works to cool your indoor air. A forced air system is simply the air distribution system. Central air applies to the actual air conditioning unit that is used.

After learning the main differences between a forced air system and a central air conditioning system, it becomes clear why these are often interchangeable in conversation.

Proof We’re the Best HVAC Company Straight From Our Customers

  • Didn’t Push a Furnace Replacement
    Taylor D.
    Tom, the owner was awesome. He came out immediately when our furnace went out and completed a challenging fix. When I asked if I should replace the furnace he said no. Honest and did outstanding work. Furnace is quieter and seems to be running better than when we moved in!
  • Highly Recommended for AC Replacement
    Jeremiah D.
    Tom came over and thoroughly discussed my options. We discussed at length the pros and cons of the most expensive and least expensive options, and came up with a fair price for the products I chose. The crew showed up on time and finished the same day, and was easy to deal with. The new furnace heats my house so much better than the old one. I would definitely use Master Mechanical again. And I have. I’ve now replaced multiple furnaces and AC units using Tom and his crew at Master Mechanical, and would use them again.
  • Quick AC Fix During a Power Surge
    Jim P.
    Master Mechanical responded quickly when our AC failed following a power surge. They quickly diagnosed the problem, and responded patiently to my uninformed consumer questions. Once the team arrived to complete the repair work, they were professional and again, knowledgeable. Prices were fair, and they followed up with me after work was completed. Overall a great company!
  • Last Minute AC Repair
    Rupal P.
    Master Mechanical is an amazing company! I called last minute (per my friend's recommendation) since my ac broke yesterday. Victor was friendly, fast and explained everything and he ended up fixing my issue---thank you! Highly recommend Services A/C system repair.
  • Two Great HVAC Experiences
    Bill L.
    Did an excellent job on two repairs. The first was an emergency call for a furnace repair when it was 4 degrees F outside. They showed up on time, diagnosed the problem, went for parts, repaired the furnace all in about an hours time. The second repair was for the whole house humidifier attached to the furnace. It was a minor issue and corrected in less than 40 minutes. Everything is working great. My experience with their work is excellent.
