What is the Difference Between HVAC and Air Conditioning?

If you’re looking for ways to chill your commercial spaces, you’ve most likely come across HVAC and air conditioning several times. Though they aren’t exactly the same, these words are frequently used synonymically. Confusing, right?  You’re not alone, Don’t worry, relax! A lot of people question if HVAC and air conditioning (AC) are the same or if there is a genuine difference between HVAC and AC. We will dissect everything in an understandable manner on this blog so you will know exactly what each system accomplishes and which one would be most appropriate for your environment.

Starting with the basics, what is HVAC?

Heating, Ventilation, and Air Conditioning—HVAC for short The wide term “systems used to heat, cool, and ventilate both residential and commercial buildings” applies to Stated differently, HVAC is the whole system for climate control, handling the inside air quality, humidity, and temperature. Whatever the season or the outside temperature calls for them, these systems are absolutely essential for preserving suitable living or working surroundings.

Three main components define an HVAC system:

  • Heating – Usually supplied by a furnace or heat pump, heating warms your house during colder months. The furnace uses electricity or fuels—such as gas or oil—or generates heat from which ducts or radiators distribute the heat throughout the structure.
  • Ventilation – Ventilation is a component of the system that guarantees fresh, outside air may replace the stale, domestic air. Through circulation and filtration, ventilation helps lower pollutants, allergies, and too-high humidity.
  • Air Conditioning – The last piece of the jigsaw is air conditioning, which in warmer months cools the air within your space. It lowers indoor temperatures by removing heat from the air and distributing cooler air all over the construction.

So, in simple terms, HVAC is the umbrella term for the three systems—heating, ventilation, and air conditioning. When people discuss HVAC, they are referring to the complete climate control system rather than only one component of it.

HVAC: What does it do?

While most people are aware of the HVAC advantages—that is, better air quality and climate control—only a few comprehend exactly how HVAC systems operate. An HVAC system must take in air, condition it, and then circulate it if it is to deliver adequate indoor air quality.

Usually, one uses vents or ductwork to intake the air. The space that has to be heated or cooled determines the size and count of vents. It’s time to condition the air once it is being drawn in. The real action of an HVAC system occurs here.

  • The air is first filtered to eliminate pollutants including dust and pollen.
  • The season and the temperature within the structure determine whether it is then heated or cooled.
  • At last, a fan moves the conditioned air around the room.

Starting with a thermostat that detects the air temperature in the space, all these systems follow. Should the thermostat be set to “cool,” the HVAC system will draw air from the surrounding area, lower its temperature, and then blast the cooled air back into the room. Should the thermostat be set to “heat,” the process runs backwards, with the HVAC system drawing cold air and blowing warm air into the room. In both respects, the aim is to raise indoor air quality.

What About Air Conditioning?

When you hear the term “air conditioning,” you are especially referring to the air cooling mechanism. Designed to eliminate heat and humidity from the air within a building, air conditioning systems chill it to a pleasant temperature. AC is actually a single component of an HVAC system.

Though they vary in kind, air conditioning systems all operate on the same idea. An air conditioner—a central air system, ductless mini-split, window unit—absorbs heat from inside the room and releases it outside using refrigerant. This cycle keeps on until the interior air reaches the intended temperature. The main difference between HVAC and AC is that HVAC covers ventilation as well as cooling, whereas air conditioning is just about cooling.

The Role of Air Conditioning in HVAC Systems

If HVAC systems contain air conditioning, you could be wondering: Why do people sometimes refer to AC separately? Excellent question! Although some type of air conditioning is included in every HVAC system, not every one of them counts as HVAC. As an example:

  • Central air conditioning systems: Often with the same ducts and air handler as the heating system, central air conditioning systems are a kind of HVAC system.
  • Window or portable air conditioners: they just cool the space they are put in and lack heating or ventilation; they are not part of an HVAC system. These sections just address air conditioning.

Working hand-in-hand with the furnace, heat pump, or ventilation system, the air conditioning unit of a full-fledged HVAC system offers complete climate control. But when you’re merely speaking to air conditioning on its own, you’re referring to systems that simply chill.

Types of HVAC Systems vs. Types of Air Conditioning Systems

After we have made clear that HVAC is a more general system involving air conditioning, let us now explore some more of the kinds of systems you could come across for both AC and HVAC.

Types of HVAC Systems

  • Split System: Most often used HVAC systems are split systems, which contain ducts to distribute air, a furnace for heating, and an air conditioner for cooling. The term “split” describes the arrangement of the heating and cooling elements—typically with the furnace inside and the AC unit outside.
  • Ductless Mini-Split System: Compared to a conventional split system, the duct Split System is scaled down. It’s an excellent choice for homes without ducts since it doesn’t call for them. Every room or zone receives a mini-split unit so you may separately adjust the temperature.
  • Heat Pumps: Because they may run on electricity and simultaneously heat and chill your house. It operates in a cooling mode much like an air conditioner. Reversing the process, heating mode extracts heat from outside air—even in freezing weather—then brings it indoors.

Packaged HVAC Systems: Usually placed on the roof or outside the structure, packaged HVAC systems comprise one unit housing all the components—heating, cooling, and ventilation. Commercial environments find great popularity for these systems.

Types of Air Conditioning Systems

  • Central Air Conditioning: widely included in a more extensive HVAC system, central air conditioning is the most widely used cooling system. It cools the whole space or building from one central unit using a duct system.
  • Window Air Conditioners: Little, self-contained devices meant to chill one room are window air conditioners. Sitting in a window frame, they blow cool air inside and exhaust heat outside.
  • Portable Air Conditioners: Like window units, but transportable, portable air conditioners can be carried from one room to another. They also have to drain heat through a window close by.

Ductless Mini-Splits: As was already noted, ductless mini-splits can cool and heat separate areas of your property. In areas lacking ducting, they are great.

So, How Do You Choose Between HVAC and Air Conditioning?

Your particular needs will determine which HVAC or air conditioning you need. If you simply need to chill a small area, a basic air conditioner will be enough. But since an HVAC system will provide heating, cooling, and ventilation, it is the superior choice if you wish to control the temperature of your whole house year-round.

For people who live in places with harsh weather—such as sweltering summers and cold winters—an HVAC system is absolutely vital. It improves air quality and keeps your house comfortable all year round. On the other hand, if your temperature is mild and heating is rarely required, you might find that an air conditioner will be sufficient for the hotter months.
