  • If you have the right HVAC system for your needs, it can easily last you several years or even decades, given that you take care of it.
  • Here is a quick overview of some common issues that HVAC owners face and some simple fixes for them.
  • The outdoor unit of the HVAC is exposed to the elements more than any other part.
  •  Window units are comparable to room air conditioners.

At Sharon’s Heating and Cooling, we recognize that choosing the right HVAC (Heating, Ventilation, and Air Conditioning) system for your home can be a difficult and costly endeavor. We will break down these systems to give you a better understanding of the various HVAC system types and help you make an informed decision. You will also learn the advantages and disadvantages of these cooling systems and the benefits of making an informed choice.

Types of HVAC Systems

As a homeowner or business owner, understanding the different types of HVAC systems is essential. There are three (3) types of HVAC systems: central air conditioning, room air conditioners, and window units. 

  • Central Air Conditioning

Central air conditioning is the most common type and is typically found in bigger homes and businesses. It works by sucking in cold air from outside and blowing it through the house to cool it down. 

Controlled by a thermostat, central air conditioning systems can be set to different temperatures for different rooms. This means that every room in your home will be cooled uniformly, and you won’t have to worry about hot spots. With proper care, these systems can last longer and require little maintenance.


  • Evenly cools the entire house.
  • Requires low maintenance.
  • Durable with proper care.
  • Energy efficient.
  • Disadvantages:
  • High initial cost.
  • Requires ductwork.
  • It can be noisy.

Room Air Conditioners

As their name suggests, room air conditioners cool a single room. They are ideal for small apartments, dorm rooms, and other rooms where only a small amount of space needs to be cooled. 

These units are typically smaller and more portable than central air conditioners, blowing cold air through a small hose into the room. Room air conditioners are easy to install, making them a great option for renters or those who do not want to commit to a central air conditioning system for an extended time.


  • Cools a single room or specific areas of the house.
  • Portable and easy to install.
  • Ideal for renters or those who do not want to make a long-term investment.
  • Disadvantages:
  • Not as energy efficient as central air conditioning.
  • It can be noisy.
  • Venting hot air requires a window or a hole in the wall.

Windows Units

Window units are comparable to room air conditioners. They cool a single room but work by blowing cold air into the room through a large window unit. Window units are simple to install and remove when not in use, making them a popular choice for renters or those unwilling to invest in a more permanent HVAC solution.


  • Affordable.
  • Simple to install.
  • Ideal for cooling a single room.


  • Not as energy-efficient as central air conditioning.
  • It can be noisy.
  • Require a great deal of space.

In addition to the three most common types of HVAC systems, there are a few variations to consider.

The first is a ductless mini-split system. This system is a hybrid of central air conditioning and room air conditioning units. It comprises an outdoor unit connected via a small conduit to one or more indoor units. This enables you to cool specific areas of your home while enjoying the benefits of a central air conditioning system. In addition to being energy efficient, ductless mini-split systems can help reduce your energy costs.

Heat pumps are an alternative to consider. A heat pump is a heating and cooling system it transfers heat from one location to another instead of generating heat. This makes it a particularly energy-efficient option in mild climates. Heat pumps can function independently or in tandem with a furnace or air conditioner.

Geothermal systems are also an efficient and sustainable option. This HVAC system uses the earth’s constant temperature to heat and cools a building. A fluid is circulated through a buried loop system that absorbs ground heat during the winter and releases it during the summer. Geothermal systems are more difficult to install but could save you money on your energy bills.
