The 6 Types of Residential HVAC Systems

Have you ever contemplated the idea of upgrading your home’s heating, ventilation, and air conditioning system? Whether you’re seeking a deeper understanding of your current system or exploring new options, we’ve got you covered.

Parrain’s Heating and Air Conditioning stands as Covington’s premier destination for expert AC installation and heating services. Our team specializes in the installation and repair of various residential HVAC systems. Below, we present a selection of the six most commonly encountered HVAC systems within our service areas across St. Tammany Parish.

Heating and Cooling Systems For Your Home: Six Types

#1 Furnace & Air Conditioner

The classic HVAC configuration in many Louisiana households entails distinct furnace and air conditioning systems. Typically, this setup operates by pulling interior air into the system, where it is either heated or cooled, and then efficiently distributed through a network of ducts. For this type of HVAC system, electricity powers the air conditioner unit, while the furnace is typically fueled by options such as oil, propane, electricity, or natural gas.

#2 Ductless Mini-Split

Ductless mini-split systems have gained widespread popularity due to their convenience and efficiency, particularly since they eliminate the need for ductwork. Instead, these systems employ wall-mounted indoor units equipped with built-in air handlers, enabling individualized temperature control for each room.

Each air handler is equipped with its own through-the-wall ductwork, connecting to a dedicated outdoor compressor. This setup grants you enhanced control over distinct temperature zones within your space. However, it’s important to note that installing multiple units is necessary, with one placed in each room as required, which can be a potential drawback.

#3 Heating and Cooling Split Systems

Within a heating and cooling split system, the cooling component resembles a wall or window air conditioner, but it’s integrated with a furnace. This setup allows for the unified control of both the heating and cooling units through a single thermostat. Additionally, there are hybrid split systems available, combining a heat pump and a furnace, which are particularly useful in extremely cold climates (although they are not typically found in Louisiana).

#4 Heat Pump

Heat pumps are experiencing a rapid surge in popularity, and if you’re considering an all-electric HVAC system, a heat pump stands out as a more efficient option than a traditional furnace, especially in warmer states like Louisiana.

What sets heat pumps apart is their utilization of a heat exchange process, as opposed to burning fuel for energy generation. During hot weather, the interior coil operates as the evaporator coil, cooling the air. Conversely, in winter, the process reverses, with the outdoor coil taking on the role of the evaporator, efficiently heating the indoor space.

#5 Central Air Conditioners 

In the past, the prevailing residential HVAC systems were primarily centralized air conditioning units, which operate by circulating air through a supply duct network. While a central air conditioner is distinct from the furnace, it may still share a single ductwork system.

Central air conditioning is renowned for its ability to maintain a uniform temperature throughout your entire home. Nonetheless, it’s important to note that it often comes with lower overall efficiency and entails higher initial installation expenses.

#6 Geothermal Heat Pump

Highly efficient, geothermal HVAC systems operate by transferring heat to or from the earth rather than relying on outdoor air.

But how exactly do geothermal systems function?

An intricate network of underground pipes interfaces with an electricity-powered heat pump. During colder periods, heat is extracted from the earth and directed into the house to provide warmth. Conversely, when it’s warm outside, the system effectively removes heat from the building, aiding in cooling.

The primary downside associated with geothermal systems lies in their substantial installation costs.

Six Choices: Which HVAC System Is the Right Choice for Your Home?

So, when it comes to deciding on the right HVAC system for your needs, there are a few factors to consider. If you prioritize higher energy efficiency and are comfortable with having a unit in each room, a ductless system is an excellent choice. On the other hand, if you already have ductwork in place, a conventional furnace and AC combination can still offer a cost-effective solution.

Regardless of the system you opt for, all HVAC setups require routine maintenance, including:

  • Regular filter replacements.
  • Keeping the condenser unit clean.
  • Clearing drain channels.


These maintenance tasks are essential to ensure your HVAC system operates efficiently and continues to provide optimal comfort. If you sense any issues with your HVAC system, it’s advisable to seek professional assistance promptly.
