HVAC Size Matters

When it comes to your HVAC, it might surprise you to know that one size doesn’t fit all. There are different types of systems that work well in larger spaces, and others that work better in smaller spaces. The way in which you heat and cool your home, and your lifestyle also plays a factor in your choice of system.

With this in mind, choosing a system for your home can be intimidating. Fortunately, the professionals have got you covered. Read on for DG Heating & Air Conditioning’s tips on which system will work best for your heating and cooling needs.


The size of your home will correlate directly with the size of your HVAC system. If your system is too large, you run the risk of excess moisture build-up that can cause mold growth and leaks. It can also cause the cool air in your home to have a humid, almost clammy feel to it.

If your system is too small, however, your home will not be heated and cooled evenly and you will likely see an increase in energy consumption.

One of the best ways to determine the correct size for your home is to look at:

  • Square footage of the home.
  • The climate zone you live in.
  • The number of windows in your home.
  • How much natural sunlight the home gets.
  • Insulation levels of the home.
  • The number of rooms/people living there.

This is a lot to consider, which is why we always recommend seeking the help of a professional to find your perfect HVAC system.

Type of System

Now that you’ve sorted out the size of your system, it is time to look at the different types of systems you could install. Let’s take a look at four of your options:

Packaged Heating & Air

This is one of the best solutions for small homes that don’t have the space for large units. A packaged system has a compressor, condenser, and evaporator all in one, making it one packed little system!

These can be stored in an attic or somewhere on your top floor. It is worth noting that their heating system is not as powerful as their cooling system, making it a great option for us Californians, but not for our friends in the north.

Split Systems

One of the most popular systems is a split heating and cooling system. These contain an indoor and outdoor unit for both heating and cooling and are great for homes with a lot of space for them.

The furnace, typically located in the basement, runs on gas and uses a fan to blow hot air over the evaporator coil. These systems are often bundled with an air purifier and humidifier for added home comfort.

Ductless Mini-Split

These systems are a great option for those without a duct system, or those looking to have more control over heating and cooling different zones in their homes. Mini splits are installed in each room, connected to an outdoor compressor. They come with a steep up-front cost, but are an incredibly efficient system.

Mini-splits are a great option for garages and new home additions.
