“Which Air Conditioning System Is Best for My Home?”


With temperatures already warming up, if you’re asking which air conditioner is best for your home now, chances are that you need it pretty urgently. That said, this is definitely a purchase you don’t want to just rush into, as that can leave you with an inefficient or improperly installed cooling system.

If you’ve stumbled across this blog post, it probably means that you already understand this shouldn’t be a rushed decision. In that case, read on to uncover the different types of air conditioners we install and service, and what their different features and benefits are.

Central Air Conditioner

The central air conditioner also called a split-system air conditioner, is the most commonly seen one in homes throughout Tennessee and beyond. They are comprised of a single outdoor unit, hooked up to a single indoor unit that has a series of ducts that distribute cooled air throughout your home.

With all the advancements in HVAC technology, you may wonder if it’s even worth it to stick with this traditional type of air conditioner, or if you should skip right ahead to reading about heat pumps and ductless systems. We can tell you with confidence that the central air conditioner is still a very popular choice for homeowners, with today’s models being exponentially more efficient than those manufactured even just a decade ago.

Heat Pump

A heat pump system works very similarly to a standard central air conditioner. The registers in your home draw out hot air, and it gets expelled outside, while air from outside travels over coils within the system that cools it off and allows it to return chilled air into your home through a series of ductwork and affiliated vents.

The difference between a heat pump and a traditional central AC is that the heat pump can reverse the refrigerant process. This means that not only does it cool, it heats too, and because it transfers heat instead of generating it, it’s even more efficient than, say, a furnace is.

Dual Fuel System

Even though a heat pump system can be more efficient than a furnace, there are those days in the wintertime that get so chilly that the heat pump will struggle to draw in enough warm air from the outside in order to heat your home. A dual fuel system combines the power of a heat pump’s cooling with more efficient heat, from a backup furnace, for those chillier days.

Zone Control System

A zone control system is another layer that can be added to your central air conditioner or heat pump system. We install what’s called dampers in the ductwork of your comfort system so that you can get less cooling (or heating) in the rooms that don’t necessarily need as much.

You might be wondering why you can’t just close off the vents to rooms that don’t need conditioning–well because this throws off the air balance and can cause your air conditioner to work harder to do its job, leading to a potential premature breakdown. A zone control system is specifically designed to avoid this.

Ductless System

Ductless systems combine the benefits of a heat pump (its cooling and heating capabilities) with a zone control system (the ability to heat or cool different rooms at different levels), plus improve indoor air quality by not requiring any ductwork. These systems are highly efficient, and save space! Please don’t hesitate to reach out to our team to learn more.
