Mini-Split Vs. Central: Which Air Conditioner is Right For You?

November 13, 2018 | Blog


Different buildings require different types of HVAC equipment. If you’re considering replacing your current AC and heating setups with brand new system, you’re probably wondering which option is the best for you.

Replacing an air conditioner unit isn’t exactly how it used to be. The traditional central air conditioning units are still available for purchase, but you’ll also have the option to use a mini-split system.

Not too familiar with this type of cooling unit? A ductless mini split air conditioning system is similar to the traditional central unit in the sense that it uses a condenser that sits outside of the house and an air handler that is used inside. What makes it different is that it doesn’t use ductwork to emit its hot and cold airing.

Having a small, easy to install air conditioning system is a huge benefit to some homeowners, which is why mini-split units are growing in popularity. However, there are still some instances in which it might make more sense to choose the traditional central HVAC system.

Here are some factors you’ll need to look out for when you’re considering your next air conditioning system. In this blog, Mission AC & Plumbing puts our air conditioning service Houston TX expertise to use by helping you understand which air conditioning system is best for your home.


When picking the type of air conditioning system you’ll use, this is one of the biggest factors to keep in mind.

Many homes in Texas already have ductwork installed. If this is the situation you’re in, the most cost-effective solution would be a traditional central air conditioning unit. Many newer homes already have ducts intact, so if you’re purchasing a modern residence, it may be best to use a traditional HVAC appliance. This will allow you to maximize what you currently have instead of working around it or paying a hefty fee to get rid of it.

However, the older the residence is, the less likely it is that ductwork will already be installed. If you’re considering purchasing a home that doesn’t currently have any ducts in place, a mini-split ductless air conditioner is a great choice for you. While they still require the attention of a professional HVAC technician, these systems are smaller and easier to set up than central air conditioning units. Instead of worrying about the installation of ductwork followed by a new central cooling system, you’ll be able to bypass this problem. All you have to do is pick the mini-split that works best for you, and then decide where you’d like it mounted.

Living in a home that doesn’t have pre-existing ductwork makes a mini-split system a great option. This system will also make it easier for you to maintain your indoor air quality. Because there aren’t any ducts that need to be inspected, cleaned, and maintained, this means you won’t have to worry about a buildup of dust and contaminants circulating around your house.


Depending on the layout and decor of your home, you may not want to have any sort of HVAC material in plain sight. If you’re trying to make your air conditioner as inconspicuous as possible, then a central air conditioner is right up your alley.

Mini-split ductless air conditioners will need to be mounted on a wall in your home. While there are some very creative ways to style them into your existing interior, the unit will still be in sight.

Investing in a multi-zone mini-split system? If you have a large home, you may need to invest in multiple mini-split units. Generally, if your home is over 2,000 square feet, it will take more than one of these appliances to properly cool and heat the rooms in your residence.

Central air conditioning systems rely on outdoor compressors and condensers, and the parts of the system that are indoors are out of sight. Installing this type of HVAC unit means you won’t have to worry about this appliance getting in the way of your interior decor.

Zone Cooling

Central air conditioning units are circulating cool and hot air all through your house. Because of this, your energy bills may end up being a little more expensive than you’d like. Some people see this added exertion as a waste if they’re living in a home that contains multiple rooms they don’t spend any time in. Do you live in a larger house that has guest rooms and bathrooms, but the living room and kitchen are the only spaces ever used? If you want to experience zoning cooling and filter your air to specific areas of your residence, a ductless cooling system is exactly what you’re looking for.

This is one of the best benefits of the ductless air conditioning system. Depending on the size of your house and its number of residents, you may have rooms in your house that you don’t need to cool. Ductless AC units have the ability to utilize and harness zoning cooling, a method of pinpointing the areas of your home you want to heat or cool. In many instances, we only want to focus on the rooms we use the most, such as our bedrooms and bathrooms.


If you’re only looking at the initial installation, mini-split systems appear to be more expensive than central air conditioning units. However, long-term, a mini-split unit can actually save you money; this type of air conditioner will consistently provide you with lower energy bills than a central system.

The best ductless units are incredibly energy efficient, and they easily surpass their central counterparts. The top mini-split air conditioners generally max out at 27 SEER, while central systems are capped at 21 SEER.


In most cases, a ductless cooling system will be easier to maintain. This is because you won’t have to worry about duct leaks occurring and paying for expensive air conditioning parts and supplies. Newer central air conditioning systems are more durable and easier to fix when issues occur, but they still don’t compare to the longevity and simplicity of mini-split systems.
