Advantages of Ductless Mini Split Heat Pumps
Mini split systems are ideal choices for homes with no existing ductwork, as well as for ADUs or additions. They’re also one of the most efficient HVAC systems on the market due to their inverter technology, which allows them to generate only the amount of cooling that’s actually necessary.
Here are a few additional benefits of a ductless system to consider:
Room-by-room temperature control: Since each unit in a ductless mini split system has its own remote, you can adjust the temperature settings for each zone separately.
Energy efficiency: Ductless heat pumps control the temperature and humidity in your home using only the necessary amount of energy.
Quick installation: Mini split systems can be installed without major structural disruption to your home, via a small hole in the wall to connect each indoor unit to your outdoor compressor.
Lower energy bills: While the upfront cost of installing a ductless heat pump system is typically higher than that of central air, the efficiency of a ductless system will reduce your utility bills substantially; in this way, a ductless mini split heat pump is a great long-term financial investment.
Disadvantages of Mini Splits
The primary drawback of a mini split system is the upfront cost. On average, the initial cost of installing a ductless heat pump system is about 30% higher than the cost to install a central system (without ductwork). The efficiency of this kind of setup reduces your utility costs substantially, making it a fantastic long-term investment if you’re planning to stay in your current home for the next few years. However, if you’re planning to move in the near future, your return on investment is reduced.
The other factor to consider is space. While a mini split’s outdoor compressor is generally smaller than a traditional central AC system, the indoor units are visible in your home (unless you opt for a ducted mini split system). Central air is generally more inconspicuous.
Advantages of a Central Air Conditioning System
There’s a lot to love about central air. Central AC remains the most common type of home cooling system in Canada, and is an optimal choice for individuals and families who live in larger homes and need a consistent temperature throughout.
Some of the major benefits of a central air conditioning system include the following:
Convenience: With central AC, you can control the temperature of your entire home using a single thermostat and rely on a consistent and reliable temperature.
Lower upfront costs: While running a ductless mini split system is less expensive long-term, central air is less expensive to install.
Compatible with existing ductwork: Central AC works in conjunction with your home’s existing furnace systems, so there’s no need for new ductwork.
Increased property value: Installing central air in your home can raise your property value by up to 10%, according to real estate experts.
Air filtration: Ducted systems are superior when it comes to filtering allergens, dust, and odors in your home.
Disadvantages of Central Air
If your home doesn’t already have ductwork, installing central air becomes much more complicated. You’ll also need to maintain your ducts over time.
Another thing to think about is cost. While the price of having central AC installed may be lower than a ductless mini split system, central air doesn’t offer the same benefits on your utility bills every month. That said, it does boost your home’s property value.
Which One is Right For You?
There are major advantages to both central AC and ductless AC, as well as some drawbacks. In the HVAC world, it’s often fruitless to talk about “better” or “worse” systems, because the right system for you depends on your home, family, lifestyle, and budget.
In general, the factors to consider when choosing between a ductless mini split system and a central air conditioning system include upfront and monthly energy costs, installation time and complexity, your local climate and temperature conditions, and your lifestyle and preferences:
The cost of installing central air is lower than the upfront cost of a mini split system, especially if your home has existing ductwork. However, a ductless AC system saves you money in the long run due to its innovative and efficient technology.
While both systems require professional installation, a ductless system is very quick to install, while a central air conditioning system involves a more complex process.
When temperatures reach extreme highs or lows, it can interfere with a mini split system’s capacity. Mild climates like that of the Pacific Northwest are ideal for ductless heat pumps, since temperatures rarely drop or rise to extremes. In less mild climates, central air is a safer bet for extreme temperatures (though there are some ductless options that can handle more extreme temperatures).
How you use your home is a major consideration when you’re choosing between two types of AC. Since mini split units are controlled via remote control, you have the option of cooling only one room or “zone” at a time, or setting zones to different temperatures. This is ideal if there are rooms in your home that are rarely used during certain hours of the day. However, if you need your entire home to remain at a consistent temperature throughout the day, a centrally controlled AC system may be more convenient.
