Comparing Mini-Splits vs. Other Home Comfort Systems

When shopping for a heating and cooling system for your dwelling, it’s essential to choose one that balances efficiency, functionality and budget. That’s why many families look to mini-splits to heat and cool their home.

Mini-splits—often called ductless mini-splits—have many advantages that make them an appealing choice for both homes and businesses. They're very energy efficient, lowering energy consumption and saving on utility bills, because they avoid the energy losses associated with the ductwork found in traditional HVAC systems. They also allow users to customize the temperature in each room, enhancing overall comfort while not wasting energy.

If you’re contemplating mini-split installation in Huntsville, it’s necessary to first find out if these devices are the best fit for your living situation. Here, we’ll explore how mini-splits measure up to other heating and cooling methods.

What a Mini-Split Is and How It Works

A mini-split, or ductless mini-split, is a heating and cooling system that does not use ductwork. It's often used in homes that don't have any air ducts and for homes with rooms that aren’t served well by the home's existing HVAC system.

A mini-split system has two major components: an outdoor compressor/condenser and an indoor air-handling component. These are connected by a conduit containing the power cable, refrigerant tubing, suction tubing and a condensate drain.

Here's how it works: the outside compressor distributes the refrigerant necessary for heat exchange throughout the coils and the air handler. The interior device draws in air from the room, cools or heats it over the coils and sends the conditioned air back into the room.

Mini-Split vs. Central Air

Mini-splits provide targeted cooling in certain rooms or zones of your residence. They are known for energy efficiency because they only provide hot or cold air for the areas you want. However, they sometimes don't blend seamlessly into every room due to their wall-mounted indoor units.

On the other hand, a central air system uniformly cools your entire home, generating consistent comfort levels throughout. Its ductwork is tucked away in a mechanical room or closet, preserving the interior design of your home. But it might not be as energy efficient as a mini-split, especially in larger homes or residences where certain spaces may not need nonstop conditioning.

Mini-Split vs. Window AC/Window Unit

Mini-splits are typically more energy efficient and not as loud as a window air conditioning unit and are useful for cooling air in multiple rooms. This is why mini-splits are a convenient choice for countless homeowners. They also utilize a type of refrigerant that is more environment-friendly, reducing their environmental impact. These systems can even add value to your home due to their reliable nature and superior cooling capabilities. However, they come with a higher purchase price.

Having said that, window air conditioners are less expensive to purchase. They may be a good fit for homes that can't accommodate a central AC system or for families with budget constraints. Even with these advantages, window units can use up to 40% more energy than ductless mini-split systems and are often noisier.

Mini-Split vs. Portable AC

The answer to what is better, a ductless mini-split or a portable air conditioning unit, depends on your priorities. If your main focus is energy efficiency and cooling capability, a mini-split is heads and shoulders better than a portable AC unit. However, if budget is a key concern, a portable AC costs less.

Mini-Split vs. Gas Furnace

The choice between a mini-split system and a gas furnace depends on a variety of factors such as the climate in your city, home size, energy efficiency preferences and how much you plan on spending.

A mini-split system typically is more energy efficient than a gas furnace. It can heat and cool targeted areas inside of your home, delivering custom climate control in targeted rooms. Mini-splits also are normally quieter and have a larger up-front cost, but their operating costs are usually lower due to their greater energy efficiency.

Alternatively, a gas furnace can be a very effective heating source, particularly in colder climates where mini-split heat pumps may fail to maintain comfort levels in the bitter cold. Even though they are less energy efficient than mini-splits, gas furnaces ordinarily cost less. However, their operating costs can be more costly, especially if natural gas prices jump up.

Mini-Split vs. Heat Pump

Mini-splits and heat pumps function with the process of heat transfer. They are both energy efficient, but a heat pump's ductwork can be less efficient. That said, the choice between a mini-split and a heat pump often is based on on a family's needs and circumstances.

For instance, if you live in a warmer climate and primarily need cooling, a mini-split system might be a more effective choice. However, if you want both heating and cooling and already have ductwork in your home, a heat pump could be a more efficient option.

Mini-Split vs. Space Heater

When it comes to heating and cooling a household, mini-splits and space heaters each have strengths and weaknesses. However, for total efficiency, versatility, comfort and safety, mini-splits come out on top. Mini-splits supply superior energy efficiency simply because they deliver conditioned air straight to different zones and can serve numerous rooms at once.

Space heaters are far less expensive to buy but are typically reserved for heating a limited area or just one room. They also are often less energy efficient. As opposed to mini-splits, space heaters do not supply cooling. The biggest drawback for space heaters is the chance of fire. Experts say some 1,700 fires each year involve space heaters.
