During the warmer months, window air conditioning units are the norm for many Massachusetts homeowners. But are they the only solution, or is there a better option?
In the past, Window ACs have been one of the few ways to enjoy air conditioning in rooms that lack ductwork or central AC.
Today, mini-split heat pumps offer homeowners an alternative source of home cooling!
The following comparison of mini-split heat pumps and window air conditioning units discusses the advantages and disadvantages of each system.
Advantages of Mini-Splits
Efficiency: Mini-split heat pumps tend to operate more efficiently than window air conditioning systems. Heat pumps use inverter technology, which allows the compressor to operate at variable speeds. This means mini-split systems can adjust their output based on the cooling needs of the room, using only the necessary amount of energy to maintain the desired temperature.
Dual Heating & Cooling Capabilities: In addition to providing efficient cooling, mini-split heat pumps also offer efficient heating. This dual feature offers homeowners added comfort year-round, solving two comfort needs all in one system.
Quiet Operation: Mini-split systems are known for their quiet operation, especially compared to window air conditioners, which can be noisy and rattle in place. This can be especially useful for bedrooms or other quiet spaces in the home.
Ductless, Room-by-Room Installation: Unlike central air conditioning systems, mini-splits do not require any ductwork to be installed. Homeowners can install mini-splits in individual rooms all at once or break up the installation over several months or years.
Additionally, once the system has been installed it is ready to cool or heat your home whenever you need it.
Aesthetics: Compared to window ac units, mini splits tend to be more aesthetically pleasing and offer more style options to choose from.
Homeowners can choose between white, black and chrome wall-mounted units (pictured) or install floor-mounted or ceiling cassette-styled mini-splits.
Improved Air Quality: Mini-split systems use multi-stage filtration to remove dust, allergens, and other particles from the air, creating a healthier living environment.
Energy Incentives: Mini-split heat pump systems currently qualify for up to $2,000 in federal tax credits through the Inflation Reduction Act. Plus, Massachusetts homeowners may qualify for additional mini-split incentives through programs like Mass Save.
Disadvantages of Mini-Split Heat Pumps:
Upfront Cost: The primary disadvantage of mini-splits in comparison to window ACs is the initial price tag. Mini-split systems tend to have a significantly higher upfront cost than window units.
Keep in mind, however, that mini-splits tend to be a more efficient, year-round comfort solution, as they provide heating AND air conditioning.
Not a “Quick Fix”: We all know the stories of stores running out of window AC units come the first hot day of the season. Mini-splits are not a “quick” fix solution in the way Window AC units can be.
It can take time to find the best contractor and system design for your home, especially during the busy summer season.
That’s why it’s best to plan ahead by working with a contractor in the spring if possible!
Advantages of Window Air Conditioning
Lower Upfront Cost: As a less permanent and efficient cooling option, window air conditioning systems are significantly more affordable to purchase and install than mini-splits. This is because they do not require professional installation and use less advanced technology. They also do not offer dual heating/cooling options.
Portability: Window AC units can be removed and transferred to different locations if needed. For this reason, Window AC units tend to be a better option for renters or those about to move to another location (though it is worth considering what mini splits may add to your home’s value).
Availability: Window AC units are easily bought at most home improvement stores and do not require professional installation.
Disadvantages of Window Air Conditioning
Less Energy Efficient: Window units typically have fixed-speed compressors that are less efficient than mini-split systems. In instances that the window unit does not fit perfectly in the window, free air flow between the room and outdoors can reduce the system’s efficiency.
Inconvenient and Unsafe: Window air conditioners can be inconvenient, and even dangerous, due to their heavy and difficult-to-install nature. In many situations, homeowners find themselves balancing the heavy system on the windowsill while attempting to set up the window air conditioners. Window units may require additional burglar proofing measures as they leave the home vulnerable.
The hassle necessary to set up and take apart the system also makes it difficult to easily access the AC if a warm day comes at the end of the season once the unit is already put away.
Limited Functionality: Unlike mini-splits which provide cooling and heating, Window ACs only provide cooling. This limits their use, especially in locations like Massachusetts, that experience a variety of seasons.
Aesthetics & Noise: Window AC units are often boxy, obstruct natural light and limit window use. In addition to their aesthetic limitations, window units tend to make more noise when they operate, compared to mini-splits.
Mini-splits and window air conditioners each have their own set of advantages and disadvantages. It’s important to prioritize your home’s short-term and long-term comfort needs.
If you’re looking for a long-term, efficient comfort solution, mini-split heat pumps are likely the best choice for your home. Renters or those looking to move within the next year, may be better off with window AC units for now.
