The Window Unit Struggle Is Real

The annual struggle of installing a window AC is a pain. This guide explores the common frustrations associated with window units and introduces an efficient and comfortable alternative for your home.

We’ve all been there: the first sweltering day of summer hits, and you remember the annual ritual of wrestling a heavy, clunky window air conditioner into place. It's an awkward dance of lifting, shoving, and hoping you don't drop it. And for those of you who leave them year-round, you know the frustration of looking out a window that's half-blocked, limiting your view and the natural light streaming into your home.

The U.S. Energy Information Administration's 2020 survey found that while nearly 90% of U.S. households use air conditioning, only two-thirds of those homes have a central AC system, leaving a segment that relies on individual units like windows, walls, or portable ACs.¹ This is especially true in the Northeast, where over 60% of households primarily use individual AC units.¹

Beyond the seasonal struggle, many window units may come with a unique set of frustrations. A constant, rattling drone can make it hard to hear the television, have a conversation, or get a good night's sleep.

And what about the energy bill? Operating low-energy-efficiency window units may contribute to high energy usage, as such units with low energy-efficiency ratings have to work hard to cool a warm space.

Indoor Comfort Relief From the Struggle

Thankfully, there's an alternative way to stay comfortable. While window units can be effective for cooling individual rooms, they are not the only option. A new generation of air conditioning systems, known as ductless mini-splits, has been gaining popularity for their efficiency and flexibility.

Ductless mini-splits are designed to cool a room, but they can also provide heat during colder months. Unlike window units, ductless mini-split systems are permanently installed, so there’s no need for the annual installation and removal ritual. A compact, wall-mounted design doesn’t block your view or take up valuable space.

Window Air Conditioners vs. Ductless Systems: Understanding the Differences

Feature	Ductless Mini-Split	Window AC Unit
Installation	Permanently mounted	Installed seasonally
Components	Indoor unit(s) + outdoor compressor	Single window-based unit
Energy Efficiency	Eliminates energy loss associated with window installation variables	Poor installation and air leakage may decrease efficiency
Aesthetics	Sleek, modern appearance	Obstructs natural light and view
Noise	Select models are designed for quiet operation	Varies

Ductless Systems beyond the Window

Ductless systems can be an especially good fit in many areas of your home without the need for a window unit or where central HVAC isn’t available or practical. Mini-splits are a good option for:

• Home additions or converted garages
• Finished basements or attics
• Detached spaces like guest houses or workshops
• Rooms with poor airflow or inconsistent temperatures
• Apartments or condos where window access is limited

How Ductless Systems Can Help Reduce Energy Use

While ductless systems may have a higher upfront cost than most window AC units, they are designed with energy efficiency in mind. ENERGY STAR® notes that mini-splits may use up to 60% less energy for heating compared with electric radiators.²

Homeowners should consult with their HVAC professional to learn about available federal and local incentives. Through 2025, qualifying ENERGY STAR^® mini-split heat pump systems are eligible for the section 25C federal tax credit of up to $2,000.*
