Choosing between window AC vs central AC is tricky. It’s a challenging one for any homeowner or tenant.

With so many variables at play, it can be challenging to determine whether you’re making a good investment or wasting money.

It all comes down to making the best decision for your cooling needs and environment. Therefore, what’s the solution? Do you splash the cash and install a central air conditioning system throughout your house, or will you opt for a few window AC units instead?

In this article, we’ll go through each of these air conditioning units in depth to help you select the best one for your residence and, of course, your budget.

Let’s get straight into the details.

Window AC vs Central AC: Costs

Cost to Buy 

The average cost of central AC unit installation in the US is between $7,900 and $11,900, or around $10,000.

On the contrary, a decent 12,000 BTU window air conditioner typically costs approximately $400. This is between 1/18 and 1/28, the cost of a central air conditioner that covers 500 square feet.

That’s a sobering realization that makes you question whether a central air conditioner is worth the hassle. However, most buyers consider other factors, such as the number of window AC units required.

Some homeowners prefer several window units in a smaller house, up to 1,200 square feet in size. One belongs in the living room while the other belongs in the bedroom.

Cost to Install

The labor cost of installing a central air conditioner ranges from $2,100 to $3,700. The system size, the location of the equipment, the length of the refrigerant lines, the volume of refrigerant, and the overall complexity of the task all contribute to determining this cost.

As for window units, practically all homeowners install their own or have a relative or friend do it for free. Cost: $0! However, you should budget $75 to $200 per unit if you employ a handyman service to install your window air conditioners.

Cost variables include the size and weight of the window air conditioner unit, whether it must be moved upstairs, and whether the contractor thoroughly cleans it before installation. The latter is a smart option if it hasn’t been cleaned recently.

The cost to fix central air conditioner is higher than that of fixing a window AC. 

Total Equipment and Installation Cost

You might be charged up to $1,000 to install 5 window air conditioners. And if you pay an average of $450 for each unit, totaling $2,250, your overall expenditures would be $3,250.

This amount is still less than a third to a quarter of the central air conditioning installation cost, which is approximately $10,000.

If you also need to install ducts, your total central air cost jumps to roughly $15,000, making window air conditioners more appealing from a financial standpoint. (1)

Window AC vs Central AC: Efficiency

Central Air Conditioners: These models offer the convenience of chilling the whole house rather than just one room. As a consequence, they are often more energy-efficient than many other alternatives.

Talking of alternatives, be sure to check out how efficient heat pumps are compared to central ACs.

Instead of having a portable system at the office, a wall edition downstairs, and a mobile unit in the bedroom, you’ll need one efficient unit.

In the long term, this may result in lower energy costs. Also, most central AC systems are quieter and less obtrusive while operating.

Window Air Conditioners: These entities have come a long way in the window AC vs. central air debate. However, modern innovations have propelled many window ACs to be Energy Star Certified, geared to improve energy efficiency.

You may be familiar with certain energy-efficient brands, like those produced by GE, LG, and Frigidaire.

Due to their increased efficiency, they now contribute significantly to the health and enjoyment of everyone throughout the summer.

However, energy efficiency sometimes goes beyond the system itself. It may be influenced by the maintenance and prompt AC repair service you get for your cooling system.

Window AC vs Central AC: Aesthetics

Central Air Conditioners: When operating, these HVAC systems provide a muted, less noticeable sound. Another feature that has many people enthralled? They’re usually concealed and disguised around corners and in backyards.

This will allow you to see all your window panes inside and outside.

However, you may need to get central air conditioner covers for outside units at an extra cost. 

Window Air Conditioners: These units block the glass and prevent people from viewing what’s happening outside. Also, they are easily noticeable to passersby outside the house.

However, even though they’re not aesthetically pleasing, you can dismount them and store them in the basement during winter.

Window AC vs Central AC: Humidity Control

Central air conditioning systems generally remove more moisture from the air than window air conditioners. This improves the air quality.

So, although it may be tempting to get a big window AC to ensure it does the job, resist the urge. It will generate cooled yet humid air, making the space cold and damp.

Window Air Conditioner vs Central Air: Noise Levels

Most central air conditioners have a decibel range of 60 to 77. However, the noise level inside isn’t too bad since the central AC unit is located outside, and your windows are sealed when the AC is on.

Sitting near a window, you’ll hear a faint hum from the exterior unit or a quick “buzz” as it starts up. The air movement through the ducts and grates is not audible.

The noise level of window air conditioners ranges from the low 40s to the mid-60s. However, these units are located in the window, and many of the side panels are not silenced. So, window air conditioners are louder.

If your AC is making weird noises, such as screeching and buzzing, you need to call for emergency AC repair Los Angeles. 

Climate Considerations – Which AC is Best for Where You Live?

One benefit of using several window ACs over central ACs is that you may use them to cool the rooms. One or two window units consume less energy than a whole-house central AC.

The warmer and more humid your home’s climate is, the more sense it makes to pick central air conditioning over window air conditioning. Otherwise, your whole house will be unpleasant for most of the day, particularly in the afternoon and the evening.

Central air systems provide more comfort and convenience in very hot regions.

Frequently Asked Questions

We answer some FAQs on window vs central AC. Consider these questions when deciding between the two.

If your pressing question is not answered, feel free to seek commercial AC & HVAC services. 

Is it cheaper to run a window air conditioner or a central air conditioner?

That depends. If you want to cool your entire property, having many window ACs will consume more energy than a solitary properly-sized central AC. A window AC is an obvious choice if you only want to cool a room.

Will a window unit help my AC?

Are you unsure whether integrating a window air conditioner with your central heating and cooling system would result in cost savings? For instance, if you need to cool one room in your house instead of the entire area, you may be inclined to use a window unit most of the time.

Technically, there is nothing wrong with carrying this out in the right conditions. There may, however, be other options, such as using your thermostat’s circulation function if it has one. Before purchasing a separate air conditioner, review the owner’s manual.

Is central AC more efficient than window AC?

  Central AC is definitely more energy-efficient if you want to cool the entire house (or several rooms). In this situation, having many window ACs will end up being expensive. However, if you want to cool just one room, such as an extension from your house, it is more reasonable to opt for a window AC.

Can a window AC cool the entire house?

 It is challenging for a window AC to cool a larger space. They are designed to cool a single room. The most it can do is two adjacent rooms, which will strain the system. For a system to cool the entire house, go for central AC.

 Final Thoughts

There we go: central air or window units?

At this point, we are confident that you have identified the AC system that best suits your needs.

Be sure to keep your budget in mind while shopping for the two. Remember, the upfront cost can be misleading. This is why it is essential to consider other factors. Consider energy efficiency, your climate, and other maintenance and operation costs.
