The sunny skies and rising temperatures of summer started on June 21, 2024 in Albuquerque. When you look outside at the shimmering heat, thoughts of refreshing air conditioning bring some relief.
But then you remember last July’s power bill after running your AC nonstop for weeks. The amount was eye-popping. There has to be a better way to stay comfortable this summer without breaking the bank!
Follow along to discover how window units can help you stay cool while keeping your energy bills under control this summer!
Why Choose Window AC Units?
Window air conditioners have evolved lightyears beyond the bulky, screaming metal boxes you might picture. Today’s window AC units are sleek, sophisticated machines designed for energy efficiency and customized cooling. Before we dig into maximizing their potential in your home, let’s look at some of the top reasons window ACs should be part of your summer cooling plan:
Affordable Purchase Price
One major appeal of window AC units is their relatively low purchase price compared to other cooling systems. While a central air system requires an investment of thousands of dollars for the equipment, ductwork, and professional installation, you can purchase a quality window AC unit for a few hundred dollars. And that price includes everything you need to install it yourself right out of the box.
The upfront cost for a window unit sized appropriately for a living room or bedroom is comparable to a nice TV or appliance. For smaller rooms, you can find more basic units for $200 or less. Larger capacity units for bigger spaces can run up to $800. While not dirt cheap, window ACs provide serious value for a moderate initial investment.
And since no ductwork or professional installation is required, you pocket even more cash by opting for a DIY installation. We’ll cover how to install window units properly later on. The simple process is definitely doable for most handy homeowners without any background in HVAC work.
Energy Efficient Operation
After the initial purchase, ongoing energy costs are where window units really pay off. Window air conditioners use far less electricity than central AC systems.
For one, window units are designed for cooling small, confined rooms. So it takes much less power to chill a 150 square foot bedroom than a 2000 square foot house with central air. Their compact nature makes them inherently more energy efficient.
Additionally, today’s window AC models utilize advanced technology like inverter motors and smart sensors to optimize electrical usage. Look for units with a high Energy Efficiency Ratio (EER) of at least 10 or above. EER measures how many BTUs of cooling are produced per watt of electricity used. The higher this number, the greater the efficiency.
For even more assurance of energy savings, seek out units certified with the EPA’s Energy Star label. Energy Star evaluates products based on strict efficiency guidelines. Their certification is solid proof a window AC offers maximum cooling with minimum electricity expenditure.
Finally, window units give you precision control over what areas you cool and when. Turning units off in rooms you aren’t occupying further limits energy usage. Smart supplemental use of window ACs in tandem with central air (more on that later) is a failsafe route to lower power bills.
Compact Size Fits Small Spaces
Window AC units earn their name from their design specifically engineered to fit standard window frames. This compact size is a major advantage for several situations.
For one, small homes and apartments simply don’t have space for large ductwork running throughout. Window units provide powerful localized cooling from a minimal footprint. No bulky vents, grilles, or condensing units eating up floor area.
In homes with central air, window units are ideal for adding cooling to rooms that lack ductwork like converted attics or garages. Their size also makes them perfect for installing in rental units where altering ductwork may be prohibited.
Finally, window ACs can efficiently cool additions, above-garage spaces, or mother-in-law suites that were built without considering ductwork. Their diminutive proportions ensure you can chill these often oddly-shaped areas that central air can’t reach.
Customized, Supplemental Cooling
Here’s where window units really shine – providing personalized cooling right where and when you need it without cranking up the entire central system. This strategic use directly reduces energy consumption.
Some examples:
- Run a window AC in bedrooms at night so you can turn the central air down or off while sleeping. Bedrooms need cooling the most during hot summer nights.
- Use a window unit in home offices or kids’ rooms that require extra cooling during waking hours when the rest of the home doesn’t. Shut it off when not in use.
- Chill workshops, gyms, or hobby rooms only when occupied to avoid cooling vacant spaces 24/7.
- Supplement insufficient central AC cooling in especially hot rooms like kitchens or third floor spaces.
- Keep nurseries at ideal temperatures for napping babies without impacting the rest of the home.
Get the picture? Window units allow you to create custom, zone cooling so you’re not paying to cool empty rooms or over-cooling parts of your home that need it less. Strategic use of window ACs can seriously lower energy bills compared to setting your central thermostat lower to reach desired temps.
Helpful Cost-Saving Features
Beyond superb efficiency, today’s window ACs offer extra features that make it even easier to control costs. Look for models with:
- Programmable timers: Set the AC to start cooling before you get home or turn off when you leave. No need to run for empty rooms!
- Remote controls: Adjust settings from your bed or couch instead of walking to the unit.
- ** Temperature sensors:** Units with onboard sensors automatically adjust cooling output based on the room’s temp.
- Sleep modes: Lower fan speed and noise for undisrupted sleep.
- Multiple fan speeds: Faster for quick cooling, slower to maintain temp. Use as needed.
These convenient features help window ACs better conform to your usage patterns, lifestyle, and cooling needs for energy savings.
Purchasing Considerations
Now that you know the benefits, let’s discuss what to look for in a window AC unit to choose the right model for your needs.
Sizing by BTUs
The first and most important step is to select adequate cooling capacity, measured in BTUs. BTU stands for British Thermal Units. This value represents the amount of energy required to heat or cool one pound of water by one degree Fahrenheit. In other words, higher BTU = more cooling power.
BTU needs are determined by the room’s size, exposure to sun, and a few other factors. An undersized unit won’t provide sufficient cooling. An oversize AC is less energy efficient and costs more upfront.
Luckily, there are easy BTU calculators online where you plug in your room’s measurements for a perfect fit. AC manufacturers also provide sizing charts specific to their products.
As a very rough estimate:
- 100 – 150 SF rooms = 5,000 – 6,000 BTUs
- 150 – 250 SF rooms = 6,000 – 7,000 BTUs
- 250 – 400 SF rooms = 8,000 – 10,000 BTUs
- 400 – 550 SF rooms = 10,000 – 12,000 BTUs
Consult an AC sizing calculator for your exact cooling requirements. Purchase the unit with the closest BTU rating at or above the room’s needs.
AC Unit Types
Windows ACs come in two main configurations:
Single hose: One hose vents hot air outside while cooled air circulates into the room. Effective and most affordable option for smaller rooms.
Dual hose: Dual hoses independently draw hot air out and circulate cooled air in. More powerful and efficient, ideal for larger rooms. Costs a bit more.
Consider splurging on dual hose models for master bedrooms, living rooms, and other main rooms for maximum energy savings. Single hose units work well for smaller spaces like offices.
Added Features
As mentioned before, look for helpful tech features that let you customize and control cooling:
- Programmable timers
- Wi-fi app control
- Remote monitoring
- Temperature sensors
- Multiple fan speeds
- Sleep mode
- Auto-restart after power outage
Even better, seek out a good warranty. Units with 5-year average coverage show a manufacturer who stands behind their quality.

Proper Installation
Installing your window AC correctly ensures it operates efficiently and effectively for years to come. Set your unit up right with these tips:
Location
Find a north or east facing window without direct sun exposure if possible. Avoid southwest windows that get intense afternoon sun. Solar heat makes your AC work harder to remove heat.
If a southern exposure can’t be avoided, install external shade like an awning, blackout shade, or even outdoor landscaping that blocks excessive sun and heat gain.
Window Prep
Inspect the window frame where you’ll install the unit. Look for rot, gaps, level alignment or other issues that require repair before proceeding. The AC frame must seal tightly against the window for optimal efficiency.
Use caulk to seal any window gaps or cracks before installation. This prevents cooled air from escaping through tiny openings. Foam weatherstripping tape also works to seal small leaks.
Proper Angle
The AC unit must tilt slightly to the outside (around 3 degrees) so that condensation can drain properly. Most window units have feet that adjust the angle.
Place a small level on the bottom of the installed unit to check for proper pitch. Adjust the feet height as needed until condensation will run off the sloped bottom outside.
Secure Bracing
Check that the AC unit extends just slightly beyond the exterior wall so that the back is not flush. This allows the front bracket to angle into the room for support.
Use the provided brace or support bracket screwed into the window sill to anchor the base firmly. This prevents tipping from the weight when extended outside the window.
Tight Air Seal
After setting the angle and securing with braces, seal any remaining air gaps with weather stripping and insulation. This stops cooled air from escaping and hot outdoor air from entering.
Focus weather stripping on the interior between the unit’s frame and window, but a little on the outdoor side won’t hurt. Duct tape, caulk and foam sealant also work for stubborn gaps.
Understand Electrical Needs
Most standard outlets provide 15 to 20 amps of power. Smaller units under 10,000 BTU pull within this limit. Verify higher capacity ACs have the right amperage with an electrician if needed.
Try to place the unit within reach of an existing grounded outlet. Only use GFCI outlets near water sources like a sink. Use caution running extension cords – avoid overloading circuits.
Maintenance Is A Must
Like any appliance, window ACs require regular maintenance for optimal performance. Be sure to:
- Check and clean air filters monthly. Clogged filters reduce airflow.
- Vacuum debris that accumulates around outdoor vents. Blocked airflow causes inefficiency.
- Inspect weather stripping and reseal outdoor gaps as needed each season. Prevent leaked cool air!
- Call a technician for an annual tune-up. They can spot and correct issues to save you money.
Additional Perks
Beyond cooling, some window AC units offer extra features that enhance comfort:
- Dehumidifier modes remove excess moisture from muggy indoor air.
- Air purification filters capture allergens and reduce dust.
- Fans-only settings circulate air without cooling for fresh airflow when you just need a breeze.
- Heating capabilities in some models provide cozy warmth during Albuquerque’s chilly winter nights.
Final Thoughts
Staying cool on a budget in Albuquerque is easy with smart window AC usage. Their low cost, energy efficiency, compact size, and versatility make window units a cooling option with outstanding value. Follow these tips to enjoy chilled summer comfort without the shock of sky-high electric bills!
