How To Choose The Best AC for Las Vegas

Choosing an air conditioner for Las Vegas isn’t the same as buying one for a mild climate. You need a unit that can sustain long hours of heavy cooling without breaking down, freezing up, or running up your electricity bill. Here’s what really matters.

Watch the Real Cooling Number

Manufacturers often list a high BTU (British Thermal Unit, a measure of cooling power) number like 12,000 or 14,000, but the more honest figure is often the SACC (Seasonally Adjusted Cooling Capacity). This is the number that reflects real-world performance, so pay attention to both numbers to understand a unit’s true cooling ability.

Dual Hose Beats Single Hose for Big Spaces

Portable ACs come with either one or two hoses. A single-hose unit pulls air from your room to cool the condenser, which can create a slight vacuum—but a dual-hose system uses one hose to bring in outside air and another to exhaust it, so it cools large areas more efficiently without straining. If you’re cooling a big open living area, a dual-hose portable is the smarter choice.

In‑Depth Reviews

★ Best Overall

1. ZAFRO Portable Air Conditioner

Our pick — 4.5★ from 90+ verified ratings; the strongest balance of quality and price.

Drainage-FreeSmart Controls

The portable that cools your room without ever making you empty a water bucket.

This ZAFRO model is our Best Overall because it solves the biggest annoyance of portable ACs: the water tank. Its self-evaporating system uses a water wheel to disperse moisture onto the condenser, meaning it runs drainage-free—so you aren’t waking up at 2 a.m. to dump a full tray. It delivers 12,000 BTU of cooling power (with an 8,000 BTU SACC rating, the more honest real-world number) in a unit that measures 12.99″ x 14.80″ x 23.23″ and weighs 59.3 lb, with casters and side handles so you can roll it between rooms without lifting.

Buyers report it works effectively in small and medium spaces like a 12×12 room, and that it cools quickly. The noise level drops to just 47 dB in sleep mode, which is about as loud as a quiet library, so it won’t disrupt your sleep. You can set a 24-hour timer to schedule cooling, and it works with the ZAFRO app, Amazon Alexa, or Google Home for hands-free control. The included 22.97 ft remote means you can adjust settings from across the room.

If you’ve struggled with a single-hose unit that kept turning off to “prevent freezing,” this model is a solid upgrade—owners mention it runs constantly without issues. It’s a little large, but the zero-maintenance drainage and reliable performance make it the most complete package for most Las Vegas homes. The compressor is a rotary scroll type (a durable compressor design), and it uses a touch control panel alongside the remote.

Why it wins

  • 72H drainage-free operation means no manual water emptying in normal conditions
  • Multi-mode operation, including cooling, dehumidification, and fan functions
  • Smart controls via app, Alexa, or Google Home

What to keep in mind

  • It’s a heavy unit at 59.3 lb, though casters help with moving
  • Single-hose design may not cool the largest open floor plans as efficiently

Your pick if: you want a portable that runs for weeks without draining and can be controlled from your phone.

Think twice if: you have a massive, open-concept living area that needs the raw power of a dual-hose unit.

Best Value

2. Feelfunn 12,000 BTU Portable Air Conditioner

Cools 600 Sq FtTurbo Mode

The crowd-pleasing portable that cools a big living space without a big-brand price tag.

When you want to cool an entire 600 sq ft room without spending a fortune, this Feelfunn is the strongest value pick. It’s rated at 12,000 BTU ASHRAE (with an 8,050 BTU SACC rating), and its Turbo mode pushes out a fast 64°F blast of cold air at high fan speed to knock out hot spots quickly. Buyers are genuinely surprised by its power, with some noting it cools a large area better than they expected from an off-brand unit. As owners put it: “I have it on every single day for the last two months and it’s still going strong.”

Beyond raw cooling, this unit moves air well with an auto swing louver and 420 m³/h airflow (a measure of how much air it pushes per hour), so every corner of the room gets cold, not just the spot in front of it. If you’re sensitive to noise, the Sleep mode drops it to a whisper-quiet 42 dB with a dimmed display. This makes it noticeably quieter than the ZAFRO model above, which runs at 47 dB in its sleep mode—a real difference if you’re a light sleeper.

It also functions as a dehumidifier, It removes up to 80 pints of moisture per day., which helps in muggy conditions. The 24-hour timer and Smart mode—which auto-switches between cool and fan based on a 73°F threshold—help keep your electricity bill lower. With a CEER of 7.8 (the efficiency rating), it’s a decent balance of power and cost to run. The unit weighs 58.9 lb but rolls easily on four 360° casters, and its window kit fits 20-50 inch windows for a quick install.

The strongest points

  • Turbo mode delivers fast, powerful 64°F cooling
  • Quiet 42 dB sleep mode for undisturbed rest
  • Auto swing louvers circulate air to every corner

A fair caveat

  • Some users find the cooling performance inconsistent in very large spaces
  • The window spacer may not fit perfectly in older window frames

Reach for this if: you want maximum cooling coverage per dollar spent on a portable unit.

Look elsewhere if: you have older, non-standard windows that may need a custom fitting kit.

Best for Apartments

3. EnerGlow 12,000 BTU Portable Air Conditioner

4-in-1 ModesTouch Panel

A versatile companion for renters who need cooling, dehumidifying, and fan modes in one easy-rolling unit.

If you live in an apartment that bans window units, the EnerGlow is built for your situation—customers note it cools multiple bedrooms effectively and even has a discreet window vent that looks like a fan. It’s a 4-in-1 unit that handles cooling, fan, dry, and sleep modes, so it earns its place year-round, not just in the summer. Its 12,000 BTU (8,050 BTU SACC) output and Turbo mode drop the temperature to a brisk 64°F, and the cooling range adjusts from 64°F up to 90°F to match your comfort.

The remote control has a range of up to 23 feet, letting you adjust the fan speed or mode from the sofa. It’s a heavy machine at 58.9 lb, but four 360° smooth-rolling wheels and a built-in ergonomic handle make it easy to relocate, which owners appreciate when storing it in a closet for the winter. The sleep mode runs at a quiet 42 dB and the Smart mode automatically switches between cooling and fan based on the room temperature above or below 73°F to save energy.

Compared to the Feelfunn above, the EnerGlow is nearly identical in core specs like BTU, airflow of 420 m³/h, and a CEER of 7.8—but it differentiates itself with a slightly more sturdy set of controls, including an intuitive touch panel alongside the remote. One buyer’s experience highlights a potential fit issue: the window kit may require cutting to fit narrower windows. It’s a strong choice for renters who need a flexible, multi-season machine that doesn’t require permanent installation.

The versatility win

  • 4-in-1 functionality covers cooling, fan, dry, and sleep modes
  • Remote control range up to 23 feet
  • Touch panel plus remote for easy operation

Watch out for

  • The window installation kit may not fit very narrow or non-standard windows
  • At 58.9 lb, it’s heavy to carry up stairs despite the wheels

Best suited for: apartment dwellers who want a discreet, multi-function unit that rolls away when not in use.

Not ideal if: you have unusually narrow windows that need a custom vent kit.

Top Performer

4. Midea 12,000 BTU Portable Air Conditioner

SmartHome AppAlexa & Google

A trusted name delivering fast, smart cooling for medium-size rooms without the struggle.

When you want the confidence of a well-known brand, this Midea portable is a dependable choice. It delivers 12,000 BTU ASHRAE of cooling (with an 8,000 BTU DOE/SACC rating) for spaces up to 350 sq ft. What stands out here is the cooling speed—reviewers point out It can chill a room in under 10 minutes., with one owner noting it One owner cooled a room from 83°F to 72°F in 15 minutes.. If you’re coming home to a sweltering Las Vegas apartment, that fast cooldown makes a big difference.

The smart features are where this model shines compared to the EnerGlow. You can control it from anywhere using the SmartHome app on iOS or Android, or pair it with your Amazon Alexa or Google Assistant for voice control—so you can start cooling before you even walk in the door. It also functions as a fan and dehumidifier, and owners find the rotary scroll compressor runs quietly, making it less intrusive than some pricier competitors.

One honest note from a buyer who knows ACs well: it cools well, but don’t expect it to handle the absolute maximum square footage it advertises. It’s best for closed-off rooms like a living room, dining room, or bedroom—which is exactly how most Las Vegans use it. The unit runs on a standard 115V circuit and uses the eco-friendly R32 refrigerant, and its installation is genuinely simple with the included exhaust hose and window kit. Expect an annual energy consumption of about 946 kWh if you run it heavily.

A fast and smart pick: This Midea is the one to grab if app and voice controls matter more to you than raw square footage. Buyers consistently highlight how quickly it pulls a room’s temperature down.

The honest limit: It’s best for a single well-sealed room rather than a wide-open floor plan. For that, you’d want a 14,000 BTU model like the ZAFRO below.

Choose it if: you prioritize brand trust and want to pre-cool your bedroom from your phone via the app.

skip it if: you’re trying to cool an open-concept 600 sq ft area—it will struggle compared to larger units.

Best for Large Rooms

5. DELLA 12,000 BTU Smart Window Air Conditioner

550 Sq Ft56 dB Quiet

A smart window unit with high efficiency that’s ready to battle the heat in your largest living space.

For a permanent, whole-room solution, window units often beat portables on efficiency—and this DELLA is a standout in that category. It’s designed to cool rooms up to 550 sq ft, making it a strong fit for a large living room or a combined living/dining area. Crucially for Las Vegas, where ACs run for months, this unit has a Combined Energy Efficiency Rate (CEER) of 10.9. That’s a high-efficiency number meaning it converts more electricity into cooling, which helps keep your monthly bill from skyrocketing during the brutal summer months.

This window unit also integrates with your smart home. It’s Wi-Fi enabled and works with Amazon Alexa and the Della+ app, so you can adjust the temperature or check the mode from your phone. It includes a remote and a clear LED panel, along with 3 fan speeds, Auto/Cool/Fan/Dry modes, a 24-hour timer, and a sleep mode. The temperature setting range spans 61°F to 88°F, giving you plenty of control to find your ideal comfort level.

Compared to the Midea portable above, this is less about portability and more about locking in efficient, whole-home cooling. It fits windows from 26 to 36 inches wide with a minimum height of 16 inches, and at 63.7 lb, it requires a bit more muscle to install—it’s not a unit you’ll move around. Buyers in hot, humid climates like Florida note it’s a lifesaver for reducing reliance on central AC. With an inverter compressor (which runs more efficiently at partial load) and a noise level as low as 56 dB, it’s a solid, quiet workhorse for serious cooling.

Why it’s a strong contender

  • High CEER of 10.9 means more efficient cooling and lower energy bills
  • Cools a large 550 sq ft area effectively
  • Inverter compressor and smart app control for convenience

What to note

  • At 63.7 lb, it’s heavy and needs a second person to install safely
  • Some buyers find the lowest fan speed still too loud for their taste

The pick if: you want a permanent, energy-saving window unit to cool a big room all summer long.

Consider another if: you need something you can move between rooms or your window doesn’t meet the size requirements.

High Efficiency

6. ZAFRO Smart Inverter Portable Air Conditioner 14,000 BTU

Dual HoseCEER 12.8

A high-efficiency dual-hose portable that cools a 700 sq ft space for less than you’d expect.

This ZAFRO takes a big step up in both power and efficiency. It’s rated at 14,000 BTU (with a 10,000 BTU SACC rating) and is designed to cool areas up to 700 sq ft. The key upgrade here is its dual-hose system and inverter compressor. A dual-hose system is much better at cooling a large, open space efficiently, and the inverter compressor varies its speed to maintain a steady temperature without constantly switching on and off, saving energy. This unit achieves a CEER of 12.8—a very high efficiency rating that keeps energy consumption low even during all-day operation.

In the Las Vegas heat, this extra efficiency translates to a lower electric bill. The unit moves a high airflow of 480 cubic meters per hour and features an Extra Mode that locks the temperature at a frosty 61°F and runs at full power for instant relief during a heatwave. Shoppers say it cools large basements and offices easily, and that the dehumidify mode alone can chill a space. The smart inverter technology also means fewer vibrations, so it runs quietly at as low as 42 dB.

Like its smaller ZAFRO sibling, this model is drainage-free for up to 72 hours in environments with less than 90% humidity—which suits dry desert climates perfectly. It comes with a smart app and remote control, a 24-hour timer, and six versatile modes (Cool, Dry, Fan, Sleep, Extra, and Eco). Buyers who’ve compared it to premium rivals say it rivals their performance while being quieter and more energy-efficient. If you want the power of a large unit without the huge price tag of the 16,000 BTU model below, this is a balance.

The efficiency edge

  • High CEER of 12.8 for significant energy savings
  • Dual-hose inverter system cools large 700 sq ft areas efficiently
  • Fast Extra Mode locks at 61°F for instant relief

Before you buy

  • It’s a premium-priced portable, though justified by the specs
  • You’ll need to manage two exhaust hoses in your window setup

Worth it for: homeowners who want big-space cooling and are willing to pay a bit more upfront to save on monthly energy.

Pass if: a single room under 350 sq ft is all you need—a cheaper 12,000 BTU model would do the job.

Smart Value

7. Frigidaire 12,000 BTU Smart Inverter Window AC

Frigidaire App550 Sq Ft

A recognized name in window ACs that pairs powerful cooling with stellar energy efficiency.

This Frigidaire is proof that a big brand can still offer incredible value. It’s a 12,000 BTU window air conditioner that cools rooms up to 550 sq ft, ideal for bedrooms, garages, or home offices. Its standout feature is its energy efficiency—with an It consumes just 485 kWh annually., it’s far lighter on your electric bill than many competitors with the same cooling power. For reference, that’s less than half the yearly consumption of the Midea portable we covered earlier, which uses about 946 kWh. This makes it a fantastic choice for Las Vegans who run their AC for months straight.

Despite its efficiency, it doesn’t skimp on features. The inverter compressor runs quietly and maintains a steady temperature, with buyers noting It can hold a room below 68°F even when outdoor temps hit 100°F.. It offers 6-way multidirectional airflow to circulate air throughout the room, with 3 speeds to choose from. It’s also fully smart-home compatible, connecting to Amazon Alexa or Google Home, and can be controlled from anywhere via the Frigidaire app.

It includes a programmable 24-hour timer and sleep mode to tune temperature overnight, plus a filter light reminder so you know when to clean the pre-filter. One honest note from owners: it’s a large and heavy unit that needs a helper to install, and while it’s generally quiet, it’s not whisper-silent. The quality is consistently praised, with one buyer reporting it outperformed a 14,000 BTU portable in their shed. For a permanent, cost-effective cooling solution, this Frigidaire is tough to beat.

Why it stands out

  • Low annual energy consumption of 485 kWh is exceptional for a 12,000 BTU unit
  • Inverter compressor provides consistent, quiet cooling
  • 6-way airflow direction spreads cool air effectively

Keep in mind

  • It’s big and heavy; you’ll need a second person for installation
  • Wi-Fi setup has been finicky for a few owners

The smart choice if: energy efficiency is your top priority for a fixed window installation.

pass on it if: you need something portable that you can roll from room to room.

Ultra Quiet

8. Midea 12,000 BTU U Shaped Smart Inverter Window AC

32 dBAOpen Window

A revolutionary U-shaped window unit that’s remarkably quiet thanks to its outside-mounted compressor.

If noise is your number one concern, this Midea U is the clear winner. Its unique U-shape design allows the window to close down on the unit, which physically blocks the noisy compressor and vibrations from entering your room. The result is operation as low as 32 dBA—which owners describe as sounding like a table fan on low—making it one of the quietest window ACs you can buy. This is a huge advantage for light sleepers or anyone using it in a bedroom or nursery.

Don’t let the quiet operation fool you; it still delivers serious cooling power. This 12,000 BTU unit cools up to 550 sq ft and is a top-performer in cooling performance, particularly in large rooms with tall ceilings. Buyers report it maintains a cool 68°F overnight without struggle. It also achieves It delivers over 35% energy savings versus traditional units. thanks to its advanced DC Inverter technology, and It was the first window AC to earn ENERGY STAR certification.. It even has a flexible window-opening design, so you can let in fresh air while it runs, and the Anti-Theft Mechanism locks your window for security.

The smart features are excellent: it’s Wi-Fi enabled and works with the SmartHome app on iOS and Android, plus you can control it via voice with Amazon Alexa or Google Assistant. Installation uses a quick-snap bracket and fits single-hung or double-hung windows from 22″ to 36″ wide. Owners are unanimous that it’s a worthwhile install despite being slightly complex. Compared to the Frigidaire above, this Midea trades a bit of energy efficiency for dramatically quieter operation—33 dBA vs. an unspecified but noticeable hum. It’s the premium pick for those who value silence above all.

The quiet advantage

  • Ultra-low noise down to 32 dBA for whisper-quiet sleep
  • Over 35% energy savings with DC Inverter technology
  • U-shape design allows window to open for fresh air

Trade-offs to consider

  • Installing the U-shaped bracket system is more complex than a standard window unit
  • Some owners mention occasional rattling from the front panel after extended use

Pick this for: a bedroom or quiet office where every decibel matters and you want fresh-air flexibility.

Steer toward another if: you want the simplest possible installation or your window is non-standard in size.

Sleek & Smart

9. DREO 515S Portable Air Conditioner

Patented Noise IsolationVoice Control

A smart, quiet portable that brings premium design and voice control to your bedroom cooling.

The DREO 515S is for buyers who want a polished, gadget-forward portable AC. It’s rated at 12,000 BTU ASHRAE (8,000 BTU SACC) and features DREO’s patented Noise Isolation System, which brings the noise down to just 45 dB for a peaceful night’s sleep. The real highlight here is the smart ecosystem: you can control it with your voice via Siri, Amazon Alexa, or Google Home, and the DREO app lets you monitor temperature and humidity, plus customize a sleep curve function that adjusts cooling throughout the night.

It also incorporates DREO’s True Drainage-Free System, which uses a patented algorithm, sensors, and a pump to evaporate excess water automatically—no manual draining needed in environments under 90% humidity, which covers the typical dry Las Vegas climate. The IceCool system increases coverage up to 16 feet away, so you get a targeted blast of cold air even from across the room. Buyers in heatwave conditions report it kept their bedroom cold for days straight, and they appreciate that the front display can be turned off for a completely dark room.

The unit runs on a standard rotary scroll compressor and achieves a solid 6.1 SEER efficiency rating. Weighing about 64.8 lb, it’s one of the heavier portables, so moving it upstairs is a workout even with wheels. One recurring buyer note is that the exhaust hose gets hot during operation—which is normal for portable ACs—and some found the actual noise level measured higher than the advertised 45 dB in their tests. Still, for a well-built, app-driven portable that’s genuinely quiet, the DREO is a top-tier choice that pairs beautifully with a smart home setup.

What makes it special

  • Patented Noise Isolation System for quiet 45 dB operation
  • Voice control via Siri, Alexa, and Google Home
  • True Drainage-Free system with smart pump technology

The honest drawbacks

  • Heavier than most at 64.8 lb, challenging to move up stairs
  • The premium price doesn’t include a larger cooling area than cheaper rivals

Grab this if: you want a sleek, app-connected portable that’s genuinely quiet for a bedroom or nursery.

Think twice if: you need to cool a huge open space or you’re on a tight budget—simpler units offer more square footage per dollar.

Powerful 14K

10. Air Future 14,000 BTU Smart Portable AC

R32 Refrigerant750 Sq Ft

A heavy-duty portable that throws serious cooling power at large spaces up to 750 sq ft.

When you need maximum portable cooling muscle, the Air Future 14,000 BTU delivers. It’s rated at 14,000 BTU ASHRAE (with a 10,000 BTU SACC rating) and can handle areas up to a massive 750 sq ft. This makes it among the most powerful portable units on our list, capable of cooling a large studio apartment or a wide-open living space. It operates stably between 61°F and 90°F and uses the newer, more environmentally friendly R32 refrigerant, which has almost zero ozone depletion potential—a smart choice for the eco-conscious buyer.

This model leans into user comfort with a Quiet Sleep Mode that operates at just 45 dB. The advanced acoustic insulation and vibration-dampening technology keep things peaceful, while the auto swing louver distributes airflow evenly to avoid hot spots. Customers note it’s a lifesaver during heatwaves, It maintains 70°F by day and 67°F at night.. It has a 24-hour programmable timer, a child lock for safety, and control via a responsive touch panel or included remote.

The smart self-evaporation technology reduces condensate buildup, though you should note the unit includes a 1-gallon capacity tank and a mesh filter type. In very humid conditions, some owners have needed to attach a hose to handle the 2-3 gallons of water it can pull from the air daily. The build quality is solid, with heavy-duty 360° swivel casters and recessed side handles for easy movement. For a hotspot in a large apartment, this is the unit to beat—just be aware its real-world performance is best in single rooms rather than trying to cool an entire multi-room floor.

Where it impresses

  • Massive 750 sq ft cooling coverage for large spaces
  • Uses eco-friendly R32 refrigerant
  • Heavy-duty swivel casters for easy room-to-room movement

Consider these points

  • In humid conditions, you may need to connect a drain hose to handle water buildup
  • Some buyers find it runs loudly on the high fan setting

Reach for it if: you have one very large room or studio and refuse to compromise on cooling power.

Look elsewhere if: you need quiet operation above all or your space is small enough for a cheaper 12,000 BTU model.

Understanding the Specs

BTU vs. SACC: The Two Cooling Numbers

BTU (British Thermal Unit) is the raw measure of cooling power—the higher the number, the more heat it can remove per hour. SACC (Seasonally Adjusted Cooling Capacity) is the more honest, real-world number that accounts for how the unit actually performs across different conditions. When a spec lists “12,000 BTU (8,000 BTU SACC),” the second number is what you should use to judge whether it will cool your room.

CEER: Your Electric Bill’s Best Friend

CEER (Combined Energy Efficiency Ratio) measures how efficiently a unit converts electricity into cooling power. A higher CEER number—like the 12.8 seen on some ZAFRO models, or the 10.9 on the DELLA—means the unit delivers more cooling per watt of electricity used. In Las Vegas, where your AC might run for months, choosing a unit with a high CEER will save you real money over the summer.

FAQ

How many BTU do I need for a Las Vegas apartment?
For a standard Las Vegas apartment bedroom or living room up to about 350 sq ft, a 12,000 BTU unit is the balance. For larger open-concept areas between 500 and 800 sq ft, you’ll want to step up to a 14,000 BTU or 16,000 BTU model to avoid the unit running constantly.
Which cools better in extreme heat: a window unit or a portable?
Window units are generally more efficient because they don’t have to pull air from the room to cool the condenser. Units like the Midea U or Frigidaire window models are excellent choices. However, dual-hose portable units like the ZAFRO 16,000 BTU have narrowed the gap significantly and offer the flexibility of being moved between rooms.
What does the SACC rating mean for a portable AC?
SACC stands for Seasonally Adjusted Cooling Capacity. It’s a more realistic measure of a portable AC’s cooling power than the raw BTU number because it accounts for real-world conditions. When a spec says “12,000 BTU (8,000 BTU SACC),” the SACC number is the one you should use to judge true performance.
Is a dual-hose portable AC better than a single-hose?
For large spaces, yes. A dual-hose system uses one hose to draw in outside air and another to exhaust hot air, which prevents it from pulling cooled indoor air out of the room. This makes dual-hose units much more efficient at cooling open areas. Single-hose units are simpler and cheaper but best for smaller, closed-off rooms.
Will a portable AC need frequent water draining?
It depends on the model and your humidity levels. Many modern units, like the ZAFRO and DREO models, feature self-evaporating technology. This means they recycle the moisture to cool the condenser coils and evaporate it through the exhaust, so you rarely need to empty a tank in dry climates like Las Vegas, where humidity is often below 90%.
Can I run a window AC with my smart home setup?
Yes, many of the top picks are smart-enabled. Units from Midea, Frigidaire, and DELLA are Wi-Fi connected and work with Amazon Alexa and Google Home voice commands. This lets you start cooling your room before you even arrive home, so you never have to walk into a hot house.
How noisy should I expect portable AC units to be?
This is where you’ll see a real range. The quietest units operate around 32-42 dB, which is about as loud as a quiet library. Units like the Midea U, ZAFRO, and Feelfunn excel here with sleep modes. Others, particularly cheaper or more powerful models at high fan speed, can get noticeably louder. Always check the dB rating if noise is a concern.
What is the best way to install a portable AC in a slider window?
Most portable ACs come with a window kit designed to fit both double-hung and sliding windows. The kit includes adjustable panels that you extend to match your window width. For older or non-standard windows, you may need to use an additional foam seal or a custom-fit kit to ensure a proper seal and prevent hot air from leaking back in.
Are inverter or non-inverter ACs better for the summer heat?
Inverter ACs are better for sustained, all-day use in extreme heat. A non-inverter compressor switches fully on and off to maintain temperature, which uses more energy and causes temperature swings. An inverter compressor like the one in the ZAFRO and Midea units runs at variable speeds, so it maintains a steadier temperature and uses less electricity over time.
