Finding a window or portable unit that actually cools a room without blowing a hole in your wallet is the real challenge of summer. Many budget-focused air conditioners skimp on BTU output, use inefficient compressors, or produce noise levels that make sleep impossible, leaving you with a warm, noisy box instead of a relief from the heat.

I’m Rikta — the co-founder and writer behind FitlyFast. I’ve spent countless hours analyzing cooling specs, energy efficiency ratings, and real-user feedback to separate the truly effective cheap air conditioners from the ones that just feel like a fan with a fancy grill.

After combing through over 2,000 verified customer reviews and cross-referencing BTU ratings, noise levels, and installation requirements, I’ve built this guide to help you confidently choose the right cheap air conditioner for your space, sleep quality, and summer sanity.

How To Choose The Best Cheap Air Conditioner

Picking a low-cost AC unit isn’t just about the lowest sticker price. You need to match the machine to your room size, noise tolerance, and willingness to install a window bracket. Here’s what matters most when hunting for a deal that actually works.

Match BTU to your room’s square footage

BTU (British Thermal Units) measures raw cooling power. A 5,000 BTU unit handles up to 150 square feet, while an 8,000 BTU unit covers up to 350 square feet. Oversizing wastes energy and causes short-cycling (frequent on/off) that fails to dehumidify properly. Undersizing forces the compressor to run constantly, spiking your electric bill without ever making the room truly comfortable.

Rule of thumb: For a standard bedroom, 5,000–6,000 BTU is plenty. For a combined living-dining area, look at 8,000 BTU or higher. Always measure your actual space — don’t guess.

Check the CEER, not just the price tag

Combined Energy Efficiency Ratio (CEER) tells you how much cooling you get per watt of electricity. A CEER of 11.0 is the baseline for decent budget units. Anything lower will cost you more in monthly bills, quickly eating up the initial savings. Look for units with an Eco Mode or Sleep Mode that adjusts compressor activity to further cut energy waste during off-peak hours.

Decide between window units and portable units

Window units are usually cheaper, more energy-efficient, and easier to install in standard double-hung windows. Portable units offer flexibility for rooms without a suitable window and can be moved between spaces, but they are typically louder (compressor sits inside the room), have lower CEER ratings due to heat recirculation from the exhaust hose, and cost more upfront. For a pure “cheap” goal, a window unit almost always wins on value unless you absolutely cannot install one.

Confirm the noise level before you buy

Noise is measured in decibels (dB). A unit rated at 50–52 dB on low is acceptable for a living room, but for a bedroom you want something at or below 48 dB to avoid sleep disruption. Many budget units achieve good dB ratings on paper but run louder in practice once the compressor kicks in. Reading recent reviews for “loud” or “noise” complaints is essential before finalizing your choice.

1. Midea EasyCool 5,000 BTU Window Air Conditioner

Window UnitRemote Control
Midea EasyCool 5,000 BTU Window Air Conditioner$176.00as of Jul 16, 1:32 AM

Get It On Amazon

This Midea unit delivers a solid 5,000 BTU of cooling for spaces up to 150 square feet, hitting the sweet spot between price and performance. The 3-in-1 design (cool, fan, dehumidifier) adds real versatility for sticky summer days. At just 52 dB on low mode, it’s quiet enough for light sleepers who want a gentle hum in the background. The included remote and intuitive LED display make it easy to adjust temperature or switch modes without getting up.

Owners consistently praise how quickly it drops the temperature in a standard-sized bedroom, with several noting it keeps the room comfortable even during peak afternoon heat. The reusable, washable filter is a nice convenience for ongoing maintenance. Some users report that the side accordion panels feel a bit flimsy, and the unit lacks vertical airflow direction, which can limit how effectively it distributes cold air across the room.

Overall, the Midea EasyCool strikes an excellent balance of features, quiet operation, and genuine cooling power for the money. The dehumidifier mode adds value for muggy climates, and the energy-efficient Eco mode helps keep bills manageable. It’s a strong choice for anyone wanting a reliable window unit without unnecessary frills.

Why it’s great

  • Quiet 52 dB operation suitable for bedrooms
  • 3-in-1 cooling, fan, and dehumidifier modes
  • Modern LED display with full-function remote

Good to know

  • Side panels feel less durable than expected
  • No vertical airflow adjustment

2. LG LW5023 5,000 BTU Window Air Conditioner

Window UnitMechanical Controls
LG LW5023 5,000 BTU Window Air Conditioner$170.05$189.00as of Jul 16, 1:32 AM

Get It On Amazon

LG’s LW5023 is a volume winner. Rated at 50 dB on low mode, it’s one of the quietest 5,000 BTU window units on the market, making it a top candidate for bedrooms where noise is a dealbreaker. The mechanical rotary controls are refreshingly simple — no confusing digital menus, just straightforward knobs for fan speed and cooling. It uses eco-friendly R32 refrigerant and includes an Energy Save function that cycles the compressor to reduce electricity consumption.

Customer feedback consistently highlights its cooling performance, with many users reporting it easily chills a small bedroom or even a two-car garage. The washable slide-out filter makes monthly cleaning quick. The main trade-off is the lack of a remote — you have to reach the unit to adjust settings. Several buyers also note that while the noise is low-pitched and unobtrusive (like a box fan), it is not silent, so those who need absolute quiet may still want earplugs.

Installation requires two people for the initial fit, as the side panels are snug, but the included EZ Mount kit is straightforward. If you prioritize a proven brand, low noise, and no-fuss operation over smart features, this LG unit is a reliable workhorse that will serve you well for many summers.

Why it’s great

  • Very quiet 50 dB low mode for bedrooms
  • Simple mechanical controls with no menu maze
  • Proven LG reliability and build quality

Good to know

  • No remote control included
  • Installation is tricky solo due to tight side panels

3. ACHAZEL 6,000 BTU Window Air Conditioner with WiFi

Window UnitWiFi / App Control
ACHAZEL 6,000 BTU Window Air Conditioner with WiFi$199.99as of Jul 16, 1:32 AM

Get It On Amazon

This ACHAZEL unit brings smart-home convenience to the budget tier with full WiFi and app control via the SmartLife-SmartHome platform. At 6,000 BTU it covers rooms up to 250 square feet, and the CEER rating of 11.0 means it won’t waste electricity. The three fan speeds, cooling/dry/fan/auto modes, and a 24-hour timer give you granular control. The ability to turn the AC on from your phone before you walk in the door on a hot day is a genuine quality-of-life upgrade.

Reviewers frequently mention the unit’s strong cooling output and the convenience of the remote and app working seamlessly. The washable filter and easy installation kit add to the value. The major negative is that a small number of units arrived defective, and the seller’s customer support was unresponsive in those cases. Some users also report that the actual power draw is higher than advertised, which could be an issue for solar-powered setups. Noise levels are comparable to a 5,000 BTU unit, so it’s not silent but not obtrusive.

If you want app control without paying a premium, this is a compelling option — provided you buy from a source with easy returns. It’s a mid-range unit with premium features, but the quality control inconsistency is a risk worth noting.

Why it’s great

  • Full WiFi and app control at a budget-friendly price
  • Covers up to 250 sq. ft. with 6,000 BTU output
  • CEER 11.0 for decent energy efficiency

Good to know

  • Some units arrive defective; seller support is poor
  • Power draw may be higher than listed specifications
Mid-Range Pick

4. Frigidaire 6,000 BTU Window Air Conditioner

Window UnitRemote + Eco Mode
Frigidaire 6,000 BTU Window Air Conditioner$195.99$279.00as of Jul 16, 1:32 AM

Get It On Amazon

Frigidaire’s 6,000 BTU unit comes with features typically reserved for more expensive models, including 6-way directional airflow, a 24-hour on/off timer, and a dedicated Dry Mode for humidity control. The Clean Filter alert is a thoughtful touch that reminds you when maintenance is due. Rated at 52 dBA, it’s quiet enough for most bedrooms and small living rooms up to 250 square feet. The Sleep Mode gradually adjusts temperature overnight, which helps both comfort and energy savings.

Long-term owner reviews are mixed: many praise its build quality and consistent cooling, with some units still going strong after two years. However, a significant number of one-year reviews report the compressor failing, leaving the unit blowing warm air. The noise level is also a point of contention — while the spec sheet says 52 dBA, several users describe it as loud enough to disrupt sleep, especially on higher fan speeds. The lack of a phone app is a missed opportunity compared to the ACHAZEL.

When it works, this Frigidaire delivers polished performance and thoughtful convenience features. The variable reliability means it’s a riskier recommendation for long-term use, but if you catch it at a good price and keep your warranty handy, it can be a solid year-to-year solution.

Why it’s great

  • 6-way directional airflow for better room coverage
  • Dry Mode + Sleep Mode for humidity and overnight comfort
  • Clean Filter alert for easy maintenance

Good to know

  • Reported compressor failures after 1-2 years
  • Noise level is higher than spec in real-world use for some

5. Hykolity 6,000 BTU WiFi Enabled Window Air Conditioner

Window UnitWiFi + App Control
Hykolity 6,000 BTU WiFi Enabled Window Air Conditioner$199.99as of Jul 16, 1:32 AM

Get It On Amazon

The Hykolity WiFi unit is essentially the same hardware platform as the ACHAZEL but sold under a different brand. You get the same 6,000 BTU cooling, 250 sq. ft. coverage, and SmartLife-SmartHome app compatibility. The standout claim from actual owners is the cooling intensity — several describe it as “super cold,” and one user noted it outperformed their previous 12,000 BTU unit in maintaining a lower room temperature. The CEER rating of 11.0 and Eco/Sleep modes help keep energy costs in check.

Installation is straightforward for standard double-hung windows, though the unit is heavier than a 5,000 BTU model. The remote is basic but functional. The most common complaint is that the unit defaults to ECO mode on startup, causing the compressor to cycle on and off frequently — there is no way to bypass this behavior in the settings. The sliding seal panels are described as cheap-feeling, but many users replace them with custom-fit plywood for a better seal. Noise is standard for a 6,000 BTU unit, not silent but tolerable.

If you want raw cooling power with smart control and don’t mind the ECO-mode quirk, this Hykolity delivers impressive performance for the money. It’s best suited for users who can work around the minor default behavior to get sensational cold air.

Why it’s great

  • Remarkably strong cooling output, even outperforms larger units
  • WiFi and app control for remote adjustments
  • CEER 11.0 with Eco and Sleep modes

Good to know

  • Defaults to ECO mode with no bypass option
  • Side panels feel flimsy; upgrade recommended

6. EUHOMY 8,000 BTU Portable Air Conditioner

EUHOMY 8,000 BTU Portable Air Conditioner$199.99$229.99Limited time dealas of Jul 16, 1:32 AM

EUHOMY’s portable offering packs 8,000 BTU of cooling power into a compact, wheeled chassis that covers up to 350 square feet. The 4-in-1 functionality — cooling, dehumidifier (51 pints/day), fan, and sleep mode — makes it a versatile companion for apartments, dorms, or rooms where window installation is impossible. The noise level on low is rated at 50 dB, which is competitive for a portable unit, and the display light can be turned off for sleep.

Customer reviews are broadly positive, with many appreciating how quickly it drops the temperature in a medium-sized room. The included window kit fits both sliding and double-hung windows from 20 to 50 inches. The biggest knock is that the fan cycles on and off with the thermostat, which some users find disruptive during sleep. A few owners report that it struggles to cool rooms above 300 square feet, and the compressor noise can be more noticeable than expected. The unit is heavy at over 50 lbs, so moving it between rooms is possible but not effortless.

For the money, this EUHOMY delivers good portable cooling with useful dehumidification. It’s ideal for renters or anyone needing flexibility, as long as you set realistic expectations about noise and cooling coverage.

Why it’s great

  • Powerful 8,000 BTU cooling for rooms up to 350 sq. ft.
  • Includes dehumidifier, fan, and sleep modes
  • Rolls easily on 360° casters

Good to know

  • Fan cycles on/off with thermostat; can disrupt sleep
  • Heavy (50+ lbs) despite being portable
Quiet Portable

7. Feelfunn 8,000 BTU Portable Air Conditioner

Portable48 dB Low Noise
Feelfunn 8,000 BTU Portable Air Conditioner$239.99as of Jul 16, 1:32 AM

Get It On Amazon

Feelfunn focuses on keeping things quiet with a claimed noise level of just 48 dB on low, making it one of the quieter portable units at this BTU level. It still delivers 8,000 BTU for rooms up to 350 square feet and includes a 3-in-1 function set (cool, fan, dehumidifier removing up to 45 pints/day). The compact dimensions (12” x 11.4” x 26.7”) and 41.5 lb weight mean it fits into tighter spaces and is easier to wheel around than many competitors.

Users generally confirm the cooling is powerful and fast, with the digital climate control maintaining a steady 72°F even during hot spells. The sleep mode adjusts temperature to save energy while you rest. The main complaint is that the actual noise level is significantly higher than advertised for some units — several third-party measurements show 60+ dB on low, which is too loud for a bedroom. The CEER rating of 6.1 is also low compared to window units, meaning higher electricity costs. The 6-inch exhaust hose is larger than standard, which could complicate replacement if damaged.

For daytime use in a living room or home office, the Feelfunn provides solid cooling at a fair price. But if you need it for sleeping, be prepared for potential noise that exceeds the spec sheet promise. Check recent reviews carefully for noise complaints before purchasing.

Why it’s great

  • Compact and relatively lightweight for an 8,000 BTU portable
  • Sleep mode and 24-hour timer for energy savings
  • Includes full water-alert system to prevent spills

Good to know

  • Real-world noise may be louder than 48 dB claimed
  • Lower CEER 6.1 leads to higher energy consumption

Uhome’s 8,000 BTU portable unit is a solid entry-level option for anyone needing flexible cooling without the complexity of window installation. It cools up to 350 square feet and offers three modes: cooling, dehumidifier (40 pints/day), and fan. The self-evaporating operation means you rarely need to drain a bucket manually — a major convenience for daily use. The noise level is rated at less than 55 dB, which is average for a portable but not silent.

Owners who’ve used the unit for a full year report that it maintains strong cooling performance, with one user noting it still works perfectly after 12 months of 24/7 use. The 24-hour timer, remote control, and washable filter add to the value. The biggest downside is the noise — it’s described as very loud by multiple reviewers, especially on higher fan speeds. The LED display is bright and cannot be dimmed, which can be annoying in a dark bedroom. The window kit is basic and may not fit larger windows without modification.

If you need an affordable portable unit for daytime use in a small to medium room, the Uhome gets the job done. For overnight sleep, the noise and bright display are likely dealbreakers. Good warranty support from the seller makes it a relatively safe bet.

Why it’s great

  • Self-evaporating design minimizes manual draining
  • Proven long-term durability reported by owners
  • Includes remote, timer, and washable filter

Good to know

  • Noise level is loud; not ideal for sleep
  • Bright LED display cannot be dimmed or turned off

The Electactic 5,000 BTU window unit is the most budget-conscious option in this lineup, designed for compact rooms up to 150 square feet. It offers 7 adjustable temperature levels (61°F–81°F), two cooling and two fan speeds, and mechanical rotary controls that are dead-simple to use. With a CEER of 11.0 and R32 hydrocarbon refrigerant, it’s both energy-efficient and environmentally friendlier than older refrigerants. The noise level of 51 dB is competitive for the category.

Customer reviews are generally strong: users appreciate how quickly it cools a small room, with one noting it dropped the temperature from 89°F to 60°F in under two hours. The included remote control is a nice surprise at this price point. On the downside, some units arrive with cosmetic damage like dents or scratches, though functionality is rarely affected. The remote requires a tiny screwdriver to access the battery compartment, which is a minor annoyance. A few users feel the cooling is adequate but not exceptional for rooms on the larger end of its rating.

For the lowest entry fee into a functional window AC, the Electactic delivers solid cooling, decent efficiency, and a remote — all things that usually cost more. The cosmetic damage reports are worth noting, but if you can accept that, this is a legitimately good value.

Why it’s great

  • Lowest price point with a functional remote included
  • CEER 11.0 rating keeps energy costs low
  • Quick cooling performance for rooms under 150 sq. ft.

Good to know

  • Some units arrive with minor cosmetic imperfections
  • Remote battery compartment needs a tiny screwdriver

FAQ

How many BTU do I need for a standard 12×12 bedroom?
A 12×12 room is 144 square feet. A 5,000 BTU unit is perfectly sized for this space. If your bedroom has high ceilings, lots of direct afternoon sun, or you live in a very hot climate, consider moving up to a 6,000 BTU unit to ensure the room stays comfortable during peak heat.
Is a portable air conditioner worth it over a window unit for a similar price?
Generally, no — if you have a standard double-hung window, a window unit is more energy-efficient (higher CEER), quieter (compressor is outside), and cheaper to run. Portable units only make sense when window installation is physically impossible (casement windows, sliding doors, HOA rules) or when you need to move the unit between rooms frequently.
What does CEER mean and why should I care on a cheap air conditioner?
CEER stands for Combined Energy Efficiency Ratio. It measures how many BTU of cooling you get per watt of electricity. A higher CEER means lower monthly electric bills. For a budget unit, look for a CEER of 11.0 or higher. Every 1-point drop in CEER can add roughly 5–10% to your cooling bill over a summer. The savings from a cheap unit can vanish fast if its CEER is low.
Can I leave a window air conditioner running 24/7?
Yes, modern window ACs are designed for continuous operation. However, running a unit 24/7 will significantly increase your electricity bill and may shorten the compressor’s lifespan. Use the timer or Eco/Sleep modes to give the compressor breaks during cooler parts of the day or while you’re away. Also, clean or replace the filter monthly to maintain airflow and efficiency during continuous use.

Final Thoughts: The Verdict

For most users, the cheap air conditioner winner is the Midea EasyCool 5,000 BTU because it combines quiet 52 dB operation, a useful dehumidifier mode, and a modern remote control at a price that undercuts the competition. If you want ultra-simple controls and the quietest possible 5,000 BTU unit, grab the LG LW5023. And for those who need smart-home WiFi control without paying a premium, the ACHAZEL 6,000 BTU WiFi delivers strong cooling and app convenience that no other budget unit matches.
