Ethan Caldwell Finding the best air conditioners for apartments is about more than raw cooling power. Renters have to work around fixed windows, shared walls, tight square footage, noise limits, and lease rules that often ban permanent installations. The good news is that today’s apartment-friendly units deliver serious comfort without a contractor, a mini-split, or a hole in the wall. This guide walks you through how to choose the right air conditioner for your apartment, what BTU rating you actually need, and which types of units make the most sense for small-space living.
Instead of drowning you in per-model reviews, we focus on the buying decisions that matter: sizing, unit type, installation, noise, and energy use. Along the way we point to specific apartment-ready models so you can jump straight to the products that fit your space.
Why Choosing the Right Apartment AC Matters
An apartment is a uniquely tricky environment to cool. You might be on a top floor that traps heat, sharing thin walls with neighbors who hear every rattle, or dealing with a landlord who won’t allow anything bolted to the building. On top of that, an oversized unit cools the air too fast without removing humidity, leaving the room cold and clammy, while an undersized one runs constantly and never quite catches up.
Getting the match right means lower energy bills, quieter nights, and a cooling setup you can pack up and take with you when your lease ends. That portability and flexibility is exactly why the best air conditioners for apartments tend to be portable and window units rather than fixed central systems.

Pros
- Ultra-powerful ice cool system with 16 foot coverage area
- Patented noise isolation system reduces noise to 45dB
- True drainage-free system with automatic water evaporation
- Smart climate control via app and voice commands
- 3-in-1 cool fan and dehumidifier combined
Cons
- Portable unit requires adequate room for placement
- Hose connection needed for drainage in humid areas
With a 42-inch blade span and powerful DC motor, this ceiling fan efficiently cools large rooms up to approximately 400 square feet. The reversible motor switches from downward summer airflow to upward winter circulation, adapting to seasonal heating and cooling needs.
- Summer mode pushes cool air downward suitable for living rooms, bedrooms, and open-plan spaces.
- Gentle speeds 1-2 provide subtle air circulation ideal for bedrooms where strong breezes disrupt sleep.
- Maximum speeds 5-6 deliver powerful airflow for large rooms with high ceilings or poor natural ventilation.
- Winter mode reverses blade rotation to push warm air downward from ceiling heights, improving heat distribution.
Professional installers recommend this fan size for rooms larger than 300 square feet. Effective cooling without constant maximum-speed operation that wastes electricity and increases energy costs significantly.
The DC motor operates significantly quieter than traditional AC induction motors, producing minimal noise even at higher speeds. This silence makes the fan suitable for bedrooms, home offices, and nurseries where ambient noise causes distraction.
- Energy-efficient DC motor uses 40-50 percent less electricity than comparable AC ceiling fans over yearly operation.
- Quiet operation under 25 decibels allows conversation and television viewing without competing noise.
- Motor lifespan extends beyond typical ceiling fans due to brushless DC design with fewer moving parts.
- Variable speed settings allow running at lower speeds for background airflow, reducing power consumption.
The quieter operation and energy efficiency often justify the higher initial cost through reduced electricity bills. Some users report saving enough on utility costs over the fan lifespan to recoup investment completely.
Integrated LED lighting with stepless dimming provides adjustable illumination from 10 percent to 100 percent brightness. Three selectable color temperatures match the lighting to your activity and time of day for enhanced comfort and mood.
- Warm white 3000K mimics sunset lighting, signaling your body to wind down for improved sleep quality.
- Neutral white 4500K provides balanced illumination suitable for working, reading, and household activities.
- Cool white 6500K simulates daylight, boosting alertness and focus during morning hours or work.
- Timer function allows scheduling automatic fan off or fan-only operation without lights after sleep.
The color temperature flexibility appeals to people managing circadian rhythms and seasonal mood changes. Gradually shifting lighting mimics natural day-night cycles that improve sleep and productivity throughout the year.
Pros
- 9,500 BTU SACC covers rooms up to about 500 square feet, with dual hoses drawing condenser air from outside rather than the room
- 71 pints per day of moisture removal with a patented auto-drain that exhausts condensate in most conditions
- 51 dBA on the low fan speed, quiet enough to leave running overnight in a bedroom
- Thermostat spans 61 to 89 F across cool, dehumidify and three-speed fan modes, moving 253 CFM
- Ships with a 20 to 46 inch window panel, twin 5.9 inch hoses, a carbon filter, a washable pre-filter and a storage bag
Cons
- Draws up to 1300 W at 11.6 A on a 115 V supply, so sharing a breaker with a heater or kettle will trip it
- Stands 35.5 inches tall on a 19 by 16 inch footprint and needs floor space beside a window, not a corner
- The supplied window panel spans 20 to 46 inches, so casement and very wide sliding windows need a custom-cut board
This is a 14,000 BTU machine measured the older way and 9,500 BTU under the SACC standard, which accounts for duct and infiltration losses. SACC is the figure to compare against other portable units.
- Suited to rooms up to roughly 500 square feet
- Dual hoses draw condenser air from outside instead of the room, so conditioned air is not pulled back out through door gaps
- Airflow reaches 253 CFM, or 430 cubic metres per hour
- Thermostat spans 61 to 89 F across cool, dehumidify and three fan speeds
The dual-hose layout is the meaningful difference from single-hose portables, which depressurise a room and draw warm outside air in through every gap. In a sunlit top-floor room, the gap between the two designs is large.
Everything needed for a standard sash window fit is in the box.
- An extendable window panel 6.5 inches wide, adjusting from 20 to 46 inches long
- Two 5.9 inch diameter hoses extending to about 60 inches
- An activated carbon filter plus a washable pre-filter
- A storage bag for the off-season
Plan the position first. The cabinet stands 35.5 inches tall on a 19 by 16 inch footprint and must sit close enough to the window for the hoses to reach without stretching, which usually means floor space beside the glass rather than a tucked-away corner. Casement, awning and very wide sliding windows fall outside the supplied panel range and need a custom-cut board. Foam tape along the panel edges improves the result noticeably.
Sound sits at 51 dBA on the low fan speed, quiet enough to leave running overnight, and rises with fan speed and compressor cycling.
- Maximum draw of 1300 W at 11.6 A on a 115 V, 60 Hz single-phase supply
- Runs on CFC-free refrigerant
- 71 pints per day of moisture removal in dehumidify mode
The patented auto-drain function exhausts condensate through the exhaust airstream in most conditions, so there is no bucket to empty day to day; in very humid weather the drain port may still need connecting. On the electrical side, 11.6 A sits close to the ceiling of a 15 A circuit, so avoid sharing the breaker with a heater, kettle or hair dryer, and plug into the wall rather than an extension lead.
Pros
- 8000 BTU ASHRAE, listed as 5000 BTU DOE, with cooling reach quoted to 14 ft
- Condensate is evaporated automatically, so no bucket needs emptying below 90 percent humidity
- Compressor and turbulence noise drop to 45 dB on the lowest setting for overnight use
- Cool, fan and dry modes in one 15.16 in by 13.98 in floor footprint
- Controlled four ways: touchpad, remote, app, or voice through Siri, Alexa and Google Home
Cons
- 5000 BTU DOE suits a bedroom or study, not an open-plan living room
- A single exhaust hose must vent through a window, so the unit stays tied to that wall
- Above 90 percent humidity the included drain hose has to be fitted, ending the hands-off claim
Two figures describe the same machine. 8000 BTU ASHRAE is the older test standard, while 5000 BTU DOE is the newer measure that accounts for heat leaking back through the hose. Size your room against the DOE number.
- Cooling reach is quoted to 14 ft from the unit
- The target temperature can be set anywhere between 61 and 86 degrees Fahrenheit
- Cool, fan and dry modes each carry three sub-settings, with high, mid, low and auto fan speeds
- Listed SEER for this model is 6.1
In practice this suits a bedroom, a home office or a study with the door closed. An open-plan lounge or a sun-facing room with large windows will need a larger unit to hold temperature through an afternoon.
Like all portable units, this one moves heat outdoors through a hose, so a window is required. Fitting the window kit is the first job and the one that decides how well it performs.
- Seal gaps around the window bracket; leaked warm air undoes a large share of the cooling
- Keep the hose as short and straight as the layout allows, since bends radiate heat back into the room
- The drainage-free system evaporates condensate automatically below 90 percent humidity, so there is no tray to empty
- Above 90 percent humidity, fit the supplied drain hose and route it to a floor drain or a shallow tray
The cabinet stands 24.8 in tall on a 15.16 by 13.98 in base, so leave clear floor space near the window rather than in a corner.
Noise is the deciding factor for a bedroom unit. This one is quoted at 45 dB at its lowest setting, using an isolation system aimed at both compressor rumble and airflow turbulence.
- Four control routes: the on-unit touchpad, the bundled remote, the DREO app and voice assistants
- Siri, Amazon Alexa and Google Home are all supported for spoken commands
- The app shows room temperature and humidity, and holds a customisable sleep curve that eases the set point overnight
- An LED display with a light control keeps the panel from glowing across a dark bedroom
Expect the 45 dB figure to apply on the lowest fan speed with the compressor settled. Higher speeds are louder, as with any portable unit that houses the compressor in the room with you.
Pros
- 6,000 BTU cools rooms up to 250 sq ft, about a 10 by 25 ft bedroom or home office
- Sound levels drop as low as 52 dB on the low setting, quiet enough to sleep beside
- Plugs into an ordinary 115V household outlet, with no dedicated circuit and no electrician
- Auto restart returns the unit to its previous settings after a power cut
- Slide-out washable filter with a reminder light, plus a fitting kit and remote in the box
Cons
- Cooling only, with no heat mode for shoulder seasons
- No Wi-Fi or app control, so scheduling happens on the panel or the handset
- The listing quotes both two and three fan speeds in different places, so confirm the exact model before ordering
At 6,000 BTU this unit is specified for rooms up to 250 sq ft, which the manufacturer illustrates as roughly a 10 by 25 ft space. That is a bedroom, a home office, a den or a small living room.
Match the capacity honestly, because the failure modes run in both directions. Undersized in a large or sun-facing room, the compressor runs constantly and never reaches the set temperature. Oversized in a small room, it cools fast, shuts off early and leaves the air clammy, because it never runs long enough to pull real moisture out of the room.
Two-way air deflection lets you aim the flow left or right rather than accepting wherever the vanes default to, which matters when the only usable window is not in line with the bed or the desk.
The chassis measures 14.38 inches deep, 17.31 inches wide and 11.13 inches high, and an installation kit is supplied. Measure the window opening width and the sash height before ordering; a standard double-hung window is the intended fit, and casement or sliding windows need a different style of unit entirely.
Power is 115V from an ordinary household outlet, so there is no electrician and no dedicated 220V circuit involved. Use a wall outlet directly rather than an extension lead.
The lift is a two-person job even at this size. Tilt the unit very slightly toward the outside so condensate drains away from the room rather than back onto the sill, secure the sash lock and the side panels, then seal the remaining gaps with the supplied foam to stop warm air leaking back in around the frame.
Sound levels go as low as 52 dB on the low setting, roughly the level of a quiet conversation and low enough to sleep through once you are used to it. Higher fan settings are correspondingly louder, so that quiet figure applies to the mode you will use overnight rather than the one that cools the room fastest.
Maintenance centres on the slide-out washable filter. Pull it out, rinse it, let it dry completely and slide it back; a filter reminder light tells you when it is due. A clogged filter is the most common cause of weak airflow and climbing energy use in a window unit.
Controls run from a digital panel and the included handset, with a 24-hour timer and an auto restart that recovers the previous settings after a power cut.
Pros
- Rated to cool spaces up to 150 sq ft, suited to a bedroom or single home office
- Runs as low as 52dB on low mode, quieter than many window units near 60dB
- Reusable air filter removes dust and pet hair without recurring filter purchases
- 3-in-1 design combines cooling, a 3-speed fan, and a dehumidify mode in one unit
- Backed by a 1-year parts and labor warranty
Cons
- 150 sq ft coverage limits it to a single small-to-medium room, not open-plan spaces
- Installation needs a screwdriver, which is not included in the box
- Only compatible with double-hung or slider windows sized within the included mounting kit
This Midea unit is rated at 5,000 BTU, enough to cool a space up to 150 square feet, which typically covers a single bedroom or a small home office rather than an open living area. Sound output is rated as low as 52dB on the low fan setting, quieter than many window units that sit closer to 60dB at similar output.
- 5,000 BTU cooling capacity
- Covers up to 150 sq ft
- 52dB minimum noise level on low mode
- 3-speed fan for adjustable airflow
Anyone cooling a larger open-plan room or a space over 150 sq ft will need a higher-BTU unit, since pushing this one beyond its rated coverage means longer run times and less consistent temperatures.
The unit measures 13.19 inches deep, 15.98 inches wide, and 12.05 inches tall, and ships with mounting accessories designed for standard double-hung or slider window frames. A screwdriver is required to complete the install but is not included, and the manufacturer recommends drilling pilot holes for some window frame types before setting the mounting screws.
- 13.19"D x 15.98"W x 12.05"H unit size
- Mounting hardware included
- Screwdriver required, not supplied
- Expandable side panels for various window widths
Casement or crank-style windows that don't open with a vertical or horizontal slide are not compatible with this style of mounting kit.
Controls run through an LED display and included remote, covering temperature, fan speed, and mode selection from across the room. Beyond straight cooling, the unit offers a fan-only mode for air circulation without cooling and a dehumidify mode for reducing humidity without dropping the room temperature as far.
- LED display with remote control
- 3 core modes: cool, fan, dehumidify
- Reusable, washable air filter
- 1-year parts and labor warranty
The washable filter cuts down on replacement filter purchases, but it still needs regular rinsing and full drying before reinstalling, and skipping that maintenance step reduces airflow over time.
Pros
- Rated for up to 150 sq ft of room coverage at 5000 BTU, suited to bedrooms or small home offices
- Operates as low as 50dB in low mode, quieter than many window units in the same BTU class
- Washable filter slides out for cleaning, recommended every 30 days, without disposable filter replacement
- Fixed chassis installs into double-hung windows sized 21" to 35" wide using the included EZ Mount kit
- Auto-restart resumes previous settings automatically after a power outage
Cons
- Fixed-chassis design fits only double-hung windows within the 21"-35" width range, not sliding or casement windows
- 2 fan speeds and 2 cooling modes offer fewer settings than higher-BTU units with 3-4 speed options
- 150 sq ft coverage limits it to small rooms, not living rooms or open-plan spaces
This LW5023 model delivers 5,000 BTU of cooling, rated for spaces up to 150 square feet, a bedroom, nursery, home office or small dorm room rather than an open living area. It runs at a 60Hz frequency with 2 cooling modes and 2 fan speeds, giving basic control over airflow intensity rather than a wide range of settings. The unit uses R32 refrigerant, a more environmentally efficient choice than older refrigerant types still found in some entry-level window units. An Energy Save function cycles the compressor to reduce electricity draw once the room reaches the set temperature.
- Cooling capacity: 5,000 BTU
- Coverage: up to 150 sq ft
- Refrigerant: R32
At 150 sq ft, this unit is sized for one small room rather than cooling an adjoining space through an open doorway.
The fixed-chassis design is built specifically for double-hung windows measuring 21" to 35" wide by at least 12" high, and the included EZ Mount kit provides the hardware needed for a standard installation without buying separate brackets. Unit dimensions are 14.37"D x 17.32"W x 11.14"H, sized to sit within a typical window sash without protruding far into the room. Because the chassis is fixed rather than the slide-out type used in some other window units, installation and removal both happen as a single assembly rather than splitting the housing from the cooling unit.
- Fits double-hung windows, 21"-35" wide
- EZ Mount installation kit included
- Unit size: 14.37"D x 17.32"W x 11.14"H
Sliding or casement windows are not compatible with this fixed-chassis mounting system, so window type should be confirmed before ordering.
Sound levels as low as 50dB in low mode are quiet enough for a bedroom overnight compared with louder window units in the same BTU class. The washable filter slides out from the front without tools and is recommended for cleaning every 30 days to keep airflow and cooling efficiency consistent. Auto-restart is built in, so the unit resumes its previous cooling mode and fan speed automatically after a power interruption rather than needing to be reprogrammed each time.
- Sound level as low as 50dB in low mode
- Washable filter, recommended cleaning every 30 days
- Auto-restart after power loss
Regular filter cleaning is manual upkeep the owner has to keep on a schedule, since there is no filter-clean reminder alert on this model.

Pros
- 8,000 BTU capacity covers rooms up to 350 sq ft (14' x 25'), suited to a large bedroom or small living room
- Operates as low as 53dB on low mode, quieter than the 60dB-plus typical of standard window units
- Auto Restart returns to prior settings automatically after a power outage, no manual reset needed
- 3 cooling and fan speeds plus remote control give more granular adjustment than single-speed units
Cons
- At 19.57 in W x 19.38 in D x 12.33 in H, it needs a window opening sized to fit, plus support brackets for larger installations
- 8,000 BTU capacity means rooms over roughly 350 sq ft will cool slower or less completely
- 115V standard plug only, no 230V option for circuits that require it
Rated at 8,000 BTU, this unit is built for rooms up to about 350 square feet, roughly a 14 by 25 foot space such as a large bedroom or a small living area. Three cooling and fan speeds plus an Auto Cool mode allow the output to be dialed down for smaller rooms or milder days rather than running at full capacity constantly.
- 8,000 BTU cooling capacity
- Covers rooms up to 350 sq. ft.
- 3 cooling and fan speeds, plus Auto Cool
Rooms larger than the covered area will take longer to cool and may not reach a consistent temperature during peak heat.
The unit measures 19.57 inches wide, 19.38 inches deep, and 12.33 inches high, sized for a standard double-hung window opening. It ships with a window installation kit, though larger or unusually shaped window frames may need additional support brackets purchased separately from a hardware store.
- 19.57 in W x 19.38 in D x 12.33 in H
- 115V standard household outlet
- Removable, washable air filter
Auto Restart brings the unit back to its previous settings automatically after a power interruption, so schedules and modes do not need re-entry.
On low fan mode, this unit operates at around 53dB, quieter than many window units that run closer to 60dB or above at similar cooling capacities. Electronic controls paired with an included remote allow speed and mode changes from across the room instead of at the unit itself.
- As low as 53dB on low mode
- Included remote for electronic controls
- 3 fan speeds plus Auto Cool mode
The lower noise floor makes it a reasonable fit for bedrooms, though it will not be silent at higher cooling speed settings.
If you want a truly quiet, energy-sipping window unit, the Midea U-Shaped Inverter AC is a standout thanks to its unique design that lets you close the window over the middle of the unit. For renters who can’t use a window at all, a self-evaporating portable like the DREO 515S Portable AC offers drainage-free cooling and smart app control.
How to Choose the Best Air Conditioner for Your Apartment
1. Match BTU to Room Size
BTU (British Thermal Units) measures cooling capacity. Too few and the room stays warm; too many and you waste money while leaving the air damp. A rough starting point:
- 150 sq ft or less (small bedroom, home office): 5,000 BTU. A compact unit like the Midea 5,000 BTU Window AC or the LG 5,000 BTU Window AC is ideal.
- 150-250 sq ft (standard bedroom, den): 6,000-8,000 BTU. The LG 6,000 BTU Window AC hits the sweet spot for a single room.
- 250-400 sq ft (large bedroom, studio, living room): 8,000-10,000 BTU. Consider the LG 8,000 BTU Window AC or the Midea U-shaped unit.
- 400-700 sq ft (open-plan studios, large living rooms): 12,000-14,000 BTU. Larger portables cover this range comfortably.
Adjust upward if your apartment gets heavy afternoon sun, has high ceilings, or sits under a hot roof. If your space is on the larger side, our guide to the best air conditioner units for home covers higher-capacity options in more detail.
2. Pick the Right Type of Unit
The three types most relevant to apartment dwellers are window units, portable units, and U-shaped inverter units.
Window air conditioners are efficient and affordable, and they free up floor space. The tradeoff is that they block the window, need a compatible window frame, and can be heavy to lift into place. Traditional models like the LG LW5023 Window AC are reliable, budget picks for a single small room.
Portable air conditioners sit on the floor and vent hot air through a hose to a window kit. They’re the go-to for casement windows, sliding windows, or leases that forbid window installations. The Whynter ARC-14S Portable AC uses a dual-hose design for stronger, more efficient cooling in rooms up to 500 sq ft, while the BLACK+DECKER Portable AC includes a Follow Me remote that reads the temperature where you are.
U-shaped window units are a newer category built for apartments. The window sash closes down through a gap in the middle of the unit, which blocks outdoor noise and lets you keep using the window. The Midea U-Shaped Smart AC is the flagship here, running ultra-quiet and saving up to 37% on energy versus conventional window units.
If you’re weighing portable models specifically, our roundup of the best portable air conditioner units breaks down single- versus dual-hose designs in depth.
3. Consider Noise Levels
In an apartment, noise is not a minor detail. A loud compressor can keep you and your neighbors awake and make video calls miserable. Look for units advertising a sleep or quiet mode and check the decibel rating when it’s listed. Inverter-driven units like the Midea U-Shaped AC ramp the compressor up and down smoothly instead of cycling loudly on and off, making them among the quietest options. Portables such as the DREO 515S and its smaller sibling, the DREO 318S Portable AC, also prioritize low-noise operation for bedrooms.
4. Look at Energy Efficiency
Since renters usually pay their own electricity, efficiency directly affects your monthly bill. Inverter compressors, high CEER ratings, and ENERGY STAR certification all point to lower running costs. Smart features that let you schedule cooling or trigger an eco mode help you avoid cooling an empty apartment. Pairing an efficient AC with a smart thermostat can squeeze even more savings out of your setup during peak summer months.
5. Factor in Installation and Portability
Think about how the unit gets in, out, and stored. Window units need a window that fits and enough strength to lift a 40-to-60-pound box safely. Portable units roll on casters and are easier for one person to manage, but they take up floor space and require a nearby window for the exhaust hose. Both types are far more lease-friendly than anything permanent, and both can move with you.
Portable vs. Window Air Conditioners for Renters
The choice between portable and window comes down to your specific apartment. Choose a window unit if you have a standard double-hung window, want the best efficiency for the price, and don’t mind losing the view. A model like the LG 8,000 BTU Window AC cools a mid-size room reliably and costs less to run than a comparable portable.
Choose a portable unit if your windows are sliding or casement style, your lease bans window installations, or you want to wheel the cooling from room to room. Self-evaporating portables like the DREO 515S are especially convenient because they don’t require you to empty a water tank in most conditions.

Smart Features Worth Having
Many modern apartment air conditioners now include Wi-Fi and voice control. App scheduling lets you cool the apartment on your commute home so you walk into comfort instead of a hot box. Voice assistant support through Alexa or Google Assistant means you can adjust the temperature without getting up. The Midea U-Shaped Smart AC and the BLACK+DECKER Smart Portable AC both offer connected control, which is genuinely useful for setting a schedule that matches your day and trims energy waste.
Managing Humidity and Air Quality
Most portable and many window units double as dehumidifiers, pulling moisture out of the air as they cool. That’s a real benefit in humid climates or ground-floor apartments prone to dampness. Three-in-one portables that combine AC, fan, and dehumidifier modes, like the DREO models, give you year-round versatility. If persistent moisture is your main problem rather than heat, a dedicated dehumidifier may serve you better, and clean cooled air paired with one of the best air purifiers for bedrooms makes for a healthier, more comfortable space overall.
Frequently Asked Questions
What size air conditioner do I need for a small apartment?
For a small studio or a single bedroom under 300 sq ft, a 6,000-8,000 BTU unit is usually plenty. For open-plan studios or larger one-bedroom apartments up to 700 sq ft, step up to a 12,000-14,000 BTU portable. Measure your space and factor in sun exposure before deciding.
Can I use an air conditioner if my lease bans window units?
Yes. A portable air conditioner vents through a slim window kit that leaves no permanent marks and can be fully removed, making it the safest choice when your lease restricts window installations. Confirm the details with your landlord, but portables are widely accepted in rentals.
Are portable air conditioners less efficient than window units?
Generally, single-hose portables are a bit less efficient than window units of the same BTU rating because they draw some conditioned air out through the exhaust. Dual-hose portables like the Whynter ARC-14S close much of that gap and cool larger rooms more effectively.
How can I keep my apartment AC running quietly at night?
Enable sleep or quiet mode, choose an inverter-based unit, and place the AC away from the head of your bed. Inverter window units and low-noise portables are specifically engineered to keep bedroom noise to a minimum.
Final Thoughts
The best air conditioners for apartments balance cooling power, quiet operation, energy efficiency, and lease-friendly installation. Start by measuring your room and matching the BTU rating, then pick the unit type that fits your windows and rules. Renters with standard windows and a tight budget do well with an efficient window unit, while those with awkward windows or strict leases should lean toward a portable. Whichever direction you go, any of the apartment-ready models in our list above will keep your space comfortable all summer long without a permanent installation. Compare your top choices, check the fit for your window, and enjoy a cooler, quieter apartment this season.
