This guide lets bedroom shoppers see Cozeware’s sleep mode ratings alongside every other noise figure the brand lists, from 28 dB to 36 dB. Four mini splits are reviewed, with prices from $526.99 to $649.99 under the Autumn Sale banner. Readers also learn which details the listed numbers leave out.
Key Takeaways
- The quietest listed model is the E-Save 12,000 BTU at 28 dB in sleep mode.
- On the E-Save line, listed noise rises with size: 28, 32 and 36 dB.
- Match the room’s circuit to 115V or 230V; the Visio 18,000 BTU is 230V.
- Each model carries a 7 year compressor warranty, a 5 year parts warranty and 30 day returns.
A mini split that cools well but hums all night is hard to live with, so noise is often the first question for a bedroom. Cozeware sells ductless mini split air conditioners and heat pumps from 9,000 to 24,000 BTU, and the noise levels it lists across its models run from 28 dB to 36 dB. These are numbers rated by Cozeware, not a promise of silence, and they come from the brand’s own pages and a sponsored article rather than independent testing. The table in the next section puts every listed figure in one place, with the mode each number refers to where Cozeware states one.

What Cozeware Lists for Noise, Model by Model
Here is every noise figure Cozeware lists for the models covered in this post, with the mode each number refers to where the brand or its sponsored coverage states one. Where no mode is given, the table says so instead of assuming sleep mode. The lowest listed figure is 28 dB on the E-Save 12,000 BTU in sleep mode. The highest is 36 dB, listed on both the E-Save 24,000 BTU and the Visio 18,000 BTU.

Bigger Isn’t Quieter on the E-Save Line
On the E-Save line, a bigger unit lists a higher number: 28 dB at 12,000 BTU, 32 dB at 18,000 BTU and 36 dB at 24,000 BTU. The quietest listed E-Save is also the smallest, so chasing the lowest figure can leave a room undersized. The 12,000 BTU 115V models are listed for up to 750 sq ft, and the Visio 18,000 BTU for up to 1,250 sq ft. Start with the size your room needs, then compare noise figures within that size. This post does not include a sizing formula, so confirm coverage on the product page for the exact model.
Four Cozeware Mini Splits Worth a Look for a Bedroom
These four models span the noise range in the table above, from 28 dB on the E-Save 12,000 BTU to 36 dB on the Visio 18,000 BTU. Every figure is rated by Cozeware, so read them as listed numbers rather than tested results. Prices below are the sale prices shown on cozeware.com in October 2026 under the Autumn Sale banner, and they can change, so check the product page before you order.
E-Save Series 12000 BTU
This is the 12,000 BTU, 115V version of Cozeware’s E-Save line, and it carries the lowest noise figure the brand lists: 28 dB in sleep mode. It is listed for up to 750 sq ft, which makes it a fit for a single bedroom or small room rather than a whole floor. It is also a heat pump with an “AI Chip” and an AI optimized ECO mode, so the same unit covers heating and cooling.
- 28 dB listed in sleep mode, the lowest figure Cozeware lists across its models.
- 20 SEER2 cooling and 10 HSPF2 heating, with a listed operating range of 13°F to 140°F.

- Whole room 4D airflow and R32 refrigerant.
- Backed by a 7 year compressor warranty, a 5 year parts warranty and 30 day returns.

Visio Series 12000 BTU
This is the 12,000 BTU Visio, listed for up to 750 sq ft, which suits a single bedroom or similar room. It lists 31 dB for the indoor unit and ships with a complete installation kit that includes a 16.4 foot line set. It heats and cools, so one unit can cover both seasons in the same room.
- 31 dB listed for the indoor unit.
- Heating and cooling at 20 SEER2, with 4D airflow, for up to 750 sq ft.
- Complete installation kit with a 16.4 foot line set. Electrical and refrigerant work is still required.

Enduring Series 12000 BTU
This is the 12,000 BTU Enduring, a heat pump listed for up to 750 sq ft, which suits a bedroom or similar single room. Cozeware lists 31 dB in sleep mode for it, and it adds app and voice control. Enduring is the line where the homepage lists its lowest starting price, $399.99 for the 9,000 BTU 115V model.
- 31 dB listed in sleep mode.
- 20 SEER2 cooling and 8.5 HSPF2 heating, with 4D airflow, for up to 750 sq ft.

Visio Series 18000 BTU
This is the larger Visio, listed for up to 1,250 sq ft, which suits a big bedroom, a primary suite or an open room that a 12,000 BTU unit would cover poorly. It is the 230V version of the model, so check your home’s electrical setup before ordering. Cozeware lists 36 dB for it, the highest figure among the four models covered here, which is the trade off for the added coverage.
- 36 dB listed, with no mode stated.
- Heating and cooling at 20 SEER2 and 8.5 HSPF2 for up to 1,250 sq ft.
- WiFi, app, voice control and a remote, with R32 refrigerant.

What the Listed Numbers Don’t Tell You
A dB figure is only as useful as the detail behind it. For the E-Save 18,000 and 24,000 BTU models and the Visio 18,000 BTU, Cozeware lists 32 dB, 36 dB and 36 dB without naming a mode, and the Visio 12,000 BTU figure of 31 dB refers to the indoor unit. We could not confirm the test conditions behind any of these numbers, or how loud the outdoor unit is. Before you buy, read the specification section of the product page for the exact model, and ask Cozeware’s customer service for the test conditions and the outdoor unit figure. Cozeware also lists 30 day returns.
What Buyers Say About the Quiet
On Trustpilot, Cozeware showed a 4.4 out of 5 rating from 90 reviews in the last 12 months in a September 2026 snapshot. Quiet operation is among the common positive themes in those reviews, alongside strong cooling.
Treat that as a signal, not proof. Trustpilot does not verify the claims inside reviews, and Cozeware’s profile has been brand claimed since March 2026 with a paid Trustpilot subscription. A reviewer’s “quiet” is an impression, not a measurement, so read it alongside the listed dB figures above rather than relying on either one alone.
Before You Order a Bedroom Unit
Noise is only one part of the decision, and four practical details are worth checking before you order.
- Voltage: The Visio comes in 115V and 230V versions, and the 18,000 BTU model above is 230V. Confirm which circuit your room has before you choose.
- Installation: Cozeware links an installation guide, and the sponsored article says electrical and refrigerant work is still required. Whether professional installation is needed is not stated, so ask.
- Warranty: 7 years on the compressor and 5 years on parts.
- Shipping and returns: Free standard shipping, 30 day returns and a 3 to 5 day delivery estimate on the Visio 18K page.
None of these change the listed noise figures, but each one affects how smoothly the unit gets from the box to your bedroom wall.
Current Pricing and the Autumn Sale
Cozeware’s product pages show an “Autumn Sale Up to 34% Off” banner in October 2026. The homepage lists the Visio 9,000 BTU 115V at $399.99 and the E-Save 24,000 BTU at $999.99, and the sale prices for the four models above run from $526.99 to $649.99. Free shipping applies to all orders. Prices change, so check the official Cozeware page for the figure that applies on the day you order.
Summary
This guide looked at the noise levels Cozeware lists for its mini splits, which run from 28 dB on the E-Save 12,000 BTU to 36 dB on the E-Save 24,000 BTU and the Visio 18,000 BTU. It reviewed four models: the E-Save 12,000 BTU at $559.99, the Visio 12,000 BTU at $529.99, the Enduring 12,000 BTU at $526.99 and the Visio 18,000 BTU at $649.99, all shown under the Autumn Sale banner in October 2026.
The E-Save 12,000 BTU stood out with the lowest listed figure, 28 dB in sleep mode, for a room of up to 750 sq ft. The Enduring lists 31 dB in sleep mode, the Visio 12,000 BTU adds a complete installation kit with a 16.4 foot line set, and the Visio 18,000 BTU covers up to 1,250 sq ft. All four carry a 7 year compressor warranty, a 5 year parts warranty and 30 day returns.
Two steps matter most before buying. First, pick the size the room needs, then compare noise figures within that size, since the E-Save line lists higher numbers as the BTU rating rises. Second, check the room’s circuit against the 115V or 230V version, and ask Cozeware for the test conditions and outdoor unit noise, which are not published.
