How many decibels is a freezer?
From 39 dBA at the quiet end to 47 dB(A) at the loud end, in the figures makers publish. Those numbers are thin.
None of the four brands states a basis: not a distance, not an ambient temperature, not a load, not a test standard. Element prints 45 dB for its 13.8, 17.0 and 21.0 cu ft uprights, three sizes of cabinet with one number, which reads as a family figure rather than a measurement. Most brands publish nothing at all. Danby, Galanz, Koolatron, Summit, Magic Chef and Arctic King showed no per-model figure, and GE confirms it does not rate them.
The ranking therefore uses the decibel figure as a tiebreaker and leans on what else is published: clearances, temperature ranges, defrost type and warranty. Four brands printing dB with no stated method is exactly the case where ratings from different makers stop being comparable.
Why is my freezer making noise?
Usually for one of three reasons, all in your control, and Hisense's use and care manual names them. In this category the manuals are far more useful than any spec table.
| Cause | What Hisense advises |
|---|
| The cabinet is not level | Place it on a level, hard surface strong enough to hold it fully loaded, and adjust the feet |
| The back is touching the wall | Leave 4 inches at each side and the top and 3 inches at the back |
| Bottles or containers have fallen or are rolling | Settle them, the cheapest fix in this guide |
Wall contact deserves a second look, because a cabinet pressed to drywall couples compressor vibration into the wall. Check all three before calling for service.
Mind the rollers, too. They are not castors, Hisense warns, and should only move the freezer forward and backward, since pushing it sideways can damage the floor and the rollers.
Five sounds Hisense calls normal
Three of them are the ones people mistake for faults. The manual's list:
- compressor running noises
- air movement from the fan
- a gurgling sound, like water boiling
- a popping noise during automatic defrosting
- a clicking noise before the compressor starts
A manual defrost chest freezer never makes the defrost popping sound, one practical reason a chest can seem quieter in a quiet room.
The same manual gives a separate list for a compressor that seems to run constantly: the temperature set colder than necessary, a large quantity of warm food put in recently, a hot room, or a door opened too often.
Garage ready means what each maker says it means
Read the temperature range rather than the badge.
| Maker | What its garage claim covers |
|---|
| Hisense | Rated 0 to 110°F, but garage ready "only for freezer mode"; fridge mode needs 55°F or warmer |
| GE | Its 2018 and newer freezers work from 0 to 110°F |
| Danby | The same 0 to 110°F range, with a garage defined as enclosed, so the freezer is not exposed to rain or snow |
| Element | "Garage Ready Yes" on its upright spec sheets, with no ambient range |
Element's label alone says nothing about a winter garage. ENERGY STAR pulls the other way entirely: unless you live in a mild climate, keep the freezer indoors, because extreme temperatures are hard on the compressor.
If yours is going downstairs, our page on keeping a quiet basement covers where to put it among the other machines there, and how their vibration reaches the rooms above.
Is a chest freezer quieter than an upright?
Neither type can be called quieter from these sheets. The uprights print dBA, dB(A) or plain dB, the chests plain dB or dB(A), and not one states a basis.
Running costs are clearer. ENERGY STAR puts a certified chest freezer at about 215 kWh a year and an upright at about 395 kWh, because a chest's lid opens from the top and lets less cold air escape. It also notes that manual defrost models use half the energy of automatic ones, provided you defrost before frost passes a quarter of an inch. Against that, an upright is easier to organise and takes less floor space, and the noise figures do not settle it either way.
More chest models with a maker figure are on the chest freezer page. For an upright, our guide to the quietest upright freezers turned up a figure from a maker with none here: Summit lists 32.4 dB for its UF22W, which it rates as a freezer from 0°F to 110°F.
The sealed system term is the one to read
A compressor failure is the expensive repair, so the sealed system term counts for more than the headline year.
Hisense chest freezers are the only ones here with a separate sealed system term, five years parts and labor.
| Brand | Warranty |
|---|
| Hisense chest freezers | One year parts and labor, plus five years parts and labor on the sealed system |
| Element | One year, or two if you register within 90 days; no separate sealed system term |
| Midea | Two years limited, with no breakdown published |
| Kismile | One year, with a paid extension offered |
Five ways to end up with a louder freezer
Most brands publish none, and GE says it does not rate them.
Trusting a repeated number
Element's 45 dB covers three different upright cabinets.
Reading "garage ready" as a promise
Check the temperature range and the mode it covers. Hisense's 0°F rating holds in freezer mode only.
Pushing the freezer against the wall
Hisense asks for 3 inches at the back and names wall contact as a noise cause.
Ignoring the sealed system term
One brand here covers it for five years; the rest do not break it out.
