How efficient are Trane dehumidifiers?

Of the 3 Trane dehumidifiers, 1 files a higher IEF than the class median and 2 fall below it.

Trane dehumidifiers against the median IEF (L/kWh) of their DOE class. DOE data as of 2026-11-03.
DOE class	Trane models	Above median	Class median	Best Trane
Whole home dehumidifiers (30)	3	1	IEF 2.13	4044320 IEF 2.22

A higher IEF means more water removed per kWh.

Who makes Trane dehumidifiers?

DOE's database has no manufacturer field, so the evidence is whose model number each unit is filed under and which other brands file the same unit.

Trane shares 3 units with 3 other brands. Brands it shares with, and how many units each:

How much does a Trane dehumidifier cost to run?

Running nonstop at DOE's test conditions, the 3 Trane dehumidifiers with both figures use 12.17 to 22.18 kWh a day. That's about $2.21 to $4.03 a day, or $66.28 to $120.86 for 30 days. The lowest is Trane 4044120 (52.45 pints/day, IEF 2.04) and the highest Trane 4044420 (89.08 pints/day, IEF 1.9).

Real use cycles on and off with the humidity, so these are the upper figures for a day of nonstop running.

At 18.16¢ per kWh, the US average residential price for August 2026 (EIA Electric Power Monthly, table 5.6.A). Worked out from the certified figures.

Questions about Trane

Is Trane a good dehumidifier brand?: How its 3 dehumidifiers compare on efficiency with their DOE class is above. 3 of them are the same unit as another brand's model. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
Does Trane make a 50 pint dehumidifier?: Yes, by the 2019 DOE test: 3 of its models certify 49.5 pints/day or more, led by Trane 4044420 at 89.08 pints/day. How the 2019 test changed pint ratings.
Which Trane dehumidifier is the most efficient for its size?: Trane 4044320, at IEF 2.22: higher than 18 of the 30 in its DOE class (whole home dehumidifiers). At the other end is Trane 4044420, at IEF 1.9, higher than 5 of the 30 in its class.
Is Trane the same as Broan?: For 3 units, yes: both file them under the same DOE basic model (120.1-W, 70.1-W and 98.1-W). Compare the 3 brands of 120.1-W. Compare the 3 brands of 70.1-W. Compare the 3 brands of 98.1-W.
