What is the SEER2 rating of the LBG Products LBHB24DUWO?

The LBG Products LBHB24DUWO is rated at up to 21.5 SEER2 and 12.5 EER2 for cooling and up to 11.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 7 certified matchups SEER2 ranges from 19.0-21.5.

Is the LBG Products LBHB24DUWO good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 20,000 BTU/h at 5°F with a COP of 2.30, so it is still 2.3 times as efficient as electric resistance heat at that temperature.

How much does the LBG Products LBHB24DUWO cost to run per year?

At its rated efficiency it costs about $525-$1,409 a year in electricity in large U.S. cities, depending on climate and local rates - for example $648 in Phoenix and $1,177 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Which indoor units work with the LBG Products LBHB24DUWO?

ENERGY STAR lists 7 certified combinations for this outdoor unit. The highest-rated ones use LMHB24DSI, LMHB24DZDI, LBHB24DUWI.

What refrigerant does the LBG Products LBHB24DUWO use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

A good fit if…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 20,000 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 79% of mini-splits.
You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

Cooling cost matters most - its SEER2 is below average for mini-splits.
You want the newest refrigerant - it uses R-410A, which is being phased down.
