What is the SEER2 rating of the LBG Products LUUHB48DO?

The LBG Products LUUHB48DO is rated at up to 17.0 SEER2 and 8.2 EER2 for cooling and up to 10.7 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 4 certified matchups SEER2 ranges from 16.8-17.0.

Is the LBG Products LUUHB48DO good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 49,000 BTU/h at 5°F with a COP of 1.98, so it is still 2.0 times as efficient as electric resistance heat at that temperature.

How much does the LBG Products LUUHB48DO cost to run per year?

At its rated efficiency it costs about $1,307-$3,209 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,584 in Phoenix and $2,647 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 LUUHB48DO?

ENERGY STAR lists 4 certified combinations for this outdoor unit. The highest-rated ones use LUHB48DZDI, LUHB48DSI.

What refrigerant does the LBG Products LUUHB48DO 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 49,000 BTU/h at 5°F.
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.
