Luxaire LX Heat Pump Reviews


1.0 rating
Very Unsatisfied

We bought a Luxaire seven years ago, and it's been one problem after another. Every year since we've had it major repairs have been necessary. To name a few, a new defroster, new coil, new compressor, and a call is in today for another problem. Not a good investment.

In this day and age of trying to keep your utility bills low, I have found that this heat pump has far exceeded my expectations. I would recommend this type of equipment to anyone wanting to keep their bills lower each month.

"Noise & icing problems, Luxaire does not answer emails"

3.0 rating

Heat pump works mostly OK, but when first used in heating mode the high refrigerant pressure caused a loud rattling compressor noise to be transmitted via the coolant pipes to the house and attic unit. The contractor reduced pressure and the noise was eliminated, but I wonder if the reduced pressure may now be contributing to the outside unit icing over in wet cold weather. Either that or the automatic self-defrost does not work right. Also, I'm wondering if the reduced pressure lowered the cooling efficiency, as it seems to run a longer time to lower room temperature. Multiple attempts were made to contact both Luxaire and Johnson Controls via their web contact forms, but no response was ever received. I could not even get verification that the warranty registration had been received.

"NE Ohio heat pump"

5.0 rating
Very Satisfied

I bought a Luxaire LHJF model 3-ton heat pump. It is 14.5 seer. I matched it with the Luxaire 3.5 ton coil. I had the txv valve installed in the field on the coil. It works great. I'm in a Northern climate (Cleveland, Ohio). I can heat my house with this thing down to 15 degrees. I run my gas furnace as backup when it is snowing to avoid defrosting a lot and when it's below 25. I tested on very cold days to see what the heat pump can do. It's also cheap to run. You can run this thing a lot and it will only add like $50 to $75 to your electric bill. Nice to have with the gas furnace as backup. No problems so far. Only had it installed since October 2009 but used a lot already. I did have some loud noise off it, but I tightened some screws and this vibration and noise stopped. Overall, the unit is very quiet. This model has a jacket around the compressor. Overall, it's a great value.

Other LX Reviews

There are very few online comments regarding the LX on HVAC forums. There is a post on asking for comparisons of the LX and a similar Trane unit. Opinions seem to be that the Trane is slightly better, but both are good units. Another post on the same site is from a homeowner asking for opinions of the LX. Most comments are positive, with several saying that it is the same unit as a York.
