Customer Questions & Answers

How does the noise level of this unit compare to other manufacturers

We plan to replace a GE Zoneline 3100 and want to reduce noise as well as improve efficiency
Asked by: Greg
Hello Greg, The LG LP123CD3B 12,000/12,200 BTU Heating and Cooling Packaged Terminal Air Conditioner has an 11.9 EER rating. National appliance standards require room air conditioners to have an energy efficiency ratio (EER) ranging from 8.0–9.8 or greater, depending on the type and capacity, and ENERGY STAR® qualified room air conditioners have even higher EER ratings. The Sound Intensity expressed as the Sound Pressure Level in decibels is rated at 50dBA which is quieter than normal conversation which is rated at 55-60dBA...IFV

What's the difference between this unit and LP123HD3B

Asked by: Chad
Hi Chad, These 2 units have the same specifications right down the line with the exception of the heating specifications where the only difference is that the LP123HD3B uses a heat pump and the LP123CD3B uses a heater(probably a ceramic heater). You can line the 2 units up on the Home Depot Site and compare them and the system will allow you highlight the similarities or differences...IFV

Does the wall sleeve and grill come with this unit?

Asked by: Michael
Hi Michael, Your interest in the LG 12,000/12,200 BTU Packaged Terminal Air Conditioner, Model # LP123CD3B is greatly appreciated. No, the wall sleeve and grille do not come with the unit. You can use an existing 42" wall sleeve regardless of manufacturer provided it is in good structural condition and that the outdoor grille securely attaches to the sleeve or flange of the sleeve to secure the new air conditioner. With a new LG sleeve, you can maintain the best performance of the new air conditioner. Keeping the old sleeve puts you run the risk of poor performance of the new air conditioner which is not covered under the LG warranty...IFV
