Hisense vs LG window air conditioners

Both lineups side by side at every size both brands sell, from the 23 new window air conditioners we can find in stock right now: live prices, CEER ratings, noise and the warranty each listing states.

The short answer

We track 6 Hisense and 17 LG window air conditioners in stock, and both brands sell 4 sizes in common (8,000, 10,000, 12,000 and 14,000 BTU).

  • LG's cheapest model costs less at 3 of the 4 sizes; Hisense's costs less at 1.
  • Where both publish a CEER rating at the same size (1 size), their best models are within 0.5 of each other.
  • LG has 3 inverter models in stock, and no Hisense model in stock states an inverter compressor; an inverter compressor slows down instead of switching on and off, which is usually quieter and more efficient.
  • Hisense's listings state 2 years of compressor coverage against 1 year for LG's.

The better buy depends on your size, so compare the models at yours below.

How we compare two brands

  • Only new units we can find in stock with a live price, at the same size. A brand's average says more about its size mix than about the brand.
  • A price difference counts when it is at least 5% and at least $20, and only between models that install the same way (a do-it-yourself kit is never priced against an installer-fitted system).
  • Efficiency is compared on one scale (CEER) and counts at a gap of 0.5 or more; noise counts at 3 dB(A) or more, using only ratings checked against the retailer's specification for the exact model.
  • Warranty terms are as each listing states them. Models named in a CPSC recall are never compared or sold here.

Hisense vs LG: common questions

Is Hisense or LG cheaper?
It depends on the size. Comparing each brand's cheapest new, in-stock model at the same size, LG's cheapest model costs less at 8,000 BTU ($269 against $409), 10,000 BTU ($329.95 against $449) and 12,000 BTU ($459 against $529) and Hisense's at 14,000 BTU ($549 against $579). These are live retailer prices and change often.
Which is more energy efficient, Hisense or LG window air conditioners?
Comparing the best CEER rating each brand publishes for its in-stock models at the same size, their best ratings are within 0.5 at 1 size. A higher CEER means less electricity for the same cooling. Not every listing publishes a rating, so a size with a rating on one side only is not compared.
What sizes do Hisense and LG window air conditioners come in?
In stock right now, Hisense sells 8,000, 10,000, 12,000 and 14,000 BTU and LG sells 5,000, 6,000, 8,000, 10,000, 12,000, 14,000 and 18,000 BTU. So only LG sells 5,000, 6,000 and 18,000 BTU. Size the unit to the room first: an oversized unit short-cycles and leaves the air cool but damp.
Do Hisense and LG make inverter window air conditioners?
No Hisense model in stock states an inverter compressor, and LG has 3, going by each listing and the maker's model numbers. An inverter compressor slows down instead of switching on and off, which is usually quieter and more efficient at part load.
Which has the longer warranty, Hisense or LG?
As the retailer listings state it, in-stock Hisense models cover the compressor for 2 years (5 of 6 listings state a term) and LG models for 1 year (17 of 17). Where a listing names no separate compressor term, its general or parts term is what covers the compressor. Some terms require registering the unit, and a maker can require professional installation to honor its warranty, so read the warranty document before you buy.
Have any Hisense or LG window air conditioners been recalled?
None of the 6 Hisense and 26 LG window air conditioners we track is named in a CPSC recall notice we check. That covers the models listed here, not every model either brand has sold, and it is not a safety certification.
