In a few days, months or years it will break (because it wasn't made to last) and if you think you have '10 year warrany' - think twice! The warranty is PARTS ONLY! So, you'll have to hire a tech to diagnose it (~$200) then they'll send you a replacement part (AT YOUR EXPENSE!) and then you have to hire a tech again, and he'll evacuate the refrigerant, do the repairs, vacuum purge the unit and recharge it (with all 'bells and whistles' that will cost you AT LEAST another $600 - $800). So, you'll get a $50 or $100 part 'for free', and you'll have to pay out of your pocket over $1000 - half of the price of the unit or more, and there'n no promise that something won't break again in a week and you'll have to pay all over! So, better burn your money - at least you won't feel bad about a lousy heat pump manufacturer laughing all the way to the bank with your money. Also, I found that their website is quite interesting in terms of posting reviews. All the reviews there a boasting about 'quality', 'out of this world warranty' and 'overwhelming number of 'happy customers'. There's one problem - YOU can't post your review there! So, I wouldn't be surprised if these reviews are fake or 'carefully selected' to fool people.
