so we just built a brand new house and kitted it out with a 14KW fujitsu ducted heatpump and its nice and quiet...but the neighbors one ( not a brand i usually equate to heatpumps , i think its a samsung?/) sounds like a cessena buzzing around our house (and theirs is only a 7KW one).
any thoughts on how i can broach this with the said neighbor without ending up on TV? its SERIOUSLY annoying and resonates throughout our living area. He's a total tightwad cheapskate so dunno how this will play out....
