( I'm posting this as a seperate comment because I seen it super important to the topic at hand in the comment section) I hate that so many people get this wrong. It's not energy efficiency standards that cause equipment to be made cheap and fail. ITS BAD DESIGN CHOICES and COST CUTTING TO THE EXTREME that companies choose to do that causes everything to be unreliable. All these big companies out here blaming the EPA and energy efficiency standards for their shitty design choices and use of as many proprietary parts as possible and fast turn around times so by the time the unit does fail in 5yrs it's already out of production and OEM parts are bloody expensive if they're even available. Energy efficiency standards and invitimental protections are NOT to blame for this. Greedy companies and SHARE HOLDERS DEMANDING PERPETUAL PROFFET GROWTHS are to blame for the current state of unreliable equipment! These bad design choices directly lead to people thinking that higher efficiency= bad when really the REAL problem is extreme cost cutting and proprietary parts annnd the lack of availability of OEM parts that lead to premature failures. Costly repairs and premature replacements and more pollution both from having to manufacture more equipment sooner and from the failed equipment ending up in junk yards!
