Choose Slightly Higher HSPF or save $ upfront as payoff is ~7 years.
I’m looking to buy a mini-split for my business office. Seems simple enough but I have 3 basic choices.
15 SEER 9 HSPF at base price for either 115v/230v, simple inverter
21.5 SEER 9.8 HSPF(IV) bp+$300 for 230v, upgraded inverter
21.5 SEER 11.2 HSPF(IV) bp+$320 for 115v, upgraded inverter
I’ve no problem installing 230v vs 115v and it’s only 5′ from the panel.
First, is it even worth paying the $300+ for about a $40/year savings? 9 vs 9.8 or 11.2,
Second, if so is the higher HSPF worth the ‘energy hit’ of 115v (11.2) vs 230v (9.8) for the presumed higher HSPF when we’re actually in Area 1(Seattle WA) vs the units’ tested area IV?
In many ways this is nitpicking. But, I’m self installing (with line evacuation help) and the unit will be an example to clients. So having an educated opinion on these things will help me explain it to my clients.
Thanks so much for your input.
