$600 SEER 15 or $1,000 SEER 23
 

Window units need to go. They are too small, don't cool well enough and are a security hazard as I live in the hood.
The window unit is an on/off 6,000BTU unit. It barely cools the bedroom on hot days.
I am going to get a split unit. I am leaning towards getting the more expensive 240v powered $1,000 inverter unit.
Best I can figure if I only used the more expensive air conditioner during the summer it would pay for its self in 2 years as compared to buying the $400 cheaper unit. Using the heat pump for heating during the winter, even better it may pay for its self in one year.

I would go for the higher SEER.

Whats the energy savings between a 23 versus 27 SEER?
9,000btu would work.

It is only $15 a year savings. But the 27SEER unit has more options like quite mode when you sleep.
More fan options 1 degree temp chang.

I like the sound of quiet mode since it will be in the bed room where my wife who works night shift sleeps during the day.

My boy uses the quite mode at night. I also have the same unit in my bedroom and I never use it.
The low setting is pretty quiet. We don’t hear it at night. My room gets hit with direct sun all day and badly in the afternoon. I will turn mine up in the afternoon but by 6:00 I can turn it back to auto. This is just when we have these 95-100 degree days. My boys both leave them on auto fan all day.

The LG mini splits in the living room cool really well but the temp adjust 2 degrees at a time.
one setting is a little to warm the other setting is a little cool. (not as bad as forced air system)
The Gree I have adjust one degree at a time it is much simpler to get the exact temp you want.

Higher SEER usually are the inverter driven ones, and are quieter.

Buy a dozen or so 20 mm 120V MOVs from Mouser or other supplier and put in your disconnect box and at your breaker. Before I did that, son's Klimaire inverter unit reset every few months due to power line transients where he is.
reset = shutdown and required breaker cycling to reset automatic latch off.

Tell us more specifics for these MOVs. 120V and not 240V? Does one go on each 120V circuit?

Thanks,

Steve

I installed my first Gree mini split 10/18/2013 and LG unit right after that have not reset them once. Maybe my power is different I am the last house on a very long utility line.

Since I have solar the voltage would stray more than people that don’t have solar at lease during the day.

Yeah I keep 130v rms AC on hand and stick them in side stuff as I build and modify. I use them to protect electronics, such as when I built my entertainment stand I put them in the built in electrical distribution system, or to protect power factor correction capacitors in welding machines and air compressors.

What I do with 240 volt machines (welders, air compressors and plasma cutter) is wire a 130v MOV from each line to ground.
