$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.

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

23 SEER unit
Gree VIREO 9,000 BTU Ductless Mini Split Air Conditioner w/ Inverter, Heat Pump, Remote & 50' Lineset (115V) - Single Zone Systems - Ductless Mini Split Systems - Heating & Cooling

103 Estimated Annual Cooling Cost

27 SEER unit
GREE Terra 9,000 BTU Wall Mounted Ductless Mini Split Heat Pump System R410A 208-230 VAC - Single Zone Systems - Ductless Mini Split Systems - Heating & Cooling

88 Estimated Annual Cooling Cost

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.

pinballlooking 07-27-16 11:30 PM

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.
