I found various online retailers are selling
Goodman e-Series - 12k BTU Cooling + Heating - Wall Mounted Air Conditioning System - 18.0 SEER2
for less than $400
or similar 9k, 18k btu mini split system for highly discounted price.
Goodman used to be an entry level bland for HVAC system in the USA but bought by Daikin (the largest HVAC company in Japan) about 10 years ago. Since then, the products qualities, aftermarket services are getting better?
Mini-split system is still not so poplar in the vast majorities of the USA but very poplar in the rest of the world, Asia, EU, etc. The system is similar to the typical car HVAC system that comes with 2 main parts, compress to exchange heat to cool then transfer the energy with refrigerant (used to be Freon, 134a, but now 410A) to the interior coil (indoor unit) that convert back to cool or warm air.
Depend of the system the energy efficient level are varies but there will be no combustible gas and environmental friendly. Mini split system will be the future of the most HVAC system in the US sooner or later due to it energy efficiency. In the state of CA, many cities are no longer allow to have conventional gas furnace for new homes and heat pump or mini-split are the new options for those.
Mini-split is relatively easy to install for existing houses as you don't need to run new air ducts but just skinny refrigerants pipes and wire.
Power requirements are 120v or 240v. If you select 120v unit, the initial installation cost might be less but the running costs would be higher and you will not get a powerful unit but smaller 9k or 12k or less small units only. I would recommend to go with 240v
Most people might imagine similar idea as those windows units those are noisy but not efficient to run and also high electricity bills, but mini-split system is NOT like window units.
Mini-split system is very quiet and much more efficient than windows units.
The cons for mini-slit would be
1. not so poplar in the USA (and many people don't know about it and scare it is same as window unit, - noisy, ugly, not efficient, not air-tight, high running costs)
2. the indoor unit will be visible
3. since it is not yet popular, the pro installation cost would be high
4. required special refrigerant (410A)
5. most people have negative image to mini-split system as current product line-ups are by not so well known, China or start-up brands in the USA and indeed those units might not last as good as Rheem/Goodman/Mitsubishi/LG/Samsung/Panasonic, etc.
This is just my personal opinions but I would like to avoid those eBay not so know companies TLC, costway, and I will never buy electronics from AliExpress tumi that might cause fires and also life safety without proper formal UL certificates...
the sets are online for the indoor/outdoor units but no connecting pipes and wires and other misc. items are included so you need to spend another $40 ~ 100 for that. Typical kits usually run from 16 ft to long one would be 50 ft? Depend on where you install those units.
For instance below. I was suspicious before I received the item but indeed I got the item and it is a real Goodman/Daikin product directly shipped from Daikin wearhouse in TX.

18k ebay $647
https://www.ebay.com/itm/27641052...R5bh5vniZA
but those prices are higher than I originally quoted but still good deal than the Home Depot 24k Pioneer for $1398
the best way to get line set is on ebay with wire together
but after the hurricane they jacked up price average $20 ~30 per sets.
For Goodman, 18k unit required 1/2" copper and 9k and 12k use 3/8". I think if you are not in hurry the ebay price might come down.
I need to buy one of those "50 Feet
Install Kit For Mini Split Heat Pump Systems [ebay.com] 1/4" - 3/8" Dia." but they are now asking for $100~/set vs it was less than 80 before.
planning to cut this down to half to use for 9k and 12k set.
I bought 50 Feet Install Kit For Mini Split Heat Pump Systems 1/4" - 1/2" set for 18k

Regarding 120v vs 240v
As typical outlet are 110v ~ 120v in the US, but it is not so optimized for the AC (mini-split, window AC unit, heat pump, etc) and other heavy Equipment such as cloth dryer, oven, cook top, range, etc.
For the AC (Mini-split), you should at least get a dedicated breaker - just like a refrigerator for your safety (per building codes)
It is better to run under 240v if you can. A simple example is a cloth dryer. A 120v dryer cannot be powerful as 240v dryer and it would usually take twice more times to dry same amount of cloths. Typical 120v dryer might take 2 hours or more to dry but 240v can be done with in 1 hr.
An AC unit requires more power to heat/cool a house, so it can be done slowly with 120v but it can do much better with 240v. So, 240v units are typically more energy efficient and can do the job better.
another example, Electric car charger - with 120v, it might take 4 hours to charge but with 240v, you can do in 2 hrs.
If you don't have 240v, I would highly recommend to upgrade your panel and add a new 240v outlet.
In 2025 and after, you will see many more 240v outlet as Electric cars are getting more and more popular.
Some sites are saying "PRODUCT CLOSE-OUT ALL SALES FINAL"
so you better to order now rather than later. I think above pricing are Extremely good for the reputable Goodman/Daikin products
