With the changes over the years on freon for air conditioners and the required upgrade to new systems, and now the supply chain shortages for parts and for new ac systems altogether, has anyone started using mini split systems? I believe the info I gathered a couple of years ago showed the mini-splits are a lot less expensive. What are your pros and cons (if you have switched to mini-splits)? Any other ideas or new technologies around the corner?

The advantage of a high efficiency split heat pump is used all year round along with SEER of 23 is going to use less energy. Expect system to last 10 years where check warranties on compressor as most expensive part. Like any HVAC system a well insulated building with a steel roof light colour will keep building cooler along having a ridge vent on top where heat is exhausted. The new norm is triple plated low E windows which limited heat transfer all year round. Another advantage of a high efficiency split pump is less noise as the compressor is outside along with modulates which means the compressor will working constantly maybe 30 per cent which means no on and off operation. The disadvantages is more costly to buy and install along with some units requires 208-240 VAC voltage with higher current depending upon unit selected. Renting out anything which sets rental home or rental unit from competition is energy costs as the cost of a energy efficient system has to amortized into rent to pay of the system. Spray foam in the ceiling along vents in the rafters will keep heat out and heat in all year round. Windows units are cheap not very energy efficient along most can not used for heating. Also very noisy as the compressor is in the same housing. View some different videos on You Tube about high efficiency heat pumps then get more information. No one knows what energy costs are going to be the next five years. --68.69.xxx.xxx

As a test, I installed a mini split in my home a few weeks ago. I am loving it. Quite and cold. I want to put more , but the wife objects, due to the size of the air handler on the wall. I canít say I donít agree, thatís it is an eyesore. But I can do mini splits for 700 each, 3 will do a house, while a complete new split system will cost me $4500 --66.169.xxx.xxx

What about noise outside for neighbors??

Are there any restrictions, laws that govern how much noise can be made on the noisy portion on side of wall next to other apartment building??

I would really hate to install and find out I am in violation of some noise ordinance and have to remove them or get sued.

I got a quote for 4 Mitsubishi 16 SEER 9k Btu Wall Mount Mini Splits for a 600 sf duplex (long, skinny units). 2 per side, heating + cooling. (1 br, 1 lr, x 2.) The price came back as $11,100 installed. ($2775 ea) At that price--- no thank you.

Dino, the one I installed, the outside condenser is much quieter than a traditional split system condenser. In fact, i can hardly hear it running at 10 feet, I have to look at the grass to see if any grass blades are movingÖ.. now the condenser next door, I can hear that thing at 100 feet. --66.169.xxx.xxx

I just had an LG mini splint put in a 750 sq ft duplex. $2600. The head unit is in the living room and there are ceiling fans in the 2 bedrooms and living room. I am hoping it is enough but too early to tell. The other option was $7500 for heat pump with ducts in crawl space. The unit previous had resistive ceiling heat and window units. That is not the look I am going for. --65.188.xxx.xxx

For our own home on Cape Cod we had installed solar panels. We added a mini-split for the large converted/insulated porch. We loved it.

We sold the home and the new owners put in many more mini-splits, as they essentially run for free.

You can get ceiling vents instead of the big wall units, but I've not tried them. --98.250.xxx.xx

We just bought an Amana Through-Window Heat Pump/AC unit (which we install through-wall instead and frame it out nicely. They come in a chassis so you can slide the unit out separately for repair/replacement.) Not a PTAC - this is a window-unit size.

$869.00 today for an 11k unit from AJ Madison online. We first bought this same unit back in 2015 - it was $615 back then (I just looked.) This will be our 20th unit in which we have installed these since.

They last as long as 10 years, but at least 6 or so.

Repair is usually not worth it. Hard to find someone.

We have ONE mini-split out there. Amazingly quiet, amazingly efficient for the tenant but it cost us a BUNDLE to install. No thanks. We'll stick with our solution. --50.82.xxx.xxx

I had minisplits installed in a duplex where the gas boiler went kaput. Tenants love them. I have the hyperheat models. Cost me 15000 and I have 7 heads between the two units. That was the cost pre-pandemic. Gotta think its more now. --209.122.xx.xxx

I got one for my home. Lasted ten years. Got a Misubishi 18000 and it cost me 6 K from the high priced hvac in Princeton. Since there is a plug for a 220 window unit I have a spare. I used the window unit last year and this year and the minisplit is sitting. It makes mold grow on my antique furniture. The instructions say to only run it for four hours at a time. Well, the window unit has been running for a couple days with no down time. I have a mini at one of the rentals where the upstairs needs an AC boost to the central air unit in the basement. That works very well also.

Is it better to just keep running the window unit until it gets cool again or should I shut it off for a couple hours here and there? REally impossibly warm here. --108.24.xx.xx

Although the house does not have AC. Going to consider installing a high efficiency split heat pumps in bedrooms which can be used for heat and cooling. So far some days were very hot as one day the high was 34 degrees Celsius or 93 F. The focus is going to reduce heat gain and heat loss in the house where going to continue with A DIY two can spare foam kit remove the garbage useless fibreglass insulation then spray foam ceilings then install rafter vents in the rafters then add additional insulation to the rafters. There is a ridge vent on the top of metal roof where will try to keep the attic the same temperature all year round which is going to load on the HVAC system. Less time on longer life. Tonight after finally receiving rain it is cooled off in house where using ceiling fan in bedrooms. July as been a extremely dry month where the grass did not even grow. Global warming is a reality here where in the past never in some areas of the country temperatures where reached 40 degrees Celsius. There are two factors when installing a HVAC system which are the load and capacity of the HVAC system where if the load is reduced then the system can be downsized along with the system will last longer. Soon triple plated low e windows are going to become available. --68.69.xxx.xxx

I read my Costco flyer every 2 weeks or so. They had a sale plus a $60 manufactures rebate, per unit.

A Midea 12,000 BTU Cooling Inverter Window Air Conditioner

Item #1575342. Marked down from around $399 to $339, then a $60 manufactures bonus discount with a limit of 2. So it came to $279.99 plus tax, free shipping.

With California taxes, each unit came to $306.59.

I was able to buy 4 of them at that price. --47.156.xx.xx

Robert,

Is the 12,000 BTU inverter you got at Costco quiet enough so that an apartment building next door to that wall it is installed on will not cause complaints from neighbors??

Also does it require 220V and if so what can you advise about what I would need to do to add a 220V line to the units in that building?? I have never needed to have an electrician do that before.

This 12,000 BTU a/c-Heater is quiet using the standard 120 volts. It is NOT silent though. Around 1/2 the noise of any older 12,000 BTU unit. That sale is over and Costco promotes another unit that is only cooling. But you may be able to special order one. Buy one and test it.

Robert,

What is your view on installing window unit in wall instead?? I would need to create through-the-wall installation from beginning as there has never been any wall opening before.

I know it is more work but then I would not be creating obstacle to using window as normal in the bedroom and it is only window in bedroom so I would want to be sure that it would not violate any requirements regarding egress by placing a window AC in the bedroom.

I do this two ways. Under the window where there is already a header to support the load over the window.

Way two, remove the window and install a shorter window and then the a/c unit below. So if you had a 36" wide x 48" high window, I' remove the window and replace it with a 36" W x 28"-30" window installing the air below it.

And if the a/c goes thru the wall, I'd a a removeable case so if the a/c fails, I can slide it out and install a new a/c into the sleeve. --47.156.xx.xx

Thanks Robert for good info.

The bedroom has horizontal sliding windows which are approx 48" x 48". Since it is horizontal slider, only half of width is actually available as the space to fit window AC.

Glad I asked since I just assumed I would create a new opening to the side of the window near the electrical outlet but under sounds good assuming there is room. I will check it out.

On the issue of the electrical outlet, I know you mentioned above that you can get these units in 120V. Is that unusual or will there be a good selection that use 120V.

Lastly, can any window AC be modified to fit in wall install or will it require specific model designed for wall install??

Trouble with UNDER a window is furniture placement and efficiency. COOL air drops...We HAVE them under windows where there is nowhere else, but our preferred place is in-wall.

We cut a hole at about eye level or so on an appropriate wall and frame it out. The unit is more efficient that way - disperses cool air better - and doesn't interfere with furniture placement. --50.82.xxx.xxx

I recently installed a Mr Cool mini split DIY 12K BTU on the 1st floor of one of my rental townhouses. Only required a 110 outside electric line, which my electrician completed for a few hundred dollars. Freon is already loaded into the Mr Cool compressor unit when it is purchased so it is truly a DIY install. For $1600, there is one interior register and it cools 500 sq foot area. (Mr Cool does sell larger capacity units and with addl interior registers). It is whisper quiet, inside and out. Took about a day to install. I am over the moon happy with this purchase. I'll install the same unit in the other three townhouses once the existing tenants leave.

I chose the Mr Cool option when a trusted HVAC guy quoted me $35,000 - 40,000 to run 4 Mitsubishi mini split units into my 4 townhouse units (side by side) with 2 interior registers per unit - one on the 1st floor and one in master bedroom. Just could not justify the price.
