What the Best Split level AC Units...Carrier LG, Panasonic?

How effective would this paint be at reducing temperature vs the normal radiant barrier under the roof?

was wondering this myself

[gastly369]

Installed a gree inverter smart unit last week... Replaced a 15 year old panasonic

What size and price?
You had to buy the wifi module separately?

12k btu $3570 without installation as my good friend who does installs just took the panasonic unit for the installation fee

Came with the wifi unit etc
Servair gree dealer( installation fee is $1200) from them....

Advise installer to be knowledgeable with inverter installs using micron gauge etc

Does paying the extra for inverters make sense with the price of our electricity? In the past when I calculated it you wouldn't see the savings for the life of the unit.

[paid_influencer]

it is plenty quieter tho

[Chimera]

Idk I find the sound of a ac never bother me. Is just something that was always a background sound over the years so paying double for a quieter unit never make sense. When both of them gonna last the same amount of time and you would never realize the savings from buying a inverter with our present subsidized electricity prices

Depends on the unit. I know someone saw a $1500.00 reduction in electricty bill after replacing a 3 tonne. He swapped out the 5 tonne after, not sure how much the bill went down by after that.

esp as you go larger the price differential gets bigger, but that is the way things are headed in general worldwide
all big motorized machinery utilizing speed controllers for efficiency rather than hard stop/starts

I figure money spent on attic/ceiling venting would be more worthwhile.
if you drop your ceiling temp 2-3 degrees, the load on the ac will be dramatically less.

Cleaning your roof will improve reflectance and help to cool it also.

[Chimera]

Well that's what I studying.

I have a 18000 in my living room and it under pressure these days.

I was gonna buy a 24000 that wud cost like 4600 installer....and put that 18000 in a smaller guest room......

But I studying to spend that 4600 on painting the roof with the reflective shiznit

[Chimera]

But I getting my extractor fan this week too so if I using extractor fans that will expel the hot air....do I need to paint the roof lol

[pugboy]

get an infrared gun thermometer and check the indoor ceiling temps at diff times of the day and night before you install the extractor fans to make a good judgement if they working

Y'all forgetting heat radiation from the walls.

[pugboy]

yeah but that hard to fix unless you putting trees and awnings to block sun on walls or extra layer of cladding or something

a concrete wall could hold heat whole night

[VexXx Dogg]

imagine paying extra for a unit that supposed to last longer and use less electricity and numbskull AC technicians firetruck it up.

Got a Samsung Windfree Inverter 9K BTU installed for my bedroom. Had to get it because El Niño is causing days of 33-5 degree temperatures during winter. I thought the AC guy was mad to suggest a 9K for my bedroom, as the smallest I've ever had was a 12K Lennox. I can't go back to regular ACs after this. This thing works better than all other AC units I've ever had, even ones with much higher BTU ratings, it's whisper quiet, cools down the room quickly and doesn't guzzle power. No cold drafts around the room either. Plus you can control everything from your phone remotely. I can turn it on before I get back home to cool the room. I would have never considered a Samsung before but the price was hard to beat here. Everything was installed for around 2600 TTD.

Sorry Duane, I live abroad in Brazil, I was converting the local currency to TTD. I don't think Samsungs are anywhere near that cheap in Trinidad. They're a good value for what I paid, but when people would charge you 6000 TTD for that same thing, then it might make less financial sense.

Most white acrylic paints have a better SRI than tinted solar reflective paints. If your walls are warm to the touch, paint them white.

IIRC, though not as good as white, light grey and light tan, have good SRI values, also.

Yeah I thought it sounded too good lol
thanks though

Easy fix for all these issues. Build a roof to cover your existing roof, make it wide enough to cover the house walls too

Anyone have experience owning. Pioneer inverter 12000 btu mini split?

that going to go up soon tho, so it will make sense

Surrounding greenery keeps temps down, just saying. Done right, it can be easy on the eyes and provide shade.

Lower the ambient temps, better heat rejection by AC units and the more efficient they operate. Less work for them to do as well.

Those with commercial units that have the metering device inside the evaporator can run a copper coil into a condensate pan where cold condensate water cools the refrigerant making the process more efficient.

Who have repairs to do can remove and bypass the capillary tube in the condenser and braze on an orifice type metering device further up the small line with similar setup to increase efficiency.

Only if it doubles

[supercharged turbo]

Any recommendations where I can get a portable a/c unit for a room?

[pugboy]

just remember you need outlet for the exhaust hose

[supercharged turbo]

I know

[maj. tom]

Portable units are stupidly inefficient and poor design. The evaporative cooling and heat exchange system and the area to be cooled are all in the same place thermodynamically.

Either get a split unit or one of those window units where at least the coils are outside the room to be cooled.

[pugboy]

some are actual condensing type and not evaporative water fans
they work soso but I suspect very inefficient

if place is sealed up, a dehumidifier helps a little too.
