Sorry of this is a dumb question. Don't want to lose my AC again, though
Should I buy a new air conditioner prior to 2025 propane mandate in denver
I have 5 Midea CS445UI-18C(AG)(C) AC units.
4 of them work like intended. The 5th one, I turn it on, it shows the temperature I set it to and then it starts showing the indoor temperature of the room, the other 4 just show what I set it to. I tried looking in the manual but they don’t even mention that this is possible. The person who installed them didn’t connect them to the WIFI so I did, the app works with all 5 but even there there’s no option for this.
Any ideas of what’s happening?
Thank you in advance!
Hi guys wanted to get comments if this will work as a box to house a window air conditioning unit by hanging this box in my enclosed balcony awning and positioning my intake / outlet air duct through the gap of my roof eaves?
Will get a carpenter to make the box and hang it using angle bars…. Should probably line it with some rock wool to for insulation.
Will it produce less cold air or somehow vreak the unit? or am I able to get away with this setup without compromising my aircon?
Installed Emporia energy monitor and noticed when the AC unit turned on it showed both circuits pulling power for a total of 4.5 kWh. I have a 3 ton unit Does this seem right?
I hired them to do 1 ac replacement plus furnace. They poured the slab this size. I thought it was a small square slab but they said a rectangle this size would fit 2 ac units. Now it doesn't. They said when I replace the smaller unit, I can pour an extra concrete slab. I am ocd and this is very infuriating to me. What the heck am I supposed to do now?
We're in Florida and our recently purchased home has an approx 300sq ft Florida room(aluminum enclosed patio/sunroom w/insulated aluminum roof). The room has as 8000 BTU window unit installed thru the wall up near the top of the ceiling on East side of room. It work but doesn't get cooler than 85 during the day in summer. At night when outside temp is below 80 it does a fairly good job. I'd like to replace it with another window ac but am not sure what size to go with. It faces south and there's no shade so the sun beats from sunrise until 4pm. We have grandkids who love to play out there but it's just too darn hot out there during the day making it useless until after dark.
I'm not sure if this is the appropriate sub to ask in, but can somebody please recommend a ducted reverse-cycle air conditioner (i.e., electricity-powered whole-house refrigerative air conditioner that also provides heating) that has good air purification technology? Ideally, I would like a unit that also allows me to control humidity (not just removing it when cooling, but maintaining a constant set humidity). I'm in Australia if that makes any difference. The lowest temperature ever recorded in my town is -5 °C (23 °F) and the highest temperature ever recorded is 51 °C (124 °F). Summers typically have a week or two above 45 °C (113 °F). The house is single story 160 sq m (1720 sq ft).
From what I've read, HEPA filters aren't yet a thing on ducted air conditioners due to rate of air flow. I understand there are some air conditioning units that provide ionizing filters though. I've been told that humidity control "isn't available except on commercial units" by one installation company and is "no problem" by another (not sure I trust either). The one quote I've received so far is for a Daikin Premium Inverter (FDYA140AV1 / RZAS140C2V1) that doesn't have filtration (excepting dust filter) of humidity control. The brands that companies in this area seem to primarily use are Daikin, Actron, and Samsung.
I can’t figure it out, do you guys know what I’m talking about? This isn’t an issue, I love the smell, it’s extremely nostalgic for some reason.
I need to have my Daikin 10kw reverse cycle cassette split system replaced. I'm able to reuse all of the interconnecting cabels and pipe work etc. As well as disconnection and disposal of the old unit. What sort of a fair price should I be looking at? TIA I'm in Australia.
Is this normal? It just sounds like rain or ocean waves. It also blows air in sections, like puffing and not fully like a continuous flow.
This is newly installed really recently and was mistakenly used at full blast in like its 2nd day used. Did i make a mistake?

In preparation for renovation to the exterior facade of my apartment building, workers have covered the outer part of my window air conditioner with a foam pad, presumably to protect the unit and to prevent any dust or asbestos entering my apartment.
Today it’s roasting hot in my apartment, and I’d really like to turn on the a/c. Would it be safe to do so with the foam pad covering the exterior of the unit?
anyone know how to fix it? its a lg ac, window type
also to add the ch 05 also popped up the other day and yesterday but it eventually the ac was working again.
I want to utilise a through wall aircon to be mounted indoors. 1 It's a smallish, 33 square M room. 2. Noise is not an issue 3. There is a drain for the drain 4 I have wall mounts
But, I need to find a shroud for the outdoor end to attach and ventilate through an air duct. Your thoughts?
Hello! I recently bought an TCL AC unit (TAC-12CHSD/XA73IFF) and got it installed today. It works fine and all, but the pairing process i would guess doesn't even start so I'm not able to connect it to my phone. I made sure that my phone is connected to my wifi at 2.4GHz, it has its bluetooth and location turned on but i still can't get it to work. On the TCL home application on android there are steps to complete to turn on the pairing process but after i complete them (press and hold the up button and mode button for 3 sec, after which press and hold the eco/display button 6 times), the AC just beeps twice and does not show the "CF" thingy. I opened the front panel to see if there is some kind of a wifi usb dongle but i didn't find anything. i checked online to see if my model has wifi and it does it even says it on the box so i have no idea where the problem comes from. I would be very thankful if someone could help me out :)
I’m trying to “freeze” my room so to say at least keeping it below 60 degrees. I see most window AC units only have a setting for 64, is there any AC units that go below this?
Additional context, getting a thermostat, and outside temperature is around 59-70 degrees depending on the night. Thanks lads!
If I can turn my room into a meat locker even better!
After 6 months of owning this, I have suddenly stopped getting cool air. I have tried all the LG recommendations but l believe it is the compressor that is not working. It engages but it is not as loud as it used to be and I do not get cold air. Is it worth hiring a 3rd party to fix it? Should I just toss it and get a new one? It was $399 so l would hate to throw it away after only 6 months.
Are any of the Amazon foams/sprays decent at helping to clean salt air corrosion, grime build up, and just poorly maintained condenser fins on split aircon units in the tropics?
Hello
So I have this AC Mitsubishi Heavy SRK35ZS, that I can't connect to the m-air app (that's the one mentioned in the official manuel)
It states that you need to press a combination of keys , it should beep and wifi should appear, but it does not . I get the Ln On mode and beep but still nothing, there was option for SL and E1 mode, it beeps again and nothing appears.
It's my first time connecting and I simply cannot any tips?
What would cause the TXV to repeatedly go out? We got a new unit 8/2020. We had the 4th TXV replaced August 12, 2024. The inside coil froze 10 days ago. I clean the coil and it was fine. Then 4 days ago it froze again. I climbed under the coil and REALLY cleaned it. Within 8hrs it was frozen again. That’s when I figured it was low on freon. Called the AC company back out. It was low on freon and they replaced the straightener valve. But then “the numbers weren’t right”. After messing with it, the tech says “I think I need to replace the TXV again” I said, why do they keep going out. This is the 5th one in 4 years. Hell, the last one didn’t even last 2 months. The tech said “I’m trying to figure out why it would keep going out too. Maybe I can put a bigger TXV in”. Any ideas?
We live near Dallas, TX if that helps
Hi all,
I had this Aircon installed it comes with a handy purifier option. Is it wise to run always this purifier feature while operating the system?
As far as I understand the purifier is a ioniser one, which I believe that might produce ozone, but I can not found any information on mitsubishi wether or not this feature can be turned on always and call it a day
Can someone shed some light into this?
Thanks!
Just noticed this today. Could anyone please tell me what is this?
Hello,
I just moved into a home that uses a Trane tem4a0b30s31sa model AC unit. I’m having a hard time figuring out what size filter to purchase. Please help!
I measured the unit and I think it may be 18.5x21x1, however this doesn’t seem to be a common size so I’m having some doubts.
Thank you!
I have a property in Costa Rica (new build in 2023) with four Carrier mini split AC indoor units, served by 2 outdoor units.. When down there in March, I had the installer equip 2 of the 4 indoor units with the Carrier branded US-OSK105 WiFi Smart Kit (see pic below/attached for my actual smart kit). I have since decided to do the other 2 and was planning to source 2 more of these Wi-Fi kits here in Canada before heading down again. I have called both Carrier Canada / North America and as well a number of local dealers. Carrier won't provide any info at all, and simply refers me to talk to local authorized dealers. In talking to local dealers they do not seem willing to help, citing either that they do not sell parts (this is more of an accessory item in my view) or that they only will supply this if they come out and install it, and some won't even entertain that, unless they are the original supplier & installer of the system.
In searching online, it seems the US-SK105 is easier to find then then the US-OSK105. I believe these as well as the mini-split systems themselves are manufactured by Midea for Carrier and branded as such. There is also the US-SK105 (same p/n but without the "O"). The Midea US-SK105 is also referenced via Midea p/n 17310900003164. I see references online that the O does not matter an they are interchangeable. Why then two different part numbers? Can someone explain the differences (if any) between the US-OSK105 and the US-SK105? and confirm compatibility. If the US-SK105 should -work, I can order it from a site such as PartsHouse or Midea-Encompass.
Thanks in advance for any information.
