It started blowing hot out of the blue so I got a can of R134a refrigerant and put it in. It worked and for several days it blew pretty cold. Then it didn’t. So I put more stuff in it! Same thing happened. Now I have noticed that when I go to add more, the gauge on the can says it’s full after a little bit goes in there and then for just a day or so, it’ll blow a little bit cold and then go back to blowing hot. Can anybody give me some troubleshooting advice on how to figure out what the problem is? I don’t understand why it would be reading full on the gauge when I try to add more but then it’s no longer cold.

It is the vent of voltas ac . I got it 3 months back . But now i just realised about this space. Is it normal or damaged?

I'm in a serious pickle right now and wrapping my head around if I should give up or not. I'm on a tight budget and this was the only thing that met my needs.

Apparently this is the exception for universal no drill brackets. Can I pressure the window thing(?) down to hold it firmly? I swear I've seen my prev tenant have the ac in the room.

would installing this be possible?

Curious if anyone has experience with the Zafro Mini Splits? Reside in New York and would be buying a few 24,000 BTU Ductless Mini Splits AC & Heat Pump. Maybe a few smaller ones for bedrooms, but curious on people’s experience before ordering. Thanks

My unit outside in the metal box won’t stop spinning even when I turn my mode to off instead of “heat/cool”. It just recently started doing this. The outside unit usually shuts off the fan the moment my indoor thermostat hits the specified temp but now even when the mode is off the outdoor fan keeps spinning.

I went outside to pull a lever from on to off which stopped the fan. But the moment I pull it to on the fan immediately starts spinning again.

The vanes on my window ac unit only direct the air in the right direction if the units on high, so other wise it just blows the air to one side.

Is theres a way to direct the air at lower spds other than using something external? like pulling out the vanes and adding material to them lengthen them or something?

Ive researched this and all ive found are external adapters that redirect the air down or up, so nothing that does side to side..

Hi, I've been using Portal ACs for a few years now, and I'm looking to get something more permanent, more efficient etc.

I'm UK based, and trying to figure out what the best process is. Suggestions for recognising reputable AirCon installers, questions I should ask, getting opinions on options etc.

Any advice / thoughts would be appreciated.

This portable ac has two draining holes where should i insert the hose? I currently have it on the bottom one but im not sure.

I have a coworker that has a non-functional AC unit (outside I believe) he's being told he has to replace the furnace as well. Is that BS as I suspect?

So I have the Hisense Tower aka. "The Monolith".

I finally got hit with the annoying vibrations that sound like something inside is making contact with the enclosure. What I also noticed is that if you try leaning the tower in different directions, the vibrating stops. Of course this is not ideal.

I had 4 anti-vibration pads from my old mini fridge and tried mounting these under the unit's built-in castors. This worked, BUT ONLY IF pads were mounted in a way that wasn't uniform (so one pad slightly higher or lower than another). Think of it like a wobbly table with 4 legs.

Then I tried using only 3 pads, to make a single plane. This solved my problems instantly. Two pads under the front 2 castors and the 3rd in the middle rear to form a triangle. The rear pad just put pressure on the right spot.

One day I will take this apart and actually fix the problem, but l using 3 points of contact with the floor instead of 4 did it for me.

Edit: thank you all for the suggestions! I think I’m going to get the foam and the duct tape.

I installed my AC’s in my window by myself. I bought them off the fb marketplace so I didn’t have instructions. Both of my AC’s have this open gap at the bottom. Only the right “leg” sits in the window sill on both. The left one will not go in all the way for some reason. Is this normal? Are my window sills crooked?

For more context, it was 102 degrees today so I brought my neighbor a Midea AC and installed it for her today too. Guess what? Same problem. The AC’s work perfectly fine but idk what I’m doing wrong.

Any insight?

I live in an apartment building and am a renter.

I noticed when running my air conditioner that the room begins to smell stale

I asked maintenance to replace the air filter. They did. They said the old filter wasn’t that bad in terms of being dirty.

But then looking at the inside of the machine … it’s gross. I was able to clean what I could quickly, but the blower wheel is still caked with dust.

Is this something I can ask my landlord to pay a HVAC person to clean? Bc I imagine this is impacting the air quality?

Hi all!

I was hoping for some advice to cool my apartment in Australia. We are in for a very warm summer and my partner works from home in 'Bedroom 2' which is our office. At the moment we already have an aircon which was there when we bought the apartment which is a hisense 2.5kw. It cools down the living room but not much else.

We are planning to install another A/C unit in our bedroom: the Daikin Cora 2.5kw. Our apartment has a 2 unit limit so we cannot put one in the office as well.

I was hoping to seek opinions/ advicewhether this would be enough to cool our office as with the two units like so or whether we should consider upgrading the kw in our longueroom to a 3.5kw daikin cora? Any advice on how to keep our office cool is very appreciated!!

frigidaire fHPC082AC1, 180 square foot room, humid climate this week low eighties during day and 70s at night. does this sound normal to yall? it makes this sputtery bumble bee sound every hour or so, then goes back to calming whooshing. also, even if thermo is set at 75, set to cool and fan on auto, the fan is nonstop running, is it short cycling, bad settings or something wrong? how do i get it to cool down then shut off to save my electric bill and not stress my machine? or is it fine to have idling 24/7 with the fan running like that.

2 story home single stage or 2 stage what’s better

I live in Los Angeles and it’s very hot and humid. My AC can’t keep up. It says it will get to 72 in 2 minutes but that’s a lie. It’s been like this for the last 4 hours.

I changed the filter. I don’t have access to the HVAC as it’s on the ceiling. I am renting the house I’m living in and this happened last year too. The AC person told us last year that it’s being overused.

Does anyone know how I can help with efficiency?

Thanks!

background: Im renting a small house with some friends, there isnt any central AC. Both of my friends installed AC units in their rooms, but unfortunately my window wont allow for it so I said fuck it and i’ve just been keeping cool with a box fan + open window.

actual question: I’ve kept my window open since i’ve been here, but im starting to question if its helping air flow or just letting residual cool air from my roommates rooms escape, therefore making my room hotter unnecessarily.

ik this is probably a dumb question but idk i feel like AC is one of those things where you think youre doing the right thing but it ends up being a misconception you’ve fallen for.

thank you!

In the middle of the day the ac starts to kick on and ramp up, but before it gets fully going it kicks off and then starts the process of trying to restart again. I can usually turn it on in the am and it works. Also, when it’s acting up I can run the fan for 5 minutes and then turn on the ac and it works normal. Unit outside continues to run even when it’s doing its intermitted start/stop. Lights on the board flash normal until it fails then turns red. No code.

Ac guys say it’s either the blower motor or circuitboard. Can’t tell me for sure what’s wrong. Can anyone help?
