Our air conditioner got fixed recently because it wasn't producing any cold air but today it has gone back to just basically being a fan.. we tried switching it on and off on the main switch but nothing is really happening..

Hi.

It's summer.

I'm at a hotel and the AC is part of a central HVAC system, with a thermostat on the wall.

Problem is that even with the temp on the thermostat set at the coolest, the temp reflecting on the ac is still warmish. It's 26 degrees celcius (78 degrees Fahrenheit)

Feels like I'm in an oven.

Any ideas how to get the ac to be cooler.

If it helps, the model is a 2009 c & d fan coil unit. Thanks

Hi, any suggestions on how to troubleshoot are appreciated.

I have a 2008 era ducted AC unit (Temperzone brand) and its not getting cold.

here is what Ive checked so far:

Indoor Thermostat - working and correctly reporting inside temp

Blower fan - working fine, air blows strong from the vents

Circuit breaker - 3 phase CB is on, not tripping.

Outdoor unit fan - also turns on with the compressor

Compressor however starts about 2 mins after switching it on, it then runs for no more than 20 seconds (with its fan also running) and then the compressor (and fan) suddenly stop and do not come back on at all.

All the local AC tech companies ar on holidays. Whats the likely issues?

I’m a homeowner. I recently came across CYA Home Warranty while searching for coverage options for my HVAC system and appliances. With the unpredictability of home repairs, especially for older systems, I feel like having this type of extended warranty would give me some peace of mind. From what I understand, CYA Home Warranty offers a way to protect major home systems and appliances without the high upfront costs of traditional home warranty plans.

One of the features that caught my attention is the flexibility of the plans. For instance, you can add or remove items as your household evolves, which is something you don’t often see with standard home warranty providers.

I’d love to hear from anyone who has firsthand experience with CYA Home Warranty. Was the claims process straightforward? Did they provide quick and reliable repairs? How does it differ from insurance?

I’m particularly interested in learning how they handle claims for HVAC or plumbing issues—things that can easily cost a fortune if they fail unexpectedly. But any general thoughts or reviews about their service would be greatly appreciated! If you’ve used them before, please share your experience—it would really help me make an informed decision.

I have a 6kwh Panasonic Etherea air conditioning unit in my living room. The room is about 4m wide x 7m long x 2.4 high. On the whole, they system seems to work fine and heats and cools the room as needed. However, it does seem to cost a lot of money to run.

I've noticed that It seems to start blowing air every 5 minutes, no matter what. In the image below, the thermostat is picking up that the room is 24 degrees C but I've set the air con to 19 degrees in heat mode. I would expect it to just turn off until the thermostat reads 19, then start blowing to keep the room that temperature. I would expect in auto mode that it would start blowing cold air at this point to reduce the room temperature, but in heat mode I'd expect it not to.

Am I misunderstanding how it works or is there something wrong with it?

AC Running once per day, demand is st start every hour.

I hear the compressor starting, but no airflow.

Last week I replaced the Condenser Capacitor (outside) , and the A/C ran great for 7 days.

Now, no air flow (but maybe once per day)

Any suggestions?

Q: if I start the heater, would both Condenser and Evaporator Fans run; or would only the Evaporator Fan (Blower) run? *to help me troubleshoot

Hi Everyone!

I have some specific doubt on the functionality of Samsung 1.5-ton, 3-star, 5-in-1 convertible, Wi-Fi-enabled AC.

Model: AR18CYLANWK

Can anybody please clarify the doubt if you have this AC.

1. In WindFree mode, can I manually adjust the temperature to my liking, or is the temperature locked in this mode?

2. In convertible mode (specifically when set to 60% capacity/Economy), can I still change the temperature freely, or is it locked at a certain preset?

Thanks in advance for any insights!

Ive acquired a new in box ducted system for my house that I'm preparing to install over the coming days.

I don't have any of the duct work or vents. That's easy sorted.

I can't find a supply V-Box for this unit anywhere online, do they not exist? I'm looking at just buying one from a very similarly sized unit and modifying it to fit, There's no obvious reasons why I can't do this?

I'm a sparky but I'll have a fridgy come out and do his bit

I have a portable aircon unit that work fine - except when it is cooling. When I (assume) the compressor turns on, it sounds like a jackhammer. It’s noisy enough to be heard outside, and far too noisy to be able to sleep. It does cool though, very well.

When the cooling cycle ends, it goes back to the normal sounds.

It’s the middle of summer here and I can’t afford to get a new unit. Is there anything I could do to fix this? Any YouTube videos I should be watching?

Any idea why the compressor might be vibrating so hard! There’s no leaks etc, cycles on and off constantly at night but doesn’t shut down… was shutting down at night but that seems to have stopped. Copper lines are all cold and it’s condensing normally. Cold air, but not super cold.

I’ve got a video but can’t upload. It’s not the fan, it’s the compressor physically itself vibrating like crazy!

I’ve noticed that some AC units have Economy/Power Savings button on their remotes, but when it is activated it, the temperature is locked at 24°C, which I don't like.

24°C is cold for me.

I’d prefer to adjust the temperature to 26°C or 27°C without leaving Economy/Power Savings mode.

Which AC model offer this level of flexibility ?

I I have a OEM YORK Central Air Conditioning Wire Controller on my wall (as pictured), unfortunately, I do not know what's the exact model.

Recently, the landlord locked the AC to 22 degrees. I'm trying to get a paper clip into it to adjust the temperature but I noticed 2 things:

1. The blue backlight is on continuously. Previously, it would only turn on when unlocked and any button was pressed.
2. I tried pressing the mode & fan speed buttons together, which previously had turn off the lock 🔒 icon and allowed me to adjust the temperature.

What did he do? How can I unlocked from this specific lock mode?

Okay, so we just bought a new variable speed fan AC unit, properly sized. It runs well. The issue is that when it's initially turning on, it turns on and off 4 times before staying on. Every time. What's causing this? Is it normal? Doesn't seem normal. If it's not, is there a quick fix? Thanks!

We had ducted air replaced months ago. A big, expensive unit. My kids rooms (upstairs) are always sooo hot. No matter how much we adjust the different air flow, or put vents on climate or open, they are always so much hotter. See Picture. This is downstairs- a sensor and next to it a button to open or close vent. The kids only have the button to open/close vent. We only have 3 of those black sensors, 2 downstairs and 1 in main bedroom (these rooms are always comfortable). But when I google the silver vent buttons, I'm reading they are actually wireless sensors? Are they? If they are, why would we additionally have the black sensor buttons in some of our rooms?

I rent a 2/2 condo…

Just moved in and the 4 vents near the air duct blow VERY strong, while all other vents blow as strong as a 100 year old blowing out birthday candles…

I know I’m only renting but it’s terribly bad in most of the condo, is there anything I can do OR something I can make my landlord do? I know that vents near the main AC unit have things that limit their air output but it feels like they don’t exist.

Any advice or opinions are appreciated. Thanks y’all!

Pessoal, as aletas da serpentina do meu ar condicionado estão esfarelando por conta da maresia (moro perto da praia) por conta disso eu acho que é mais barato trocar a serpentina do que comprar um ar novo, o problema é que eu até acho a serpentina do mesmo tamanho, mas tem uma diferença, observando a foto em anexo fica fácil de explicar:

https://preview.redd.it/ps8kml3li89e1.jpg?width=723&format=pjpg&auto=webp&s=fcacf4d97c22a1a7b5a60901994e8e6fb7799110

A serpentina que eu achei pra comprar tem esses dois "desvios" que eu apontei com a seta, já a serpentina que veio de fábrica só tem 1 desvio, isso poderia prejudicar o compressor ou diminuir a eficiência do ar? Eu também achei uma serpentina que é toda preenchida, não tem esses desvios, qual a diferença?

Howdy all, I've been struggling for a while to find the right combination of items to make this one particular room a set temperature and humidity range. Thinking of getting another window A/C, but what I'm wondering is... how is the air infiltration from outside to inside? I don't mean from the unit blowing the air, I know that's the same inside out, and I don't mean the siding/weather stripping involved - I'd be siliconing/weather stripping that a ton anyways.

Humidity in this room is a huge no-no, so I can't have the ever oppressive high humidity outside 'leaking' through the unit.

What I'm wondering is if the unit is OPEN at all to the outside? Like if I were to look through the vents or anything, would I be able to see outside?

Is there a passive exchange of air if, say, the unit is turned off? Or are they 'fully' enclosed?

Thanks!

Hi guys, my ac is very loud, just wondering if this sounds normal? This is a brand new AC unit.

I have a cost way portable AC, and when it reaches the target temperature, it stops for quite a long time, and the temperature increases quite a bit. Do you guys recommend an AC that does not stop (when min temp: ig if too cold, it damages the ac - please share your thoughts on this) or that quickly restarts when the temp increases.

The minimum temperature is like 16C. The problem is that it reaches 16 and then it stops for so long that the temp gets up to like 18.5. So I put on a lot of blankets and then I get hot when the temp goes up. I wonder if there’s an ac that detects temp better and restarts when the temp increases less - like 17 for example

Thanks

Traiden mini split unit. Anyone know what this icon under the 68 means? Appeared today and my unit isn’t cooling. I can’t seem to turn it off either. I’ve owned it for about 2 months.

This is a thru the wall AC and I need to replace the plastic that borders the slot for the AC and the AC itself, making it a snug fit. I can't for the life of me remember what this piece is called? The other side of the plastic has blue styrofoam if that helps...

So I want you guys to speculate as i dont have a way to measure energy consumption atm.

Heres the deal: Outside temp: 29/30 celsius Outside hunidity: 92%

When I set the unit in dry mode targeting for the same outside temp (30c) the room ends up at 74f (23.3 Celsius) and 49% humidity.

Cool mode: Target 24 Celsius i get 76f ( 24.4 Celsius) and 65% humidity.

In dry mode the room feels noticeably cooler.

My questions:

1. Am i spending more or less energy while using the dry mode ?

2. Why is the unit cooling the room way more than im asking it to do in dry mode?

Any insight will be appreciated!

Just a question to any HVAC people out there is it normal for a gree E-TAC unit that has the AC and heater that they use in a lot of hotels to not get hot when it's extremely cold outside like in Virginia Beach it's 38° on the ocean front and the unit does not push out hot air and I don't want to keep replacing the whole unit if it's just too cold to produce heat
