TCL Split air conditioning with outdoor compressor noise
Hi, I bought 12000Btu split air conditioning from TCL. The technician installed and in the same day after running, started a strange noise in the outdoor unit. I call the guy, he came in the other day and checked and said there is nothing wrong. Ok, i used 2 other nights the air and the sound still strange.
I came close to the compressor side of the unit and it does a strange noise, like if a strong snoring and curling the walls while moving.
Unsatisfied today I turned off, I opened the protective grid and turned the fan around, The sound did not happen. So I removed the fan and leaved just the fan motor and turned on the air. For my surprise the strange noise did about 5 seconds over the compressor side and stopped.
So, I mounted again the fan and turned on the air and the noise started. I discovered with this test that the noise comes from the compressor part and even stopping the FAN before the compressor stops it is possible to listen the strange snoring and curling from the compressor till it stops.
The indoor unity is working fine. The air is cooling well, when it gets the right temperature it turns off automatically and the thermostat works. All the options of the air are working.
I do not know if this is a problem or not, but I have two air conditionings GREE and they do not do any strange sound while compressor working.
Please advise what should I check, because I am very far from technical assistance and also it is expensive.
If you would like to have the video recorded of the sound i can upload to youtube.

This can only be a gas problem.
the split units goes on on and off if a shortage of gas is involved, the chances that you would here it wont be that big for the fans would make too much noise.
get a repair man for a re gas and all is well.
Sounds like the compressor is shuting down on high heat.There could be a couple reasons for this. 1 Check that proper voltage is being supplied to compressor. 2 Freon level may be low.This would be a service call. 3 Bad or intermitent connection at thermostat. 4 Main contacts to compressor sticking,usually burnt or pitted.

Ductless split air conditioning units are the very best thing for some situations. Of course they can be installed in the place of most any central air conditioning unit. They also are a very good alternative to window air conditioning units. I will explore the use of these units more closely and look at how they can be used effectively. One of the many problems encountered by the professional is when they are asked to install central air conditioning in an older home that was never designed with air conditioning as even a possibility. The walls may be very thick stone. Often they have very little or no insulation. The floor structures may be rough cut lumber. The joists spacing may be random. Walls and ceilings are plaster and lathe. Basically everything is stacked against any type of ducted central air conditioning. Many log style homes also are not very easy to get any kind of ducted central air conditioning installed. The open ceilings and the bare log wall design does not allow for any kind of ducting. I'm sure there are other situations. These are the ones that I have come across most frequently. If you have a home or building that falls into one of these categories you may want to investigate installing a ductless air conditioner. This type of air conditioner can be installed in almost any home or building. The small indoor unit can be attached to the wall with a few screws. Most of the units only require that a three inch hole be bored through the outside wall. In new installations the units can be placed on inside walls with some fore thought and planning. For installation in older homes or homes that are already built you will want to plan the units to be on the outside walls. The outdoor condenser units can be placed up to one hundred feet away from the indoor units. One outdoor unit can be used for many indoor units. Up to four indoor units can be attached to the same outdoor condenser. Some very advanced electronics will control the operation of the condenser and compressor to supply the refrigerant to the indoor air handler units that are running at the time. With variable speed technology the compressor and the condenser fan will only run as fast as needed. This technology has become very efficient in the last few years. You do not have to give up any efficiency with these ductless split units. Another advantage to these mini split air conditioners is that they can be controlled to run only in the rooms that you actually need air conditioning in. If you are not going to be in a room you can shut down the unit. The units also have timers that can be set to turn the air conditioning on or off at preset times. If you are not going to be home all day the air conditioning can be setback or turned off. The timer will turn on the air conditioning so that you return to a cool house. Central air conditioning is very hard to zone effectively. Also with large central air conditioning systems the outdoor compressor will be running at full capacity even though only a few rooms amy be calling for cooling. There are some central air conditioning systems that are do some staging and variable speed technology. These are not as efficient or as effective as the ductless split technology. Ductless split heatpumps are another great idea to look at. For a few dollars more you can also very easily have heat from your air conditioning mini split. Then especially in the mild spring and fall weather you can have some very efficient heat with out starting up that big monster of a furnace or boiler in the basement. In southern climates the heatpump version of the ductless split system may provide enough heat year around. Ductless split air conditioning is definitely something that can solve many problems for some homeowners. Add to that the many advantages of these units and you will find that they are worth every penny that you will invest into them. As with any project like this make sure that you screen your contractor. These units are not for do it yourself people. There are many things that need to be done correctly for these units to work properly and efficiently. A refrigeration license is also required to install these air conditioners. By doing a little research and hiring the right person you will enjoy many years of trouble free service from your new ductless mini split system.
I have the same problem with my TCL unit. I have had the Tech out to day and I am told it is an internal senor in the unit that fails. I am informed by the tech that this is a very common fault with the TCL unit. Also if you live in Australia like me prepare yourself for a fight with TCL due to them not liking to honour the 5 year warranty. I would not recommend this product to anyone
If you are renting your home, contact the owner or manager. If this is a window unit it may have a reset button at the plug. You also need to check the main breakers in the breaker panel. If its a split unit, I think you should contact a licensed air-conditioning technician to check it out. Find the REPAIR SERVICE tab on here and find one in your area or check the YELLOW PAGES in your phone book under HEATING AND AIR-CONDITIONING. You might want to talk with a neighbor to find a good air-conditioning technician. Without further information, I cant think of anything else. Hope I have helped you.
