Question about Klimaire 24,000 Btu 18 SEER DC Inverter Ductless Mini split Heat Pump Air conditioner

1 Answer

Squealing sound from our mini-split!

We have a dual Klimaire mini-split system that has been in our home a little over a month (one compressor, two units). One of them (in our bedroom of course) has started to make a high-pitched squealing noise every time the heater begins a cycle (no fan running). This lasts for about a minute and increases in pitch in the last 5-10 seconds just before it goes silent and the fan engages. Is there anything I can do about this without calling the repair guy (the best solution probably I know). It doesn't seem to effect the overall operation of the mini-split, otherwise we are very happy with the unit and it works beautifully. What causes this squeal? It wouldn't be much of an issue if we weren't trying to sleep at night when this happens. Thanks!

If it were a car I'd say something to do with the belt. Maybe check that out.

I have a terrible smell coming out of my Mitsubishi air-con.


after making sure it will drain properly the best way to permanently remove smells is to use a "ozone machine" or a ionizer this attacks the odor causing molecules and breaks them down. 30-60 minutes from a powerful unit will do the trick , most carpet cleaning companies that also do water repairs have these machines and their rates vary. alpine air also makes a home unit and these are good to use in the home 24/7 as well

There is a blue spark and bug zapping sound-looks like its sparking on the ceramic ozone plate. The place looks fine-no cracks.


It's doing exactly what it's supposed to do. The bug zapping sound is from dust particles in the air, that's being pulled thru the unit. However, it should not being doing in continuously (unless your home is really dusty), it may simply need cleaning. Cleaning the unit, about once a month is recommended.

Hope this helped you.

I need to clean the inside of the unit; the 4 fans and so on.


the best and easiest way is using compressed air if you have a little air compressor with an air gun on it that will work the best

Our air purfier woke me up to a sound of crackling noise. Is that normal or could it be a shortage in the machine.


It could be - if you turn off the lights, can you see any arcing (mini-lightning) inside the unit? If you see sparking, you probably have accumulated dust/dirt inside that will need to be cleaned out. You may also have a crack or hole in the discharge plate(s), in which case you need to replace them.

Let me know what you find.

I have this air conditioning unit where suddenly stops functioning and no power on the indicator. i have thecked the breaker and it is fine and ON with a three phase supply. I've checked the condenser at...


Hi, I will see if I can give you some idea of what may be happening. I work on these on a day to day basis. So, you have a split system with the condensing unit on the roof, or a package unit on the roof? Sounds to me it is the first one.So, you are telling me that the power supply at breaker below is OK, but you should have a power box at the condenser on the roof. When you reset power to the condenser, that's when you here this blast sound? To me from just hearing what you are saying , it would be the sound of the compressor trying to start up, and it has a internal problem making this noise. Tell me, when it makes this noise, does it trip the breaker again? If so, it is definatley the compressor. You can prove this if you are inclined to do this, is to find the 3 different wires going to compressor, and make sure power is off 1st. Disconnect them at the Contactor or remove the plastc cover from compressor and write down which wire goes to each terminal.Tape the ends so they dont touch metal. Turn the condenser back on and see if this blast is gone. If so, the compressor is dead and you will need a new one.You say you have 3 phase power? This is unusuall for a residential unit, 3 phase units are for comercial unit power. They dont use starting componants like Run or start caps because they have enough power to do the job.3 phase would have 3 hot legs of equal voltage unless it was the older 3 phase which will have a stinger leg with higher voltage then the 2 other legs.Maybe this is a commercial a/c. Also, the compressor is reversable on a 3 phase unit by moving 2 of the 3 wires on the load side of the box, like T-2 and T-3. If these are switched if the compressor is locked up, sometimes you can get lucky and break it loose.Please don't do this, I am just explaining to you a little about 3 phase. Try this so you can elimanate the compressor. The only other thing it could be, if this is a gas pack and you are starting the heat, you can be getting blow back premature combustion? But I don't think this is what you have. It has to be the compressor.So, lets prove it by taking it out of the circuit. all should hold and no noise.Still, a faulty compressor is not a good thing. Let me no. Best of Luck and safety first.
Sincerely,
Shastalaker7

Hi my old Honeywell 13520 has acquired a periodic squeal. I am sure it is a motor issue. Any way to tune up these little motors? (Brushes, etc..)


Usually if the motor is squealing, the bearings are dry no lubrication and worn. If you have oil ports you can oil it and quiet it down for a while. Most motors now have self lubricated or oil impregnated bearings, which you can't lubricate. It costs as much for somebody to replace the bearings, as it does for a new motor. Most people replace the motor.
