Outstanding information. You are truly one of the technicians like myself who are passionate about HVAC and obviously enjoy what you do. I would appreciate any future info on troubleshooting mini splits including the high efficiency ducted systems. Also maybe some general symptoms that a Mini split is overcharged either the sound that the compressor is making. I have been doing all types of HVAC/R work for over 20 years with a background in electronics and seriously, I am impressed with your videos so definitely keep it up.

@ranckie5055 Год назад

Great video on stressing the importance of a proper installation. There are far too many You Tube videos that fail to stress how important it is to have proper flares on the tubing, doing a proper evacuation using a micron gauge and hopefully pulling the line set down to around 200 microns, using a good sealant like Nylog on the flare faces, pressure testing with nitogen to at least 350 to 400 psi and doing a leak test, and finally, using a torque wrench to torque the nuts to factory specs. I'd bet that many of the bad compressors you've encountered were failing due to the corrosive refrigerant caused by a poor evacuation that left moisture in the system, which caused the acidic condition. Some folks just have to learn the hard way.

Great breakdown but I will stand by my view that most mini splits are way more complicated than they need to be as far as communicating and all that stuff. Just make it standard 24 v like a normal split system because in the end that's all a mini split is just smaller.

@skipsaunders5974 Год назад

Around 26:30 you mention water running down a wall ... caused by a drain issue. This issue can be horrendous if the installer of a multi-head system decided to link two drain pipes together before the pipes reach the outside of the building. If you blow on the outside pipe, the non-clogged drain will spew liquid and gunk all over the customers room. If you suck on the outside pipe, you might collect the gunk and water from the good head unit, but the clogged one will remain clogged. Do not allow an installer to link the two drain systems before the pipes get to the outside. You should have one drain pipe for each indoor air handler.

Nice video! I will follow you... Just some small remarks: L/N to F1/F2 on ODU is not protected, it will cause PCB damage, between ODU and IDU it is protected (as far as I know). The F1/F2 is NOT polarity sensitive (as far as I know). I am a service tech in EU, please check via Samsung HVAC. Compressor windings to earth (chassis) resistance must be checked with using an insulation tester (400-500V conductivity test). :)

@estevezcarlos67 10 месяцев назад

Thank you for this video. I have a question. You have repeated several times that you pressurize the mini split systems with 500 Lbs./PSI of nitrogen. Does that not compromise the evap coil as most mini split evap coils are rated for 340-350 Lbs/psi? I've never heard of a system being pressurized with nitrogen to such a high level. Apart from that I found your video very informative. Thank you

@@TaddyDigest i do install them still, in fact I put 4 in last week, but I find on 40 degree celcius plus days they get a lot of compressor overloads, and I tend to oversize my systems a bit for when those days inevitably come.

Mini split head units have a common problem of making a loud (if you are trying to sleep) pop whenever the cooling cycle kicks in, as something inside like the blower motor housing or drip pan contracts from the temperature change. I haven't seen a fix for this anywhere online (i have a Mitsubishi that does it). The manufacturer considers it "normal operation", but it really is unacceptable, and it is a source of much buyer's remorse and difficulty sleeping for many people. You would be a hero to thousands if you could find a fix for it!

I have three wires going to the indoor unit (2 power) (1 communication?) and of course my line in. I have power at the AH, and the thermostat is working. However, I can not get the condenser to come on at all. No noise, Nada. No error codes either. Any ideas? Pressures seem fine as well. 25:00

We have a total of two indoor units and one cools fine(artcool) and the other does not, blows warm air(standard type). The artcool blows and works fine 44 degrees but the standard one at 77degrees and wont cool. it shows the compressor is on but doesn't cool. could use your advise Thanks Jim
