So the expansion valve is inside the outdoor unit ok thats good to know i figured ours was real low since the liquid line is cold as well while running AC it is still cooling fine but has frozen up a couple times but juat run fan for like 5 to 10 minutes and its fine but i think its a little low and i need to insulate out outdoor lines better because the stuff that came with it has decentigrated

Can you do this same refrigeration cycle breakdown but for a multizone heat pump system? My question is how does it direct the flow to each head if the EEVs are on the liquid line and not the vapor line??

As always great explanation. But how does the accumulator decide between oil and liquid refrigerant? Greetings from Germany

If i have a heat pump in heating mode and the suction line is not even that hot to the touch, Does that mean the metering device is defective? Or can it be the compressor is not working according to the designed parameter??

What is the minimum length of refrigerator line for mini split units? Is ok to install the outdoor unit right outside behind the indoor unit with maybe 3 ft of line?

Love your videos and would love to be as good as you someday. Less than a year in the trade, doing light commercial and residential. Luckily, I got hired by my teacher. Would you be able to teach us a basic on Chillers??

Hi sir, I have a quick question for you. I installed a two head mini split Mitsubishi system and four years later it’s not heating properly. My issue is the two indoor units are blowing lukewarm air. The outdoor unit is running fine and my vapor lines are 121°, what could be the problem could that be level on refrigerant because my vapor lines are pretty hot. If you could help, I would really appreciate it. Thanks for your video. It really helps. Thanks, joe

If I had to take a random guess, you probably blew your start and or run capacitor on the condenser (outside) unit. This happened to me with my central air. Those capacitors go out a lot.

I have a new ductless mini split, never use the heat mode yet, so how long does it take for the heat to start heating the inside for the first time ?

Is this considered a heat pump? Do mini split ACs with R32 that also havw heating mode considered both ACs and hear pumps?

Hello sir, i have three units connected with same outdoor unit but only one of them suddenly stopped working. All this without any message or light,giving only ambient air.All others work perfectly. Now my question is: can only one indoor split lose refrigerant or not? I mean is refrigerant in common or separated?thank you.

If you have a leak in one you've got a leak in all. It's all one system.

Since the refrigerant leaving the indoor unit is liquid, does the outdoor unit need to be lower than indoor unit (gravity fed)? The Mexican HVAC guys put my outdoor unit on my roof. They also don't weigh the refrigerant or evacuate the system. My Carrier 18K mini-splits are SEER 19 but each one is using 2,500 watts constantly.

So there’s no defrost cycle? Will the thermistors stop the control of the fan?
@Wilvan1809
@Wilvan1809 27 күн бұрын
Heat pumps like this will most likely use hot gas from the compressor discharge to defrost the outdoor coil.

Just imagine how people are being ripped off purchasing and installing heat pumps when you can buy a 3 way mini split for the faction of the price!
