Superheat Charging Chart- How to Find Target Superheat and Actual Superheat on an Air Conditioner!

Superheat Charging Chart- How to Find Target Superheat and Actual Superheat on an Air Conditioner! Calculate the Wet Bulb and Dry Bulb Temp using the chart to measure the refrigerant level.
This is how to use a Superheat Charging Chart, To Know How to Find a Target Superheat and Compare it to the Actual. We go over How to know the Actual Superheat of the AC Unit you are working on Compared to the Target Superheat in order to tell if you are Low on Refrigerant or have Too Much Refrigerant in the system. You must make sure that the Refrigerant Charge is as close to the target superheat as possible since you would use this Charging Method for systems with fixed Orifices/Pistons and Capillary tube Metering Devices. Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.

Me and my husband own a HVAC company for 15 years but he don't have much patience for teaching. We have about 12 service techs/installers working for us and pick up subs in the peak season. He links your videos to them, they are so simple to understand, even I understand it. Keep up the great work! YOU HAVE ONE OF THE BEST HVAC YOU TUBE CHANNELS!! Kristina

[DaannyyTrraann]

thanks for calming my brain down with this amazing explanation!!

[bhampresson]

Man thanks so much for your videos! I took HVAC up in school for a bag up incase the steel company slow down. Doing HVAC at a hospital now!

Awesome series from AC Service Tech. Excellent explanations and great details.

What’s the Effect of slowing the blower on superheat? (Yes, a piston)

Thanks for your work, this is an amazing channel. I find it fascinating.

[jimbola]

man I love your video's very patiently explained!!!

[scotthsmith]

Thanks for the refresher between you and another You Tube video I was able to perfectly dial in and charge my system purrfectly. Thanks

how bout if it gives you around 95 temp 60 wet bulb what the x is ?service tech?

[rbautista]

What do you do if temp is 100 and wet bulb is 62 the chart shows x how can you check charge then?

[dandearman]

Thank you for explaining this so it made sense. A guy at work tried to explain this to me and made it sound like it was rocket science. Have you ever done a comparison using the chart and using your gauge pressure and temperature readings on the refrigerant lines?  I was wondering if this chart would hold true for automotive air conditioning?

What should a tech do if the temperatures intersect in the dark shaded area with the X?

[jimbola]

excellent video thank you for sharing!!!!

[SS-ufde]

Awesome video.. please post more such videos.. I have doubt ..Is subcooling and superheat calculation procedure are same same for TXV n Non TXV system? From where can I get superheat and subcooling chart for R22, R134, R404, R 410, R407.. hope to listen from you soon..

[russellsalinas]

I’m confused now because the formula for finding the superheat is the actual line temp minus the saturated temp/pressure in the middle of the evap = actual superheat. But now you’re saying to use the outdoor temp instead of the line temp. Is the line temp the same temperature of the outdoor temp?

[lakersfankb]

Is it ok to take the wetbulb temp in the return duct itself before it enters the air handler ? thank you for this video, really helpful.

[hondaclub]

What is a good “wet bulb” thermometer?

[HowToDoitright]

Thanks for the video. So to get the target superheat we have to measure the outside temp and inside wetbulb and follow the chart to find out our target superheat and then use that value to charge the system correct?. But when we start charging our system wouldn’t this change the inside temperature to cooler dropping out superheat value?

I’m getting a little off topic. I have a temp split of 25 degrees today and my blower is running fine, it was not dirty. I ran the unit with no filter because the one it had was super dirty and I didn’t have one at the moment. Checked charge with superheat method and it was telling me I was overcharged. Will that cause my temp split to go high? Or will an airflow problem cause my superheat reading to tell me I’m overcharged although I’m not? I hope I’m making sense. Thank you in advance
