AC LOW on Refrigerant! How To Know!

In this video, Joshua Griffin share some of the symptoms, that air conditioning and heat pump systems have when they are low on refrigerant. Some of these systems can be detected by a homeowner in the event they believe their system may be showing signs of low Freon or low refrigerant. Follow this list if deciding, whether or not your air conditioning system is performing different than it used to. Make sure to call professional if you believe your system is low on refrigerant.

A couple of years ago my AC was not working as well as it should had the AC company come out and they told me it was low on refrigerant but they wouldn’t fill it up. They just wanted to sell me a new AC unit. Had another company come out top off the refrigerant and it’s worked great for the last couple years.

5:28 Exactly my problem! Thanks for your help!!

OMG!!! Congrats on the official Daikin sponsorship!

[HomeRapidRepair]

Great topic. We come across this one a lot during home inspections…

[craigclingman]

Great information, Josh!!! My air difference is 10 degrees F, so I'm thinking I need a recharge.

I'm learning diy hvac. Fascinating. Very informative. Thanks for sharing. Much Blessings to you. 🙏 Lord-Jesus-Christ ✝c✝o✝m

[Sergio-ihlk]

Thank you for your knowledge it is appreciated. I live in Miami Florida pretty hot here I gotta learn a little bit more about a c's Just saying

[michaelbaldwin]

Everyone of those symptoms have about 4 other issues that could be the problem. Not to mention all these pm’s that loose refrigerant and then in 2 or 3 yr they have pay for refrigerant and possibly a leak test.

Hello, good video. Have a question. What is a good temp to set indoors when outside is 90F or more?

[drzsy]

What if the AC seems to be running fine with not short or long run times and blowing cold air; and the tech says the sub cool is low and superheat is high? This seemed odd that there would be low Freon. My evaporator is rusty but seems to be running fine. Could the system still be failing as it does not seem to add up. Filter is fairly new.

Outdoor unit free online not cold no condensation no buildup replaced with brand new capacitor where should I go from here

[waltofalltrades]

I guess my problem is that I live in a tin can (old mobile home) in the south. There's a 21 degree difference between the return air and the cold air coming out the vents. That's with a 93 degree outside temp too.

Thanks a lot for the vid! I have a strange problem with my indoor unit- have to say it is just a simple split unit with one wall mointed indoor room unit and an outdoor unit. The catch pan as well ad the condensate line is clear and working. The unit is also cooling but it is leaking on the flaps and drops on the floor. It seems that water is condensating on the flaps and air guides. Could that also be a symptome of low refrigerent? Thanks a lot and best regards from Germany!

A dirty evap coil that’s covered in hair and dirt will do the same thing as a low coolant freeze over will do…..I clean the evap coil every spring…

[tannermikal]

… after 36 hrs of slaving away in dog days of summer I come to realize you’re explanation for low refrigerant and guarantee that’s what mine is bc tried everything else 🤣 it was leaking past pan too and then froze up and yea pain in the rear.

[edzanjero]

I have a 30 yr old Goodman R-22 and coincidental to a failed run capacitor and a disconnect fuse, the evaporator coils stopped outputting condensate. No ice on evaporator, no frost anywhere. On a hot day the evaporator will normally output a few gallons, but now zero. Register outputs are coolish, but not cold, and low volume, insufficient. Outdoor unit running normally, clean coils. Suction tube cool, not cold, no short cycling. I'm puzzled why one day there was normal evaporator output, but after repair, none. All values correct on compressor & new cap. Contactor measures normal. 26VAC from thermostat. Ideas?

[skipsaunders]

would be useful to see the symptoms for a split system using inverter compressors and Electronic Expansion Valve (EEV) technology

[richardremmers]

What's the best tool to check DeltaT?

[kevinhuggins]

My unit is taking a long time to cool. But only some times and not all the time. The line coming out of the compressor is not very cold. The line going into the A coil is not very cold. The air coming out of the vents is cold but not really cold. It was 103 today and it kept my 1400sqft house at 73° when it was set at 70°. Do you think I have low refrigerant symptom?

[donpablos]

Can low refrigirant be another reason for high pressure in the system after 10 min of running, ie, above 550 psi (while only 270 expected under current conditions) ?
