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.

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.

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.

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?

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!

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?

It is a good idea is to add 50ml of sulphuric acid to the compressor before regassing to reduce corrosion

Our furnace is linking water underneath. The air conditioner man came out. He told us that we needed a water pump. He told us. Instead of letting water run down the pipe. Like it was doing. He will connect the pipe fm furnace. Run pipe outside the furnace. Run it into the bathroom. So it can be drained into our toilet. I do not lk that idea. Will this mess up my plumping? when an air conditioner person comes to your home. Does he check the air conditioner outside first? Thanks
@UserFriendly1989Ай бұрын
It's not necessarily bad for you plumbing but it will make a mess of your toilet over time. I personally think it's a terrible idea. Your furnace coil should be evacuating water through a trap and a pvc line into the drain in the ground. If applicable a condensate pump, but the condensate should have a vinyl tube dedicated to draining into a laundry sink or a secondary drain, sump pump pit, or even outdoors. Every state is going differ though.

Thank you for your content. It has helped me a lot. I live in Texas where the temps have been pretty close to HELL lately. It is 12:30 am right now. I put my thermostat on 68 at 5pm yesterday and it still hasn't reached temp. It's at 71 currently. The system does stop and start more frequently nowadays. We just got a new Goodman in 2020 and it hasn't had more coolant since we got it. Do you think it's time? Lastly, what's a fair price for coolant?

Shop around if you're concerned about pricing. It may be time to have a tuneup/cleaning performed. But it should never be "time" to add refrigerant unless something is wrong. Thanks!

2020 unit should be using R-410a refrigerant, get a quote of how much per lb they charge. You should see ice build up around the pipes. Is the air coming out weak and not so cold? I have one 19 year old unit that hasn't needed refrigerant added.

I thought these tips were helpful. Does the outdoor unit have a filter that needs to be cleaned? I change my indoor filter every 6 months.
@YT-User1013Ай бұрын
Not a filter but the fins on the outdoor unit’s coil may need to be cleaned from time to time depending on how much outdoor debris it’s taking on (leaves, pollen, dirt). Turn off breaker or pull the fuse, remove the top and shoot garden hose water thru the coil fins from the inside out. You may also get away with just shooting the coil fins from the outside in and not remove the top but that drops all the crap in the center and maybe on the compressor.

change out your capacitor on outside unit. If that don't do it then change out the fan motor.

And clean the outside of the condenser coil after you've killed the breaker(all power) to it. I just paid a pro to do that for me and that was the whole problem. Also if the unit is over ten years old, have a pro replace the relay(contactor).@@dickhertz8103

Most people don't have HVAC equipment for this. Pumps, vacuums, gauges, and tanks with compressed gases. Much more complex than something like replacing a capacitor.
