Home AC Troubleshooting Question
Posted on 3/16/15 at 6:15 pm

Is there a common reason for air to not be blowing cold besides low coolant levels?
It just doesn't seem to be keeping up even with temps only in the 80's.

If it's running outside, feel the small copper line. If it's very hot, wash outdoor unit with garden hose. Mail me $100

This just happened to my AC the last couple of days. Was wondering the same thing. Have AC tech coming over tomorrow. Hope it's just a coolant issue. Happened all of a sudden. I can feel the air blowing and it's not cold like normal, but not hot.

if it is not keeping up today, it probably isn't cooling at all...
turn the thing on and go outside...fan should be running....
check two copper lines coming out of the outside unit...large one should be cold and sweating and small one should be almos too hot to touch....
90% chance you need freon...

The small one should never be that hot. That means you have an air restriction on the condenser aka wash it

Freon could be low, or you could vacuum out your pipes (one near your fan and one near your ac unit) and pour bleach in the pipe near your ac unit

The air blowing out of the top of the fan on the unit outside should be warm also, if it's working right.

How many of you above experts are licensed HVAC mechanics?????

Tip--- find out before you call someone out how much is their service charge and more importantly how much they are charging per pound of freon 22. Should be between $30 and $50 per pound. Even at $50 they are ripping you off. You will probably only need 3-4 lbs of freon. The avg service call is between $80 and $100 per hour. Now, if the outdoor fan is running but compressor not, it could be a $15 capacitor. Good luck!!!!!

Not too hot. Have an A/C guy coming out today. He said I'm likely low on Freon and likely source of leak is evaporator coil.

What happened???
Posted on 3/18/15 at 11:29 am to moock blackjack
Refrigerant low. No obvious leak. Said that if problem recurs he would come back and find the leak and fix it. Said it was likely the evaporator coils or the outside unit.
Hopefully it's the evaporator coil since that's the cheaper to replace. Or even better, it's in a spot he can sodder.

Mine was the evaporator coil upstairs. He's measuring and going to price for replacement. I'm sweating bullets (literally). How bad is my bunghole going to hurt after this? Still don't have a price.

1200-1500 roughly. And fwiw I am a licensed HVAC contractor.

Let me know what the damage is. I'm hoping I don't have to do this again but I'll likely be in your situation in a few months.

There is a product I've seen work before. Its called EZ Seal. Its about 50 bucks, you put it in the freon. If you have a small leak, it will seal it. If its a big leak, no helping.
Posted on 3/18/15 at 12:13 pm to BigEdLSU
He mentioned it but said it usually only buys time. Also said it was bad for the compressor. Don't know if this is true or not.

I loved that stuff.
Explain to the customer "well you have a leak, I need to vacuum out the refrigerant, solder in valves, fill it with nitrogen, find the leak then replace the offending parts, then refill with 134a and then seal. "
or... I can use this syringe.
I was worried about it clogging a capillary tube, but the first unit I fixed with that stuff is still doing fine over two years later.

you likely just need a capacitor if you aren't low on coolant. It's an inexpensive part too.

I do not recommend or would use EZ seal.
