Hello PJmax, roughneck77 and others,

So after the refrigerant was added (almost 7lbs), 6 weeks past - and bam - no A/C again - as expected and predicted by you both.

I decided to find someone...

ah... so the coils would surely require an electronic leak detector. I've used the soap bubble test for the valves, joints and fittings and no apparent leaking at all. I presume it must be in the...

Is the soap spray method effective to confirm the schrader valves are not the issue? Any how does one confirm the coils do not have microleaks? Thanks.

Okay. Checked both schradsr valves via soap spray. Nothing. No leak. Darn! Was hoping for that to be the source? Checked evaporator coil with soap spray. Nothing. No leak.

Hm, how do I...

With soap and water - I checked the soldered connections and the entire visible area of the evaporator coils (see photos). No obvious bubbling.

1) how do I check the schrader vavles?

no electronic leak detector or any kind of refrigerant detector (sniffer). Is that 'typical' to just state 'it is not worth trying to find it?' The guy was very nice but also very 'matter of fact'...

So... as expected hvac company came - checked pressure and it was very low. Rep stated that they do not normally do a dye test to 'find the leak' as the cost of that in time and labor and...

Ahhh....... so that highly suggests there is insufficient refrigerant, correct? I was wondering why the entire coil was not completely frozen.

Any idea of price range for a recharge of...

Is it possible that the air filter being dirty and slowing down the airflow, caused the evaporator coil to freeze? and then even though defrosting the evaporator coil and changing the air filter -...

Gotcha. So I’ve got to just hope that the airflow and air temp improve now that the evaporator coil is defrosted and dried (left blower on few hours ).

Or is my refrigerant now low regardless of...

So now what? Hm. The ‘ice’ has now melted.

I did change the filter as it was quite dirty/clogged.

So I guess I have to hope that’s the cause.

Otherwise, I presume it is ‘low refrigerant’?...

Correction. A small area of the evaporator coil in the air handler is frozen. Turned off a/c and will run blower for a few hours. This will fix it?
I think I had done this intuitively yesterday...

By the touch yes... surely it is not frozen and the outdoor temp is now in the 70s - the line feels about 50-60 degrees.

One more thing... the air coming out of the fan (from above the compressor) seemingly was sometimes 'warm'/hot and then sometimes cool, i.e. seems to be varying temps. Could that suggest the...

but wouldn't I see 'icing'/frozen line if I kept it on and the refrigerant was 'low'? and cold copper line is about 50 degrees or so. The line itself is 'sweating' :)

But if there is air coming from the vents but no cold air - could it be that there is truly 'zero' refrigerant? And wouldn't I see a leak outside? No leak anywhere. No hissing, no bubbling, no...
