House A/C not cooling....

[opus1776]

So on Tuesday evening I was near one of the vents in my house and noticed that the air coming out was not that cold. Crap A/C not working. Went outside and the fan was running at speed, but the exhaust air was not that warm. The furnace filter was changed about a month ago---checked it again and it was in good shape. Went to the furnace and grabbed the copper return line to the outside unit and it was room temp---not warm like it should be. When I got home on Tuesday, the house was cool--- so the A/C was running earlier in the day... I am hoping that the condenser only needs freon (last topoff was 6 years ago).....

I would reach out to churchmouse for help, but he's retired now. Who are the other folks on INGO that do HVAC. I'm in New Whiteland...
tnx for help....

Typically if it was low on refrigerant it would freeze. I’ve had a slew of capacitors go bad this year so it could be the compressor cap. Not hard to check if you’re reasonably mechanically minded and have a meter that can check mfd’s.

Similar here, heat pump not warm, a/c barely cold.

Suspect bad txv, but to replace them the system must be recovered/evacuated and is very expensive.

There’s a fuse block/resistor thing outside near the AC unit (I’m not electrician) but we had to have ours swapped last year. Wasn’t Freon etc. was this big ol electronic fuse or do-dad

We are having humidity issues. House to temp. But 70% humidity. Not fun.

I do hvac work and am in Franklin.

Going to guess since I can't see it, but going to guess you lost your capacitor.

Heat gets them.
It can work/fail so the fan outside runs but compressor will not.

Yesterday was a busy day replacing caps. 3 in a day and adjusted the charge on 2 more. Had to clean cottonwood off those two. People… CLEAN YOUR COILS OFF! There’s the friendly INGO PSA.

it is to big for your house.....does it run short cycle?

Just a followup....DocIndy fixed me up. the cap for the compressor the bed.....

This is what newbies running for the classifieds don't understand! We are just as much about helping each other out as about the guns.

My AC slowly stopped cooling today. I just had a pretty major repair done
2 1/2 weeks ago. I hope it's on their dime and not mine.

That's why I keep a spare on the shelf.
(Along with a window shaker)
Happy wife....

And you left it running..

It is all too often the condenser is right near the dryer vent. What this causes is lint build up on the coil and depending on how much laundry you do it could be a monthly thing to clean the coil. It is at my house.

Hope they took care of you.

We had a new one installed that was smaller. Not sure on cycle length as we leave fan on all the time. I think the coils probably dirty, and 100% humidity outside

Here, Here, I agree!
Cleaning the outside coils is one of the best things you can do to keep your system running good.
Changing filters (quality), is right up there too.
My Trane system is 17 years old and holing up very well. I've always kept up with filter changes and cleaned the outside coils several times.
Last year I had to replace two capacitors (one at blower motor and the other at the compressor, outside), all done myself.
If you're comfortable with DIY projects of this nature, clean those coils. Plenty of youtube videos demonstrate how.

DocIndy, do you like Nu-Calgon, Refrigeration Technologies or are there better brands for the DIY professional homeowner?
