My A/C condenser in the backyard just stopped working, about two hours ago. The fan continues to blow. And the heat is rising.
The office of the company that installed it opens tomorrow at 7:30a (I live in Eastern Daylight Time).
My friend N brought up a good point. I got the unit last year. So it should still be under warranty. (You know, tomorrow will probably be one of the hottest days of the year.)
Any advice you can give will be graciously accepted. 
I am not an AC repairperson at all. I can mention a few things that have happened to me in the course of home ownership. First - have you checked the circuit breaker? There may (should?) be more than one of them.
Is the coolant line covered in ice or frost?
Call em first thing. Try to be nice!
And consider yourself lucky. My (insert important appliance here) always breaks Friday Night before a huge holiday 3-day weekend.
How do you know it is the condenser? I would flip the breaker to it, let it sit for an hour to possibly de-ice (if that is the issue) and discharge, then turn it back on. As it isn’t cooling anyways, turning it off won’t hurt it and it may solve the issue for now.
ETA: Is it hotter than the inner hubs of hell outside where you live? Sometimes the unit just can’t keep up if it is very hot and underpowered for your house. But, I’m not an HVAC guy.
Start or run capacitor is a likely culprit when an AC system fails. But they normally fail after 10 years or so. It’s still a possibility, I guess.
During recent high temperatures, I noticed the air conditioning at work wasn’t keeping up. It was getting pretty miserable, so I called for service.
At the beginning of the pandemic, I laid off some employees, one of whom was in charge of replacing the filters in the furnace and air conditioning. TaDa!
I just had my A/C fixed last month. Same symptoms, it was the capacitor and a relay.
Yeah, the actual compressor and evaporator and all that stuff tends to last for a very long time. The fans, the capacitor and the relays fail more often.
Over 14 years in this house, we’ve had the outside fan replaced a couple of times(the demands on them in Texas summers are pretty extreme), and a capacitor once, but the rest of it is still going strong.
Did you get it fixed? Enquiring minds, etc, etc.
@Sunny_Daze I got it fixed yesterday . Apparently a blown fuse. It has been rather hot here, and I probably have been overworking it a little. The repairman also said to wash out the cottonwood. But the hose in the backyard doesn’t work. (He said he’d use the one in the front. But I never stayed long enough to see if he did.)
Also the A/C doesn’t seem to be cooling like it did before. Am I imagining things?
Cottonwood fluff has been the death of many an A/C compressor. The neighbors across the street have epic cottonwood trees that probably predated the neighborhood. Monumentally stupid trees to leave up, IMHO, for a variety of reasons. The most relevant of which: every cottonwood seed season, the entire area turns into cotton pickin’ fluff. My compressor sucks in enough cotton to knit thousands of pairs of whitey tighties. The high water pressure and the convenient back-yard hose are the only thing that makes the situation salvagable.
