Its a balmy 89 degrees here at Shea Saul. The AC has done this before, but usually it "fixes itself" after awhile. I'm not so optimistic this time. Does anyone have any idea what it could be, and how much it would cost to repair?

It might need replaced all together. I think its the original unit (condos built in 81). How much do these things usually run? I've got a 900 sq foot condo...so I don't think i'd need a monster.

Actually since it's working, that's probably not the problem.

Our AC man was here the other day and he dumped a bunch of freon into our AC.

You might be out of freon.

Saul,

Check the Central AC unit.
Check if any of the pipes or frozen.
They're supposed to be moist not frozen.

If frozen, you need freon.
The next thing is to spray off the AC unit getting all of the dirt from between the coils.

That should make a difference.

I'm well versed in this as I've been going through the same thing you have.
It was blowing cold but not cold enough... All I needed to do was spray the 1/4" filter of dirt off and it was A-OK.

Spent a $35 service fee but it was worth it.

Also make sure your air intake filter is clean...I've found out the hard way that, next to being low on freon, a dirty filter will cause the line to freeze.

If it "fixes itself", that points at high head pressure with the condensor freezing up. When the condenser thaws, it starts working again. Usually this is caused by your outside coils being clogged with crap. Get out the hose and clean it out, and chances are you'll fix the problem. If you have not had someone check the freon levels for a while, that would we worth looking at too. Once a tech throws a test set on there they will be able to tell right away where to look.

As for opening the windows - anyone that has lived in Kansas knows you don't open windows there, that just invites the feedlot smell inside.

See if your A-coil is frozen over. If it is, you probably have a plugged air filter.

Otherwise, you may have a blown fuse out at the compressor.

yeah, check for at fuse near the outside unit. Also check the air filter, a really dirty can restrict the flow big time also.

Probably low on freon. See if the outside unit is spinning at all. Most have a low freon shutoff switch.

It’s that huge meat packing plant outside town. What your smelling is them burning off blood. :Lin:

If you didn't it would be worth your time to do so. Next time it would cost you under $10.00.

Did your AC guy find anything else wrong with the unit? If it blew the fuses once there could be a reason for doing so.

Then again, it could be just that your building has queer electrons that run rampant blowing fuses.

Real question.... Why did the fuses blow? cured the symptom, not the problem.

It usually happens when the A/C is first turned on at the beginning of summer. The compressor parts corrode together and cause a hard start, leading to blown fuses.

If your a/c ever fails to start at the beginning of a/c season, that's the first thing to check. It's a cheap fix, unless you're Saulwhippedguy.

I've seend brownouts or a momentary power interruption cause this. Most newer systems have lockouts that keep it from happening, but an old system probably would not. I would invest in a newer thermostat that has the compressor "lock out" that won't let the compressor start until 5 minutes after it last stops.

That makes sense. The 5 minute delay is to allow the pressure to bleed off so the compressor doesn't have to start up against the pressure. That could blow fuses for sure.

08-30-2005, 03:12 PM
And two fuses at once? I don't think so either, Tim.

Where did you get two fuses and a three phase motor? If there were only two fuses you would effectively single phase the motor and either burn it up or kick out the overloads.

Get it straight Tim.

You are aware that the five minutes are basically while the overloads cool down, right? Serves the purpose, but I don't think that was the original problem.

I still say the guy took him with the old fuses routine and he will experience more problems later.

My unit was doing almost the same thing a month ago. HVAC guy came and and said the motor in the fan was blown. He was just going to replace it but he checked my whole system and noticed the evaporator had a major leak. The unit is a original unit (house built in 89) and 10 SEER. He just recommended replacing the condenser, evaporator and coil and lineset, basically the whole unit. Put me back 2100 but man is it like a icebox in my house :)

Repair 1: bad blower capacitor and low on freon. Fixed it for 1 day.
Repair 2: bad blower moter Fixed it for 2 days.
Repair 3: bad run capacitor on compressor. Did not fix all the problems.
Repair 4: bad reversing valve (pending)

Hopefully, repiacing the reversing valve will let it run for another couple years.

Has the filter been changed... recently if ever? Usually if it "fixes itself" that means that lack of airflow over the condenser coil is causing it to freeze up. Once it thaws, it "fixes itself", until the cycle repeats.

That wouldn't keep the blower from operating. Pretty sure it's a motor/capacitor problem. Some models have an interlock so that if you have the cover off, it won't turn on.
