Carrier Home Ait Cond. System Question

Page 1 of 2  

Our Carrier home air cond. system has started acting up. It is doing the following.
1. I will run for about and hour or so and stop. 2. Service tech comes out and checks freon levels are good and finds a switch inside the unit that was blackend. He replaces the switch and I fire it up. Service guys ssys do not turn off anyhting and call him back it it stops. It runs about 2 hours and stops. 3. service guy comes back out and removes cover over compressor and finds that the cap over the wires going into the compressor is broken from heat. The power is off to the unit. While standing there we hear a poping noise and the service guy says it will run now. He says the compressor has a thermal switch on it that will cut it off if it gets to hot. He plugs the power plug back in and tells me to fire it up. I do and the units come back to life. He then takes down the serial number from my units and tells me they will have to call Carrier tech support and ask them what they think it is. Service thinks that there could be a bad filter or something clogged on the system and he is not sure. He says they will get with me on Monday.
He said that if the compressor is bad it is almost has easy to put a new unit in and be done with it. He said a new compressor can cost upwards or 800.00 to 900.00 or more.
Needless to say all this is going on Friday and Saturday with temps in the 90's. We went and purchased two windows units to atleat keep us cool until we get it fixed.
I know this was long winded but I wnated to get as much info out as I could.
So based on my problem, does anyone have any ideas on this?
Thanks for your time.
Funny thing was when I was a kid I almost went into this field.

Like Paul said... find somebody who knows WTF they are doing.

$800 - $900 is half price... what corners is he cutting?? A new system can run from $4000 - $25000.

Well, Steve. Sounds like it's time for my favorite diagnosis, you think?

Ask the company to send out the 9.00 per hour tech.....not the 7.00 per hr tech

Burnt parts, tripping off with the overload protector. I'd sure say that the outside unit isn't properly releasing the heat. Time for my favorite diagnosis. Yeah, the nine dollar an hour tech might find out what's wrong.

Buy a large can of smoke and replace that, which has gotten out of the unit.

Sounds to me like that compressor has some shorted windings causing it to draw too much current resulting in burnt wires before the internal overload can open. Average lifespan of the unit is 12 years upward.. Average warranty is 10 years. If that system has burned or has acidic oil and cooling gas.. It will require a good clean up it the compressor is replaced. That is time consuming and expensive.. Plus additional filters need to be installed. If such is the case. Replace the entire system with a more efficient on with the newer so-call environment friendly Gases. Funny thing..When I was a kid, I damn near didn't! ;-p

I was thinking dirty condensor. Retains the heat. Drives the head pressure and amperage up. My first thought is to chemical clean the condensor, so it can release heat. Also has the advantage of being a much easier and cheaper fix than compressor change out.

Well thnaks for all the bantering. Today I will know more and I will post the findigns here for you all to see. Since the I have the furance in my garage and the heat exchanger/heat pump is at the oppsite end of the house. You would think that I would get a small break as all the duc work is in and they would not have to intall that plus the eletric is already in place.
Thanks again.

From what you've written, the outdoor unit is packed with dust. The tech should take the fan off the top. Spray some water based chemical on. Wait a while, rinse with the garden hose. It will take two or three or four applications of chemical (wait three to five minutes before rinsing, to let the stuff work).
Please let us know what happens.

The tech called and said he spoke with the carrier people. They said it is maybe a bad bearing in the compressor. He said I need a new system. 900.00 for new compressor plus install fees if I wnat to go that route or I can go with a new system by york for $2800.00.+

From what I know of AC, the only way to know it's a bad berring is to clean the condensor. Let it dry thoroughly. And then check a bunch of temperatures, amperage, and pressures. If you just jump to the "bad berring" then you might end up yanking out some perfectly good equipment with minor problems.
Anyhow, let me know. The gas to cinci is cheaper than a new compressor. Right up the road is a restaurant named Young's which serves fairly good food.

Is there anything as a home owner I can do as far as the cleaning of the unit as the other guy said? I do not see where there is dust in anything other than the normal dirt and grim from it setting outside.
I think I will call the carrier people and have them come out and have a look at it...

You need to call a *COMPETENT*, licensed, insured, professionally trained, HVAC technician to come correctly diagnose and correct the problem with the system. No he is not gonna be the cheapest price, but then knowledge and quality doesn't come cheap. Tell that other "sales-nition" to hit the road and find another sucker.
