Lennox 10acb224-11p


I have a lennox ac that 10 years old just had a service person come out an check it out an do maint he inform me that the compressor was getting ready to fail an that he recommend that we replace the whole system furnace an all he sad he would not recomend replaceing the compressor in such an older unit that it was basiclly a builders grade ac unit this same tech was out to service or furnace when it went out last winter an tried to sell me a electric air filter for the furnace what im wondering is it common for this ac model to have compressor problems

Hard to predict when a compressor will fail. Unless its been giving you trouble.

That tech may be on commission based pay.

Did he say why he thinks its ready to fail. And what needs to be done to prevent the next compressor/new system from having an early compressor failure. Compressors last a lot longer then 10 years. On systems that are installed right.

Thats the thing. Those readings are hard for "you" as a customer to know what they mean. They could have been normal readings.

No real way he can know for sure that on the first 90 day it will fail.

I'd get a second opinion.

And just ask them for a service check. if its really having trouble. Another company will tell you the same basic thing.

Weather they show you the readings or not. Tell them you want them written down on the invoice.
And if the second company says its fine. Call the service manager, or owner of the first company, and report that tech.

Get yourself a meat or cooking thermometer. Make a small hole in the plenum just past the AC coil. Check the temperature there with the unit running after 5-10 minutes. Subtract it from the house temp. If the difference is between 16-20 degF you probably are okay as that is the normal temp drop. That is a pretty good unit and the compressor should last at least 15 yrs if it has been maintained properly. Where do you live?

The 10acb was a builder grade unit but is not prone to early compressor failure. They were cheaper due to a short warranty and a few componets not on them that came with the premium line.
