View Full Version : Too Much Coolant and Impact on Compressor
I have a 9 year old York heat pump with a failed compresssor. This unit had triggered a fault code reporting failure to generate over 90 degree heat, typically the result of too much coolant. The technician servicing my unit stated that York printed the wrong coolant information for this particular unit.
Would too much coolant shorten the life of the compressor? If so do you think York should assume some responsibility for the failed compressor?

An over charge will shorten the life of a compressor and your system will not function properly. I would not hold York responsible. Your installer is responsible for correct operation of your system and if there are factory issues, than it's up to that person to address them with the manufacturer. A professional tech would not just weigh in the amount of charge on the unit name plate and walk away.

At 9 years old. It has lived its life. Life of these units depends on if it was serviced regularly, the filter changed regularly, power surges and how much it ran (climate conditions). There are a lot of issues that can cause compressor failure, they aren't designed to run forever, otherwise, the manufacturers wouldn't make any money. I find it very amusing that you would think the manufacturer would pay for it, its 9 years old. They would surely get a good chuckle if you asked them. Its like wanting Ford to give you a new car if yours dies 9 years down the road.

W T F According to York, Trane and Carrier average heat pump compressor life is 22 years +, and my service experience reflects this seemingly optimistic outlook. York not only puts the refrigerant charge on the data tag, but puts the refrigerant in the unit..Give me the unit model and serial # and I"ll check for York service issues...

is the compressor shot? did the tech correct the mistake made by whoever didnt check the charge correctly, what is wrong after he was done.
sounds like the safety did its job and protected the compressor
Why aftr 9 years was it over charged was something done to the unit?

Whoa! Cart is in front of the horse..the fault code of failing to reach 90 degrees while in heat mode means nothing if the compressor is not running! Nor could it indicate excessive charge, couldn't even tell if run capacitor or contactor is functional...

How do you know the unit is over charged with freon? Did the hvac company pull out the freon and weigh it??
