9 Year Old York Central Ac
We have zone heating/ac in our 9 year old home. The York Hvac unit for the upstairs worked ok for about 5 years but has had repair service every year since.
Inside A coil freeze ups, capacitor changes, ac unit fan motor replaced, several pounds of coolant. We've decided to replace the ac unit after spending so much on repairs. The central ac unit was not very reliable in my opinion. We live in St Louis.
Since you have had to add several pounds of coolant, the freezing coil is likely a result of being low on refrigerant. Being low an refrigerant is seldom a problem with the equipment, but an installation problem. Open fan run capacitors are a common problem with PSC motors.
Replacing an indoor blower motor after 5 years is not too bad as the motor runs in when you are heating as well as cooling.
The unit may not be responsible for the need to add refrigerant. Refrigerant is not “used up” nor does it wear out. A leak free system will never need refrigerant added. Most leaks are outside the factory equipment in the piping that is installed by the local contractor not the equipment manufacturer. Many times the brand is condemned when the problem is with the installation.
Tip to homeowners, if the technician tells you he has to add “Freon”, ask him if he fixed the leak. If you are low on refrigerant you have a leak in the system.
