Geothermal Heat Pump with refrigerant Leak

16 years ago

A GHP is leaking refrigerant. A HVAC tech recharged the system and included a dye pack to look for the leak. He intended to leave it running for 30 days. However the refrigerant had leaked out in one week. HVAC tech spent 4 hours trying to find the dye and could not. Then pressurised the coax, compressor, and condenser coil but claims they all held pressure. His recommendation, new system!

First anyone have any comments or suggestions.

Second, is it possible that the refrigerent leaked via the coax into the horizontal water loop?

Is leaky refrigerant the problem?

https://www.minisplitairconditioningsystem.org/

You likely won’t know until you call in an expert. There are some symptoms that could indicate your air conditioner is low on refrigerant, and it is, in fact, a common problem. Here are some of the possible signs.

Temperatures higher than expected

Only warm air comes through the vents

Frozen coils inside of the system

High energy bills and poor AC performance

However, you should know that all of these signs could easily apply to another problem. Not getting enough cool air? Maybe a fan motor is broken or failing. Frozen evaporator coils? It could be a dirty air filter. High energy bills and poor cooling performance? Well that could be any number of things!

Don’t jump to conclusions until you reach out to a technician. You may think that you can wait to get refrigerant added to a system, but this isn’t the case! Waiting too long can lead to a number of problems, so…

Don’t wait to call a technician

When you wait to call in a technician about problems in your air conditioner, you risk even larger problems affecting your comfort, your bills, and your stress levels.

Refrigerant could leak into the compressor causing irreparable damage, a common reason to replace an air conditioner.

The indoor coil may freeze more easily, and water could leak into your home as a result.

Enough refrigerant could leak that motors and pumps start to wear out faster than they should.

Your air conditioner was designed to use a certain amount of refrigerant with each cycle. Any lack could potentially cause a huge problem, which brings us to our next point…

Refrigerant is not supposed to leak!

Finally, we want to make sure you know that refrigerant was never intended to leave your system in any way! Air conditioners depend on refrigerant, not as fuel but as a heat transferrer. Heat cannot leave your home unless there is always a level amount of refrigerant, which is why refrigerant lines are built tough. Any drop in levels typically indicates a leak!
