How can you tell if your HVAC system is leaking?
And what are the options for fixing each?
There are three kinds of leaks in an HVAC system, and none of them are good.
If you ever see water around your home’s indoor a/c unit, it’s a sign that something is either dripping, leaking, or not draining. Three main reasons an a/c system leaks are if there’s a crack or hole in the overflow drain pan, the air filter is clogged with dirt, or the condensate line is plugged up.
The water may also be caused by a cracked condensate pan, trap, or drain, a damaged condensate pump, dry-rotted, cracked or kinked furnace tubing or condensate parts, or the drain line has moved and is no longer pitched downward.
Refrigerant (such as Freon)
Refrigeration systems are sealed and don’t use up refrigerant. So if you had a refrigerant leak, recharged the system with additional refrigerant, but fixed nothing, you still have a leak. A system running low or near empty on refrigerant is quite harmful to your compressor and could damage the entire system.
There are many signs your system could be experiencing a refrigerant leak, including if your house takes longer than normal to cool off or the supply ducts/registers are blowing hot air even when your a/c is running and your thermostat is set to “cool.” We discuss in more detail the problems and solutions that leaking refrigerant can cause in our blog, “Should I Have to Add Refrigerant to My System Every Year?”
If your system is leaking air, however, most air leaks can be traced to the equipment or ductwork, which can easily be found and repaired. Since ducts are often damaged when people come in contact with them, especially during home repairs, major or minor leaks can occur. Any major damage may require replacement of sections of the ductwork, but minor damage might be able to be sealed using sealant or metal tape. Leaky ducts can waste hundreds of dollars each year and should be repaired or replaced as soon as possible.
Bottom line, your HVAC unit should not be leaking water, refrigerant, or air. Just call John’s so we can test your system to see where any problems are. We’ll give you options so your unit or its parts can be repaired or replaced and you can get back to enjoying the comfort of your own home again.
