What is the most common source of refrigerant leaks?

The most common cause of AC freon leaks is likely erosion of the metal over time due to formic acid or formaldehyde corrosion. Small holes are formed when the acid eats away at the metal and the unit eventually releases freon.

How do I find a leak in my Freon line?

One of the oldest ways to detect a leak is by using the bubble method. To do this, apply a soap solution to areas where you suspect a leak has occurred with a brush squeeze bottle or dauber. Typically, any escaping refrigerant produces bubbles at the leak points.

How long does Freon last with a leak?

Refrigerant Leaks

If a leak is present, the refrigerant will simply leak out as soon as it is replaced. So, the coolant will last no more than a few weeks to a few months, depending on the severity of the leak. There may also be more than one leak, which could cause the refrigerant to disappear sooner.

Can leaking Freon cause headaches?

Symptoms can vary depending on the extent of the Freon exposure, but even a small amount of exposure can cause serious symptoms in humans. Mild symptoms of Freon exposure include excitability, dizziness, changes in heart rate and headaches.

How often does Freon need to be added to AC?

Never. You shouldn't have to “add” refrigerant to a central air conditioner because it doesn't “use up” refrigerant. The only reason you would ever need to recharge (that is, add refrigerant to) your A/C is if you have a leak; once the leak is fixed, the problem should be solved.

How often does home AC need recharged?

What happens if Freon leaks in your house?

The loss of refrigerant can cause your system to cool inefficiently. Your system may struggle to produce adequate air conditioning, preventing your home from reaching the desired set temperature. This not only causes your system to work harder, but it can also increase your monthly energy bills.

How long does Freon last in HVAC?

Freon (which is really just a particular brand of refrigerant) lasts forever. It's not like gas in car; it does not get “used up.” You see, your air conditioner's refrigerant system is a “closed/sealed system,” meaning that it does not allow refrigerant to escape in any way.

What causes Freon leaks in home air conditioner?

Factors that can contribute to freon leaks include improper installation, factory defects, as well as damage or wear-and-tear on your AC system. So even a brand new air conditioning system could have a freon leak if it's not properly installed.

How long should an AC unit last?

While every unit is different, and every homeowner has a different understanding of when their central air conditioner is broken beyond repair, it's fair to say that, with proper maintenance and care, you can expect a good 15 to 20 years of cooling from a new high efficiency air conditioning system.
