You rely on your AC unit for months at a time during the hottest times of the year, so when these units begin to underperform or break down, it's a headache. Being able to spot the warning signs will let you know when to reach out to a professional for AC repair before the situation worsens. Here are a few of the most obvious signs of an AC refrigerant leak. 

How to Know When Your AC Has a Refrigerant Leak

1. Electric Bills Increase

If your electric bills start to increase without a corresponding increase in AC usage, it could indicate an issue with your system's refrigerant. A unit that's leaking refrigerant will need to work much harder to keep a home cool, which will be reflected in your monthly energy bills. 

2. Unit Emits Loud Hissing Noises 

AC units should be relatively quiet, humming along as they release cool air into a home. If you notice your unit sounds louder and clunkier or is hissing, this is a sign the unit is leaking refrigerant. Cracks in the coils may be releasing refrigerant and making the strange noises. 

3. Vents Release Warm Air

When you've turned on your AC unit and allowed it to run for a few minutes, it should begin to release consistently cold air. If your vents are emitting warm air long, that's likely because the system is low on or leaking refrigerant.
