Common Signs That Your Home AC Needs More Refrigerant

When it’s hot outside and you’re looking for a bit of relief, nothing says “cool” like the air conditioner (AC) that you have inside your home. But when it comes to what it needs, maintenance-wise, have you ever wondered what the signs are that it needs to have more refrigerant in it?

If so, this is a great article to check out. That’s because it’s going to share with you five of the most common signs that it’s time to pour a bit more coolant inside of your AC so that it can work efficiently all summer long.

Your AC is leaking. There are basically two ways to know if your AC is leaking refrigerant. One is if you literally see some refrigerant on the floor – another is by listening to how it runs. If you notice that it tends to start and stop frequently, this is a pretty reliable sign that somewhere within the unit, there is a leak.

Your AC seems to be blowing warm air. When you turn your AC on and it’s set to a cool temperature, it shouldn’t take a long period of time before cold air starts blowing into the various rooms of your house. So, if it does take more than a couple of minutes, this could also indicate that your AC is in need of some more refrigerant. Speaking of warm air, if your unit has been on for over 30 minutes and still no cold air has come out, that’s a definite sign that some refrigerant is missing.

Your AC has ice on the outside of its unit. Something that is very abnormal for an AC unit is if the outside part of it has ice on it during the summertime. When this happens, it’s also a clear indication that there is low refrigerant – so low that ice has begun to form as a direct result.

Your AC hasn’t been serviced in a while. One of the best ways to keep your AC in top condition is to have it serviced by a professional HVAC technician. They can check for leaks, clean your ducts, change your filters, and also make sure that your refrigerant is at the right level. If you can’t remember the last time that you’ve had a technician over to inspect your unit, honestly, that’s too long. It’s a more subtle sign that you may need some more refrigerant, but it’s still a relevant one.

Your energy bills are higher than usual. Have you gone out to the mailbox to get your electricity bill and noticed that it’s a lot higher than you expected it to be? If so, it could be because of one of two things: One could be because you are not doing things like providing adequate sealing and insulation in your home (especially when it comes to your attic, windows or doors) or it’s because the refrigerant in your AC is so low that your unit is working overtime. You can check to see if your house needs sealing and/or insulation by conducting an energy audit. You can learn more about energy audits by going to Energy.gov and putting “DIY energy audit” in the search field. You can confirm if your energy bills are escalating due to low refrigerant by having a technician come over to take a look.
