Help! My Air Conditioner is Leaking

AC Repair Anderson SC

The last thing you want to experience on a hot summer day is your AC leaking water all over your floor. Not only is it a huge inconvenience and discomfort, it’s a clear sign your air conditioner needs attention. The good news is that not all issues have expensive repair solutions – some are simple and easy to diagnose yourself. For those tricky situations you can’t diagnose yourself, our HVAC techs at AirOne Heating & Air in Anderson, SC are ready to help.

Let’s explore some of the reasons your AC may be leaking.

Why is my AC leaking?

Before we start exploring the possible reasons, let’s establish the basics. Your air conditioner should never leak water. If it does, it’s important to turn your thermostat off immediately. Leaving your AC on and running can cause further damage.

1.    Dirty Air Filter

A dirty air filter can restrict air flow and freeze the coils. As the ice melts, the AC leaks. If it’s been a while since you’ve replaced your air filter, it’s time to do so. Depending on the season, air filters should be changed every 1-3 months. If the leak persists after the filter is changed, your AC leak is likely caused by something else.

2.    Clogged Drain Line

The most common cause of water leaking from an air conditioner is a clogged condensation drain. Your drain like can get clogged with dirt, sludge, mold or rust, blocking the condensation from draining properly and causing an AC leak. There are some DIY methods to unclogging your AC drain line but the most reliable way to fix the problem is to call an HVAC professional. If you have a clogged AC drain line in Anderson, SC and surrounding areas, call us at (864) 617-6883.

3.    Damaged Drain Pan

If your AC is 10 years or older, your drain pan may be damaged or rusted, allowing water to fall right through. While you can replace the pan, it may be time to consider getting a new AC system. There are many benefits to replacing an old AC unit including energy savings and lower utility bills. AirOne Heating & Air provides AC installation services to ensure you get the right unit for your home and family.

4.    Not Enough Refrigerant

Refrigerant problems can make your coils freeze up, causing a leak as they thaw. You may notice signs you’re low on refrigerant like a hissing or bubbling sound or insufficient cooling when your AC is on.

Our HVAC techs in Anderson, SC can diagnose and fix your AC leak, keeping you cool and comfortable all summer long. If your AC doesn’t have a float switch, ask us about installing one. A float switch will automatically shut down your unit if water is in the pan, protecting your system from further damage.

We called AirOne to schedule a service on our system. Dalton Reynolds called to let us know what time he would be arriving. It was raining when he got there, but that did not phase his attitude one bit. Very kind, courteous and knowledgeable young man. He completed the inspection & service then answered several questions we had. He then explained one small issue he came across and told us our options. We are extremely satisfied w/ the way company handled our service from the initial call til completion. Awesome price too. I highly recommend this company.

This company is the best! We just moved to the area and our heat went out right as it was getting cold. I called on a Friday morning and was told their first availability was Monday. But, by mid-morning they called and said they could come out that afternoon. That is great service! They go out of their way to take care of their customers. Chris was excellent and explained everything that was going on and what our options were. I will definitely use them again!!

Thanks to Air One and to Josh for coming out on a Saturday morning to repair my heat. Josh was very polite and personable. It turned out to be a simple fix but he took the time to explain the procedure. I know it’s just another raving review but Josh and the Air One team are worth it. Thanks again to Josh and the team
