Help! My Air Conditioner is Leaking

Air Conditioning Technician

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 Walker Heating & Air Conditioning in Woodbridge, VA 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 Woodbridge, VA and surrounding areas, call us at (703) 483-2400.

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. Walker Heating & Air Conditioning 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 Woodbridge, VA 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.

I finally called Walker Heating & Air, and Kevin was out the following day. He provided me with the best options without trying to oversell any extra services or equipment, which was a huge change from the previous company. "
