Summer is the time for your AC to shine. If your air conditioner is leaking water, you could find yourself in a big mess. Looking for symptoms of a leak at the start of things will save you time and money on repairs. Dark stains on your walls and ceilings, drips, weird smells and unusual humidity indicate an AC leak.
So, if your air conditioner is leaking water while it’s working overtime in this heat–it’s time to find the cause. Here are the top four culprits and how fix them:
AC units require some type of refrigerant, like Freon or Puron, to keep things cool. Typically a leak is the cause for low refrigerant. If this is the problem, it will require an HVAC professional or things will go from bad to worse. If the refrigerant is low, it could freeze up the evaporator coil causing water to leak when it melts or it could mess up pressure inside your unit. That leak is apparent by a tell-tale hissing or bubbling sound. If you don’t catch the leak in time, it will ruin your HVAC system and will need to be replaced.
A dirty air filter can also cause your AC to leak. A buildup of pet hair, dust and/or dirt could prevent airflow into your HVAC system’s evaporator coil. If air isn’t freely flowing, your evaporator coil will freeze. When that frozen condensation melts, it will cause water to leak out of your unit. That extra moisture could make your home prone to mold. Changing the filter is often overlooked by homeowners, but is a key step in maintaining the life of the HVAC system.
A blockage in your condensate drain line might be the cause of your AC leak. Your air conditioner also acts as a dehumidifier of sorts, pulling moisture out of the air inside your house. The condensate drain allows that moisture to drain out. Gunk like dust, dirt or even mold can build up in the process, causing a pretty nasty clog. If the block is bad enough, water could back up into your house, causing water damage or flooding. Here’s how to fix it:
If it’s more than a dozen or so years old, you might need to replace the drain pan. Since some drain pans are made of metal, they are prone to rusting and corrosion.
Installing a float switch is an insurance policy of sorts. It cost less than a few hundred bucks for a professional to install, but it could save you thousands in home repairs in the long run. A float switch is a mechanism that will shut off your system if your drain pan has excess water. So, if you have a leak caused by something like a clogged drain line or heavy condensation, the float switch will detect the extra water and shut down your HVAC system before any major damage is done.
If you can’t find the leak or if it reoccurs, it’s time to call in a professional HVAC company to fix your AC unit. The longer you wait, the more prone you are to water damage or damage to the AC itself.
