How To Prevent Frozen Condensate Lines

With temperatures dropping, condensate drain lines have a higher chance of freezing. When that happens, most HVAC systems are designed to shut off completely, leaving homeowners scrambling for a solution. In reality, a major repair may not be necessary as thawing the frozen drain lines should fix the issue.

 

Are some systems more likely to experience this issue?

Yes! High-efficiency furnaces, which are the way to go if you want to significantly reduce your energy bill. Because these systems are more efficient in heating your home, they produce more condensation. More condensation means more water (up to 5-6 gallons each day). Add in the extreme temperatures winter brings and you’ve got yourself a problem if you’re not prepared.

 

Can you prevent HVAC condensate drain lines from freezing?

The short answer is yes. Depending on the conditions, there are a few ways homeowners can prevent this situation from happening. That doesn’t mean the condensate lines are guaranteed to never freeze though. Here are a few suggestions:

  • Insulate drain with a weatherproof material
  • Use Ice Melt underneath the drain line exit point
  • Install heat tape around the exposed pipe

Be sure to periodically check on the exit point of your condensate line to ensure it continues to draining properly. And don’t underestimate the importance of regular maintenance!
