What Does a Leaky Furnace Mean?
Posted On: January 26, 2025
A leaky furnace can indicate several issues, depending on the source and type of the leak. Here’s a breakdown of what it could mean:
1. Condensation Leaks
- Reason: High-efficiency furnaces produce condensation as a byproduct of their operation. If the condensation drainage system is clogged or damaged, water can leak from the furnace.
- Signs: Water pooling around the base of the furnace.
- Solution: Inspect and clear the drainage system or repair the condensate pump.
2. Humidifier Leaks
- Reason: Some furnaces are connected to a whole-house humidifier. If the humidifier malfunctions or its water line becomes clogged, it may leak.
- Signs: Water near the humidifier attachment.
- Solution: Check the humidifier and repair or replace faulty components.
3. Ventilation Problems
- Reason: Blocked or improperly installed vents can cause condensation to accumulate and leak around the furnace.
- Signs: Water around the furnace or near exhaust vents.
- Solution: Ensure vents are clear and correctly installed.
4. Cracked Heat Exchanger
- Reason: A cracked heat exchanger can cause water vapor to leak, especially in older furnaces. This is a serious issue as it may also lead to carbon monoxide leaks.
- Signs: Visible cracks, water vapor leaks, or unusual furnace noises.
- Solution: Shut off the furnace and contact a professional immediately.
5. Air Conditioner Coil Leaks
- Reason: If your HVAC system shares a furnace and air conditioner, a clogged or damaged AC condensate drain pan can cause water to leak near the furnace.
- Signs: Water around the furnace when the AC is running.
- Solution: Inspect and repair the AC drainage system.
6. Frozen Pipes
- Reason: In colder climates, pipes near or connected to the furnace may freeze and burst, leading to leaks.
- Signs: Leaks coinciding with extremely cold temperatures.
- Solution: Insulate pipes and repair any breaks.
What to Do If Your Furnace Is Leaking
- Turn Off the Furnace: Shut off the power to prevent electrical hazards.
- Clean Up the Water: Remove pooled water to avoid damage to surrounding areas.
- Inspect the Source: Check for visible issues with condensate lines, humidifiers, or vents.
- Call a Professional: If the issue isn’t obvious or easily fixed, contact an HVAC technician to diagnose and repair the problem.
A leaky furnace may seem minor but can indicate serious underlying issues. Addressing it promptly ensures your system runs efficiently and safely.

Our furnace was rattling, as soon as we put our air conditioner on this past week. We had researched looking for a company that was Registered with Better Business Bureau, and this company TwinTech, had A+ Rating. Scott, was immediately helpful via text/phone and sent his technician as soon as he was able...Mitchell/technician provided great professional service. Thank you TwinTech.

I contacted various companies when looking to install a new furnace and I found Twintech to be transparent with their communication and approach. They had options to suit my various requirements and the price vs quality was very good. The after installation communication was also very good and they answered all queries I had.

All winter I have had an issue with very little heat reaching the 2nd floor of our home. After this past winter ended I decided to look into this. I found Twintech Heating and Cooling on line and started the process. After explaining my problem I had a call form Twintech and the tech came out and walked through things with me. The problem was the heating vent pipe had been dropped down in size by someone years ago causing little heat reaching the 2nd floor. Further into checking out the older furnace and AC they found a few things not properly installed by the last install of the old furnace and also that the AC was on it's last legs. I asked for a quote and waited a few days and we decided to go ahead with Twintech. They called a few days before to set up an installation time and date. The day of the install the guys were a half hour early which was a plus. The day of the install was great, the guys worked away removing the old furnace and AC.After which they installed the new furnace and AC. After they cleaned up the basement with all their tools and scrap metal etc. they came back inside to walk thru what they did. They also tested both the furnace and cooling systems to make sure everything worked and I the customer was happy. I now have heat on the 2nd floor for next winter. The guys from Twin tech were very professional. Their work habits and knowledge of the job was excellent. Their workmanship was just excellent, it was just up there with my standards as a homeowner. I am very pleased to have chosen Twintech for my new furnace and AC.. If I had to rate this experience with Twintech this company is a 10 in my books.Product,workmanship and customer care says it all.
