A common issue that requires furnace repair is the unit leaking. Common causes of these leakages include leaking condensation, malfunctioning heat exchangers, clogged furnace filters, and broken humidifiers.

It is critical to act fast and schedule professional furnace repair when you notice water leaking from your furnace. Here are some issues you can avoid by getting the problem resolved as soon as possible. 

1. Potential Damage to Internal Components

Water leaks may damage some of your furnace's internal components. This is especially true for electrical components. The water may, for example, completely damage your unit's circuit board, which would stop signal transmission and cause your furnace's complete breakdown. Without the signals, the furnace cannot initiate the heating procedure.

In light of such damage, furnace repair may be more extensive and expensive. If the damage is too severe, you will have to replace not just parts but the entire unit. 

2. Rusting of Parts

Exposure to moisture will cause rust buildup on various parts of your furnace. Left unattended, this rust can slowly progress and lead to cracks. Furnace repair for cracks may be pretty costly, and if the deterioration progresses further, a replacement may be on the books for your furnace. 

Additionally, cracks in your furnace, particularly the heat exchanger, may pose severe health risks for your household as carbon monoxide from your furnace may sip out through these cracks,

3. Electric Shock Risk

Any water pooling around electrical appliances exposes the members of your household to the risk of electric shock. When cleaning up the leaking water around your furnace, use an electric insulator such as plastic or wood. Also, ensure that you aren't barefoot during the cleanup or any time you operate the furnace.

What to Do?

Take care of water leaking from your furnace in the following easy steps.

1. Turn Off the Furnace

Turning off the furnace may prevent more water from leaking. You can do this by switching off the thermostat or the furnace switch.

2. Keep Things Dry

Exercise the precautions highlighted as you clean up the water around your furnace unit using napkins or towels. A wet vacuum should come in handy when dealing with a lot of water.

3. Call the Furnace Repair Experts

A qualified HVAC professional will troubleshoot your furnace and identify the exact cause of the leakage. The expert will then do what's necessary to fix the problem and prevent the same from happening again.

Don't Wait

Don't wait too long to take care of furnace repairs when you notice water leaking from your unit. It doesn't get better on its own over time, and you can avoid further damage to your furnace if you act fast.
