The most common issues faced with HVAC systems are weak airflow, poor smells, loud noises, hiked utility, uneven temperature, etc. One furnace issue that needs our immediate attention is water leakage.

The issue might not require a technician for furnace repair in Tulare but it does need an inspection. You should inspect the unit after noticing the leakage to ensure whether we need a professional.

Seven reasons for leakage in the furnace

Most furnace leakage issues result from clogging and excessive dirt in the furnace unit, while damaged components can also be responsible for this. Seven reasons can result in leakage in the furnace. These reasons are:

Damaged drip pan

The excessive water from the furnace drips into the drip pan that throws this water outside through the drain lines, but if there is any crack in the drip pan, the water will not pass outside. The water will start dripping slowly from the crack and result in leakage.

Faulty humidifier

Air conditioning units are equipped with a humidifier to absorb the excess humidity from the room, but during winter, we need humidity to cope with the extreme dryness. If the humidifier attached to the HVAC is loose or damaged, it will cause leakage. Contact the technician for heating services in Tulare to get the broken humidifier replaced on time.

Clogged drainage

The drain lines are responsible for throwing out dirty or wastewater from our house. If the drain lines get clogged due to dirt accumulation, the water will not pass through them. Therefore, you will notice liquid near or around our furnace due to clogging in the drain lines.

Blocked drain pump

Drain pumps collect all the wastewater from the furnace for drainage. If the drain pumps are blocked, they will not function properly, resulting in a leaking furnace.

A build-up of ice on coils

Frozen coils are a common issue during winter. If you do not melt the ice, too much build-up of ice on the coil will cause leakage.

Clogged PVC drain pipe

PVC drain pipes circulate the condensate to the drain lines. You will notice a leakage in your furnace if the PVC drainage is clogged or damaged.

The heat exchanger issue

The heat exchanger produces and circulates heat through gas or other sources. It will lead to condensation. However, condensation is a part of the process; if it is balanced, there will be no leakage.

If the heat exchanger is not working accurately, the condensation can be too much and more than the capacity of the PVC drain lines. This excessive condensation will result in the furnace leaking on the floor.
