Top Furnace Problems That Homeowners Experience

Your heating and air conditioning equipment may sometimes fail to perform as expected. One of the most common HVAC failure points is the furnace. When your furnace fails, the entire HVAC unit may be rendered dysfunctional as no hot air will be blown to warm your home. It helps to understand some of the most common failure points of a heater.

Noisy Unit

Sometimes, a furnace will produce some clicking noise when running. This is an indication of mechanical malfunction in various points. One of the likely culprits is a loose inducer or worn-out motor bearings. It is particularly common in gas-powered furnaces where the motor-powered fan becomes loose, thereby producing a clicking noise when turning. Having the unit inspected as quickly as possible will ensure that the problem is fixed.

Furnace Blowing Cold Air

The furnace is a crucial component that provides the warm air for your HVAC system. Sometimes, it may fail by blowing cold air, even when the thermostat is set to high temperatures. One of the likely causes of this failure is an issue with the pilot light, thermostat settings, or air filters. A dirty and clogged air filter will impair airflow in the system, which leads to a shutdown of the heater. The thermostat may also have a poor connection to your furnace, implying that any temperature adjustment made is not registered correctly.

Leaking Water

It is not uncommon to find a heater that is leaking water, especially high-efficiency gas furnaces that use a floor drain to eliminate condensation. A leak in one of the cooling pipes connected to the unit could cause water to accumulate and ultimately affect other parts of the HVAC system. The built-in humidifier could also be a source of the leak, especially if it is clogged.
