Signs of Furnace Failure

When a furnace fails, it loses efficiency and reflects on the heating bills since it has to run more frequently

The furnace is a part of AC systems and can malfunction without warning sometimes. There are also instances when the furnace doesn't perform to its full capacity, which can be a nightmare for homeowners. It gets even worse if it happens in the middle of winter.

Hence, it's important to know some signs of furnace failure for timely intervention. Note that paying attention to the system helps detect issues early.

Illnesses among members of the household

When a furnace fails, cold and flu-like symptoms may be common among the home's residents. This is mainly due to carbon monoxide leaks within the gas heater. Another possible reason is poor exhaust ventilation. Carbon monoxide buildup can have significant health effects even in small doses. Higher doses are deadly, so consider installing a carbon monoxide detector. Getting professional installation and regular maintenance can help avert this issue.

Old furnace

While some furnaces are durable, as they age, failure is imminent. It's important to check the heating system's age by looking at its label. Talk to the experts if you can't tell the furnace's age. While the average age is 15 to 20 years, some models can last longer than that. Older furnaces may keep breaking down constantly.

High bills

When a furnace fails, it loses efficiency and reflects on the heating bills since it has to run more frequently. It demands more fuel without enough heat production. The furnace runs without making the household warm enough. In this case, consider a tune-up or a complete replacement.

Strange noises

Noise can indicate furnace failure as well. If one notices any noises, it's better to act early. A furnace that hasn't lived its full life is better repaired than replaced. But let professionals handle such issues.

Change in the pilot flame color

A gas furnace should have a bright, vibrant blue flame. If the flame is wavy, weak, and flickering, it could indicate unburned gas. The changes in the pilot light color may arise from carbon monoxide failing to exit the system.

If the flame is yellow, it indicates partially blacked or dirty systems. In such an instance, contact a professional contractor for assistance.

Soot

If a furnace is incorrectly installed, it generates soot. However, soot may also indicate that the system is aging and requires a replacement since it's a failure indicator.

Inefficient temperature control

The modern thermostats have new features to save costs and offer more comfort. If some of the parts of the home are cold while others are warm, it points toward inefficient temperature control. A replacement may best remedy this.

Consult with professionals

Proper installation, maintenance, and repair of any home AC system should be left to a qualified technician. Homeowners should make consultations if in doubt about their furnace. A professional can assess and recommend whether to repair or replace the system.
