By now, you probably understand that a furnace can develop different kinds of problems. The greatest concern is to know how to identify such problems. Your furnace may seem to be working properly but in the eyes of a professional HVAC technician, things might be totally different. This is therefore your best moment to discover common furnace warning signs that call for professional intervention.

Unusual Noises

A furnace that is working properly should be silent. A noisy one needs immediate inspection because it might be a sign of something wrong inside it. When some problems such as noise are ignored, they tend to develop into something bigger and more expensive to fix.

Watch out for Leaking Gas

A furnace that leaks gas into the air should be repaired or replaced immediately. The leaking gas can cause respiratory complications, allergies or even fires in your home. When you turn on the furnace and realize the smell of gas in the air, you need to look for a professional HVAC technician right away.

Consider the Age

As your furnace gets older, it tends to become less efficient. This happens to so many machines and it might require repair, replacement or routine servicing depending on its current condition. An old furnace is more likely to leak especially if it has not been serviced for a very long time.

A Defective Thermostat

The thermostat plays a crucial role in controlling the amount of heat inside the house. If this feature stops functioning properly, then you have every reason to look for immediate furnace inspection. Some characteristics such as intermittent heat or difficulty in switching it or off are enough to prove that the furnace is not working properly.

Unusual Yellow or Orange Flame

A good furnace should release a strong blue flame but not yellow or orange. If your furnace releases any other flame than blue, then it needs to be serviced. A yellow or orange flame might be a result of obstructed airflow and this is one of things a professional technician can help fix.
