All of the appliances in your home have an estimated lifespan. Some appliances may continue to work beyond their lifespan. This does not mean that their performance will be optimal and that they will provide the best energy efficiency. This is why some homeowners play by the rules and upgrade their appliances according to the manufacturer's recommendation. Furnaces are an example of an appliance that can last for many years. With proper maintenance, some furnaces will continue to operate. There might be subtle signs that a furnace replacement is needed, and those signs should not be ignored. The following points identify things that could suggest that it is time for a furnace replacement.
Cracks or Rust
Rust and cracks can happen when furnaces age. The metal can become compromised due to wear and tear. Rust is a sign that moisture has played a role in the deterioration. Cracks can allow moisture to seep into crevices and develop into rust. Rust makes metal become brittle. This means that the integrity of the furnace will be gradually compromised once rust starts to develop.
High Heating Costs
If your heating costs appear to be getting higher each month and there have not been any rate fluctuations with your provider, it could be related to your furnace failing. An inspection can yield the result of the nature of the spikes in the energy bill. If your furnace has not been serviced, an HVAC technician might recommend a tune-up. This might not correct the issue indicating that you will likely soon need a furnace replacement.
Soot and Debris Build-up
One of the primary reasons that this phenomenon happens is dirty air filters. However, debris can also build up when routine service appointments are missed. As part of the routine servicing, technicians clean furnace components and remove soot and debris. If these substances return before the end of the cold season, it is likely that the furnace is failing or that the air ducts are dirty.
Yellow Burner Flame
The flame in your furnace should maintain a blue hue. If you notice that the burner flame is yellow, you should cease operating the furnace and get it inspected. A yellow flame could be one of the first signs of a carbon monoxide leak. These leaks are toxic and can lead to serious illness or death.
An HVAC contractor is a good resource to use to understand more about the importance of getting a furnace upgrade in a timely manner. They can inspect furnaces and determine if older furnaces are safe to continue to operate. You can also depend on them to help you compare furnace models when you are ready to proceed with your furnace replacement.Share
