10 Signs To Replace Your Furnace & How Often To Replace Your Filter

When it comes to keeping your home warm and cozy during the chilly months, your furnace plays a vital role. Over time, like all appliances, furnaces can wear out and become less efficient. Regular maintenance is key to extending the life of your heating system, but there will come a time when you need to replace it. In this blog, we’ll explore the signs that indicate your furnace needs replacing and how often you should replace its filter to ensure optimal performance.

Signs Your Furnace Needs to be Replaced

Age of the Furnace

One of the most important factors to consider is the age of your furnace. If it’s over 15-20 years old, it’s probably time to think about a replacement. Furnaces become less efficient and reliable as they age, leading to increased energy bills and more frequent breakdowns.

High Energy Bills

A sudden spike in your heating bills may be a sign that your furnace is working harder to produce the same amount of heat. Newer, more energy-efficient models can help you save on energy costs.

Frequent Repairs

If you find yourself calling for repairs more often, it’s a clear indication that your furnace is reaching the end of its life. Continual repairs can quickly become costly.

Inconsistent Heating

If some rooms are too warm, while others are too cold, it could be a sign of an aging furnace that can no longer distribute heat evenly.

Loud or Unusual Noises

Strange noises, such as banging, squealing, or popping, can be signs of mechanical problems within the furnace. These issues can become more frequent as the furnace nears the end of its lifespan.

Yellow Flame

A healthy furnace flame is typically blue. If you notice a yellow or flickering flame, it could indicate a carbon monoxide issue or incomplete combustion, which is a serious safety concern.

Visible Rust or Cracks

Visible signs of wear and tear, like rust or cracks in the furnace, can be red flags that the unit is no longer safe or efficient.

Excessive Dust or Soot

If you notice an unusual amount of dust or soot around your furnace or in the air, it may be a sign of poor combustion and a need for replacement.

Uneven Temperature in the House

If you find it difficult to maintain a comfortable temperature throughout your home, it might be due to an inefficient furnace.

Carbon Monoxide Detector Alarms

If your carbon monoxide detector goes off, it’s a critical sign that your furnace is malfunctioning, and it needs immediate attention.

To ensure your furnace is in top condition, regular maintenance and inspections are essential. By addressing problems early, you can extend the life of your furnace and reduce the risk of sudden breakdowns. However, if you notice any of these signs, it’s time to consider replacing your furnace for safety, efficiency, and cost-effectiveness.

How Often to Replace Your Furnace Filter

In addition to knowing when to replace your furnace, it’s crucial to understand how often to replace the furnace filter. A clean filter ensures that your furnace operates efficiently and keeps the air quality in your home at its best. Here are some guidelines for maintaining your furnace filter:

Every 90 Days

The general recommendation is to replace your furnace filter at least every 90 days. This ensures that your furnace works optimally, as a clogged filter can reduce airflow and force your furnace to work harder.

If You Have Pets

If you have pets, consider changing your filter more frequently. Pet dander and hair can quickly clog filters, reducing their efficiency. Every 60 days is a good rule of thumb for pet owners.

Allergy or Respiratory Issues

If anyone in your household suffers from allergies or respiratory issues, you should replace the filter every 30-45 days to maintain excellent indoor air quality.

Check Monthly

It’s a good practice to check your filter monthly, especially during peak heating or cooling seasons. If it appears dirty or clogged, replace it right away to prevent strain on your furnace.

By maintaining a clean filter, you not only ensure your furnace runs efficiently but also improve your home’s air quality. Regular filter replacement can also extend the lifespan of your furnace by reducing the wear and tear caused by restricted airflow.
