Go Back To Previous PageIf you’re considering a furnace replacement, you’re not alone. Many homeowners eventually face the decision to replace their furnaces. Whether your furnace is aging or showing signs of
wear, it’s essential to understand the costs involved, how often to replace the filter, and when it’s time to make the change. In this guide, we’ll cover the key points to help you make an informed decision without the stress of unexpected costs.
How Much Does It Cost to Replace a Furnace?
Replacing a furnace is a significant investment, and the costs can vary depending on several factors.
On average, the cost to replace a furnace ranges from $2,000 to $7,000. The total cost depends on the type of furnace you choose, the size of your home, and the complexity of the installation. For instance:
- Electric Furnaces: These are usually the most affordable to replace, typically ranging from $2,000 to $4,000 for the unit and installation.
- Natural Gas Furnaces: A more common option, these typically cost between $3,000 and $7,000, with larger homes and more complex installations pushing the price higher.
- High-Efficiency Furnaces: These energy-efficient models can cost more upfront but can save you money on your heating bills over time. They usually start around $5,000 and can go up to $10,000 depending on features and installation needs.
The cost also includes installation, which can range between $500 and $2,000 depending on your location and the furnace type.
How Often Should You Replace Your Furnace Filter?
In addition to replacing the furnace, keeping your system running efficiently requires regular maintenance. One of the simplest ways to keep your furnace in top shape is to replace the filter. So, how often should you replace your furnace filter?
- Every 1–3 Months: Generally, it’s recommended to replace the filter every 1–3 months, especially during the heating season when your furnace is running frequently. If you have pets or allergies, you might need to replace the filter more often.
- Check the Filter Regularly: It’s a good idea to visually inspect the filter monthly to see if it appears clogged. A dirty filter reduces airflow, making your furnace work harder and less efficiently.
Regularly changing your furnace filter helps extend your furnace’s life and ensures clean air quality in your home.
Signs That It’s Time to Replace Your Furnace
Knowing when to replace your furnace is crucial. Here are some signs that indicate it may be time for a new one:
- Frequent Repairs: If you find yourself calling the repair technician often, it may be more cost-effective to replace the furnace instead of continuing to pay for repairs.
- Uneven Heating: Cold spots in your home or uneven heating could indicate that your furnace is struggling to perform its job.
- Rising Energy Bills: If your heating costs have been climbing despite normal usage, it may indicate your furnace is no longer running efficiently and needs replacement.
- Age of the Furnace: Most furnaces last 15-20 years. If yours is reaching the end of its lifespan and you’re experiencing issues, it might be time for a replacement.
