As a homeowner in Sioux Falls, you're likely no stranger to the importance of a reliable furnace. But what happens when your trusty furnace starts to show its age? Is fixing a 10-year-old furnace worth it, or is it time to consider a new installation? At True Temp Homes, we've seen our fair share of furnace repairs and replacements, and we're here to give you the honest answer.

Understanding Furnace Lifespan

A typical furnace can last anywhere from 15 to 20 years, depending on factors such as usage, maintenance, and quality of the unit. However, as your furnace approaches the 10-year mark, it's not uncommon to start experiencing issues. Preventive heating maintenance can help extend the life of your furnace, but it's not always enough to prevent problems from arising.

Common Issues with Older Furnaces

Some common issues with older furnaces include:

  • Reduced efficiency, leading to higher energy bills
  • Increased risk of breakdowns and repairs
  • Potential safety hazards, such as carbon monoxide leaks
If you're experiencing any of these issues, it may be time to consider new furnace installation. Our team at True Temp Homes can help you determine the best course of action for your specific situation.

When to Repair vs. Replace

So, how do you know when to repair your furnace versus replacing it? Here are a few factors to consider:

  • Cost of repairs: If the cost of repairs exceeds 50% of the cost of a new furnace, it's likely more cost-effective to replace
  • Age of the furnace: If your furnace is approaching or has exceeded its expected lifespan, it may be time to consider replacement
  • Energy efficiency: If your furnace is no longer energy-efficient, it may be worth considering a new, more efficient model
Our team at True Temp Homes can help you weigh these factors and make an informed decision. We also offer thermostat installation and airflow balancing services to help optimize your furnace's performance.
