Home Heating Assessment

Should you repair or replace?

If your furnace is only a few years old, a good repair job should fix any problem.

But the average lifespan of a furnace is about 10 - 15 years. If your furnace is around this age,it might be time to look into replacement instead of repair. Today’s furnace are designed to save you money and keep your family comfortable.

If you’re consistently having issues with your furnace or keeping your home warm, call us at 618-477-8337 for a free home heating assessment.


Our Home Heating Assessment gives you insight into why your home never feels comfortable and what can be done to fix the problems. This assessment looks at your current energy usage, equipment, and insulation levels to help our team design specific energy savings solutions for your home.

When it comes to keeping your home comfortable and safe, your furnace is part of a bigger system. We can repair or replace your old heater with a high efficiency furnace, which will result in lower energy bills. However, there many other ways to make your home even more comfortable and energy efficient.

For example, if you feel drafts throughout your home, that means your home is losing air and valuable heat. Repairing or replacing your furnace is only part of the solution. Places like your attic, chimney chases, even lighting recesses let warm air escape.

The best performing furnace is only as efficient as the home it is inside.

  • Cold floors

  • Drafty or cold spots throughout the home

  • High energy bills

  • Inconsistent heating

  • Poor ventilation

  • Dry air
