Stay warm and stay safe, Wichita! 🏠🔥
A furnace that "runs" isn't always a furnace that is safe. These photos show cracked heat exchangers we’ve discovered recently on several local units.
Why is this a big deal?
The heat exchanger’s job is to keep the toxic combustion gases (like Carbon Monoxide) separate from the clean air blowing through your vents. When the metal cracks like this, those dangerous fumes can leak directly into your home’s air supply.
The Scary Truth: * Cracks are often invisible without a professional inspection.
• Carbon Monoxide is odorless and colorless.
• Overheating and age are the leading causes of these failures.
Don't wait for your CO detector to go off or for your system to shut down in the middle of a freeze. Regular maintenance is the only way to catch these "silent killers" before they become a crisis.
Is your furnace ready for the season? Give us a call to schedule a safety inspection and tune-up. We’ll make sure your family stays cozy—and more importantly, safe.
