Question 1

How often should carbon monoxide detectors be tested?

Accepted Answer

Test the battery monthly and replace the unit itself every 5 to 7 years, or sooner if the manufacturer recommends it.

Question 2

Can a furnace be unsafe but still heat the house normally?

Accepted Answer

Yes. A cracked heat exchanger or a carbon monoxide leak can exist alongside completely normal heating performance, which is why a visual or comfort check isn't enough on its own.

Question 3

What is a cracked heat exchanger?

Accepted Answer

It's a fracture in the metal component that separates the combustion gases from the air your furnace blows into your home. A crack allows those gases to mix, which is a safety risk regardless of how well the furnace still heats.

Question 4

Is an annual safety inspection required by law?

Accepted Answer

Colorado Springs doesn't require an annual inspection by law, but manufacturers often require one to keep a warranty valid, and it remains the most reliable way to catch a hidden issue before it becomes dangerous.

Question 5

What should I do if I smell gas near my furnace?

Accepted Answer

Leave the house immediately, don't use light switches or phones inside, and call your gas utility or a technician from outside once you're safe.
