October 14, 2025

One Minnesotan couple experienced the real-life dangers of skipping a furnace safety inspection when they started their furnace for the first time and had to be airlifted to a nearby hospital. 

Why Every Minnesotan Homeowner Needs To Test Their System

After months of sitting idle, your heating system is especially vulnerable to numerous hidden risks and dangers. More than 400 Americans die from accidental carbon monoxide poisoning every year, according to the Center for Disease Control and Prevention. Known as the silent killer, carbon monoxide poisoning symptoms often present themselves while masking as other causes.

What Are Symptoms of Carbon Monoxide Poisoning?

When carbon monoxide builds up in your blood it replaces the oxygen in your red blood cells leading to serious tissue damage and even death. 

How Do You Know If You're Suffering From Carbon Monoxide Poisoning?

If you think you may be suffering from carbon monoxide poisoning, leave your home and find fresh air immediately then seek medical attention by calling 911. 

Test Your Home Today!

To know if you or your home have carbon monoxide, there are three steps you can take to reduce your risk of poisoning.

  1. Install Carbon Monoxide Detectors

    Place detectors on every level of your home, especially near sleeping areas, and check them monthly. Carbon monoxide evenly mixes with the oxygen in the air, so install your detectors away from “dead air” corners, 3-5 feet from the floor or close to the breathing height of your family. Carbon monoxide detectors should be replaced every 5-7 years and avoid installing them near appliances or close to windows or doors. 

  2. Test and Maintain Your HVAC System

    Have your licensed HVAC technician out to inspect and test your entire HVAC system to ensure safety, optimal output and increase your efficiency. At Bob Boldt HVAC, our team conducts an in-depth safety inspection and diagnostics on your entire heating and cooling system.

  3. Check for Visible Signs of a Carbon Monoxide Leak

    To see if your furnace has carbon monoxide leaks check for visible signs such as: soot stains on or nearby your furnace, a yellow pilot light, excessive condensation on your unit, a stale or stuffy smell, rust on your units vent pipe, your pilot light blowing out constantly or unusual noises.

  • Headaches
  • Weakness
  • Dizziness
  • Nausea or Vomiting

  • Confusion
  • Blurred Vision

How Does Carbon Monoxide Get Into My Home?

This silent killer can build up in your home due to improper ventilation or incomplete combustion from your fuel-burning systems like furnaces, water heaters or stoves.
