Understanding and Preventing CO Poisoning Risks with Portable Air Conditioners
Portable Air Conditioning Unit
Recently, we received a call from a concerned customer who had been experiencing persistent headaches. After a thorough discussion, we discovered that the issue was linked to her use of two portable air conditioners in her home. The headaches worsened whenever she used the dryer or took a shower, which led us to a critical revelation: she was experiencing symptoms of carbon monoxide (CO) poisoning.
The Connection Between Portable Air Conditioners and CO Poisoning
Here’s what was happening: running both portable air conditioners created a negative pressure environment inside her home. Essentially, these units were sucking air out of the house, which led to a dangerous situation when her atmospheric water heater was in use.
When the air pressure inside the home dropped significantly, the water heater's exhaust began to backdraft. This means that instead of the exhaust gases safely venting outside through the chimney, they were being drawn back into the home. This backdrafting of exhaust gases can lead to a dangerous build-up of carbon monoxide, a colorless and odorless gas that can cause severe health issues.

The Increasing Risk
This issue has become more common, especially during the summer months. We’ve encountered similar situations in about four or five homes this season. The root of the problem lies in the fact that when homeowners use portable air conditioners and close up all the windows to maintain a cool environment, the house becomes so sealed that it creates a vacuum effect. This vacuum effect pulls air in from any available source, including the chimney, which is not a safe way to ventilate the home.
How to Prevent CO Poisoning
Ensure Proper Ventilation: It’s essential to keep fresh air intakes clear and unobstructed. Regularly check that your home has adequate ventilation to prevent any negative pressure issues.
Install Carbon Monoxide Detectors: A CO detector is a must-have in every home. These devices can alert you to the presence of carbon monoxide before it reaches dangerous levels.
Consider Upgrading Your Water Heater: Replacing an atmospheric water heater with a power vent model can help resolve these issues. Power vent water heaters use a fan to expel exhaust gases, reducing the risk of backdrafting.
Explore Central Air Conditioning: If feasible, switching to a central air conditioning system can mitigate these problems by ensuring better overall air circulation and reducing the reliance on portable units.
