A Reddit user got a huge helping of advice from the site when they asked about the state of their furnace.
Posting on the r/hvacadvice subreddit, they explained their situation.
"A local HVAC company came out to my house to look at the furnace as we are trying to sell the house," they said. "They claim the furnace is from the 80s, only has a 15 year lifespan, and is currently a hazard. They have red tagged it and are saying it is unsafe to live in the house while the furnace is installed."
The poster shared pictures that showed a clearly rusted-out heat exchanger on their furnace.
The heat exchanger is the most important part of any furnace. It pushes the air through and heats it up, typically via natural gas flame in a furnace of that age. When they are as damaged as that one is, it can leak carbon monoxide into the home, which can cause illness and death.
If you, like this person, are in the market for a new furnace, consider upgrading to a heat pump. They use drastically less energy than a traditional furnace, and without the natural gas being used, they are much safer and healthier for you and your family.
Resources like EnergySage's Heat Pump Marketplace can help homeowners find more information about the installation and cost savings available for heat pump installations in their local area.
Commenters on the post were quick to point out just how dangerous using this furnace would be.
