One Pennsylvania homeowner's question about a brand-new furnace installation offers a simple safety check for anyone looking at HVAC work.
If a flexible gas line goes straight into the furnace cabinet, it may be worth getting a second opinion.
Here's what to know
In a post to Reddit's r/HVACAdvice community, a Pennsylvania resident shared an image of a new installation after getting two different assessments.
The original poster noted their installer said the work was up to code, while another company said it was not, with the dispute focused on a flexible gas connector entering the furnace cabinet.
The thread response was largely critical of that setup. One commenter wrote, "Can't have flex gas line entering the cabinet. Needs hard pipe coming out of furnace the flex would then connect to. Vibrations could potentially cause the flex to rub against the metal and create a gas leak." Several others offered similar advice.
Another commenter added, "I'm also concerned why your AC drain line is disconnected."
More background
A problem with gas piping isn't just a code dispute; it can quickly become a safety issue, a comfort issue, and a financial issue if a faulty installation leads to repeated service calls, breakdowns, or higher energy use.
Still, upgrading your heating and cooling system is one of the most direct ways to reduce household energy waste, cut monthly bills, and avoid getting stuck with a system that becomes more expensive to operate over time.

Questions about a new furnace or AC install rarely end with one odd-looking detail. These stories show how safety concerns, conflicting technician advice, and expensive repair decisions can leave homeowners trying to figure out what's actually wrong.
• In Pennsylvania, an HVAC company told homeowners that furnaces could 'blow up' to pressure unnecessary replacements.
• A homeowner smelling gas near a new furnace learned 180 ppm is too high.
• After basic AC service, one homeowner felt gaslit and lied to by a $20,000 quote.
