I never respond but I cringe as neighbors post about issues with furnaces or plumbing or an electrical problem and manage to solicit advice from random people they have never even met. The people who respond never state their qualifications. All we really know about them is that they are on social media most of the time and always ready to comment.
Chances are your neighbors are not HVAC experts, plumbers, or electricians. They may have had one experience once and want to share their knowledge.
People who do not want to ask an expert or do not want to hire a licensed professional would be much better off consulting YouTube or in the case of a furnace the owner’s manual.
Hiring a qualified licensed, reputable professional is often the best and even the least expensive option.
