If you are experiencing issues with your HVAC system PLEASE call a professional.

This subreddit's spam filter requires an account older than 24 hours and positive combined karma in order to participate. We will not manually approve posts that don't fit this criteria.

This is not a question and answer subreddit. Full stop. Any and all questions from outside the trade go in r/hvacadvice.

This is a subreddit for hvac professionals to discuss tips, tricks and information - including humor, memes and our favorite jobsite supervisors.
