Welcome to HVAC No Bull Forum. Real jobs. Useful answers. No bull.

We’re giving the HVAC School community a better place to talk shop. Think of the useful parts of an old trade forum: a question you can find again, photos that help explain the job, people who will tell you what they know—and what they don’t. This is for working HVACR and building performance people. Technicians, contractors, consultants, specialists, and instructors. Residential, commercial, refrigeration, controls, airflow, moisture, and the building around the equipment. Start with what you’re seeing. Share a photo. Ask for a second set of eyes. Bring back something you learned at the symposium. When you find the answer, close the loop so the next person can learn from it. Disagree with the diagnosis. Explain your reasoning. Treat the person with respect. No pile-ons, customer ridicule, or hidden sales pitches. Your existing HVAC School account works here. Earlier posts remain in the searchable community archive. Pick a room, introduce the work you do, or bring a question from your day. For techs. By techs.
