How do I troubleshoot my HVAC system? How do I troubleshoot it? Let me give you the fast answer. How you can troubleshoot it is don't. Don't do it. There is voltage, there's electricity, there's refrigerant, there's all these things playing into your HVAC that could be a problem. So instead of trying to figure it out and you trying to troubleshoot what the problem is, call a professional. Get a pro out to your home to see what's going on with your system. I know we're in a— we're in the stage of YouTubers and do-it-yourselfers, and let me YouTube the answer, let me see what's going on with this. I know it's very tempting to do that. But you're talking about the biggest appliance in your home, one of the biggest. Your HVAC system consumes a lot of power. It's one of the biggest appliances you have. It's very technical. It's not like a refrigerator where you plug it in, it works, or it doesn't work. It's not like that. There's a lot involved in your HVAC system. So if you're trying to troubleshoot it outside of a blank thermostat, you need batteries. Stay out of the electrical panel, stay out of the panel in the outdoor unit, stay out of the panel in the indoor unit. Leave it to a pro to come by, diagnose it, properly diagnose it, give you a warranty on what needs to be done That, that's a— that's one of the big pitfalls I see too, is that a lot of do-it-yourselfers or YouTubers— hey, I got this thing online, I need help installing it. Hey, I got this from a distributor, I got my own compressor, can you put it in for me? Dude, leave it to the pros. It's going to cost you a little bit more money to have a parts and labor warranty, but you have the backing of a professional company to help you out. So by all means, lean on that, lean into that, and don't try to open anything and mess with your system.
