Hi, thanks for the video. It's very interesting and important to see what happens in a worst case scenario. It lets us homeowners know how critical it is to have everything working properly as it was designed by the manufacturer.

hi, thank you for sharing experiences as usual.

Really helpful class Mr. Branaman, Thank you

Great video!

Thanks 🌹

Very informative

You are better than "HVAC SCHOOL" Thanks Brother

Well I'm not better than anybody. I just bring a perspective that some can identify with better. I love HVAC. I just glad I can help some people.

@@love2hvac I will have to agree. I love Ty and Bryan. Everyone explains things differently and every person understands things differently. It's like saying one thing smells better then the other. Well that's to you but not to everyone. I have watched Ty's videos multiple times and have encouraged others to do the same. (I actually have a telegram channel with over 100 HVAC subscribers and I link all your videos, people love it). Keep up the great work.

thanks man

Great as always. Question regarding the thermal imaging camera you got on your phone. How happy are you with it? And can you post a link? I have been looking for something good. Thank you

It's the FLIR1 It works great for checking receiver levels, evaporator, duct leaks and basic infiltration, and insulation issues. Its not powerful enough for thermography or energy auditing but its just right for me.

how do you adjust newer limit switches?

I still have a fan limit switch in my garage and works fine and reliable and cheap to replace. What is the benefit of the new time delay Boards that replaced the fan limit switch. I find that all the service on the new units are because expensive new style parts have failed vacuum switches and time delay boards which never match and cause units to be left down leaving customers with no heat for a few days. So I don’t see the benefit of new control boards. Thanks Eric

I completely understand where your coming from. Simple is less moving parts, less breaking, easier repairs. However that does not stop change. I remember working on cars with carburetors and simple electronics that could be repaired in the fly. The push for more energy efficiency and safety drives both of these changes. My issue is not with the fan limit control, it's with the natural draft furnaces that notoriously had back draft and cracked heat exchangers. That was an issue back when they where new. Now considering they have not made a natural draft furnace (exculding shop heaters) since about 1993 all the ones out there are a high risk. I remember replacing the old style fan limit switches every week back in good ole days. I had one of each size. When they rusted up they would overheat the heat exhanger and cause cracks often. Universal pressure switches can be stocked on the truck now days. I even keep universal control boards to get them running until the replacement comes in. In some cases I have brought my customer temporary heaters rather than risk a CO safety.

I have 2 lifesmart 1500 heaters that I loan to customers while installing their new boilers but I don’t see the benefit of progress when I have to supply temp heat to do service on these units. And customers don’t like to pay for the heaters that’s why they had furnaces or boilers. I guess that’s why we are a dying breed of mechanics. I enjoy your videos and your way of teaching. Thanks eric

I have a question: Will a crack in the heat exchanger cause CO levels to rise drastically in the exhaust flue? If so, can you please explain why that happens. I understand how a cracked heat exchanger will cause CO to go into the home but I don't see how CO levels will increase in the exhaust flue. Thank you in advance.

In short, the excess air causes the flame to cool too rapidly, and it changes the flame pattern causing flame impingement against the heat exchanger. A cracked heat exchanger can cause high flue CO. High flue CO does not mean it's a cracked heat exchanger. I like to look at CO and 02 before and after the blower runs. If the blower kicks in and then CO and 02 both go up, its then I'm looking at the heat exhanger.

it will, but will not make it too bad as I can understand. The reason is very simple: when there is a crack in heat exchanger, the inducer motor will draw air from both outside and inside of the heat exhanger, that means it wont draw strong enough air from inside of the heat exchanger, that means no enough air flow going through the in shot (combustion)part of the furnace, that means problems, obviously none fully combustion.
