    Wow, wow, wow, your videos that you are showing online are phenomenal. I was an aircraft mechanic for 20 years then I became a locomotive engineer for the last 16 years, now I’m retired. When it was time to replace a 30 year old furnace I thought why not just get a package AC/furnace unit. After installation, (installed by licensed personal) I opened the panels to get model numbers and serial numbers for warranties. I thought to myself what a mangled spaghetti mess of wiring, all of this just to run a furnace and air conditioner. After realizing the cost of any service call, I decided that I needed to learn how my furnace works.
    After two months of watching all your videos I’m able to identify what every wire does in my furnace and AC compressor unit. I know what each component does and the purpose of it. I'm still learning some troubleshooting techniques. At this point the only thing that I know that I will not even attempt to do is to, replace any component that will break the integrity of the refrigerant system. If anything needs to be braised/soldered, the cost of having that done will be close to the price of a new unit. Its better just to buy a new unit. I did take an AC course in collage for diesel mechanic in which we had to get a 608 certification. I don't know if you offer that or not, but this would be the place to learn on how to handle refrigerants
    Every homeowner needs to know how this equipment works, even if they're not going work on it, they still need to know how to maintain it. I can only imagine how many house fires were caused by homeowners neglecting and or being naive towards their furnace and AC units.

      Watch "HVAC School" videos on refrigeration cycle and EPA 608. Fundamentals first. Expansion equals loss of heat and compression equals heat. One coil and fan distributes heat, another coil and fan distributes (loss of heat) cold. Fan speed/size, duct sizing, lineset sizing and coil sizing determines rejection of heat or (loss of heat) cold.

    Thank you - Great video in explaining everything about the furnace! But I do not understand the explanation of the ground voltage drop test @52:35. Why is the check measurements are in ohms instead of volts? I think you may meant to say is that with the power on (120V), the voltage drop should zero (therefore no resistance ), but if instead the voltage reading is like 0.4 V then that means there is problem (i.e. there is unaccounted resistance somewhere)?

    I have a high efficiency furnace, according to the tech that came to look at it, but they think we need a new one and its a 2008 model lennox furnace. when do you think one would upgrade a furnace given the age of my furnace. Of course, like a car, one has to maintain it but im a new home owner and learning more each day about our home, including the furnace.

    Hi, My gas furnace starts up like normal and after the main blower turns on and starts heating the house I notice the burner turns off for about 15 seconds then lights back up and continue turning on and off until the house is up to temp and then shuts off? I never noticed this before, is this a normal thing or is there something wrong and if there's something wrong what would it be? thanks, Dave

    I have one of those high efficiency goodman and it's like new yet but in the spring we ran out of propane so I didn't refill it till the other day and now it won't fire up as the igniter fires up but I don't hear no gas or see no fire, could the line have air in it that needs to be bleed out since it sat empty all summer ? when I get home today I'm going to pull the plug going to gas valve and see if I get 24v so of someone knows maybe what wrong with it let me know. also the red light is blinking code 1

    i have a 60% , it will spark and lite the pilot but will never open the main burner valve. I put and extra ground wire to the Flame Sensor and ECM, cleaned the flame sensor and still does the same. I have i think 3 terminals on the main gas valve, is there a way to put 24 volts to this valve to test it? ( I also tried to measure AC voltage to the flame sensor but had no luck. ) Thank you

      Check for 24 volts at main gas valve,if you have 24 the gas valve could be bad and sticking,if you got the 24 volt at valve you could lightly tap on gas valve and see if it opens,if you dont have 24 volts at valve,the control board could be bad

    Is there ANY way that a 90% natural gas furnace could be venting what smells like a faint smell of "car exhaust" or the like!? I feel like when my furnace is on blowing I can detect that. It is not all the time either. It only seems to happen when the temperature goes down to colder temps. Is it possible to have a crack or something like that in the heat exchanger or something that could cause this? Also, I feel that in the summer I can also detect something when the cooling unit is on blowing. I dont know what to think about all of it! ?

    Is it correct that my 25 year old Carrier 58GSC series upflow furnace does not have an inducer motor? My problem is that I set my thermostat and flip on the furnace power switch but only hear a click or clunk sound but nothing else happens.

      Being that old,it might or might not,but it still will have a sequence of operation,what type of ignition?Do you own a meter have you checked voltage,power to furnace,24volts from transformer?If you dont know if you hsve an inducer or not you might want to call a professional.

    Could you do a TH-cam video on a Crown Bimini Gas Boiler? Mine is a BWC225 with Honeywell MCBA14201D controller board, Honeywell Gas Valve VK8115V 1036 4, Honeywell Venturi? Valve VK8115F 1134 4, and Whatever the Factory Supplied Combustion Fan is (I don't have that info). Right now the burner flame is mostly ORANGE. So if I can't get it fixed,, it will be replaced and donated to you. Thanks, Chuck

    Since purchasing it, th-cam.com/users/postUgkxQuBMI30VhO6fDed6NOsYftsoNa8x0UZ5 this fan is a trustworthy companion during the hot nights in Texas for me. The sleep mode is really quiet and gives you smooth wind to cool down. At full speed the fan is quite noisy but also very strong.Only weird thing is that if there is a draught from another fan, the sleep mode would speed up occasionally (getting a bit louder, probably to level 2 out of 4). This never happened so far when I used only this fan though.
