I understand this is a residential based instructional video, but most RTU's are commercial based with an economizer installed. You should release a video on economizer troubleshooting and operation as well. I appreciate your videos and instructional content. They are very well thought out and presented. I myself am a commercial/ industrial service technician, who enjoys watching and learning. You don't see many RTU's in a residential setting. Do you ever cover the more typical commercial equipment? Thanks for what you do for the trade. Helping younger techs become better more proficient individuals
no matter how many times or how old your videos area, as an experienced hvac/r tech, I always learn something from you. Thanks for those words of HVAC wisdom!
My name is Andrew. I just met you today and saw your presentation at the symposium. I wish you had more time to present but I got a lot of good information from it. Your presentation was the most relative to what I actually do on a daily basis. Thank you for being a dedicated HVAC teacher.
Andrew, thank you so much for writing this note! i wish i had made the presentation a little tighter or had more time but i will probably make a full length video later of it. Make sure you come over and say hi in person. I will be at the symposium again today, thanks brother!
As always an excellent video. I’m a retired master plumber/ gas tech . By the way I bought your book. I used it along with your videos to replace my ac system. Everything went smoothly thanks to you.
A very helpful video. Fantastic. Some of the issues, like the weld seems on the heat exchanger or some of the rusting, could be avoided if the manufacturers changed their design just a bit.
You mean expansion compression tank? The older styles, sometimes you have to isolate and drain them. Over time they will completely fill with water and have to drain them once in awhile.
On that unit those circuit board crack on the main saftey switch plug always check the back of those boards on that 9pin connector. Very common problem.
My problem is that the furnace works, for only like 20 mins or so. It will shoot up to the temp I program on the wall thermostat (say 73F), reach that temp, shut off, and NOT come back on later so the apartment gets super cold, and never come back on. Now there is one trick -- at bottom of furnace is a large red button, I push that red button all the way in, and SOMEtimes the furnace will turn back on for another 20 mins, but sometimes not. On rare occasions the furnace will function for 3 or even 4 hours, but not often, and wouldn't you know it, it usually shuts off when I get in bed. Note: I already cleaned the furnace flame sensor one time with the brillo end of a dish pad, so that's probably ruled out. (Furnace brand is Williams, model 2509622).
You may have a faulty sensor that is designed to open when a "condition" happens or not happening. The flame sensor is no exception. I haven't looked at your schematic, but consider looking at what other components are wired in series with your flame sensor. Edit: you may not wanna keep pressing that red button.
The inducer motor runs even when the thermostat shuts off and the system itself isn't igniting. I had to cut the breaker off to stop it from running constantly! My unit is 3 years old and I really don't know what to do!
What if the exact same unit heat goes on and off ? I checked the burner , ignition switch works but burner doesn’t go on ( no flame ) ? Some days it works but some days it doesn’t:(
Red light on board goes out when unit calls for heat. Comes on, Inducer motor tries to start, shuts right off. Keeps trying. Red light goes on and off during this. Any ideas? Bad transformer?
A guy I use to work with called me about his furnace it would go through the sequence of operation fine but after glow plug no ignition . He said the glow plug has a white spot on the glower I told him he needed a new one. He tried to jump it out called me back said it sparked on him and he had to reset the breaker, now his inducer comes on for a short time like a minute then stops and the fan come on. Any idea what he may have messed up, I'm thinking the pressure switch is acting up
Easy way to test pressure switch is putting meter leads on both terminals of the switch. And taking the tubing to your mouth and pulling in like you would a straw. It’ll close the contacts and if it’s malfunctioning it won’t close contacts.
And? Lol. As an automotive technician and now being an HVAC tech sometimes I wear gloves sometimes I don't. You're not going to wear them in every instance. Actually you really don't have to. Only time I really wear gloves is if I'm dealing with sheet metal or it's cold outside.

I had never seen an outside unit like that. Here in AZ they're all inside. I learned to fix mine thanks to TH-camrs such as yourself. Thank you sir!
I've been an installer for about 35 years, NOT SERVICE. You are my go to guy.

@@acservicetechchannel no worries. I still got a lot out of the presentation and look forward to a video with the rest of the information.
Can't stop watching your videos

I fixed mine today,thanks a lot
Great tech information
Thanks it that time in N Ga thought 80 today.
Awesome vid once again Craig
I had a rooftop package unit with a cracked heat exchanger on Saturday that would not light due to the cracks.
Thanks so much....vere clear explained
Awsome videos , such channels motivate us in our new channel , we like this channel so informative and professional keeps it up
A very helpful video. Fantastic. Some of the issues, like the weld seems on the heat exchanger or some of the rusting, could be avoided if the manufacturers changed their design just a bit.

Awesome 👏 lot of help
Thanks for your informed video
Thanks
thanks tech, another good one for my knowledge thanks a lot!
Always great video thanks you
I'll watch later today. Did you mention not having a way to vent an old expansion tank? Pressure keeps relief valve off the furnace leaking.
You mean expansion compression tank? The older styles, sometimes you have to isolate and drain them. Over time they will completely fill with water and have to drain them once in awhile.
Always good stuff, keep em coming. Could you do some trouble shooting on ecm motors/control board diagnostics
He has one. Just search ecm motors troubleshooting. Should be the first or second video.
Sir, during a power outage, can I make heater on this unit working by using generator, just like on split system?
Love 🖤🖤 From Bangladesh
As always thanks for the vids.. 👏🏾
Thanks for the info sir 👍
great video
best info
On that unit those circuit board crack on the main saftey switch plug always check the back of those boards on that 9pin connector. Very common problem.
Thanks for the info, much appreciated!!! I have your A/C charging and service procedures book, have you ever thought about a heating book?
so you killed power ? but tested everything live ? or inducer fan and electrical still have voltage when disconnect is pulled ?
Great videos.Best on TH-cam 😜GREAT BOOK also
Good info
Thanks for the videos!
🍺🍺🍺🥃🥃🎯🏌🏻♀️
Stay safe.
Retired (werk'n)keyboard super tech. Wear your safety glasses!
Great .
HELP!!
My rheem package furnace only works in warmer weather. I cleaned the flame sensor. What do you think the problem could potentially be??
My problem is that the furnace works, for only like 20 mins or so. It will shoot up to the temp I program on the wall thermostat (say 73F), reach that temp, shut off, and NOT come back on later so the apartment gets super cold, and never come back on.

Our gas valve seems to freeze. Very little gas output in the cold such that the burners do not ignite and they system cycles off
Can somebody please recommend a good heating troubleshooting field guide?
The inducer motor runs even when the thermostat shuts off and the system itself isn't igniting. I had to cut the breaker off to stop it from running constantly! My unit is 3 years old and I really don't know what to do!
You are the best
good
What if the exact same unit heat goes on and off ? I checked the burner , ignition switch works but burner doesn’t go on ( no flame ) ? Some days it works but some days it doesn’t:(
What is the multi meter set to?
Red light on board goes out when unit calls for heat. Comes on, Inducer motor tries to start, shuts right off. Keeps trying. Red light goes on and off during this. Any ideas? Bad transformer?
A guy I use to work with called me about his furnace it would go through the sequence of operation fine but after glow plug no ignition .

Any idea what he may have messed up, I'm thinking the pressure switch is acting up
Easy way to test pressure switch is putting meter leads on both terminals of the switch. And taking the tubing to your mouth and pulling in like you would a straw. It’ll close the contacts and if it’s malfunctioning it won’t close contacts.

Wearing safety glasses but no gloves.
Like a man. We like to feel things, with our fingers bub. Leave the pretty soft hands for the girls.
Sissy hands
And? Lol. As an automotive technician and now being an HVAC tech sometimes I wear gloves sometimes I don't. You're not going to wear them in every instance. Actually you really don't have to. Only time I really wear gloves is if I'm dealing with sheet metal or it's cold outside.
