Once again a great video.

[@ryancolbert1701]

All these updated furnace videos are great, i learned half my service skills with furnaces from the old videos you had but these new ones are a level above, great job as always craig! Love what you do for our industry

[@acservicetechchannel]

Glad you like them, thank you for watching!

[@deanmartin1966]

Great refresher

[@macthemec]

Great video showing a propane conversion, also glad its a carrier as carrier/ICP is my go to for re&re’s

[@SalahDambo-gb6cs]

Time is golden, use it for what excites you

[@chesstime356]

As always I like your videos I can’t stop watching your videos thanks.

Great Video. Thank you for sharing. Have a nice weekend

[@acservicetechchannel]

Thank you! You too!

Extraordinario

[@thesonubal]

Hi Craig What size fittings did you use for manometer tubes?

[@spartan5106]

Great video!

[@sunriseeternity300]

What is the transition fitting on the monometer tube, made from? Good idea.

[@jixia676]

Hi, Craig. Is there a way to diagnose the modulating gas valve? There are videos about single and 2stage gas valve. But I can't find any modulating gas valve troubleshooting. Thanks

[@timothynovitski9133]

What did you use for your transition pieces?

[@danielkelley7422]

Hi Craig. Great video. Do you have any videos on combustion analysis? As far as what you should be looking for with the different readings.

[@acservicetechchannel]

Check out our video featuring Tyler Nelson! kzbin.info/www/bejne/aXzMfoeKlNZ6n7c

[@danielkelley7422]

Thanks

[@InsideOutElectronics]

Good video ! Thank you What if 24V to the gas valve is applied only for 1 or so second, Obviously no gas coming out and igniter is off in another 1-2 seconds. Wondering what does it mean ?

[@orhanismet37]

great channel, is it possible to play subtitles in bulgarian language. thanks

[@mikev.1034]

👍👍

[@user-yl1ug3gg2w]

can galvanized pipes be used with LP?

[@adamm4064]

Hi Craig. I'm probably going to buy your book on Air Conditioning. Do you have any recommendations for a furnace book?

[@acservicetechchannel]

You could go with ESCO's book on gas furnaces. I would love to make a gas furnace book in the future, thanks!

[@user-np5yw3ox1g]

Hi Craig, I'm a construction trades teacher in Northern Michigan. I'm looking for recommendations to teach my students the basic principles of residential HVAC. We build spec. houses with my students over two years. I try to teach every aspect of residential building and I'm looking to cover the basics with the limited time I have. My students work with the local HVAC company to install the furnace/ac, and ductwork for the spec house. I'm looking for classroom activities that I can use to reinforce the onsite installs. Any recommendations would be appreciated.

[@acservicetechchannel]

Thank you for sharing your story! We offer some free HVAC educational projects/classroom activities here, www.acservicetech.com/hvac-classroom-training-projects

[@YTsux24-7]

I've seen my manometer fluctuate considerably with the brass cap on verses off while adjusting gas pressure. I'm not sure why this occurs.

[@remodelman8371]

Galvanized pipe for gas line?

[@airconditioningheating]

Today I had a service problem. Checked gas pressure at the gas valve ,inlet was 7.5 w.c and when the rooftop fire up inlet pressure drops to 4.7/5.1 ( is this normal.?? ) and the outlet pressure is like 1.7 ,unit runs x 1 min and shut down. Gas valve is new .Gas company was a couple months back and replaced gas meter for bldg , before that unit was working fine.

[@BRADASSOFFGRIDHOMESTEAD]

Why are people still using PVC primer? FUSION PVC glue is readily available and works flawlessly.

[@YTsux24-7]

Local jurisdictions and manufacturers' specific instructions usually dictate how PVC venting can be installed. One step glue/primer is often not allowed.

[@BRADASSOFFGRIDHOMESTEAD]

@@YTsux24-7 Figures, they are never up with the current times.

[@NorCal-refrigeration]

@@YTsux24-7yep I used clear primer and to rip it all out. Inspector wanted to see purple. Fawk ed me good.

[@macthemec]

IPEX 636 literature says you have to use primer, local code says to follow whatever guideline has a higher threshold (eg if local code says zero clearance and manufacturer says 1” you follow manufacturer) For the other guy talking about primer i use clear in re&re and purple in new construction, but when i use clear i use enough to wipe out some of the lettering and have the lettering visible so i can show the gas inspector if necessary, however i have a good reputation with the local gas authority and they don’t usually inspect my work

[@stevenfalzon3340]

Because the code says so
