Condensate Drainage in a High Efficiency Gas Furnace
This article was written by HVAC/furnace technician Benoît Mongeau. Thank you, Ben. High efficiency (or 90%, or condensing) furnaces use a set of two heat exchangers to retrieve more heat from the combustion products than their mid-efficiency counterparts. Because of this, they generate flue gases much colder than those of a mid-efficiency or […]Read more
Does a Furnace Decrease Humidity?
Does heating the air cause the humidity in the air to decrease? Yes and no. Heating air causes the RELATIVE humidity percentage to decrease, but it does not change the overall moisture content in grains of moisture per lb of air. Many old-timers will swear a blue blaze that oversizing a furnace will directly result […]Read more
Checking Evaporators on Furnaces
In Florida, there are not many gas furnaces—at least not as many as up north. Sometimes, we can look like real dummies compared to techs who work on them every day. One thing to know about 80% gas furnaces with cased evaporator coils is that you can often check the evaporator coil by removing the […]Read more
Good quiz although was mainly review for me (Arrghrr two I missed I knew better!)
As your time & interest permits, I could use gas furnace and air-source HP troubleshooting type quiz questions to aid in my experience development.
As you probably aware, grayfurnaceman.com seems to be big on YTubes on gas furnace problems then others I’ve seen.
Please know that, besides HVAC School being recently added main source of my learning & review, I regularly view acservicetech.com YTubes.
I appreciate both yours and his teaching and knowledge imparting styles since are crisp, concise, and clear – also respectful and safety and do-it-the-right-way oriented.
However, I like really appreciate HVAC School for the not using YTube videos since the web site resources, quizzes, emailed & posted articles with diagrams allow one to print & keep in my 3-ring reference binder. Also the listening podcasts use little cell phone data bytes. I don’t always have time to view videos or see my cell phone data GB limit exceeded. Enjoy when you and Nathan cutting up although sometimes a little zany and hard for me to keep up, comic relief is appreciated.
Thanks for your time and dedication to improving the industry. Your perspectives, ways of approach, and knowledge make professional techs proud to be in the HVAC-R industry.
P.S. I realize web site title is HVAC not HVAC-R but, if I may add to my wish list, would also be interested in commercial refrigeration troubleshooting. I had a class Spring 2016 semester on Comml Refrig but limited in school lab what can practice.
This is awesome thank you so much and ready for more to keep in tip top Tech for the ones who we depend on our Clients.
HAPPY NEW YEAR
Same to you fine sir
Great quiz, normally don’t work on them till they go out on flame failure. The brand I get to touch are Aerco boilers
That’s a very interesting high efficiency furnace quiz. Most guys with no schooling couldn’t pass that quiz.
Can these test and podcast be shared on my facebook buis page? Good content. Keeps the pencil sharp
Yes, you may share our content anywhere you like
Much better this time, had to redeem myself after that refrigeration quiz! Good stuff keep it coming.
Consider yourself redeemed
I agree I bombed the refrigeration quiz
I am fairly new to HVAC, This site is really nice and now i have informative info to listen to as I drive between campus’ that i maintain the HVAC systems for. The more I learn the more I see I have to learn. Thanks for sharing and helping us new techs. It has been very helpful to me as I strive to become the best tech i can be.
Well I got a 1000 ego points, just call me super tech haha.
Fun quiz. At this point I would be very up set with anything less than 10 on gas heating.
I enjoyed taking this quiz! Helped out but I was also wondering if these get updated because apparently question 4 all answers were wrong and on the evacuation quiz one of the questions didn’t have an image
