Nice illustration

Thanks...I think ( you may be giving me $h!t about my artistic skills ) when I shoot these videos, I never script them out, I take two minutes to draw something and then I start recording, typically I do one take even if there's a flaw, for this 10 minute video, it takes me about 15minutes, I'm always by myself when I record, perfect was never my intension. I did see your unedited comment, and it's actually a good question, why would the "secondary" heat exchanger come before the primary one.... simple, if it was above the primary heat exchanger, the heat from the primary would re-heat the secondary. thanks for checking out my video, stay tuned more to come.

great video

[@abledistributors]

Thank You, I've got about one hundred ideas on new videos, hope you stay tuned, lots more to see.... Brian..

Your part 1 and 2 are great, thanks. You sound like Emeril, so entertaining too. I've watched several related vids and yours are succinct. Thanks and looking forward to more tech 'how to' info.

[@abledistributors]

Thank You, yes I have a lot more videos to do, some new products and a lot of Tech Tips, please stay tuned, more to come..

Great video as always. Thanks for sharing.

[@abledistributors]

thank you, stay posted lots more videos coming up.

Very informative.

💯 GREAT INFORMATION! The best thing you can do for your customers is install an oversized media filter. Im a HUGE fan of Aprilaire. Keeps equipment clean and VERY little static drop.

[@abledistributors]

Yes, after market "box" filters from GeneralAire, Honeywell and AprilAire are all good, but if you don't have the room for a 7" wide filter, a larger filter ( taller, put furnace on a 6" box ) will also make a huge difference. Thank You for checking out our video. Brian..

When I clean blower wheels and housing. I will use my coil cleaner. First a quick rinse with water then cleaner. Let set for 5 min. And rinse with high pressure from a garden hose if it is summer time and let dry. Vac out the return ell and blower cabinet. Once everything is put back together I check the balance of the blower wheel to make sure it does not wobble. Everything goes back nice and clean with a little lemon smell. The coiler cleaner makes the blower tin's nice and bright, and the home owner likes it.

Your Welcome, more videos on the way...

very good explanation.
From fan law2, we know that when the fan rotate faster ( high rpm ) the static pressure will be higher. So when take the test, which fan speeed should we choose to make the reference?

[@abledistributors]

I would have it on cooling speed ( if you have AC ? )... typically air flow is more of an issue during a cooling call, so I would test my static pressure on high. for heating I typically check my temp rise and if I have issues there I test further. I hope that answers your question.

Perfect. When cooling It is high speed. the static pressure will be the most.

7:50 Plz explain: “putting furnaces up on six inch return boxes, taking off the bottom of the furnace, and instead of a 16 by they are going with a 20 by filter rack.” Extending the cabinet to 20 inches? How? What is a 6 inch return box?

[@abledistributors]

you remove the bottom panel from the furnace, place the furnace on the open end the 6" tall box ( its the same dimensions as the furnace ) this allows you to install a lager ( taller 20" instead of 16" ) filter ( less restriction due to more filter area ) you cut some of the filter opening out of the side of the furnace, and the rest out of the 6" box, bigger filter and now the air can flow easier to the other side of blower wheel.
I guess its harder to explain than I thought, hope this helps.

@@abledistributors Where do you get the six inch box? From your local supply house? TY
