Did you ever figure out the wiring for this? Is there a way to control speed using the those 5 terminals?

thank you for helping me with this rough letter. I already did mine.

Hi guys,

Does anyone has a sample letter for challenging 308R residential sheet metal? I just want to see the idea of it.

thank you

Without knowing where George Brown gets its "practice test" from, it's not possible to answer that. Too much studying is never a bad thing. At the end of the day you need to know, and be comfortable with, the codebook.

Hello,
I have an exam next week, and I am preparing for it using a practice test I received from George Brown College. Is this sufficient, or should I practice more questions? If so, where can I find additional resources? Also, could you please let me know what questions you got on the exam?
Thank you!

Looking for opinions from the guys with residential experience.
Changed my furnace 2 or 3 years ago. No problems with the 1997 Lennox. Just old.Put in a Luxaire 2 stage with multi-speed ECM. No issues. Also installed a new 2.5 Ton cased coil with the intention of replacing condensing unit the following spring. Never happened. Hooked the existing 2 ton R22 Keeprite condensing unit back up. Not having any issues.
Thinking now about installing a MITSAIR add on heat pump and connecting to existing coil. MITS says their outdoor unit is compatible with any coil.
What do you guys think? I'm Thinking more about comfort, that I hope will come with inverter duty compressor, than energy savings.
Good idea? Bad idea? If good, do you recommend 2.5 ton to match coil or 2 ton? Kinda always thought existing AC was borderline at best.House is poorly built cookie cutter 1997 1800 sq ft.
I work in commercial/ industrial service. Figure some of you guys know this way better me.
Thanks for input and sorry for long post for short question.

Thank you, I will look into that

It could be a "chattering" relay on the furnace control board.  If you disconnect the G wire from the furnace does this still happen?

If so I would look at replacing the control board, and explain to the client that likely a dirty filter caused the furnace to cycle on limit and that eventually wore out the old relay due to all the excessive starting and stopping.
