Too much cooling load on this HP?

I thought that was a special defrost mode?

Nah, there's a cottonwood growing nearby, it's time to clean the coil.

But wouldn't that clean the coil?

I actually had a customer call and say that smoke was coming out of the top of his HP in the dead of winter. I assured him that it was just steam from the defrost. He asked how does it defrost. I said by the hot gas. He said he did not have gas hooked up to his HP. I told him there is gas it his unit, he said natural gas I said no. Finally he says there are flames coming out of the top of my HP. Turns out the start thermister [I call them blasting caps now ] caught the unit on fire.

Put the phone away and grab the backpack dummy.
And the disconnect is near the flames. Hope the breaker was off or tripped.
