I have seen it in the straight lengths and the coil, but should I use?

I went in Wed AM with the glass man, and saw that the stove drip pans and coils were in the sink, so the cleaner had been there.

For example, if the oven coil needs to be replaced, they will replace it for me, charging only for the coil, not for the labor.In your case, I suggest you take care of it as soon as you can.

The gas ranges virtually never wear out like the coils can on electric stoves.

Such heat pumps will provide a COP >1 down into the -5F - 0F range, at that point auxiliary heat - typically electric coil or base boards - kick in to support the heat pump.

So, this is about right.Heat Furnace = $1,400Do you have to replace the compressor or the coil?

Is there a furnace, coil or drip line in the attic above the stain?

You can also use it to wash off the coils if they are dirty, since it won't leave a lasting smell like bleach willl.

My HVAC quote was about 3k for new A coil/heat pump/condenser installed.

It's probably the other way around -- $1000-1500 for furnace and $2000-4000 for A/C compressor and coil.
