RIP OFF!!! Be careful.
RIP OFF!!! I'm mechanically inclined and aware of how to fix a furnace so I tore the furnace apart and got to the flame sensor which needed to be replaced, the flame sensor That I had did not fit I was without heat, so I called J&K heating and cooling, that was a mistake. The technician came and did not replace the flame sensor he did clean the flame sensor piece of sandpaper which took less than 10 minutes and left me the sandpaper and basically charged me $110.00 for less than 10 minutes of work to clean a less than $10 part and did NOT even change out the defective flame sensor. $110.00 for less than 10 minutes of cleaning a $10 part and a piece of sandpaper is what I got from J&K heating and cooling RIP OFF of the century.
