Great job on work very knowledgeable about heating. Had other companies come to try to fix my issue telling me that the furnace needed a new board that would be anywhere from 500to 600 bucks. So i found the same board on Amazon for 180 had a havac certified friend replace it. Still had issue. Waited till winter to come this year and finally decided to try a new place called jubilee heating and cooling was here in bout 2 hrs after I called them. Couple hrs later problem was fixed. Future heating and cooling issues I will definitely be calling them back (if needed). Would recommend to anyone 5 stars and thanks John!!
