We had a new furnace installed about 4 months ago. About 2-3 weeks ago I had to call because we had no hot water. They came and said it needed restarted. Worked fine e fir a few days but has done it twice since then and my husband restarted it. So I may need to have them back again. S little disappointed in s brand new furnace installation. The guys are very nice. They did come back later that same day to see if it was still working.
