It is very unlikely for most of us to listen to what our ac units or the furnaces tell us. Well, they are not humans, and to expect that they can actually talk is us being foolish. But, this thought is partially true. If you actually lend an ear to your furnace and hear some strange noises which are not normal, then it is time for you to consider a furnace repair in Staten Island. Well, there can be any issue with the furnace, but there is one that needs to be taken a look into without any second thoughts. That is called short cycling. Short cycling means the furnace turns on and off very quickly, and this needs to be taken into account without any delay.
