This past winter has been one of the worst we have seen in North Central Ohio for quite a few years. Between the big snowfall in January, the subzero temperatures of the polar vortex, bouts of high wind, and the constant warm-up/cooling we are experiencing, you can bet that almost everyone is looking forward to spring to come around finally. Punxsutawney Phil said we are going to have an early spring, but it isn’t looking that way so far. But it will warm up eventually, and when that happens, you want to make sure your central air conditioning unit is ready to go before you set your thermostat to cool.
