Air conditioning tips missed mark
In response to your front page article dated Aug. 4th, there were errors on "Help your house beat the heat" tips.
It read that insufficient air flow from a central air conditioning system can cause freezing of the condenser coil. Wrong. Poor air flow may cause freezing of the evaporating coil which is affixed to the furnace.
Secondly, the recommendation of monthly filter changes is typically unnecessary. A periodic inspection of clogging should necessitate the purpose of replacement.
A better tip should have been to go outside and inspect your air conditioning unit. While operating, the larger insulated pipe from your home should be sweaty cold. If not, it could be a sign of refrigerant shortage which creates prolonged operation and potential system damage.
