Should I run my blower continuously?
Years ago, it was common for contractors to recommend this practice. Over time, we have found that operation your blower can re-evaporate moisture from evaporator coils and drain pans. This can cause humidity problems in the house. There are still some advantages to operating you blower continuously such as evening out temperature imbalances (which may need to be addressed another way) and improved filtration. Generally, we no longer recommend this practice except for in rare circumstances.
