If it is too large, it will have to move even more air, creating chilly drafts. A heat pump has to move more air around in order for it to maintain even temperatures. This often happens when an AC system is too large.ĭuring the heating season (winter), comfort is impacted by oversized mechanical systems as well, especially with heat pumps. Relative humidity levels in residential houses should be around 50% in the cooling season (summer) for the Chicago area if you have higher levels, it could indicate a problem. Deliver Year-Round Comfort & Better Structural Durability An accurate and efficient system will run steadily without stopping and starting for better comfort and lower utility costs. And let’s not forget the bigger price tag for the unit itself and the subsequent operating costs for the larger fan and compressor.
