When heat pumps are improperly sized, they typically do not operate efficiently, leading to increased energy costs. An oversized heat pump may cycle on and off too frequently, which can cause wear and tear on the system and lead to insufficient humidity control, reducing overall comfort. Conversely, an undersized heat pump may struggle to maintain the desired temperature, causing it to run continuously and overwork the system. Both scenarios result in inefficiency, which ultimately translates to higher energy bills for the homeowner.

In a well-sized heat pump, the unit operates smoothly and efficiently, maintaining the desired indoor climate without unnecessary energy expenditure. Thus, the consequence of improperly sizing heat pumps is a clear path to inefficiency and increased energy costs.
