The answer to 'why is my replacement' is that there could be several common causes for a malfunctioning HVAC replacement system. Some of the most frequent issues include incorrect sizing or installation, problems with the ductwork, electrical issues, or a lack of regular maintenance.
If the new HVAC system is not properly sized for your home, it can lead to short-cycling, uneven cooling/heating, and higher energy bills. Improper installation, such as leaky ductwork or electrical wiring problems, can also prevent the system from operating efficiently. Regular tune-ups and filter changes are essential to keep the replacement system running at its best.
