If your heating and cooling system has always under-performed in terms of energy efficiency, then it is possible that your system was not installed properly or that it is not of the right size for your home. In such instances, considerable work may be necessary, including investing in a properly sized system, in order to attain the efficiency levels that you hope for. If your energy efficiency was fine, though, and has been slipping over time, there may be a number of factors at play which can be addressed with less drastic measures.
Should you use a forced air distribution system in order to deliver conditioned air throughout your home, then it may be your ductwork that is the problem. If your ducts have developed leaks and tears, or if connections have loosened, they may allow conditioned air to escape the system. This can lead to considerable energy loss and seriously reduced efficiency.
Additionally, it is possible that dirty ductwork is to blame. No, it is not very likely that pollutants will build up to the point that they are blocking off a section of your ductwork. However, these pollutants can overwhelm air filters in your system, increasing airflow resistance and causing your system to work harder. Also, dirt and dust can build up on vital components in your system, causing a drop in efficiency as well.
It is even possible that your thermostat is not functioning properly, failing to cycle your system off and on appropriately. The fact of the matter is that any number of issues can cause a drop in efficiency, and only a pro can diagnose and resolve the problems successfully.
