An HVAC system can develop numerous problems due to normal wear and tear that can affect energy efficiency. Resolving such a problem might require several repairs being performed, and you might even need to replace the system altogether. However, sometimes HVAC problems can appear to be more severe than they actually are, which is why getting a professional inspection performed is in your best interest. You can actually get a good idea of what is wrong with the system based on the types of problems that it has, such as being able to produce heat but not cold air.
