What is a key aspect of evaluating a home heating system?

A key aspect of evaluating a home heating system is checking the installation quality. Proper installation is crucial for the efficient and safe operation of heating systems. If a system is not installed correctly, it can lead to a variety of issues such as inefficient heating, safety hazards like gas leaks, and increased energy costs. An inspector will look for signs that the system has been installed according to the manufacturer's specifications and local building codes. This ensures that the heating system will operate effectively and reliably, providing comfort while minimizing potential risks to the home's occupants.

Considering other factors like the age of the furnace is important, but it does not cover the immediate operational integrity of the system. The aesthetics of the heating system may be visually appealing, but they do not contribute to its functionality or safety. Reviewing utility bills can provide insights into the system's energy efficiency, but these figures cannot replace an on-site assessment of how well the system is installed and operating in real-time. Therefore, installation quality remains a primary focus during a thorough evaluation of heating systems.
