The answer to 'inspection not heating' is that the most common causes are a malfunctioning thermostat, a problem with the heating system itself, or issues with the ductwork or airflow. Symptoms may include the system not turning on, the home not reaching the set temperature, or uneven heating throughout the house.
Some potential solutions include checking the thermostat settings, replacing the air filter, and inspecting the heating system components like the furnace or heat pump. However, it's generally best to call a professional HVAC technician to diagnose and repair the issue, as improper DIY repairs can be dangerous or lead to further damage.
