I performed a comprehensive maintenance service on the gas furnace, ensuring it was ready for the upcoming winter and spring seasons. This included replacing the air filter with a new one to enhance indoor air quality. I meticulously checked for any gas leaks and carbon monoxide levels to ensure safety. Additionally, I inspected the air conditioning system, focusing on the outdoor compressor. I tested the fan motor for proper operation and checked refrigerant levels to ensure efficient cooling. The condensing unit was cleaned to remove any debris, which helps maintain optimal performance. All components were thoroughly examined and tested to ensure the systems operate safely and efficiently.
