I am a skilled professional that works for a Central Comfort company. I recently completed an annual preventative maintenance on an Amana Forced hot air Furnace. This maintenance involved inspecting the furnace for any signs of wear or damage, cleaning the burners, checking the thermostat, and replacing the air filter. I also tested the furnace's ignition system and combustion air supply to ensure they were working properly. After completing the maintenance, I provided the customer with a detailed report of my findings and recommendations for any necessary repairs or replacements.
