When to Schedule Your Seasonal Heating Tune-Up
The optimal time to schedule your annual furnace inspection is early fall before turning your heat on for the first time. However, if your system hasn’t been serviced in over a year, booking a tune-up at any point during the winter helps maintain efficiency and system safety.
