When to Schedule Furnace Maintenance
We recommend having your furnace serviced once a year, ideally in the fall before temperatures drop. This ensures everything is running smoothly when you need it most.
If it’s been more than 12 months since your last tune-up — or if you’re noticing uneven heating, rising energy bills, or strange sounds — now’s the time to schedule.
