This usually costs about $100. Ideally, you’ll have done this already. But if not, it’s not too late to call an HVAC company to give it a change-of-seasons inspection, even if your heater’s already been running this season. Your technician will perform a complete inspection and tune-up of your system that will help keep it operating smoothly. Plus, if you catch developing problems early enough, you can often solve them at a much lower cost than if they trigger a major breakdown.
Don’t forget to replace your filters at regular intervals, either. They play a big role in energy efficiency and operations.
