Yes, that’s true, this is our recommendation for your heating maintenance. The reason we suggest this is because it gives our techs a chance to thoroughly inspect, adjust, and clean your system before you need it the most. We also recommend that you have air conditioning maintenance done in the spring for the same reason.

When you live in a climate like ours, you need quality HVAC systems year-round—an efficient and effective air conditioner in the summer, and a powerful heater in the winter. You need each of these systems to work flawlessly, to boot.
