Maintenance plans and add-ons

Companies often offer service agreements during a repair visit. Some are useful; read them first.

What the plan includes

Look for the number of tune-ups per year, any repair discounts and whether it gives priority scheduling.

Check whether the plan renews automatically and how to cancel.

You may be offered air purifiers, duct cleaning or other upgrades. These are optional; ask for a separate written price and take time to decide.
