Before you request service

Useful answers for a heating problem.

Should I request a diagnostic or a tune-up?

Choose a diagnostic when the furnace is not heating or is behaving differently. A tune-up is for seasonal maintenance when the system is operating.

What should I note before the visit?

Include what the furnace is doing, when the issue started, any visible error code, and the equipment type if you know it.

Can Fahrenheit Pros help with a repair-or-replace decision?

Yes. A diagnostic can identify the current issue, and free estimate requests are available when replacement or installation is being considered.
