Common Questions

How often should HVAC be serviced?

Once a year for a furnace or an AC. Twice a year for a heat pump or any system that runs year-round.

Is an HVAC maintenance plan worth it?

For most people, yes. A plan usually costs about the same as two tune-ups, and the repair discounts and priority scheduling come with it.
