Safety boundary: Any current safety defect takes priority over the planning timeline.
Inventory
List equipment type, model, serial, age, fuel, capacity, warranty, service history and known defects.
Identify dependencies
A furnace and air conditioner share a blower and coil. Electrification can affect the panel. Water-heater changes can affect venting shared with a furnace.
Sequence projects
Envelope improvements can reduce equipment loads. Roof or renovation work may affect vent routes and outdoor-unit locations.
Build a reserve
Obtain planning quotes before failure, update them periodically and maintain a dedicated reserve rather than relying on emergency financing.
Useful questions to record
- Is the scope written and comparable?
- Who obtains permits and performs specialized work?
- What testing, commissioning and documentation are included?
