When each route deserves a closer look

A

Repair

  • The system is otherwise sound
  • The repair is limited and clearly diagnosed
  • Expected remaining life supports the repair cost
B

Replace

  • Failures are recurring or major components are affected
  • Comfort or capacity problems require redesign
  • The full installed scope and warranty are documented
Comparison questions

Keep the assumptions equal.

Is Repair always cheaper than Replace?+

No. Equipment, existing infrastructure, local labor, permits, financing and operating cost must be compared with the same home assumptions.

How should I compare Repair and Replace quotes?+

Give bidders the same home data and require itemized equipment, labor, electrical or fuel work, permits, commissioning, exclusions and warranties.

Test the decision

Move from system type to project economics.

Use identical home, comfort and cost assumptions for both routes.
