REPAIR OR REPLACE?
A Problem With the System Doesn't Automatically Mean You Need a New One.
Some HVAC problems can be repaired. Other situations may make replacement more practical based on the equipment's condition, reliability and repair needs.
Repair May Make Sense When:
- The problem is isolated to an individual part or component
- The system has otherwise been reliable and maintained
- A specific electrical or mechanical component has failed
- Repair remains practical for the equipment's overall condition
Replacement May Make Sense When:
- Repairs are becoming frequent and mounting in cost
- The system is struggling to keep the home comfortable
- Major components are deteriorating
- Continued repairs are no longer practical
