Frequently Asked Questions (FAQs)
Q: What does R-32 mean for this coil?
A: R-32 is a modern, lower-GWP refrigerant. The CAHEA R-32 series is designed with circuits and sensors optimized for R-32 systems.
Q: Can I use this coil with my existing outdoor unit?
A: Only if the outdoor unit is designed for R-32 refrigerant and matches the system capacity. Always consult a certified technician to avoid performance issues and voided warranty.
Q: What does upflow/downflow mean?
A: Upflow draws air from below and discharges from the top; downflow does the opposite. CAHEA supports both for flexible installations.
Q: How often should maintenance be performed?
A: At least annually; more frequent service is recommended in homes with pets, dust, or high humidity to maintain efficiency and warranty coverage.
