All-Aluminum Evaporator Coil: Built with aluminum tubing and fins for enhanced corrosion resistance and long-term durability.
Optimized for R-32 Refrigerant: The coil, manifolds and sensors are designed to meet the requirements of R-32 refrigerant systems.
Up-flow/Down-flow Configuration Flexibility: Supports vertical direction air flow in either orientation, making installation easier in attics, basements or mechanical rooms.
Compact Depth (approx. 21″) for Easier Attic Access: Many models in the spec sheet list a 21-inch depth to simplify installation in tight spaces.
Service-Friendly Design: Features such as foil-faced insulation to reduce condensation, thermoplastic drain pans with secondary drains, and rust-resistant finishes contribute to low maintenance and durability.
Warranty Protection: Eligible for a 12-Year Parts Limited Warranty (with registration and maintenance) offering peace of mind.
To qualify for the full 12-Year Parts Limited Warranty, the coil must be installed by a certified HVAC contractor, registered online within the required timeframe, and must undergo annual maintenance.
At TopCare HVAC of Oakville, we handle your registration and ensure your installation meets all manufacturer and regional warranty requirements.
Professional Installation:
We start with a full load calculation and ensure correct size and match with the outdoor unit.
Install the CAPFA coil in the correct orientation (up-flow or down-flow) and ensure clearance, proper airflow and duct alignment.
Connect refrigerant lines, secure cabinet in place, ensure correct drain pan slope and condensation drainage.
Commission the system: verify refrigerant circuit, airflow, thermostat control and system performance.
Preventive Maintenance (Recommended):
At least once annually (or more frequently in high usage or dusty/humid environments):
Replace/clean filters
Inspect coil for dust/debris, clean as needed
Check drain pan, secondary drain connections, and verify no water accumulation
Inspect cabinet insulation, seams, ducts for leaks or damage
Review system controls and fault memory if applicable
Repair & Troubleshooting:
Diagnose refrigerant circuit issues (especially if R-32 outdoor unit is mismatched)
Inspect coil for corrosion, leaks or degraded fins
Address drainage issues, check drain pan integrity
Use OEM Daikin parts and follow manufacturer service protocols to maintain system integrity and warranty.
Q: Why choose a coil optimized for R-32 refrigerant?
A: R-32 has a lower global warming potential (GWP) than older refrigerants like R-410A, and coils built for R-32 include compatible manifolds, sensors and metering that help maintain efficient and safe operation.
Q: Can this coil be used with any outdoor unit?
A: No — it must be matched with an outdoor unit designed for R-32 and the correct tonnage. Mismatched systems can lead to poor performance or warranty issues.
Q: How often should maintenance be performed to preserve warranty coverage?
A: At minimum once per year; more frequent maintenance is advised in homes with pets, dust or high humidity. Proper care helps ensure long-term performance and keeps warranties valid.
