Daikin CHPTA (R-32) Cased Horizontal “A” Coil

Features & Benefits

Here are the key features of the CHPTA (R-32) coil (with SEO/LSI keywords like “horizontal coil”, “all-aluminum evaporator”, “R-32 compatible indoor coil”, “factory TXV evaporator coil”) and how they benefit your customers:

• All-Aluminum Evaporator Coil
  The CHPTA uses aluminum tubing and fins throughout — improving corrosion resistance and durability compared to older mixed-metal coils.

• Optimized for R-32 Refrigerant
  Built for the modern, lower-GWP refrigerant R-32: circuits, manifolds and sensor layout are engineered for this refrigerant.

• Factory-Installed Thermal Expansion Valve (TXV)
  Ensures precise refrigerant metering for either cooling-only or matched heat-pump applications — enhancing both efficiency and reliability.

• Horizontal “A” Cased Cabinet Design
  Designed for horizontal airflow (side-to-side) in environments where vertical airflow may not fit — ideal for attic runs, crawl spaces or wide-return ducts.

• 21-inch Depth & Service-Friendly Features
  The cabinet depth is designed at approximately 21″ for easier installation in attic or tight spaces; features like foil-faced insulation and a single-front access panel improve serviceability.

• High-Quality Cabinet Finish & Drain Pan
  Galvanized, leather-grain-embossed cabinet finish; rust-resistant thermoplastic drain pans with secondary drain connections and low water-retention design for longer life.

Warranty & Registration

• The CHPTA (R-32) is backed by a 12-Year Parts Limited Warranty, provided installation is done by a qualified contractor, registration is completed (typically within 60 days of installation), and annual maintenance is performed.

• At TopCare HVAC of Oakville, we ensure your system is registered and installation meets all manufacturer and Canadian/Ontario requirements, preserving your warranty coverage and ensuring long-term support.

Installation, Maintenance & Repair (Oakville)

Professional Installation

• We perform an accurate cooling/heating load calculation to select the correct CHPTA model and ensure proper match with the outdoor unit.

• Install the indoor coil in the correct horizontal orientation (type “A”), confirming ductwork return/supply alignment, clearances and service access.

• Connect refrigerant lines, install proper drain pan and secondary drainage, ensure cabinet sealing and insulation, and verify airflow and static pressure.

• Commission the system: verify correct refrigerant charge (or match per manufacturer when paired with inverter/heat-pump unit), verify TXV operation, check airflow, ensure thermostat/control integration.

Preventive Maintenance

• At least once a year (or more frequently in higher dust/humidity or attic installations):

  • Replace or clean air filters

  • Inspect the evaporator coil for debris, clean as necessary

  • Check drain pan and condensate line for blockages or water retention

  • Inspect cabinet insulation, check for condensation and sealing integrity

  • Verify matched outdoor unit performs well, no refrigerant issues/dips in capacity

Repairs & Troubleshooting

• If the system under-performs (low cooling, high superheat, restricted airflow): check the coil cleanliness, airflow static pressure, correct match of outdoor unit, and TXV performance.

• Address drainage issues (overflow, pan leaks) which can cause water damage and reduce coil efficiency.

• Use genuine Daikin replacement parts to maintain system integrity and warranty eligibility.

Frequently Asked Questions (FAQs)

Q: Why choose a horizontal “A” coil like CHPTA instead of up-flow/down-flow?
A: A horizontal “A” coil is tailored for side-to-side airflow in installations where vertical space is limited (attics, crawl-spaces or mechanical rooms with horizontal return/exit runs). The CHPTA series is specifically designed for this orientation.

Q: What are the advantages of R-32 refrigerant compatibility?
A: R-32 offers significantly lower Global Warming Potential (GWP) compared to older refrigerants like R-410A, while maintaining efficient heat transfer. Using a coil optimized for R-32 ensures compatibility with modern outdoor units and future-proofing.

Q: Can this indoor coil be used with any outdoor unit?
A: Only if the outdoor unit is properly matched in capacity, refrigerant type (R-32 in this case), line sizing, and airflow conditions. Mismatched indoor/outdoor pairing can lead to inefficiency or void warranty. Always consult a certified HVAC contractor.

Q: How often should the coil/system be serviced to maintain warranty eligibility?
A: At minimum once a year. In homes with heavy use, pets, high dust, or installations in attics/crawl‐spaces, more frequent servicing is recommended to maintain performance and warranty validity.
