Daikin CHPT/CHPTA Horizontal “A” Cased Coil

Features & Benefits

Below are the standout features of the Daikin CHPT/CHPTA series—often searched as a horizontal A-coil, cased evaporator coil, all-aluminum indoor coil, or factory-TXV evaporator—and how they enhance system performance and long-term reliability:

• Factory-Installed Internal TXV for Cooling & Heat Pump Systems
  Each CHPT/CHPTA evaporator coil comes equipped with an internal thermal expansion valve, allowing for precise refrigerant metering, improved efficiency, and simplified installation when paired with compatible outdoor AC or heat pump units.

• All-Aluminum Evaporator Coil Construction
  Built entirely with aluminum tubing and fins, this coil design delivers superior resistance to corrosion while reducing weight and increasing durability compared to traditional copper-aluminum combinations.

• Horizontal “A” Style Cased Configuration
  Designed specifically for side-to-side airflow, the horizontal A-coil cabinet is well-suited for attic, crawl-space, or low-clearance installations where vertical airflow is not feasible.

• Compact 21-Inch Cabinet Depth with Service-Friendly Design
  Select models offer a 21-inch nominal depth to ease installation in confined spaces. Features include foil-faced insulation to minimize condensation, rust-resistant thermoplastic drain pans, and convenient front access panels on CHPTA models for maintenance.

• Check Flowrater Technology & Rifled Aluminum Tubing
  Integrated Check Flowrater metering supports both cooling and heat pump operation, while rifled aluminum tubing and corrugated fins help improve heat transfer efficiency and long-term performance.

• Robust Cabinet Materials & Protective Finishes
  The galvanized steel cabinet features a leather-grain embossed finish, foil-faced insulation, and dual thermoplastic drain pans with secondary drains—enhancing durability and reliability in demanding installation environments.

• Our technicians connect refrigerant lines, install condensate drainage components, seal all cabinet and duct connections, and ensure compliance with local building codes.

• System commissioning includes airflow verification, TXV operation checks, refrigerant performance testing, and confirmation of proper indoor-outdoor system matching.

Preventive Maintenance

• Recommended at least once per year—or more frequently in homes with pets, higher usage, attic installations, or dusty environments:

  • Replace or clean air filters

  • Inspect and clean the evaporator coil as needed

  • Check condensate drain pans and lines for clogs or leaks

  • Examine cabinet insulation for moisture, damage, or air leakage

  • Verify outdoor unit operation and system communication (where applicable)

Repairs & Troubleshooting

• We diagnose issues such as reduced cooling output, coil icing, improper superheat, or airflow problems by inspecting TXV function, coil condition, ductwork, and outdoor unit compatibility.

• Cabinet integrity and drain pan condition are checked for water damage or corrosion—especially in attic-mounted systems.

• All repairs use genuine Daikin replacement parts and follow manufacturer service procedures to protect efficiency and warranty coverage.

Frequently Asked Questions (FAQs)

Q: What does “horizontal A-coil” mean for the CHPT/CHPTA?
A: A horizontal A-coil is designed for side-to-side airflow within a cased cabinet, making it ideal for installations where vertical ducting isn’t possible.

Q: What are the benefits of an all-aluminum evaporator coil?
A: All-aluminum coils are lighter, more corrosion-resistant, and often longer-lasting—especially in humid conditions or attic installations common in Mississauga homes.

Q: Is the CHPT/CHPTA compatible with heat pump systems?
A: Yes. With a factory-installed TXV, this coil is engineered for both air conditioning and heat pump applications when properly matched.

Q: How often should servicing be done to maintain warranty coverage?
A: Annual professional maintenance is the minimum requirement, with more frequent servicing recommended for high-use or challenging environments.
