Daikin CHPT/CHPTA Horizontal “A” Cased Coil

Features & Benefits

Here are the key features of the CHPT/CHPTA (with relevant SEO/LSI keywords like “horizontal A coil”, “cased evaporator coil”, “all-aluminum coil”, “factory TXV indoor coil”) and how they benefit your clients:

• Internal Factory‐Installed TXV for Cooling & Heat Pump Use
  The CHPT/CHPTA models include a built-in thermal expansion valve, simplifying installation and optimizing refrigerant control for matched outdoor units.

• All-Aluminum Evaporator Coil
  The coil uses aluminum tubing and fins throughout, offering enhanced corrosion resistance and durability compared to older mixed-metal designs.

• Horizontal “A” Cased Cabinet Design
  Built for horizontal airflow (side-to-side) orientation, making it ideal for attic or crawl-space installations where vertical duct routing is impractical.

• 21″ Depth & Service-Friendly Cabinet
  Many models support a 21-inch nominal cabinet depth for easier attic or tight-space access, foil-faced insulation to reduce condensation, rust-resistant thermoplastic drain pans, and front access panels (on CHPTA) for maintenance convenience.

• Check Flowrater & Rifled Aluminum Tubing
  The series includes “Check Flowrater” metering (for cooling & heat-pump applications) and rifled aluminum tubing with corrugated aluminum fins—designed to improve performance and durability.

• Durable Cabinet & Finishes
  Features include galvanized steel cabinet with leather-grain embossing, foil-faced insulation, and thermoplastic drain pans with secondary drains. These features support longer life and better performance in challenging environments.

Warranty & Registration

• The CHPT/CHPTA series is backed by a 12-Year Parts Limited Warranty, provided the unit is installed by a certified contractor, registered online (within 60 days in most regions) and annual professional maintenance is performed.

• At TopCare HVAC of Oakville, we handle warranty registration and ensure your installation meets all manufacturer and regional requirements, giving you peace of mind.

Installation, Maintenance & Repair (Oakville)

Professional Installation:

• We begin with accurate heating & cooling load calculations to ensure correct coil size and match with the outdoor unit.

• Install the CHPT/CHPTA coil in the correct horizontal orientation (type “A” airflow), ensure proper return and supply duct alignment, clearances and cabinet orientation.

• Connect refrigerant lines, install condensate drain pans and lines, ensure mechanical access, seal cabinet and ducts per code.

• Commission the system: verify airflow, refrigerant metering (TXV), and performance of indoor coil and matched outdoor unit.

Preventive Maintenance:

• At least once annually (or more often in homes with high usage, pets, heavy dust or attic installations):

  • Replace or clean air filters

  • Inspect coil surface for dust/debris, clean as necessary

  • Check drain pan and condensate lines for blockage or overflow

  • Inspect cabinet for insulation damage, condensation or air-leaks

  • Verify matched outdoor unit performance, check for fault codes (if system is communicating)

Repairs & Troubleshooting:

• Diagnose issues such as low cooling capacity, icing, high superheat, low airflow: check TXV operation, airflow, coil cleanliness and match with outdoor unit.

• Inspect cabinet/drain pan for water leaks or corrosion (especially in attic installations).

• Use genuine Daikin parts and adhere to manufacturer service protocols to preserve performance and warranty.

Frequently Asked Questions (FAQs)

Q: What does “horizontal ‘A’ coil” mean for CHPT/CHPTA?
A: “Horizontal ‘A’” refers to side-to-side airflow in a cased coil cabinet, as opposed to up-flow or down-flow models. It’s designed where vertical duct routing is not suitable.

Q: Why should I pick an all-aluminum evaporator coil?
A: All-aluminum coils offer improved corrosion resistance, lighter weight and potential longer lifespan, especially useful in high-humidity, attic or coastal installations.

Q: Can this coil be used with a heat pump system?
A: Yes—since the CHPT/CHPTA includes factory TXV metering and is designed for both cooling and heat-pump applications when matched correctly.

Q: How often should the coil be serviced to keep warranty valid?
A: At minimum once per year; more frequent maintenance may be required in homes with pets, heavy dust, attic usage or humid environments. Correct maintenance preserves performance and warranty coverage.
