Features
3 ton horizontal evaporator coil
Can be used with heat pump and AC-only condensers
R32: Complies with Clean Air Act New Refrigerant Requirements
Galvanized, embossed, and insulated coil cabinet to protect the coil and prevent air leakage
Purpose‑Built for R‑32 Systems The Goodman CHPTA3630B3 is engineered for R‑32 refrigerant central HVAC systems, meeting modern environmental standards and cooling performance needs in residential applications.
Factory‑Installed Thermal Expansion Valve (TXV) A built‑in TXV ensures precise refrigerant metering, improving system efficiency, temperature stability, and humidity control compared with fixed‑orifice coils.
Durable All‑Aluminum Coil & Rust‑Resistant Features The all‑aluminum coil resists corrosion, boosts heat transfer, and extends service life, while the rust‑resistant thermoplastic drain pan and foil‑faced insulation help minimize condensation and mold risk.
Installer‑Friendly Horizontal Design With a 17.5″ height and horizontal orientation, this coil fits well in attics, crawl spaces, and horizontal furnace setups — ideal for space‑constrained installations.
Easy Service & Maintenance Access A single front access panel and split‑seam cabinet make inspection and servicing easier for technicians, saving time and labor.
Q&A
Q1: What HVAC systems is this evaporator coil made for? A: The Goodman CHPTA3630B3 is designed for 2.5–3 ton split‑system air conditioners and heat pumps, ideal for residential cooling applications.
Q2: Does this coil include a TXV meter? A: Yes — it features a factory‑installed TXV (Thermostatic Expansion Valve) for precise refrigerant flow control and improved efficiency.
Q3: What refrigerant does this unit support? A: It’s optimized for R‑32 refrigerant, offering better energy efficiency and lower environmental impact than older refrigerants.
Q4: What are the key physical specs? A: The coil has a 17.5″ height, 30″ width, and 21″ depth (horizontal cased design). External connections include 3/8″ liquid and 7/8″ suction lines.
Q5: What construction features help performance and durability? A: It uses an all‑aluminum coil with foil‑faced insulation to reduce condensation, rust‑resistant thermoplastic drain pans with secondary connections, and a galvanized cased cabinet for rugged indoor protection.
Q6: Is this evaporator coil certified for quality and safety? A: Yes — the CHPTA3630B3 is AHRI certified and ETL listed, ensuring industry‑standard performance and safety.
Q7: Where should this coil be installed? A: It’s designed for horizontal installation, typically in attics, crawl spaces, or closets where horizontal airflow is required.
Maintenance Tips
Replace Air Filters Every 1–3 Months – Clean filters maintain proper airflow across the all‑aluminum coil and prevent coil icing.
Keep the Coil Surface Clean – Dust and debris on the aluminum fins reduce heat transfer; schedule professional coil cleaning annually. (hvacstore.com)
Inspect Condensate Drain & Pan – Ensure the rust‑resistant drain pan and lines are clear to prevent leaks and microbial growth.
Check TXV Operation – The factory‑installed thermostatic expansion valve regulates refrigerant flow; periodic inspections ensure proper superheat and system efficiency.
Maintain Proper Airflow – Keep supply and return vents unobstructed to support consistent airflow through the horizontal A‑coil.
Inspect Cabinet & Insulation – The galvanized, insulated cabinet reduces condensation; check annually for moisture or damage.
Schedule Annual HVAC Service – Professional maintenance helps detect refrigerant issues, clean internal components, and maintain peak performance.
