Q: What does 96% AFUE mean?
A: 96% AFUE means 96% of the furnace fuel is converted into usable heat, delivering high‑efficiency heating with lower natural gas costs.
Q: What are the key features of the included evaporator coil (CHPTA1822B3)?
A: The horizontal coil is optimized for R32 refrigerant, has an all‑aluminum design, and a factory‑installed TXV, which improves cooling efficiency and system responsiveness.
Q: What refrigerant does the system use?
A: This system uses R32 refrigerant, a modern, more efficient refrigerant with lower environmental impact.
Q: What installation orientation does it support?
A: It’s designed for horizontal left‑or‑right installation, suitable for attics, closets, or compact mechanical spaces.
Maintenance Tips
-
Replace Air Filters Every 1–3 Months: Maintains airflow, protects furnace and AC components, and ensures efficient operation.
-
Keep Vents & Registers Clear: Ensure supply and return vents are unobstructed for consistent heating and cooling.
-
Clean Outdoor AC Condenser: Rinse coils every 3–6 months to maintain SEER2 performance and prevent debris buildup.
-
Annual Professional Inspection: Have a certified technician check burners, heat exchanger, gas pressure, and airflow for safe and efficient furnace operation.
-
Inspect Refrigerant Lines & Insulation: Ensure lines are intact and insulation is in good condition for optimal R32 efficiency.
-
Maintain Condensate Drains: Keep furnace and AC drain lines clear to prevent water issues or system shutdowns.
-
Schedule Yearly Professional Service: Inspect electrical connections, airflow, and overall system performance.
-
Monitor for Unusual Signs: Strange noises, odors, or inconsistent heating/cooling require prompt professional attention.
