Why This Plano 75025 Homeowner Replaced Their System

The homeowner in Plano 75025 contacted us after experiencing:

• Reduced cooling capacity during peak Texas heat
• Aging Trane system with declining efficiency
• Rising summer utility bills
• Concern about reliability before peak season

After performing a load evaluation and airflow inspection, we recommended a properly matched Goodman high-efficiency straight cool system delivering 15.2 SEER2 performance (AHRI certified) — optimized for Texas cooling demand while maintaining dependable gas heat for winter.

For Plano homeowners, where cooling dominates annual runtime, SEER2 performance is critical for long-term operating cost control.

Installed System Overview

Outdoor Unit – Goodman 24,000 BTU Split Air Conditioner

AHRI Certified 15.2 SEER2 Performance

Key Features:

• Energy-efficient compressor
• Copper tube / enhanced aluminum fin coil (5mm diameter)
• Factory-installed filter drier
• Pre-charged for 15 ft line set
• 10-Year Limited Parts Warranty (with homeowner registration)

Why 15.2 SEER2 Matters in Plano, TX

Plano summers routinely exceed 95°F. Higher SEER2 systems:

• Reduce peak energy consumption
• Improve dehumidification
• Lower strain on compressor
• Decrease long-term utility cost

This system is AHRI certified at 15.2 SEER2, exceeding base federal minimum standards — improving efficiency without the premium cost of inverter systems.

Evaporator Coil – Daikin/Goodman 30,000 BTU Cased Horizontal Coil

Features:

• Factory-installed TXV (Thermal Expansion Valve)
• All-aluminum evaporator coil
• Rust-resistant thermoplastic drain pan
• Rifled aluminum tubing with corrugated fin design
• 10-Year Limited Parts + Unit Replacement Warranty

Why TXV Is Important

The factory-installed TXV allows:

• Precise refrigerant metering
• Better efficiency across varying loads
• Improved humidity control
• Longer compressor life

For humid North Texas conditions, TXV-equipped systems outperform fixed orifice coils.

Gas Furnace – Goodman 60,000 BTU 80% AFUE Multi-Position (Horizontal)

Key Engineering Features:

• Heavy-duty aluminized-steel tubular heat exchanger
• Silicon Nitride Igniter
• Multi-speed ECM blower motor
• Self-diagnostic control board
• 20-Year Limited Heat Exchanger Warranty
• 10-Year Limited Parts Warranty

Why ECM Blower Motor Matters

The ECM blower provides:

• Lower electrical consumption
• Quiet operation
• Continuous fan capability
• Better airflow consistency

Even in single-stage furnaces, ECM motors dramatically improve comfort and energy efficiency.

Engineering-Driven Installation Process (Not “Swap-the-Box”)

At Greentech Engineering HVAC, installation quality determines long-term performance.

Scope of Work Included:

✔ Old Trane system removed and properly refrigerant recovered
✔ New gas sediment trap & Safe-T drain switch installed
✔ New concrete condenser equipment pad
✔ Drain line cleared with pressurized nitrogen
✔ New trap, vent, insulation & modifications
✔ RX-11 line set flush + dry nitrogen purge
✔ 15% silver brazing by certified technician
✔ Pressure tested at 250 PSI (minimum 15-minute hold)
