// Bottom Line
This Goodman vertical cased coil is ideal for contractors upgrading existing systems where space is tight and efficiency matters. The 16 SEER1 rating and Energy Star certification make it a solid choice for homeowners seeking lower utility bills without premium pricing.

Review

The Goodman 5-ton vertical cased A-coil represents a practical middle ground in the residential cooling market. This SKU LS38783850 unit delivers proven Goodman reliability with modern R410A refrigerant compatibility. The 35.5-inch width and depth make it genuinely space-efficient compared to traditional designs, while the 38.25-inch height fits most standard utility closets and equipment rooms. It's positioned for contractors who need dependable performance without excessive cost or complexity.

Performance metrics tell a straightforward story. The 54,000 BTU capacity handles 5-ton cooling loads competently, while the 16 SEER1 efficiency rating qualifies for Energy Star certification. The scroll compressor operates at 73 dB on single-stage cycling, meaning it runs full capacity or off with no middle ground. At 208/230V single-phase, it requires a 50-amp maximum breaker and 29.6-amp minimum, making electrical integration straightforward in most homes. These specs deliver solid real-world performance without cutting-edge technology.

Pros & Cons

Pros

  • 16 SEER1 efficiency rating with Energy Star certification reduces cooling costs significantly
  • Compact A-coil design fits upflow or downflow applications in tight mechanical spaces
  • 54,000 BTU output handles 5-ton capacity across mid-sized homes efficiently
  • Scroll compressor technology delivers quiet operation at 73 dB with single-stage reliability
  • R410A refrigerant compatibility ensures alignment with modern HVAC systems

Cons

  • 16 SEER1 rating lags behind newer two-stage compressor models reaching 18+ SEER
  • Single-stage operation means constant full-capacity cycling rather than variable speed modulation
  • 73 dB noise level is noticeably louder than premium variable-capacity units

Who Should Buy

Best For

Contractors managing mid-sized residential replacements in homes with limited equipment space will appreciate this coil's compact dimensions and straightforward installation. Budget-conscious homeowners upgrading from 10-13 SEER systems gain meaningful efficiency improvements without financing premium models.

Consider Alternatives If

Homeowners in extremely hot climates seeking maximum dehumidification or those prioritizing whisper-quiet operation should explore variable-capacity alternatives with higher SEER ratings.

Frequently Asked Questions

How does 16 SEER1 compare to newer high-efficiency models? +
16 SEER1 is solid mid-tier efficiency that cuts cooling costs roughly 35-40 percent versus older 10 SEER units. Variable-capacity models hit 18+ SEER but cost significantly more. For most homeowners, 16 SEER provides excellent return on investment without premium pricing, delivering real utility savings over the 10-year warranty period.
Will this coil fit my existing outdoor condenser unit? +
Compatibility depends on your condenser tonnage and refrigerant type. This is a 5-ton unit using R410A refrigerant. Verify your condenser is also 5-ton R410A equipped. Contact the manufacturer with your condenser model number. Mixing ton ratings or refrigerant types causes serious efficiency loss and potential compressor damage.
What does the 73 dB noise level mean practically? +
73 dB equals a busy office or vacuum cleaner volume. It's noticeable but not loud by HVAC standards. For perspective, premium variable-capacity units operate 3-5 dB quieter. If noise sensitivity matters, consider higher-end equipment. Most homeowners find 73 dB acceptable, especially when the unit cycles intermittently.
Can I use suction lines longer than 50 feet? +
The specs indicate 50-foot maximum length for 7/8-inch suction lines with 3/4-inch insulation. Exceeding this distance increases pressure drop and reduces efficiency significantly. If your installation requires longer runs, specify larger suction line diameters or consult Goodman engineering for custom configurations.
Does online registration affect warranty coverage? +
Yes, online registration is required to activate the full 10-year warranty. Without registration, coverage drops to shorter periods. Registration is quick and free through Goodman's website. Always complete this step immediately after installation to protect your investment.
