Frequently Asked Questions

• What size (tonnage) packaged straight cool unit do I need for my home?

  A Manual J load calculation by a licensed HVAC contractor is best. As a rough guide, many homes need about 400-600 sq. ft. of conditioned space per ton.

• What is the difference between R-410A and R-454B refrigerants for these package units?

  R-454B has a lower global warming potential than R-410A and is an A2L (mildly flammable) refrigerant. Performance is comparable; local codes and installer readiness may guide your choice.

• Are these 13.4 SEER2 packaged ACs eligible for any rebates or incentives?

  Some utilities offer incentives, but they vary by region and program. 13.4 SEER2 meets federal minimums; check local utility requirements for packaged AC eligibility.

• Can the electric heat strip provide primary heat or is it intended for backup/emergency heat?

  It can serve as primary heat in warm climates, but it’s typically used as supplemental or emergency heat due to higher operating costs versus heat pumps or gas heat.

• What are the installation requirements for horizontal airflow packaged units?

  Require a curb or slab, proper clearances, sealed supply/return ducts, condensate management, and a dedicated electrical disconnect. Professional installation is required.

• How do EcoTemp and Goodman packaged straight cool units compare in features and warranty?

  Both offer dependable value and 13.4 SEER2 performance. Features and limited warranties vary by model-your contractor can match options to your project and budget.

• What electrical and breaker requirements are typical for these package AC units?

  Most residential models use 208/230V single-phase power. Breaker size depends on tonnage and heat strip kW; always follow the unit nameplate and electrical code.

• Can these units be used for light commercial applications like small offices or shops?

  Yes. They are well-suited for small offices, retail, and similar spaces. Verify airflow, curb compatibility, and controls with your installer.

• Can these replace older packaged AC units one-for-one?

  Often yes. Check dimensions, curb or slab, duct transitions, electrical capacity, and thermostat compatibility. The refrigeration circuit is self-contained, easing changeouts.

• How do I choose the right electric heat strip size?

  It depends on climate, heat load, and available electrical capacity. Your HVAC contractor will size the kW strip to meet design heat needs safely.
