Frequently Asked Questions

Retro-commissioning is the process of evaluating and optimizing existing HVAC and Building Automation Systems (BMS) to improve performance, reduce energy consumption, and correct operational issues without replacing equipment.

Most buildings in South Florida see 10% to 30% energy savings after retro-commissioning, depending on system condition, control issues, and existing inefficiencies.

You may need retro-commissioning if:

  • Energy bills are higher than expected
  • HVAC systems run continuously
  • Comfort complaints are frequent
  • Equipment is not operating as designed
  • Your BMS has not been reviewed in years

No. Retro-commissioning focuses on optimizing your existing systems and controls. Equipment replacement is only recommended if necessary.

Most retro-commissioning projects in South Florida take 2 to 8 weeks, depending on building size, system complexity, and scope of work.

Retro-commissioning is ideal for:

  • Office buildings
  • Hotels and resorts
  • Condominiums
  • Hospitals
  • Industrial and pharmaceutical facilities
  • Central plants and district cooling systems

Yes. Chiller plant optimization is one of the biggest opportunities for energy savings. Proper sequencing of chillers, pumps, and cooling towers can significantly reduce energy consumption.

Absolutely. By correcting control issues and optimizing system performance, retro-commissioning improves temperature control, humidity levels, and overall indoor comfort.

Yes. Liable Controls provides retro-commissioning services throughout South Florida, including Miami-Dade, Broward County and Palm Beach County.

Retro-commissioning can be a one-time optimization, but it is most effective when combined with a BMS service agreement to maintain performance over time.
