What is a Variable Refrigerant Flow (VRF) system?

A Variable Refrigerant Flow (VRF) system is a type of HVAC system that uses refrigerant as the cooling and heating medium and allows for individual temperature control in different zones. They offer precise temperature control and enhanced comfort. A qualified HVAC professional can help determine if a VRF system is right for your business.

When should I consider upgrading my commercial HVAC system?

Consider a commercial HVAC upgrade if:
  • Age: If your system is 15-20 years old or older, it is likely to be less efficient and more prone to breakdowns.
  • Frequent Repairs: If you're constantly calling for repairs, a new system may be more cost-effective in the long run.
  • Rising Energy Bills: An inefficient system can lead to increased energy consumption.
  • Inconsistent Temperatures: Uneven temperatures can be a sign of an improperly sized or poorly maintained HVAC system.
  • Poor Indoor Air Quality: A new system can improve ventilation, filtration, and humidity control to address indoor air quality issues.
  • Refrigerant Changes: If your system uses an outdated refrigerant that is being phased out, an upgrade might be required to comply with new regulations.
Consult with a reputable HVAC contractor to determine if a system upgrade is the best solution for your needs.
