Guidelines for Commercial HVAC Equipment Rebates

The following guidelines must be met before a CPS Energy rebate can be approved and processed:

  • Any reduction in HVAC/Heating usage will be paid based on the current HVAC Rebate Matrix.  
  • All rebate applications are subject to the general provisions including a site visit from CPS Energy personnel after completion of the project.
  • Customer must move to an air conditioning system with a minimum Step 1 efficiency listed in the current HVAC Rebate Matrix.
  • The efficiency is based on the total system efficiency as verified by CPS Energy.
  • Rebates will be based on the nominal tonnage of the new system rounded to the nearest ½ ton (6,000 BTUH).
  • The rebate is based on the difference between the efficiency of the system installed and the minimum efficiency required.
  • The application must include performance specifications at ARI conditions, model numbers and serial numbers for all air conditioner units.
  • HVAC, Packaged Terminal Air Conditioners (PTAC) and Packaged Terminal Heat Pumps (PTHP) Eligible systems must be over 5 tons total or a three-phase unit, regardless of size. 
  • Residential units can be installed to achieve a higher efficiency, but the total installed must be over 5 tons.
  • Packaged Terminal Air Conditioners (PTAC) and Packaged Terminal Heat Pumps (PTHP) are eligible, but the total installed must be over 5 tons.
  • Totals less than or equal to 5 tons will be covered under the CPS Energy Residential Air Conditioner Rebate Program.
  • No rebate is available when moving from a water-cooled chiller to an air-cooled chiller.
  • The $50,000 cap on rebate credits has been eliminated.  The new cap will be “no more than 50% of the total project cost.” 
  • Rebates are also available for geothermal heat pump units.  The amount of the rebate will be $400/ton.  There is no minimal tonnage requirement. When applying for the rebate, use the “custom” designation for the type of rebate on the application.
