Frequently Asked Questions

  • Does the $750 Water Heater Rebate Require Me to File Anything?
    No. The instant rebate is applied through the distributor at the point of purchase. Our licensed plumbers handle that process when they order the unit. You receive the savings without having to file a separate rebate form.
  • How Does the HEAT Loan Work Alongside Rebates?

    The HEAT Loan and Mass Save rebates are separate programs, and you apply them in sequence. The rebate reduces the total project cost, and the HEAT Loan finances what remains at 0% interest. Preapproval must be completed before work begins. Our team coordinates both, so neither one slows down your project timeline.

  • Are R-410A Systems Still Eligible for Mass Save Rebates?

    No. Systems using R-410A refrigerant became ineligible on January 1, 2026. Equipment must use R-32 or R-454B refrigerant to qualify. All systems we install meet the current refrigerant requirements.
