2026 Sustainable Energy Program
LES lists a $1,000 incentive for an air-source or mini-split heat pump under 5.4 tons when it meets the rating or inverter requirements. Geothermal heat pump incentives range from $1,000 to $1,800 depending on EER and a desuperheater.
Who may qualify
The 2026 program applies to new and existing non-mobile residential buildings in the LES service territory. Funds are available January 1 through December 31, 2026 on a first-come, first-served basis or until expended.
Equipment rules
For air-source and mini-split systems, equipment must be AHRI rated and meet either EER2 of at least 12.0 plus SEER2 of at least 15.2, or be inverter-driven or variable-capacity with manufacturer documentation. A mechanical permit is required.
Contractor rule
LES asks customers to review participating contractors, obtain bids, and sign a quote with the selected contractor. A non-participating contractor requires instructions from LES before applying.
How to apply
After the customer signs a qualifying quote, the participating contractor submits the project to LES. The customer receives an LES credit on the contractor invoice after authorization.
Pre-approval
Pre-authorization is required before purchase or installation for qualifying incentives exceeding $5,000. LES strongly advises pre-authorization for other projects because funds are limited and reserved first-come, first-served.
Timing and funding
Projects without pre-authorization must be submitted to LES within 90 days of the invoice date. The 2026 fund window runs through December 31, 2026 or until funds are exhausted.
Documents to keep
AHRI certificates are required in all cases and the installed model numbers must match the certificate. Manufacturer documentation is also required when qualifying through the inverter-driven path.
Next review: Review monthly while the 2026 incentive balance remains available.
