2026 Energize CT rebate guide
Connecticut publishes a $250-per-ton standard air-to-water offer and a $1,000-per-ton Energy Optimization path, with enhanced incentives up to $1,500 per ton for certain verified projects.
Model estimates
The estimates apply each published per-ton formula to reviewed regional QPL cooling capacities. The selected pathway depends on the existing heating system and verified project conditions.
| APOLLO model | Program-rated or QPL capacity | Standard estimated rebate | Energy Optimization estimated rebate | Enhanced estimated rebate | Published program cap |
|---|---|---|---|---|---|
| APOLLO 3.5 Ton / 42K BTUAP-EVI-DC-3.5T | 2.30 QPL tons | $575 estimated rebate | $2,300 estimated rebate | $3,450 estimated rebate | $2,500 standard; $10,000 optimization/enhanced |
| APOLLO 5 Ton / 60K BTUAP-EVI-DC-5T | 5.00 QPL tons | $1,250 estimated rebate | $5,000 estimated rebate | $7,500 estimated rebate | $2,500 standard; $10,000 optimization/enhanced |
| APOLLO 6 Ton / 72K BTUAP-EVI-DC-6T | 5.50 QPL tons | $1,375 estimated rebate | $5,500 estimated rebate | $8,250 estimated rebate | $2,500 standard; $10,000 optimization/enhanced |
Every dollar figure is an estimated rebate. Confirm exact model status and tonnage on the current Energize CT QPL. Enhanced electric-resistance estimates can be lower when only part of the system receives the enhanced rate.
Energize CT states that tonnage is based on AHRI cooling capacity divided by 12,000 BTU and rounded under program rules. That value can differ from the APOLLO commercial product name. These estimates use the reviewed regional QPL values and must be rechecked against the live Energize CT list.
Program pathways
The standard, Energy Optimization and enhanced offers serve different project conditions. Pre-verification is especially important for income and electric-resistance enhancements.
$250 per ton, up to $2,500
This path applies to qualifying projects such as replacing an existing heat pump, adding heat to previously unconditioned space or installing for heat without the required integrated controls.
The customer must have eligible Eversource or United Illuminating residential electric service.
$1,000 per ton, up to $10,000
For qualifying projects that fully displace or properly integrate natural gas, oil, propane or electric resistance as the primary heating source.
If inspection finds the project does not satisfy the optimization path, the incentive may be modified to the $250-per-ton standard offer.
Up to $1,500 per ton, capped at $10,000
Certain income-qualified households and verified electric-resistance replacement projects may receive the enhanced rate.
Electric-resistance projects require verification before installation, and the enhanced rate may apply only to the verified portion of the system.
Before you buy
Application roadmap
Determine whether the project qualifies for the standard air-to-water offer, Energy Optimization or an enhanced pathway.
Verify income or existing electric-resistance heat before installation when required for the enhanced offer.
Use a contractor in the Energize CT Heat Pump Installer Network and review the existing-system displacement plan.
Match the complete model to the current QPL and use the program or AHRI cooling capacity for the estimate.
The invoice should identify equipment, capacity, installer and the project information required by the program.
Submit the final paid invoice and cooperate with a post-installation inspection if the project is selected.
Common questions
The path depends on the existing heating system and how it is displaced or integrated. Replacing a primary fossil-fuel or electric-resistance system can qualify for Energy Optimization, while replacement heat pumps and certain other projects use the standard offer.
The table multiplies 2.30, 5.00 or 5.50 reviewed QPL tons by $250, $1,000 or $1,500 and applies the published program cap.
No. Existing electric resistance must be verified before installation, and the enhanced rate can be limited to the portion of the new system that replaces verified resistance heat.
Yes. Energize CT states that a project submitted for the $1,000-per-ton Energy Optimization offer can be modified to the $250-per-ton standard offer if inspection shows the optimization requirements were not met.
