What Is Energize CT? A Homeowner’s Guide to Energy Savings and Insulation Incentives
Saving Money with EnergizeCT

If you own a home in Connecticut, you’ve probably heard someone mention Energize CT, usually right before talking about rebates, insulation upgrades, or cutting energy bills.

And in this state, that matters.

Connecticut consistently ranks among the highest energy-cost states in the country. Long winters. Humid summers. Older housing stock. Drafty attics. Under-insulated walls. It’s the perfect recipe for high utility bills.

So what exactly is Energize CT — and how does it actually help you?

Let’s break it down clearly.

Key Takeaway

If you’re a Connecticut homeowner, Energize CT is the easiest way to stop overpaying for a drafty house. Start with a Home Energy Solutions assessment, use the rebates to upgrade insulation and air sealing first, and lock in a more comfortable home with lower energy bills for the long haul.

What Is Energize CT?

At its core, Energize CT is Connecticut’s statewide energy efficiency program designed to help homeowners reduce energy use through rebates and incentives.

It’s funded by the state’s utility companies — primarily Eversource and United Illuminating (UI) — in partnership with the state.

The goal is simple:

  • Lower energy consumption
  • Reduce strain on the grid
  • Help homeowners upgrade their homes affordably

If your home needs:

  • Attic insulation
  • Wall insulation
  • Air sealing
  • Duct sealing
  • Heat pumps or high-efficiency HVAC

Energize CT may cover part of the cost.

This isn’t a coupon. It’s a structured pathway to improving your home’s performance.

How Does Energize CT Work?

The process is straightforward — if you follow the order.

Energize CT home energy assessment process showing evaluation, recommendations, insulation installation, and incentives.

Step 1: Schedule a Home Energy Solutions Visit

Everything starts with a Home Energy Solutions (HES) assessment.

A certified technician performs diagnostic testing, including:

  • Blower door testing (measures air leakage)
  • Insulation level checks
  • Duct inspection
  • HVAC evaluation

This establishes your home’s baseline performance.

Step 2: Review the Recommendations

After testing, you’ll receive:

  • Identified problem areas
  • Recommended upgrades
  • Available rebates
  • Estimated energy savings

This is where insulation and air sealing often rise to the top.

Step 3: Complete Approved Upgrades

Work is completed by an approved contractor following program standards.

Rebates are often applied directly to the project cost.

Step 4: Receive Incentives

Some savings are immediate.

Others are processed after documentation is submitted.

What Rebates Does Energize CT Offer?

Energize CT focuses on upgrades that permanently reduce energy use. If an improvement measurably lowers heating, cooling, or electrical demand, it likely qualifies for incentives.

At a high level, rebates typically fall into these categories:

Insulation & Air Sealing

Often the most impactful upgrades, including:

  • Attic insulation
  • Wall insulation
  • Basement and crawl space insulation
  • Rim joist insulation
  • Air sealing and duct sealing

These improvements reduce heat loss and stabilize your home’s performance.

Heating & Cooling Systems

Incentives may apply to:

  • Heat pumps (ducted and ductless)
  • High-efficiency furnaces and boilers
  • Heat pump water heaters

Rebates vary based on efficiency ratings and system type.

Income-Eligible Programs

Homeowners who meet income guidelines may qualify for enhanced incentives and significantly reduced out-of-pocket costs.

The smartest approach is to start with a home energy assessment, identify where your home is losing energy, and then apply available rebates strategically.

A Smarter Way to Think About Energy Upgrades

Most homeowners instinctively upgrade their heating or cooling equipment first. On the surface, that makes sense — if the furnace is old, replace it. If the AC struggles, upgrade it.

But that approach is often backwards.

Your home operates as a system. The building envelope — your attic, walls, basement, and air sealing — determines how much conditioned air stays inside versus how much escapes. If that shell is weak, even the most efficient HVAC system will work harder than it should.

When you strengthen the envelope first by improving insulation and air sealing, you reduce the workload on your equipment. That leads to shorter run times, more stable indoor temperatures, and better long-term efficiency.

Insulation, when properly installed, can last for decades. Mechanical systems eventually wear out and need replacement. That’s why a performance-first strategy makes sense — and it’s the philosophy Energize CT is built around.

How to Apply for Energize CT (The Right Way)

Applying for Energize CT rebates doesn’t have to be confusing — but it does need structure. Follow this sequence to make sure you don’t miss incentives or delay your rebates:

  1. Schedule a Home Energy Solutions Assessment
    1. This is your official entry point into the Energize CT program. A certified technician will evaluate your home’s energy performance, run diagnostics, and provide recommendations. To schedule your assessment, call 1-877-WISE-USE (877-947-3873) — the statewide energy information line where energy professionals can help you explore and apply for available services and assessments.
  2. Review Eligibility and Scope
    1. After your assessment, review the recommended upgrades and confirm which rebates apply to your project. Your contractor can help clarify what qualifies and what doesn’t.
  3. Confirm Rebate Structure
    1. Rebates vary by upgrade type and efficiency level. For insulation projects, documented rebates can be up to $2.00 per square foot when completed through an approved contractor — and even income-eligible customers can qualify for enhanced coverage.
  4. Complete Upgrades Through an Approved Contractor
    1. Work must be completed by an approved contractor to qualify for most rebates. These contractors know program standards and documentation requirements.
  5. Ensure Documentation Is Submitted
    1. Most contractors will submit rebate paperwork on your behalf. If you manage your own submission, rebates are typically processed through the Energize CT Online Rebate Portal or via Resource Innovations — the rebate processor. For questions about rebate status or submission issues, you can call 888-855-0282 or email CTRebates@Resource-Innovations.com.

Important: Do not complete major upgrades before confirming eligibility and rebate structure. Rebates depend on following the program’s procedures, including the initial assessment and documentation requirements.

By following this sequence and using the right contacts, you’ll maximize your rebate potential and streamline the process from assessment to incentive.

FAQ's about Energize CT

How much will I need to pay upfront for an insulation project using Energize CT?

Upfront insulation costs with Energize CT equal total project cost minus applicable rebates. Project cost depends on insulated area size, existing insulation levels, and rebate eligibility. For example, a $6,000 attic project with a $2,000 rebate requires a $4,000 upfront payment. Always confirm total cost, rebate amount, and final out-of-pocket cost before signing.

How long does an insulation upgrade typically take?

An insulation upgrade typically takes 1 to 2 days. Attic insulation upgrades usually finish in 1 day. Dense-pack wall insulation for an average 2,000-square-foot home typically takes 1 day. Basement or crawl space insulation requires 1 to 2 days depending on project scope. Crews complete most projects without requiring homeowners to leave.

Will adding insulation make my home too tight?

Adding insulation does not make a home too tight when installed correctly. The goal is to control uncontrolled air leakage, not eliminate ventilation. Air sealing reduces drafts and uneven temperatures by sealing attic penetrations, rim joists, and wall gaps. If post-upgrade testing shows reduced air exchange below recommended levels, mechanical ventilation systems maintain healthy airflow. A properly sealed home improves comfort and indoor air quality.

How soon will I notice a difference after upgrading insulation?

You will notice insulation upgrade benefits immediately. Homeowners report fewer drafts within 1 to 3 days, more even temperatures between floors, reduced furnace or heat pump run times, and quieter indoor spaces. Energy bill reductions typically appear during the first full heating or cooling season after installation. The primary change is improved indoor temperature stability.

What happens if rebate amounts change after I schedule my project?

Rebate amounts can change annually based on state funding and program updates. Once a project is documented and approved under current guidelines, the rebate amount is typically locked in for that scope of work if installation is completed within the required timeframe. Confirm eligibility and incentive structure before starting. Incentive programs more often decrease than increase over time.
