Energize CT Residential Energy Optimization | Effective September 1, 2026

Connecticut Raised the Heat Pump Rebate to $10,000

As of September 1, 2026, Energize CT pays $1,500 per ton, up to $10,000 per home, when a new cold-climate heat pump replaces the oil, propane, natural gas or electric resistance heat you have now. The old system has to come out or be permanently shut off. The rebate runs through December 31, 2026.

A Question Worth Sitting With

How Many More Winters Are You Willing to Hand Over to Your Current System?

Most Connecticut homeowners do not replace their heating equipment until something breaks. By then, they are making a $12,000 decision in a panic, in February, with a frozen house and whatever installer can get there fastest.

That is not a decision. That is a rescue.

Right now Connecticut is paying up to $10,000 toward that replacement, which gives you the ability to plan it, compare properly, and do it on your terms instead of on a broken furnace's terms.

A Few Honest Questions

1When was the last time your heating costs actually went down year over year?
2How old is your current furnace, boiler, or AC unit? Do you know its efficiency rating?
3If your system failed this January, what is your backup plan?
4Have you ever compared what you are paying for oil, propane, or natural gas to what a modern cold-climate heat pump would cost to run?
5What would an extra $100 to $300 a month in your household budget actually change?

If any of those questions gave you pause, the rest of this page is worth five minutes of your time.

What Connecticut Pays

The Rebate Depends on What You Are Replacing

Energize CT's Residential Energy Optimization incentive pays at two very different rates. Which one applies to your house comes down to the heating system you have today.

Replacing oil, propane, natural gas or electric baseboard heat

$1,500 per ton

Up to $10,000

Replacing an existing heat pump, or cooling only

$250 per ton

Up to $2,500

$10,000 is a lifetime cap per home, across all heat pump rebates combined.

A typical Central Connecticut home is three to four tons, so you can do the arithmetic yourself before anyone comes to the door.

Full displacement means the existing heating system is removed or permanently disconnected. Partial displacement is a separate path and requires a qualified integrated control from the approved products list.
You must be a residential electric customer of Eversource or United Illuminating.
Equipment must be on the Energize CT Heat Pump Qualified Product List.
Installation must be performed by a contractor in the Energize CT Heat Pump Installer Network.
Post-installation inspections are random and mandatory. Failing to complete one forfeits the rebate.

What Qualifies

Five Categories of Equipment Qualify for the Rebate

Qualifying equipment must appear on the Energize CT Heat Pump Qualified Product List, and that list is narrower than most homeowners expect. The same qualifying equipment is also what unlocks the Smart-E rate for the balance.

Air Source Heat Pumps

The most common whole-home solution. Replaces your furnace and AC with a single system that heats and cools efficiently down to subzero temperatures.

Ductless and Ducted Mini Splits

Ideal for additions, finished basements, older homes without ductwork, or zone-specific comfort upgrades.

Ground Source and Geothermal Heat Pumps

The highest-efficiency option available. Higher upfront cost, but unmatched long-term performance and lifespan.

Heat Pump Water Heaters

Two to three times more efficient than conventional electric or gas water heaters. Pairs well with a larger electrification project.

Air-to-Water and Optimization Systems

For homes using hydronic heat or combining heat pumps with existing hydronic loops. Less common, but covered.

Who Qualifies

Three Quick Checks Before You Call

We believe in saving you time. If you can answer yes to these three, you are almost certainly a fit.

You Are an Eversource or Avangrid Electricity Customer

This is the first hard requirement. If you pay an electric bill to one of these two utilities, you are in.

You Own Your Home in Connecticut

The program is for residential owner-occupied properties. Multifamily and commercial projects use different CT Green Bank programs.

You Are Open to Heat Pump Technology

The Energize CT rebate applies to qualifying heat pump equipment on the Energize CT Qualified Product List, and CellSun handles the rebate reservation paperwork for you as part of our process. The same qualification is what makes the Smart-E rate available if you want to finance the remainder.

Not sure if you qualify? Call (203) 427-7489 or request a free consultation. Cameron will tell you honestly, even if it means pointing you somewhere else.

The Cost of Waiting

What Happens If You Do Nothing?

Every month you keep an aging furnace, boiler, or AC running, you are paying a premium in fuel and electricity that you never get back.

Emergency replacements also cost more. Equipment availability shrinks in peak season, and rushed installs rarely get sizing and commissioning right.

The rebate is a meaningful amount of money, but the real value is replacing your system on your terms - not in a February emergency. Cameron has been in this industry for nearly 20 years and has watched Connecticut homeowners replace systems in a panic every winter. Planning ahead is always cheaper than reacting.

Paying the Balance

How Homeowners Cover What Is Left After the Rebate

The rebate handles a large share of the project. For the remainder, most homeowners use the CT Green Bank Smart-E Loan. Here are the full terms, without marketing spin.

Promo Rate

1.99%APR

5-Year Loan

Up to Up to $25,000

Best for: Homeowners replacing a single qualifying heat pump system who want the lowest rate and can handle a slightly higher monthly payment.

A $20,000 loan at 1.99% APR over 5 years is approximately $350 per month.

Blended Rate

BlendedAPR

5-Year Loan

Up to $25,001 - $50,000

Best for: Homeowners financing a larger heat pump project or combining heat pumps with other eligible energy improvements. The blended rate still beats most home improvement loans.

Program Details

1.99% APR promotional rate applies to 5-year Smart-E loans up to $25,000 for qualifying heat pump projects, available August 1 - December 31, 2026.
No money down.
No prepayment penalties at any point during the loan term.
A blended rate applies to loans over $25,000 (maximum $50,000) or loans including non-heat pump measures.
Rates and terms are set by CT Green Bank and participating Smart-E lenders, not by CellSun. We simply help you use the program correctly.

Why Work With CellSun

You Do Not Need a Salesperson. You Need a Guide.

The Smart-E program has rules. EnergizeCT rebates have paperwork. Heat pump sizing is the single most common thing installers get wrong. This is where a local, owner-led contractor matters.

Approved Smart-E Contractor in Good Standing

Not every HVAC installer in Connecticut can offer Smart-E financing. We can, and we have done the paperwork, certifications, and utility coordination to stay in good standing with the program.

Member of the EnergizeCT Heat Pump Installer Network

The 1.99% promotional rate requires an HPIN-qualified installer and an approved EnergizeCT heat pump rebate. It is a short list. We are on it.

Proper Sizing, Not Oversizing

The biggest reason homeowners hate their heat pumps is that the installer sized it wrong. We use manufacturer load calculations, not rules of thumb. A correctly sized system is the difference between loving it and resenting it.

You Talk to the Owner

Cameron Lovelace answers his own phone. He visits your home. He manages every project. When you have a question in year three, you call the same number and get the same person.

The Four-Step Plan

How This Actually Works

From the first phone call to a heat pump running in your home, here is the sequence.

Free In-Home Assessment

Cameron comes to your house, evaluates your current system, takes measurements, and explains your realistic options. No pressure, no hard sell, no fake timers.

Honest Proposal and Rebate Reservation

You receive a clear proposal with equipment, installation cost, expected EnergizeCT rebate, and your estimated monthly Smart-E payment - including the 1.99% APR / 5-year option if your project qualifies. We reserve your rebate with the utility.

Smart-E Loan Application

You apply directly with one of the participating Smart-E lenders. Approvals typically come back within a few business days. We help you every step.

Install, Commission, and Stand Behind the Work

CellSun designs the system, runs the load calculation, pulls the permits and performs the electrical work. A licensed HVAC installation partner performs the physical installation, using technicians who hold the Connecticut trade license the work requires. CellSun commissions the system to manufacturer spec with MeasureQuick, walks you through operation, and remains your point of contact for warranty, service and maintenance. Cameron manages the project from assessment through final commissioning, and he is who you call afterward.

Questions We Actually Get

Straight Answers to the Questions Homeowners Keep Asking

Every house is different, so CellSun runs a load calculation on your actual home before quoting rather than publishing a number it would have to walk back. What we can tell you up front is what Connecticut contributes: $1,500 per ton, up to $10,000, when the heat pump displaces oil, propane, natural gas or electric resistance heat, $250 per ton up to $2,500 when it replaces an existing heat pump or is cooling only, and Smart-E financing at 1.99% APR on a five-year term for the balance. Your quote is written and itemized.

1.99% APR is the real promotional rate on 5-year Smart-E loans up to $25,000 for qualifying heat pump projects, available August 1 through December 31, 2026. The rate is subsidized by CT Green Bank, which is why it is so low. There is no catch. There is, however, a qualification process: you must be an Eversource or Avangrid customer, your equipment must qualify for an EnergizeCT rebate, and you must work with a Smart-E approved contractor in the Heat Pump Installer Network. A blended rate applies to loans over $25,000 (maximum $50,000) or projects that include non-heat pump measures.

It depends on your project size and monthly budget. The 5-year term at 1.99% APR saves the most total interest and is ideal for single-system projects up to $25,000. If your project exceeds $25,000 or includes other eligible energy improvements, a blended rate applies. We walk you through the numbers before you apply.

Yes, and the honest answer names the equipment rather than one site-wide number. Rated low-temperature performance differs by line: the Mitsubishi Hyper-Heating systems we specify are rated to negative 13 degrees Fahrenheit, and the Gree line we quote is rated to negative 22. Connecticut's winter design temperature sits near 7 degrees, which is the number a residential design is actually built against, so the question that decides whether you like your heat pump is whether it was sized against a load calculation for your house, not the headline rating.

No. Smart-E loans have no prepayment penalties, at any point, for any reason. If you refinance your house or sell it or simply want to pay it off in year three, you can.

CT Green Bank allows loans above the $25,000 promotional cap up to $50,000 at a blended rate, which is still typically well below standard home improvement loan rates. We walk you through the math on your specific project.

Smart-E loans can cover additional eligible energy improvements (insulation, water heaters, solar, and more), but the 1.99% promotional rate only applies to the qualifying heat pump portion up to $25,000. Other improvements receive a blended rate. For most homeowners, it still comes out far ahead of a typical home equity loan.

Next Step

A 15-Minute Phone Call Will Tell You Everything You Need to Know

There is no obligation, no hard sell, and no pressure. If we are not the right fit, Cameron will tell you so. If you are not ready, he will tell you that too. What you will not get is a call center, a scripted pitch, or a follow-up pattern designed to wear you down. That is not how we work.

Call (203) 427-7489

The Energize CT rebate - $1,500 per ton, up to $10,000 - runs through December 31, 2026, and the Smart-E rate for the balance ends the same day. Starting early gives you time to reserve your rebate, complete the loan application, and schedule installation before peak heating season.
