CT Green Bank Smart-E Loan | Approved Contractor
From August 1 through December 31, 2026, Connecticut homeowners can finance a qualifying heat pump through the CT Green Bank Smart-E Loan at 1.99% APR on a 5-year term up to $25,000. Loans over $25,000 (up to $50,000) or projects with non-heat pump measures receive a blended rate. No money down. No prepayment penalties. Real answers from a local installer who answers his own phone.
A Question Worth Sitting With
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.
Smart-E financing gives you the ability to plan, compare, and replace on your terms - starting with 1.99% APR on a 5-year loan up to $25,000 for qualifying heat pump projects.
If any of those questions gave you pause, the rest of this page is worth five minutes of your time.

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.
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.

What You Can Finance
The Smart-E special rate applies only to heat pump equipment that also qualifies for an EnergizeCT rebate. That list is narrower than most homeowners realize, which is why working with a Smart-E approved contractor matters.
The most common whole-home solution. Replaces your furnace and AC with a single system that heats and cools efficiently down to subzero temperatures.
Ideal for additions, finished basements, older homes without ductwork, or zone-specific comfort upgrades.
The highest-efficiency option available. Higher upfront cost, but unmatched long-term performance and lifespan.
Two to three times more efficient than conventional electric or gas water heaters. Pairs well with a larger electrification project.
For homes using hydronic heat or combining heat pumps with existing hydronic loops. Less common, but covered.
Who Qualifies
We believe in saving you time. If you can answer yes to these three, you are almost certainly a fit.
This is the first hard requirement. If you pay an electric bill to one of these two utilities, you are in.
The program is for residential owner-occupied properties. Multifamily and commercial projects use different CT Green Bank programs.
Smart-E heat pump financing applies to eligible equipment that qualifies for an EnergizeCT rebate. We handle the rebate reservation paperwork for you as part of our process.
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
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 1.99% promotional rate is a meaningful savings opportunity for qualifying heat pump projects, 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.
Why Work With CellSun
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 installer matters.
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.
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.
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.
Cameron Lovelace answers his own phone. He visits your home. He oversees every install. When you have a question in year three, you call the same number and get the same person.
The Four-Step Plan
From the first phone call to a heat pump running in your home, here is the sequence.
Cameron comes to your house, evaluates your current system, takes measurements, and explains your realistic options. No pressure, no hard sell, no fake timers.
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.
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.
Our crew installs the system, commissions it to manufacturer spec, walks you through operation, and remains your point of contact for warranty, service, and maintenance for years to come.
Questions We Actually Get
Next Step
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.
Rebate reservations and loan approvals take time, and installation calendars fill up ahead of peak heating and cooling season. Starting early is always the smoother path.
