Get a Free QuoteThe federal 25C heat pump credit is gone. But Connecticut's Energize CT program still offers $2,500 to $10,000 in rebates, plus 0.99% APR financing through the Smart-E Loan. NuWatt is HPIN-registered and handles every step — from Manual J design to rebate paperwork.
Section 25C expired December 31, 2025. The $2,000 federal heat pump credit that contractors quoted for years is now $0. Your installer choice determines whether you maximize the state incentives that are still available.
Section 25C — the $2,000 federal energy efficiency credit — expired December 31, 2025. If you install a heat pump in 2026, your federal credit is $0.
Any HVAC contractor still quoting you a $2,000 federal credit is either uninformed or hoping you won't notice until tax time.
Connecticut's Energize CT program is still fully funded for 2026. The Standard tier pays $250/ton (up to $2,500). The Energy Optimization tier pays $1,000/ton (up to $10,000).
Plus, the CT Green Bank Smart-E Loan offers 0.99% APR financing through June 30, 2026 — among the lowest rates available anywhere in the country.
We quote real 2026 numbers: $0 federal credit, full Energize CT rebate, and Smart-E financing options. No bait-and-switch. No expired credits in the estimate.
As an HPIN-registered contractor, we pre-register your project, install qualifying equipment, and submit the rebate paperwork — you don't chase anything.
Connecticut's Energize CT program pays substantial rebates for cold-climate heat pump installations. Which tier you qualify for depends on how much of your home heating you replace.
Maximum rebate: $2,500
Best for: Adding a mini-split to supplement your existing heating system, heating a bonus room or addition, or homeowners who want to keep their furnace as primary backup.
Maximum rebate: $10,000
Best for: Full oil-to-heat-pump conversion, whole-home comfort, maximum rebate. Eliminates fossil fuel dependence entirely. NuWatt provides the required Manual J load calculation as part of our design process.
The CT Green Bank's Smart-E Loan is one of the best clean-energy financing deals in the country. At 0.99% APR, a $15,000 heat pump financed over 15 years costs just $90 per month. That's less than most CT homeowners spend on oil deliveries.

We're not a generic HVAC company that dabbles in heat pumps. We're a New England energy company that's been installing heat pumps and solar since 2008 — and we know Energize CT inside and out.
The highest tier of Mitsubishi partnership. We have advanced training on Hyper-Heat systems, access to priority parts and support, and extended warranty options that standard HVAC companies cannot offer.
We are registered on the Energize CT Heat Pump Installer Network. We pre-register your project, verify equipment qualifies, and submit all rebate paperwork. You don't chase the rebate — we handle it.
Every project starts with a proper Manual J heating and cooling load calculation — not a rule-of-thumb estimate. This ensures your system is correctly sized for CT winters and qualifies for the higher Energy Optimization rebate tier.
Connecticut is Zone 5A with design temps of -1°F to -5°F. We select equipment rated for these conditions and design systems that maintain comfort without fossil fuel backup — unless you want it.
Our installation teams are trained professionals with specific heat pump expertise, held to NuWatt quality standards. Consistent training and accountability on every job.
We walk you through the CT Green Bank Smart-E application. Most HVAC companies don't know Smart-E exists or how to qualify — we include it in every eligible project.
Approximately 40% of Connecticut homes still heat with oil. At $3.50/gallon, the average home spends $2,700/year on heating oil. A cold-climate heat pump cuts that to roughly $1,200/year in electricity — and adds air conditioning.
From coastal Fairfield County to the Litchfield Hills, NuWatt designs heat pump systems for every CT climate condition and utility territory.

Not all heat pump installers are created equal — especially in a post-25C world where state rebate expertise matters more than ever.

Every system we install is on the Energize CT Qualified Product List and rated for ENERGY STAR Cold Climate (6.1) certification. We are brand-agnostic — we recommend the best equipment for your home, not whichever brand pays us the highest commission.

Best for: Lowest operating temperature, northern CT, Litchfield Hills
Best for: Strong cold-weather capacity retention, great value
Best for: Premium ducted systems, highest efficiency ratings

Best for: Reliable ducted option, strong warranty, quiet outdoor unit
Every home is different. Here are the most common heat pump installations we do across CT, with typical costs and Energize CT rebate amounts.
Replace your oil boiler with a cold-climate heat pump system. Eliminates oil deliveries and cuts heating costs by 40-60%. Qualifies for up to $10,000 Energize CT rebate through the Energy Optimization tier.
Add heating and cooling to a specific room, addition, or finished attic without ductwork. Single-zone mini-splits are the most cost-effective entry point for heat pump comfort.
Replace your central AC and furnace with a ducted cold-climate heat pump. Uses your existing ductwork for seamless whole-home heating and cooling from one system.
Pair a new heat pump with your existing oil or gas furnace as backup for extreme cold. The heat pump handles 80-90% of heating load while the furnace covers the coldest nights below -5°F.
Install 2-5 indoor units on a single outdoor unit to heat and cool multiple rooms independently. Ideal for colonial homes, split-levels, and homes with hot/cold spots.
Replace your electric or propane water heater with a heat pump water heater. Uses 60-70% less electricity. Separate Energize CT rebate available ($400-$750).
Everything Connecticut homeowners need to know about heat pump installation, Energize CT rebates, and working with NuWatt.
Yes. NuWatt Energy is registered on the Energize CT Heat Pump Installer Network (HPIN). This means we can pre-register your project, install qualifying cold-climate equipment, and process your Energize CT rebate of up to $10,000. We handle all paperwork including the pre-registration form, equipment qualification verification, and post-installation rebate submission.
No. The Section 25C energy efficiency tax credit expired on December 31, 2025. There is $0 federal credit available for heat pump purchases in 2026. Any contractor who quotes you a $2,000 federal credit is referencing an expired program. Connecticut state rebates through Energize CT are still active and can offset $2,500 to $10,000 of your installation cost.
Energize CT offers two rebate tiers. The Standard Air Source tier pays $250 per ton (up to $2,500) for replacing fossil fuel or electric resistance heating with a qualifying heat pump. The Energy Optimization tier pays $1,000 per ton (up to $10,000) for whole-home heating replacement where the heat pump becomes your primary heat source. Energy Optimization requires a whole-home heating design and eliminates or significantly reduces your fossil fuel dependence.
The Smart-E Loan is a financing program through the CT Green Bank offering 0.99% APR for energy improvements including heat pumps. You can borrow up to $50,000 with terms of 5 to 20 years. The program is available to Eversource and United Illuminating customers and runs through June 30, 2026. NuWatt helps you apply as part of our installation process — we handle the contractor verification and project documentation.
Yes. Connecticut is in IECC Climate Zone 5A with design temperatures of -1°F to -5°F. Modern cold-climate heat pumps like the Mitsubishi Hyper-Heat operate down to -13°F and the Fujitsu XLTH operates to -15°F — well below anything Connecticut experiences. These systems maintain 75-85% of their rated heating capacity at 5°F and still produce meaningful heat at -13°F. All equipment we install is on the Energize CT Qualified Product List and rated for ENERGY STAR Cold Climate (6.1) certification.
A single-zone ductless mini-split costs $3,800 to $7,500 installed. Multi-zone ductless systems run $8,500 to $19,000. Ducted whole-home heat pumps cost $12,000 to $23,000. Hybrid dual-fuel systems (heat pump plus existing furnace backup) cost $14,000 to $26,000. After Energize CT rebates ($2,500 to $10,000), your net cost drops significantly. A 0.99% Smart-E Loan can spread payments over 5-20 years.
The average Connecticut home heating with oil spends about $2,700 per year on fuel (770 gallons at $3.50/gallon). A cold-climate heat pump heating the same home costs approximately $1,200 per year in electricity at $0.27/kWh — a savings of roughly $1,500 per year. Over 15 years, that is $22,500 in savings, plus you eliminate oil tank maintenance, delivery fees, and the risk of oil spills. You also get air conditioning included at no additional operating cost.
NuWatt serves all 8 Connecticut counties: Hartford, New Haven, Fairfield, Litchfield, Middlesex, New London, Tolland, and Windham. We install in both Eversource and United Illuminating territories. Whether you are in downtown Hartford or rural Litchfield Hills, we design systems for your specific climate conditions and utility territory.
A single-zone ductless mini-split takes 1-2 days to install. Multi-zone ductless systems take 3-5 days. Ducted whole-home systems take 2-3 days if using existing ductwork. From initial consultation to completed installation, the typical timeline is 3-6 weeks including the Energize CT pre-registration process, equipment ordering, and scheduling. NuWatt handles all permitting and rebate paperwork.
It depends on your home, budget, and comfort goals. A full heat pump replacement qualifies for the higher $10,000 Energy Optimization rebate and eliminates fossil fuel costs entirely. A hybrid system pairs a heat pump with your existing oil or gas furnace — the heat pump handles 80-90% of heating, switching to the furnace only on the coldest nights. Hybrids qualify for the $2,500 Standard rebate. NuWatt provides a Manual J load calculation to recommend the right approach for your specific home.
