2026 Tax Credits For Energy Efficient Home Improvement

As explained in a previous article, 2026 Home Heating Tax Credits, many of the HVAC energy tax credits under section 25C, the Energy Efficient Home Improvement Credit, and 25D, Residential Clean Energy Credit, of the 2022 Inflation Reduction Act expired as of December 31, 2025. In the article 2026 HVAC Tax Credits For Home Cooling Systems: the 30% tax credit under section 25C for upgrading cooling systems was capped at $600 per year of total project cost, contingent on the government-set efficiency tier.
What does that mean for NJ residents who want energy-efficient home improvements in 2026? It means that unless the home improvement project for energy efficiency was performed before December 31, 2025, and applied for on the taxes filed in 2026, there will no longer be a tax credit on federal taxes. Such projects as insulation, air sealing, new windows, doors, and new HVAC cooling or heating systems.

What Are The Best Cost-Effective Energy Efficient Home Improvements?
- A Professional Energy Audit: One of the best energy-efficient home improvement projects is that of a professional energy audit to assess the most cost-effective projects that reduce energy waste in your home, and then determine a plan of action.
- Adding a smart or programmable thermostat that best optimizes when the furnace or AC unit runs, based on when the home’s occupants are at home. With a smart thermostat, homeowners can save up to 10% on annual heating and cooling costs.
- Install Ceiling Fans: Since warm air rises, a ceiling fan can bring the warm air down into the room in winter or cool the warm air at the ceiling and prevent excessive running of the furnace or AC unit, saving dollars on the utility bills.
- Purchase ENERGY STAR appliances: ENERGY STAR certified home appliances can truly be a simple energy-efficient home improvement. Energy Star certified refrigerators, washer and dryers, dishwashers, and HVAC systems use less electricity or gas thanks to high-efficiency motors, sensors, and improved insulation. The purchase of ENERGY STAR products, thanks to their advanced technology, can cut monthly utility bills by 20 to 50 percent!
- Annual HVAC System Tune-ups: Save the cost of emergency repairs with preventative maintenance to the AC unit or heating system. Read our article: Why Springtime Is Best For AC Maintenance.
- Seal Air Ducts: A relatively simple project to improve a home’s energy efficiency is to seal the air leaks in HVAC ducts.
- Upgrading The HVAC Heating and Cooling Units: The $5,000 rule is a helpful guideline to help NJ homeowners decide whether to repair or replace their current HVAC heating and cooling system. Multiply the age of your unit by the cost of the needed repair, and if the number exceeds $5,000, replacing the HVAC system is a cost-effective, energy-efficient home improvement project. A modern, energy-efficient HVAC heating and cooling system will significantly reduce energy usage and utility bills, as well as improve home air quality.
- Use of a Whole House Dehumidifier or Humidifier: Taking the humidity from home, the home is not as warm, keeping the thermostat setting higher and the AC unit from running excessively. In winter, the thermostat can be set lower to prevent the furnace or boiler from running excessively.
- Add an HVAC Zoning System: With an HVAC zoning system, the NJ homeowner can control the temperature of each room of the house, so as not to heat or cool rooms not being used.

What Are The Available Financial Incentives For Energy Efficient Home Improvement?
In both the article 2026 Tax Credits For Cooling Systems, and 2026 Home Heating Energy Tax Credits we let it be known that even as federal tax credits would end as of January 1, 2026; New Jersey homeowners can still feel reassured by local support through programs like NJCEP and WARMAdvantage, which offer financial assistance for upgrades.
- The local utility firms of New Jersey offer a state rebate program known as NJCEP (NJ Clean Energy Program) which provides rebates up to $8,000 for heat pump installations, as well as other home energy improvement rebates.
- The WARMAdvantage or SAVEGREEN state programs provide NJ homeowners with the opportunity, through 2027, to purchase high-efficiency HVAC equipment.
- There are also HVAC contractors, such as PAWS, Perfect Air & Water Services, eager to work with New Jersey homeowners to provide the heating system that best suits their home and finances, offering a 10% discount on a new HVAC system.
- As simple as having a service agreement for routine maintenance of the HVAC cooling or heating system can save on energy costs!
- While 2026 federal tax credits for NJ residential clean energy home improvements to the HVAC heating or cooling system expired, there are state rebate programs, known as HEEHRA, for low to moderate-income NJ households.
The long-range objective of a more energy efficient home goes beyond a one-time federal tax credit to that of making your home more comfortable in the heat of summer and cold of winter, saving on repair bills and ensuring the SAFETY of family members, as well as improving the long-term value of one’s home investment should one wish to sell the home. Energy-efficient home improvements can be done with thoughtful planning. Now is the time to call a trained HVAC contractor about having a professional energy audit!
