Energy Smart Homes Demystified

How to Apply for the Energy Smart Homes Rebate in California: A Homeowner’s Guide

Learn how California homeowners can apply for the Energy Smart Homes rebate, maximize incentives for full electrification, and why systems like Harvest qualify for advanced technology bonuses through 2027.

Electrifying your home — swapping out gas appliances and systems for efficient electric alternatives like heat pumps — isn’t just good for comfort and the climate, it opens the door to significant rebates in California. The Energy Smart Homes Program is one of the state’s most valuable incentives for electrification projects, especially for single-family homes. This guide breaks down how to apply, what to expect, and how to qualify for the biggest possible rebates.

So you’ve been thinking about electrifying your home. Maybe it’s rising utility bills, maybe it’s to help support your climate goals, or maybe your water heater or furnace is nearing the end of its life. Whatever sparked the interest, one thing becomes clear pretty quickly: electrification can come with meaningful rebates and incentives, but figuring out how to actually access them can be daunting, time-consuming, and chocked full of fine print.

That’s especially true in California, where programs like Energy Smart Homes (ESH) offer some of the strongest rebates in the country for homeowners who fully electrify - yet many people leave money on the table simply because the process isn’t well explained. This guide is here to demystify that for you. We’ll walk through how the Energy Smart Homes program works, what steps homeowners should expect, how timelines typically play out, and how to structure your upgrades to qualify for the maximum incentives available so you can electrify with confidence, clarity, and the best possible return on your investment.

What Is the Energy Smart Homes Program?

The Energy Smart Homes Program supports California’s transition to all-electric homes by offering financial incentives for electrification projects, including HVAC, water heating, cooking, and clothes drying systems. It applies to:

• Single Family Residences, including homes, duplexes, townhomes, and ADUs
  
  
• Multifamily low-rise buildings
  
  

The program incentivizes alteration projects that replace gas appliances and systems with electric equivalents as well as new all-electric construction projects that meet state standards and codes. 

ESH is funded by utility customers and administered in PG&E®, SCE®, and SDG&E® territories to help reduce emissions and utility costs while increasing home comfort and energy resilience. 

How the Application Process Works (Step-by-Step)

1. Understand if You are Eligible 

ESH is funded by investor-owned utility ratepayers and administered in PG&E®, SCE®, and SDG&E® territories to help reduce emissions and utility costs while increasing home comfort and energy resilience. You must to be an electric customer of one of these utilities in order to be eligible for the program. 

This covers a majority of Californian households, but unfortunately parts of Northern and Eastern California are serviced by utilities that aren’t part of ESH. Similarly, municipal utilities (cities that have their own utility) would not qualify, though those often have their own strong incentives for electrification.

2. Determine Which Upgrades You Need to Qualify

To qualify for rebates under the Whole Building Electrification Alterations portion of the program, you must swap all gas appliances and equipment to efficient, all-electric alternatives. At least two of the following upgrades are needed to qualify:

• Heat pump space heating
  
  
• Heat pump water heating
  
  
• Induction cooking ( projects with existing electric cooking qualify without upgrade to induction)
  
  
• Electric clothes dryer
  
  
• Electrical infrastructure upgrades (optional, bonus incentives available) 

In short, you’ll need to fully electrify your home and ultimately cap the natural gas line from your utility. though there are different ways of doing that to increase your incentives.

2. Work With a Licensed Contractor

All work must be completed by a licensed contractor. This ensures your project meets eligibility requirements and that the rebate administrator can verify installation and compliance with program rules.

Important tips:

• Confirm your contractor understands all program requirements
• Take photos of your old equipment prior to removal, as this is necessary for the application (to confirm what you upgraded from)
• Keep detailed invoices and documentation of installed equipment and scope of work

3. Prepare & Submit Your Application

The ESH program is funded through at least 2027, so you have a bit of time to plan ahead for your electrification projects. However, the incentive levels remain available on a first-come, first-served basis until funds run out, so it’s still best to act quickly once your project is completed. Cool Davis

The rebate application is completed online through the Energy Smart Homes website; for additional support or questions, you can contact the program administrator at caenergysmarthomes@trccompanies.com. 

4. Complete Installation and Submit Final Documentation

Once installation is finished:

• Submit your final paid invoice, verification documents, and associated project photos
  
  
• Energy Smart Homes will review and disburse the rebate
  
  
• If you added infrastructure upgrades or advanced technology measures, be sure to include related documentation too
  
  

Understanding the Available Rebates

Base Incentives for Homeowners

For single-family homes under the Whole Building Electrification Alterations track:

• Base rebate: $4,250
  
  
• Heat pump clothes dryer bonus: $250
  
  
• Electric infrastructure upgrade bonus: up to $1,000
  
  

This means even a basic electrification project replacing gas furnace + water heater + dryer + cooking equipment can earn over $5,000 in incentives.

Advanced Technology Bonuses — Where Harvest Shines

The Energy Smart Homes program offers Advanced Technology Bonuses to encourage cutting-edge, high-performance electrification measures. These bonuses can dramatically boost your total rebate:

Examples of advanced technology bonus incentives (single-family):

• Thermal Energy Storage: $1,500
  
  
• Variable Capacity Heat Pump: $300
  
  
• Heat Pump without Electric Resistance: $300
  
  
• Integrated Heat Pump Space and Water Heating: $1,000
  
  
• Low Global Warming Potential (GWP) Heat Pump: $800
  
  
• Electrical Load Management: $3,500
  
  
• Induction Cooking with Integrated Battery: $3,000
  
  

These bonuses stack on top of the base rebates — and that’s where a fully electrified home with Harvest unlocks one of the best incentive stacks available.

How Harvest Captures the Strongest Incentives

Harvest’s system is uniquely positioned to qualify for some of the largest available incentives:

• Thermal Energy Storage: $1,500
  
  
• Variable Capacity Heat Pump: $300
  
  
• Heat Pump without Electric Resistance: $300
  
  
• Integrated Heat Pump Space and Water Heating: $1,000
  
  
• Low Global Warming Potential (GWP) Heat Pump: $800
• Plus the base rebate and electrical infrastructure bonus
  
  

In total, a fully electrified home that includes a Harvest can capture up to $9,150 in Energy Smart Homes rebates — far above what most conventional heat pump installations receive under this program. This is due to the deep alignment between Harvest’s architecture and the program’s advanced bonus categories. ESH can stack with other state and local incentives  to reduce costs further, making Harvest one of the strongest rebate-eligible solutions available.

A Note on New Construction

The Energy Smart Homes program isn't just for existing homes - it also supports all-electric new construction across single family, duplex, townhome, multifamily low-rise, and ADU project types. To be eligible, new construction projects must be all-electric and meet all applicable federal, state, and local laws and codes.

Base incentives for new construction are de-escalating by year of completion: in 2026, single family homes, duplexes, and townhomes receive $3,000 per unit, while multifamily and ADU units receive $1,600 per unit. In 2027, those drop to $2,500 and $1,400 per unit respectively. The deadline to submit completed documentation for 2026 incentive levels is November 16, 2026 - after that date, projects fall to 2027 levels.

New construction projects must also meet a set of program prerequisites to qualify, including heat pump space and water heating, induction cooking, communicating thermostats, and segregated electrical circuits. Single family homes additionally require EV charging infrastructure and battery storage readiness.

On top of the base incentives, new construction projects are eligible for the same Advanced Technology Bonuses available to alteration projects - including thermal energy storage ($1,500), integrated heat pump space and water heating ($1,000), and electrical load management ($1,500) - making a Harvest-equipped new build an especially strong candidate for stacking incentives. Builders and developers can enroll projects directly through the Energy Smart Homes website.

A Note on Multifamily and ADU Projects

While this article focuses on the retrofit of single-family homes, the Energy Smart Homes program also supports multifamily low-rise and ADU projects. These have a smaller  base incentive per unit, but are able to leverage the same  advanced technology bonuses.More information is available here: California Energy Smart Homes

Key Takeaways and Tips for Getting the Most from ESH

• Go all-in on electrification. Projects that convert all gas appliances (space heat, water heat, cooking, dryer) to electric earn the full suite of base incentives and advanced bonuses. Full electrification is required for the base rebate - but using advanced tech like Harvest gets you significantly more back, while reducing emissions further.
• Include advanced systems. Systems that combine space and water heating (like Harvest) and include thermal storage or other advanced technologies maximize bonuses and align with emerging building codes and future rebate opportunities. A fully electrified Harvest home can capture up to $9,150 in ESH rebates alone.
• Apply early - funds are first-come, first-served. Submit your application promptly once your project is completed, and work with a licensed contractor to meet eligibility requirements and documentation deadlines.‍
• Stack your incentives. ESH can be combined with other state and local programs, making electrification more affordable than ever. The incentive landscape changes rapidly, so check eligibility for additional programs with your contractor.
