If you’re replacing your HVAC system, upgrading insulation, or planning weatherization work in Delaware, you may qualify for rebates that reduce your upfront costs. HVAC rebates are available through utility programs, but they often require complementary work such as air sealing and insulation to maximize energy savings. Accessing these programs correctly means understanding what qualifies, which contractors are approved, and how to avoid application mistakes.
This guide covers Delaware HVAC rebates and related energy efficiency programs available to homeowners in 2026, what upgrades qualify, how the application process works, and how to access these programs without delays or disqualification.
Delaware homeowners have access to several rebate programs depending on their utility provider, income level, and the type of energy efficiency work they’re planning.
Delmarva Power serves most of Delaware, including New Castle County, and offers rebates for qualifying energy efficiency upgrades. Their programs target residential customers who complete qualifying work through approved contractors.
Common rebates include:
Delmarva Power typically requires a home energy audit before approving rebates for HVAC or insulation work. This ensures that the upgrades address your home’s specific needs and meet program performance standards.
If you live near the Pennsylvania border or in areas served by PECO, you may qualify for their energy efficiency programs instead of or in addition to Delmarva Power rebates. PECO offers similar incentives for HVAC upgrades, insulation, and air sealing.
PECO’s programs also emphasize the home energy audit as the starting point. The audit identifies where your home loses energy and what improvements will deliver the greatest return—both in comfort and utility savings.
The Energy Coordinating Agency (ECA) administers Delaware’s Weatherization Assistance Program, funded through the Low Income Home Energy Assistance Program (LIHEAP). If you’re income-eligible, you may qualify for comprehensive weatherization services at no cost, including HVAC repairs or replacements when necessary for health and safety.
These programs cover:
Income thresholds are based on household size and are updated annually. ECA works with approved contractors like Energy Services Group to deliver these services to qualifying Delaware residents.
Not all energy improvements qualify for rebates. Programs focus on upgrades that deliver measurable energy savings and meet specific technical requirements.
To qualify for Delaware HVAC rebates, your new system typically must meet minimum efficiency ratings:
Installing a qualifying system alone isn’t enough; proper duct sealing is also required, along with correct refrigerant charge and airflow verification. This is why utility programs require approved contractors who document installation quality.
Rebate amounts for HVAC systems vary based on equipment type, efficiency tier, and whether you’re also completing complementary work like insulation or air sealing. Higher-efficiency systems typically qualify for larger rebates.
HVAC rebates often work best when combined with insulation and air sealing improvements. Many utility programs encourage or require these upgrades together because they comprehensively improve both the HVAC system and your home’s thermal envelope.
Insulation rebates apply to areas where adding insulation improves thermal performance:
Spray foam insulation qualifies when it meets R-value requirements and is installed by approved contractors. Because spray foam provides both insulation and air sealing, it often addresses multiple rebate categories in one upgrade.
A professional home energy audit is the foundation of most rebate programs. The audit includes:
The audit costs are often subsidized or covered entirely by utility programs. Energy Services Group, as a DOE-Certified Verifier, conducts comprehensive audits that meet Delmarva Power and PECO program requirements.
Rebate amounts vary by program, utility provider, and the scope of work completed. While specific dollar amounts change annually based on available program funding and approvals from the utility commission, here’s what you can generally expect:
HVAC system rebates:
Homeowners installing qualifying high-efficiency HVAC equipment typically receive several hundred dollars per system. Heat pumps and higher-tier efficiency equipment often qualify for larger rebates than standard systems. The exact amount depends on equipment specifications and whether you’re replacing central air conditioning, a furnace, or installing a heat pump.
Insulation and air sealing rebates:
These vary based on the area insulated, R-value improvement, and measurable air leakage reduction. Comprehensive insulation and air sealing projects—especially when paired with HVAC upgrades—can result in combined rebates of over a thousand dollars.
Duct sealing:
When performed as part of HVAC system replacement or as a standalone improvement, duct sealing qualifies for rebates based on measurable leakage reduction.
Home energy audits:
Many programs subsidize or fully cover the audit cost when you complete recommended improvements. In some cases, the audit is free upfront.
For current rebate amounts specific to your planned upgrades, check the Delmarva Power or PECO rebate websites, or contact Energy Services Group for up-to-date program information.
In most cases, you typically cannot combine utility rebates from multiple providers for the same upgrade. However, you can often stack utility rebates with federal tax credits for energy efficiency improvements.
For example, if you install a qualifying heat pump, you might receive:
Always verify current tax credit eligibility with a tax professional, as federal programs change.
The rebate application process varies by program, but most follow a similar structure. Missing steps or working with non-approved contractors is the most common reason rebates get delayed or denied.
Start with a professional energy audit. This serves multiple purposes:
Delmarva Power and PECO subsidize audit costs for program participants. Income-eligible residents receive free audits through ECA.
Most utility rebate programs require that work be completed by approved or participating contractors. Using a non-approved contractor can disqualify your rebate entirely, even if the work is done correctly.

Once the work is complete, your contractor submits required documentation:
For income-eligible weatherization, ECA manages the entire process—you don’t handle applications or documentation.
If utility bills consume a significant portion of your household income, you may qualify for comprehensive weatherization at no cost through Delaware’s income-eligible programs, including HVAC repairs or replacement when needed.
Eligibility is based on household income relative to federal poverty guidelines. Income thresholds are updated annually and vary by household size.
Priority is given to:
Contact the Energy Coordinating Agency directly to determine eligibility or ask Energy Services Group—we work with ECA and can guide you through the process.
Income-eligible weatherization is comprehensive:
All work is completed at no cost to qualifying households. There are no rebates to apply for—ECA manages the entire process.
HVAC rebate programs exist to improve energy efficiency across Delaware’s housing stock, but they also ensure work is done correctly. That’s why most programs require approved contractors.

Can I still receive HVAC rebates if I’m not income-eligible?
Yes. Delmarva Power and PECO offer standard energy efficiency rebates to all residential customers, regardless of income, for qualifying HVAC upgrades completed by approved contractors. Income-eligible weatherization programs are separate and have no cost to qualifying households.
Do I need to apply for the rebate before or after the work is done?
It depends on the program. Some utility rebates require pre-approval before work begins, while others allow post-completion applications within a specific timeframe (usually 60–90 days). Working with an approved contractor like Energy Services Group ensures you follow the correct process for your specific program.
Does my contractor have to be approved by the utility company?
For most rebate programs, yes. Using an approved or participating contractor is often a requirement for rebate eligibility. This ensures work meets program standards and documentation is handled correctly. Energy Services Group is approved for Delmarva Power and PECO programs.
How long does it take to receive my rebate?
Processing times vary by program but typically range from 4–8 weeks after your application is approved. Complete, accurate documentation speeds up processing. Missing information or application errors cause delays.
Can I combine a utility rebate with federal tax credits?
Yes. In most cases, utility rebates can be combined with federal energy efficiency tax credits. For example, you might receive a utility rebate for installing a heat pump and also claim the federal tax credit (up to 30% of cost, subject to annual limits). Consult your tax advisor for specifics on current federal programs.
