What Is the Columbia Gas WarmWise Rebate Program
Columbia Gas of Pennsylvania’s WarmWise program provides cash rebates for qualifying energy-efficiency improvements to existing residential customers. The program covers a range of improvements, including insulation and air sealing, furnaces, boilers, water heaters, and smart thermostats.
Rebates are issued as checks, not utility bill credits, and are typically processed in 4 to 6 weeks after a complete application is received. Rebate quantities are limited and approved on a first-come, first-served basis, so submitting applications promptly after project completion is important.
The program is funded through levels approved by Pennsylvania’s Public Utility Commission, and applications must be submitted within 120 days of purchase and installation or by December 31, 2028, whichever comes first.
WarmWise Rebate for Insulation and Air Sealing
Rebate Amount
25% of the total cost of qualifying contractor-installed insulation and air sealing, up to a maximum of $2,500.
Important Requirement — Both Must Be Included
To qualify for the insulation rebate, both insulation and air sealing must be included in the same project. An insulation-only project does not qualify. An air sealing-only project does not qualify. Both measures must be completed together.This is an important detail that some homeowners miss when planning projects. York Home Performance includes air sealing in every insulation project as part of our standard process, so our work naturally meets this requirement.
Blower Door Test Required
Columbia Gas requires that a qualified contractor perform a blower door test to determine the amount of air leakage in your home. This is a required component of the rebate application and is part of our standard diagnostic process.
*Note: Rebate amounts are subject to change and depend on available program funding. Verify current amounts with York Home Performance at the time of the estimate.*

Frequently Asked Questions About Columbia Gas WarmWise Rebates
How much is the Columbia Gas rebate for insulation?
The Columbia Gas WarmWise rebate covers 25% of the total cost of qualifying contractor-installed insulation and air sealing, up to $2,500. Both insulation and air sealing must be included in the same project to qualify.
Why do both insulation and air sealing need to be included?
Columbia Gas requires both insulation and air sealing as part of the qualifying project because air sealing is what makes insulation effective. Installing insulation without addressing air leaks significantly reduces its performance. York Home Performance includes air sealing in every insulation project as standard practice, so our work naturally meets this requirement.
How long does it take to receive the Columbia Gas rebate?
Columbia Gas issues rebates as checks, not utility bill credits. Processing typically takes 4 to 6 weeks after a complete application is received. Applications must be submitted within 120 days of installation or by December 31, 2028, whichever comes sooner.
Can I combine Columbia Gas and PPL Electric rebates on the same project?
Yes. If your home is served by both Columbia Gas for natural gas and PPL Electric for electricity, you may qualify for rebates from both programs on the same insulation and air sealing project. We check your eligibility for all applicable programs with every estimate.
What if I only have insulation done, no air sealing?
An insulation-only project does not qualify for the Columbia Gas WarmWise insulation rebate. Both insulation and air sealing must be included together. This is one reason we recommend including air sealing in every insulation project: it improves performance and qualifies you for the rebate.
Does my home have to be heated with natural gas to qualify?
Yes. The primary heat source must be natural gas through Columbia Gas. Customers who are switching from one fuel type to another are not eligible for this rebate.
