The US House of Representatives passed two bills with direct implications for HVAC efficiency standards and the rebate programmes that have been driving heat pump adoption for the past two years. For contractors who have been using federal rebates as a selling tool, and for homeowners who have been waiting to tap those programmes, the legislative developments of 2026 represent real and material risk.
The bills are not identical in their targets or their mechanisms, but their combined effect — if they advance through the Senate and reach the President's desk — would constrain the efficiency mandates and rebate structures that have shaped the residential HVAC market since the Inflation Reduction Act passed in 2022.
What the Two Bills Actually Do
The first bill targets minimum energy efficiency standards for residential HVAC equipment. It would roll back or freeze certain SEER2 minimum standards, with proponents arguing that higher mandated efficiency increases equipment costs for consumers and reduces access to affordable equipment, particularly in lower-income households.
The second bill addresses the High-Efficiency Electric Home Rebate Act programme — the HEEHRA component of the Inflation Reduction Act that funds state-administered rebates for heat pump installations. The bill would restructure funding mechanisms in ways that critics argue would reduce the rebates available to homeowners in the near term.
The US House passed legislation in 2026 targeting HVAC minimum efficiency standards and the High-Efficiency Electric Home Rebate Act programme, creating uncertainty around the rebate availability and efficiency mandates that have supported heat pump market growth.
HVAC Rebates Under Threat
The HEEHRA programme has been one of the most powerful selling tools available to HVAC contractors selling heat pumps and heat pump water heaters. Under the programme, qualified homeowners can receive point-of-sale rebates of up to $8,000 for heat pump installation — a figure that, combined with the 25C federal tax credit, can reduce the consumer net cost of a heat pump replacement to levels competitive with gas furnace alternatives.
State implementation of HEEHRA has been uneven, with some states launching programmes and others still in the process of establishing the administrative infrastructure to distribute funds. The House bill's restructuring of funding mechanisms creates uncertainty about whether states that have not yet launched programmes will have access to the full funding originally allocated.
For contractors in states with active HEEHRA programmes, the legislative developments represent both an urgency signal — homeowners who are considering heat pump upgrades should move before funding becomes less certain — and a risk that the rebate availability they have been marketing may change.
Efficiency Standards: What Could Change
The minimum efficiency standards question is more complex. SEER2 regional minimums took effect in 2023, and the industry has already invested heavily in product development and distribution to comply with the new standards. Rolling back or freezing those standards would create market confusion and potential inventory disruption for distributors and contractors who have transitioned their product lines.
ACCA and other industry organisations have raised concerns about the efficiency standards bill on these practical grounds, even where they might agree with the underlying policy argument about consumer affordability. The disruption cost of reversing standards that the market has already priced in is real and affects contractors directly.
How Contractors Should Position This With Customers
The legislative uncertainty creates a specific selling opportunity. Homeowners who have been considering heat pump upgrades and planning to use HEEHRA rebates have a reason to act sooner rather than later. The rebates exist now. Their future availability is uncertain. That is a factually accurate and legitimate basis for a conversation.
Contractors should:
• Check the current status of HEEHRA in your state. Some states have active programmes, others are pending. The status affects whether you can offer the rebate as a current selling tool.
• Be accurate about what is confirmed versus what is at risk. Do not promise rebate amounts that depend on legislation that has not been finalised.
• Stay connected to ACCA's advocacy updates. ACCA is tracking the Senate calendar and the White House position on these bills. The legislative picture could change significantly over the coming months.
Frequently Asked Questions
What HVAC bills passed the House in 2026?
The House passed two bills targeting HVAC markets: one addressing minimum energy efficiency standards under the SEER2 framework, and one restructuring funding mechanisms for the High-Efficiency Electric Home Rebate Act (HEEHRA) programme that funds state-administered heat pump rebates.
What is the HEEHRA HVAC rebate programme?
HEEHRA — the High-Efficiency Electric Home Rebate Act — is a component of the Inflation Reduction Act that provides funding for state-administered point-of-sale rebates on heat pumps and other high-efficiency electric appliances, with heat pump rebates of up to $8,000 for qualified households.
Are HVAC efficiency standards being rolled back in 2026?
The House passed legislation that would affect certain SEER2 minimum efficiency standards, but the bill has not been signed into law. The Senate and Presidential action remain uncertain. SEER2 standards remain in effect as of April 2026.
How do HVAC efficiency standard changes affect contractors?
Changes to efficiency standards create product line transition costs, inventory planning uncertainty, and customer communication challenges for contractors. Rolling back recently implemented standards would be particularly disruptive given the distribution investments made to comply with SEER2 requirements.
