Existing Homes Program

It's true: some contractors are better than others.

ACCA Quality Assured Accreditation is your proof.

Existing Homes Program

QA Residential Service & Installation (RSI) is an accreditation program for contractors that want to prove to their customers in the residential replacement marketplace that they follow the acceptable guidelines for quality HVAC installation.

It’s true that not all contractors are created equal, and those contractors who perform truly quality work have long clamored for a way to prove that they are better than their competitors. To meet this need, the ACCA Board of Directors created the RSI accreditation.

Participating contractors agree to follow the recommended business practices in the QA Contractor Elements. These practices are necessary for an operation to provide quality service and replacement work.

Application Process

QA Contractor Accreditation is open to all contractors able to meet the requirements; ACCA membership is not required. (ACCA members receive a $200 discount on QA program fees.) 

Already an accredited New Homes Contractor? If so, complete the RSI orientation and earn that accreditation as well.

If you are new to the QA Program, the application is a multi-step process. Click here to learn more and apply.  Successful applicants can choose to participate in the New Homes program, the Existing Homes (RSI) program, or both. There is only one fee and one application process.

ESVI certification can be achieved on its own, but it is also included as part of almost every Verified System Performance (VSP) certificate through ACCA’s Quality Installation (QI) program. With a QI certificate, you can maximize the value of both the ENERGY STAR brand as well as the third-party, data-driven verification of Quality Installation.
