What is the value of this QIV service to consumers?

Quality Installation Verification (QIV) testing ensures that your AC system is properly charged and has sufficient airflow. Using a COOL SMART Participating Contractor provides this benefit, which is not always performed by other HVAC technicians. The QIV service also helps the air conditioner operate more efficiently, meaning it's less expensive to operate and should last longer with fewer repairs.

In a recent New England study, air conditioning systems were tested for refrigerant level. Of the units tested, 31% were under-charged, while 28% were over-charged. This means only 41% - less than half - of all the units tested were properly charged. These results are consistent with other industry research in studies throughout the U.S.

What steps are involved in the QIV process?

There are four basic steps. The report and instruments used will vary slightly depending on which type of verification tool the contractor uses.

  • Contractor phones in, or enters on a small computer, the test data about your air conditioning system.
  • Data analysis on-site or via phone generates results of refrigerant charge and airflow test data.
  • If tests show manufacturer's equipment specifications for charge and airflow are not met, the system provides feedback with suggested modifications; technician completes work*, retests unit and resubmits results.
  • Homeowner receives a report with information explaining test results.

*In many cases, obtaining correct airflow may require additional work, such as duct sealing or changes to the duct system, for which there may be additional costs. Even if there are extra costs, they are well worth the investment in system performance, equipment reliability and long-term energy savings.
