HVAC contractors who issue ACCA Quality Installation (QI) certificates see real, operational benefits almost immediately. The process helps reduce costly callbacks (which can average between $500-1,500 a pop for many companies), creates consistent install standards across crews, and provides documented proof that systems are operating as designed at startup.
Just as important, it gives contractors objective data they can stand behind. They’re able to prove the quality of their work, justify the value of their services to homeowners, and create a clear differentiator between themselves and their competitors.
So, of course, the first question we’re usually asked is: what would my techs actually have to do to earn a QI certificate in the field?
ACCA’s QI process is powered by the measureQuick app. Below you’ll find more information about how QI certificates are earned and issued.
ACCA QI VEO Certificate requirements
To complete the Verified Equipment Operation (VEO) certificate workflow in measureQuick, techs will need to meet all of the below criteria:
- Followed manufacturer installation instructions
- System piping completed, nitrogen flowed at all times during brazing
- System passed 60 minute temperature compensated pressure test
- System evacuated below 500 microns, passed a decay test
- System charge opened into lineset
- Line wiring and control wiring complete, fuses in fuse block or disconnect, power is on
- Condensate trap primed
- System ready to be operated/commissioned
- Tight plenum connections
- Gas line purged/venting complete (furnaces only)
These steps should look familiar to any contractor focused on quality work. The difference is that the measureQuick workflow creates a documented record that those steps were completed, and confirms that the work was done correctly using actual performance data.
What tools are required to issue an ACCA QI Certificate?
To start, any install tech needs to be using measureQuick.
The ACCA Verified Equipment Operation (VEO) workflow in measureQuick then requires the use of Bluetooth-connected tools. These tools prevent manual data entry and eliminate the possibility of fabricated numbers. There’s no cheating, because the performance data is captured directly from the tools themselves.
For a typical install, the technician will need:
- Two manometers to measure static pressure
- Two psychrometers to measure temperature split
- Refrigerant pressure and temperature probes
- An outdoor air psychrometer
- A Bluetooth multimeter for electrical measurements
measureQuick guides the technician on where to place each probe and includes visual diagrams and tutorials. This helps ensure measurements are taken correctly.
ACCA’s step-by-step QI workflow process
- Open the guided VEO workflow in measureQuick.
- Verify the jobsite location and pull in customer info from your CRM.
- Use measureQuick’s AI system profiler, which quickly imports key system details from rating plates.
- Place Bluetooth probes and capture required measurements.
- Commission the system and review performance data, and resolve any diagnostics using the in-app guidance.
- Generate the QI certificate for the homeowner once all installation criteria have been met!
How long does it take to complete the ACCA QI workflow in measureQuick?
With practice, most contractors complete the full QI workflow in about 30 minutes at the end of the install. Even for teams new to the process, the time investment is typically under an hour.
ACCA’s QI process may add a little bit of upfront time to installs, but consider the time and money you’ll save!
Contractors who issue QI certificates can see their callback rates drop from 20% or even 30% to 2% or lower. One contractor in Virginia we’ve been working with has been losing $250,000 a year on install callbacks!
A repeatable process for quality HVAC installation
Issuing QI certificates creates consistency across install crews. Every technician follows the same commissioning process and verifies the same performance targets, reducing variation between installers and locations. When issues do arise, in-app diagnostics and remote streaming support help teams resolve problems faster without rolling another truck.
For owners and managers, this measured data replaces assumptions, making oversight easier without constant site visits. It also strengthens value conversations with homeowners, shifting discussions from claims to proof, especially as higher efficiency systems and heat pumps become more common.
