Indoor Air Quality
Why is airflow critical for UV effectiveness
What is :
All Contaminants must pass by the lamp to be treated
How Many CFM are required Per Ton when sizing residential duct systems?
What is :
400 CFM / Ton
A frozen coil is most commonly caused by these two issues.
What are :
low airflow or low refrigerant
"ACE" Stands for?
What is :
Awesome Customer Experience
What must be worn before entering every customer’s home?
What are :
shoe covers
Why do customers still smell odors after UV install sometimes
What is :
The source is still present or insufficient oxidation/contact time
This measurement determines how hard the blower is working against the duct system.
What is :
static pressure
Float switch keeps tripping after clearing drain. What’s the real problem
What is :
Double trap, Improper drain pitch or recurring Zooglea buildup
Presenting three options to the customer is commonly referred to as this.
What is:
Good / Better / Best?
All Technicians must contact this department before closing out their last call.
What is:
dispatch
Airborne particles can be as small as this measurement.
What is :
0.3 microns
Changing the amount of ductwork in a home will require these 2 things
What is :
30% or more, and add returns to existing bedrooms
Thermostat satisfied but house still feels humid
What is :
Poor Duct design & poor dehumidification or oversized system
This is the reason we run ACE calls, beyond just fixing equipment
What is :
To deliver a 5-star experience and create long-term customers (membership + future opportunities)
This must happen after every single call to ensure accuracy and set up the next job for success.
What is :
Debriefing with the office
Why can a “better or High MERV Pleated filter" actually make a system worse
What is :
Increased static pressure reducing airflow
A system with high static pressure and low airflow will typically result in this system condition
What is reduced capacity, Excess condensation, and potential coil freezing.
What’s the real reason airflow issues are commonly misdiagnosed as refrigerant problems
What are :
Similar symptoms such as (low capacity, poor cooling)
When a customer is highly engaged and asking questions, this is how the tech and HCA should operate.
What is :
Split up, with the HCA engaging the customer while the tech continues diagnostics
This is the biggest reason techs lose sales / opportunities
What is :
Failure to communicate value
A system has correct charge, clean coils, new IAQ upgrades, and still underperforms. Static pressure is high, humidity is elevated, and airflow is inconsistent.
What is :
poor duct design and airflow restriction affecting total system performance
Size the branch duct size for the following mixing box with (2) 8" , (3) 4" , (1) 5" and (1) 9" flex ducts @ .05" WC
What is :
14" Flex for 700 CFM
A system has correct refrigerant charge, new equipment, and still performs poorly. What is the true root cause?
What is :
Duct system restriction or improper design
This cultural element keeps ACE momentum strong throughout the day and reinforces wins.
What is :
GroupMe chat / real-time communication celebrating wins and updates
An HVAC job totaling over this dollar amount requires this
What is :
$15,000 & a NOC
