What would be the cost for an HHC membership for a customer with five systems?
50 dollars a month
Why are decay tests important?
To ensure that no moisture or leaks are present in the system
What does a hydronic system circulate?
Water
Why do gauges show PSIG instead of PSI?
PSIG stands for pounds per square inch gauge. Refrigerant gauges don't account for atmospheric pressure (14.7 psi)
When a system is not coming on, this component is the thing we check
The thermostat

What does the term "one ton of refrigeration" come from?
The amount of heat required to melt on ton (2,000 pounds) of ice over a 24-hour period
What will cause a high delta t?
Evaporator malfunction or low air flow
You measure the resistance of a single phase PSC compressor. C to R is 1.2 ohms, and C to S is 3.5 ohms. What must the resistance be between S and R if the windings are perfectly healthy?
4.7 ohms
What year was the HVAC department added to the company
2003
Why specifically does pulling a vacuum remove moisture?
Pulling a vacuum causes the boiling point of water to drop (The boiling point of water at 500 microns is -12 degrees)
Roughly, what is the torque specification for a 1/4 inch flared fitting for a universal pressure switch?
10-12 ft-lbs
What do CFC, HCFC, HFC, and HFO stand for?
Chlorofluorocarbon(r12), hydrochlorofluorocarbon(r22), hydrofluorocarbon(r410a & r32), and hydrofluoroolefin(r1234yf)
What is the DS/BK terminal for on a Honeywell Truzone panel?
This is if the HVAC equipment has a DS, BK, ODD, or DHUM terminal. When 2 or 3 zones are calling for cooling, this terminal will be energized, which will run the blower fan at the normal speed. When only 1 zone is calling for cooling the fan runs at a reduced speed which will require less air to be by-passed.
