HVAC Technicians Exam Newest 2026 Questions and
Correct Detailed Answers Already Graded A+
When is it acceptable to use a passive recovery device? - CORRECT ANSWER-It
is acceptable for a centrifugal air conditioner, a reciprocating liquid chiller, a large
commercial walk-in freezer with a single compressor, and a domestic refrigerator.
What must all appliances include for refrigerant handling? - CORRECT
ANSWER-All appliances must include a service aperture or process stub to add or
remove refrigerant.
What is typically used on small appliances for refrigerant access? - CORRECT
ANSWER-A straight tube accessed using a piercing access valve or a factory-
installed valve with machine threads and a 1/4 inch diameter.
What type of appliances can technicians charge after passing the Type I exam? -
CORRECT ANSWER-Technicians can charge motor vehicle air-conditioning
systems and appliances with 5 pounds or less of refrigerant that are hermetically
sealed and factory charged.
,What is the approximate pressure of a storage cylinder of recovered R-404A at
80°F? - CORRECT ANSWER-72 psig.
What is true about the sale of refrigerants like CFC, HCFC, HFC, and HFO? -
CORRECT ANSWER-It is restricted to technicians who are EPA-certified in
refrigerant recovery.
What must be done before starting a refrigerant recovery procedure? -
CORRECT ANSWER-It is necessary to disconnect the appliance from its power
source.
What should be done if refrigerant in a recovery cylinder is suspected to be
contaminated? - CORRECT ANSWER-Turn refrigerant in for reclamation.
Why must a technician check the oil for contamination after a compressor
burnout? - CORRECT ANSWER-Contaminants could damage recovery
equipment.
What must a technician do when using a self-contained recovery device on a
system with an operating compressor? - CORRECT ANSWER-Recover the
refrigerant to both 4 inches of mercury vacuum and 80% of the nameplate
charge.
, What is a recommended maintenance practice for recovery equipment? -
CORRECT ANSWER-Check recovery equipment for refrigerant leaks.
Why should the temperature of the cylinder stabilize to room temperature before
taking a pressure reading? - CORRECT ANSWER-Comparisons to a pressure-
temperature chart are only valid if both the pressure and temperature of the
refrigerant are stable and known.
How many access valves are needed to recover refrigerant from a sealed system
with a restricted capillary tube? - CORRECT ANSWER-Two valves: one on the
high side and one on the low side of the system.
Who must have access to a self-contained recovery machine? - CORRECT
ANSWER-Individuals performing maintenance, service, or repairs on appliances
containing CFC, HCFC, or HFC refrigerants.
What is true about the use of a standard vacuum pump for evacuation and
dehydration? - CORRECT ANSWER-It should never be used as a recovery
device in combination with a pressurized container.
What is the approximate pressure of a storage cylinder of recovered R-410A at
80°F? - CORRECT ANSWER-138 psig.
