Frequently Asked Questions

Find answers to common questions about torque specifications

Q1

What is the refrigerant type and capacity for the 1994-2001 Acura Integra HVAC system?

The 1994-2001 Acura Integra HVAC system uses R-134a refrigerant. The total system capacity is approximately 21.2 ounces (600 grams). Always refer to the under-hood label for exact specifications.

Q2

How do I diagnose a weak airflow from the HVAC system?

Weak airflow can be caused by a clogged cabin air filter, a malfunctioning blower motor, or obstructed air ducts. The cabin air filter should be inspected and replaced every 15,000-30,000 miles. The blower motor resistor or control module may also require testing and replacement if necessary.

Q3

What is the recommended procedure for recharging the AC system?

To recharge the AC system, first evacuate the system using a vacuum pump to remove moisture and air. Then, recharge with the specified amount of R-134a refrigerant (21.2 ounces). Use a manifold gauge set to monitor pressure levels, ensuring high-side pressure is between 200-250 psi and low-side pressure is between 25-45 psi at 80°F ambient temperature.

Q4

How do I troubleshoot a non-functional AC compressor?

A non-functional AC compressor can result from a blown fuse, faulty relay, low refrigerant levels, or a defective compressor clutch. Check the AC fuse (usually 10A) in the under-hood fuse box and the relay. Use a multimeter to test the clutch coil for continuity (typically 3-5 ohms). If refrigerant levels are low, inspect for leaks before recharging.

Q5

What are the common causes of HVAC system odors?

HVAC odors are often caused by mold or bacteria growth in the evaporator core or air ducts. Cleaning the evaporator core with an approved HVAC cleaner and replacing the cabin air filter can resolve this issue. Using an anti-bacterial treatment spray is also recommended.
