Record when cooling changes
Tell us whether air is warm at every vent, whether airflow is weak, and if cooling changes between idle and driving. Note outside conditions when it occurs, any clicking, unusual odor or recent A/C repair. Low airflow may involve a filter, blower or door actuator; warm air may involve a different part of the system.
Do not assume refrigerant is low or add a sealant product before evaluation. Refrigerant is not normally consumed like fuel, so a low charge may reflect a leak or earlier service. The symptom pattern helps determine whether the initial visit should focus on controls, airflow, fans or the refrigerant circuit.
Match the test to the refrigerant system
Vehicle refrigerant type, compressor design and service access vary by year and model. Appropriate checks may include vent temperature, accessible component inspection, fan operation, control signals and pressure testing. Some leak searches, recovery and component work need specialized equipment or a controlled space that is not available at every location.
Send the VIN or full vehicle details, plus any prior A/C invoice. We explain what the initial test can establish and whether additional equipment or a shop is needed. The $149 diagnostic/service visit includes the mobile visit and up to the first hour of initial testing; refrigerant, parts and further labor are separate and require approval.
Confirm the Calabasas work location
A driveway, gated community and commercial garage each have different entry and ventilation rules. Give the exact address or cross street, gate contact, garage clearance and whether the car can remain parked with hood access. If the vehicle is near Calabasas Road or the 101, provide an authorized off-street work area rather than a roadside location.
Share the year, make, model and whether the cooling failure is steady or intermittent. If engine temperature is also rising, mention it immediately because continued operation may be unsafe. Hye Tech confirms the mobile scope and site suitability before dispatch; not every refrigerant or compressor repair can be completed curbside.
Questions about this appointment
Does warm air prove the system needs refrigerant?
No. Airflow, fan, controls, leaks and compressor operation can also affect cooling.
Can refrigerant be added without leak testing?
A low charge should be assessed; topping off without finding the cause may offer only temporary cooling.
