THE IMPORTANCE OF HVAC Performance Check
What is an HVAC performance check and how does it work?
An HVAC performance check is a service that a technician will perform to verify that the heating, ventilation, and air conditioning (HVAC) system in your vehicle is operating as it should. The procedure includes temperature checks of the air conditioning and heating system output, as well as testing of the various modes of the system to ensure that the HVAC blend door actuators are working correctly to output air at the proper locations, the vents, defrosters, and the like.
How do I know if my vehicle needs an HVAC performance check?
Some of the symptoms that might cause a technician to recommend an HVAC performance check include the following:
Your AC system will not cool the cabin as it should, or it is blowing warm air
The AC light blinks on the dashboard and a diagnostic scan reveals a trouble code fo the AC system
You do not get warm air from the vents when the heat is switched on, or you get cool air instead
You sense a fluctuation in the temperature from either the heat or AC without changing the controls
FREQUENCY OF INSPECTION
How does a technician perform HVAC Performance Check ?
While the procedure may differ slightly from one vehicle make and model to the next, a technician will generally take the following steps to do an HVAC performance check:
Measure the cabin air temperature at the dashboard vents with the engine running and the AC operating on the maximum cooling setting
Once the engine has warmed up, measure the cabin air temperature again while the heater is on its maximum setting
Connect a diagnostic scan tool to the data link in your vehicle and check for any trouble codes related to the heating or AC system
Manipulate the climate controls through all possible settings while checking to ensure that the fan directs air from the designated locations indicated on the control panel
OTHER QUESTIONS CUSTOMERS ASK
Do auto parts stores check your AC for free?
No. Auto parts stores may offer some complimentary services to customers, but AC system or recharging is not one of those services. Be advised that, when an auto parts store offers to perform a service for free, such as a diagnostic scan, it is usually with the goal of selling auto parts, not necessarily providing a comprehensive diagnosis.
How do I know if my car AC needs freon?
If your vehicle’s AC system is low on refrigerant, the AC compressor might not engage at all. That is because the system is equipped with a low pressure switch that detects low refrigerant levels in order to protect the compressor. Other signs of low refrigerant include an AC light blinking on the dashboard or insufficiently cold air coming from the vents.
How often does car AC need to be recharged?
The air conditioning (AC) system in your vehicle may never need to be recharged. The refrigerant inside the system is made to last the lifetime of your vehicle. And although a small amount of refrigerant loss over time is possible, it is not enough to impair operation of the system. How often the AC system needs to be recharged depends on a number of factors, but it should only be necessary if all system components are operational, and yet the air coming from the vents is not as cold as it should be.
