Air conditioning provides dehumidification of the interior and stabilise the temperature. A common misconception is that aircon is only for cooling purposes – this is simply not true, as it can be used all year round and is useful in winter months to prevent the windows misting up.
Aircon is standard on all Jazz models except the S model, where it was/is offered as a dealer-fit option. Because the installation cost is greater then the price differential between the S & SE model (with aircon), few if any customers opted for this pricey option.
Jazz SE & SE Sport models (and S model with dealer-fit aircon) are fitted with a manual system which pumps coolant when the switch marked A/C is pressed. The Sport model (and some JDM imports) come fitted with an electronic climate control system which if left in FULL AUTO mode, automatically switches the aircon on or off as needed to maintain the temperature as set by the up/down temperature controls (e.g., 20 C).
Effects on Fuel Consumption & Performance
There is some debate as to whether aircon should be used all the time or just when needed. Although aircon can increase fuel consumption and reduce performance, it is not known by how much this will occur or even if it would be noticeable. Therefore, it’s really up to you and your personal preference, although on models fitted with climate control its best to leave the system in FULL AUTO model during normal usage and yet the electronics look after it all.
Reliability
Aircon systems are generally reliable, but there are a few pointers to remember. Firstly, the system may need topping-up with coolant from time-to-time, depending on how often it’s used. Operating the aircon with little or no coolant could damage the compressor; so if the system is no longer pumping out cool air when set to maximum cold temperature, have the system inspected by a technician (not necessarily your Honda dealer, who often contract aircon work out to another company) who can advise the best course of action. As a general rule, the system should not need topping up within the first three years but it’s impossible to say what’s ‘normal’.
Regular use can keep the system working perfectly so keep it running for at least 10 minutes once a week. It can also reduce the chance of mould growing in the system which has obvious health risks. For this reason, any suspicious smells produced when the aircon is in operation, especially mouldy or damp odours, should be investigated. Also avoid opening the windows and sunroof (if fitted) when the aircon is in use as this affects performance of the system.
The aircon is not serviced as part of your Jazz’s scheduled servicing, so have the system checked every three to four years. As stated in the owner’s manual, the system should be recharged using Refrigerant HFC-134a (R-134a).
