When the mercury begins its annual climb toward triple digits, there’s nothing more important to you than an air conditioner that works well. And, even if you think your car’s air conditioner is doing its job, an annual spring checkup is usually a good idea.

Generally that includes checking the car’s cooling system, to make sure it’ll handle the extra load of the air conditioner while driving in already high temperatures. And it’ll include checking the condenser for anything that might be blocking air flow, and the cooling fans to make sure they’re coming on and moving adequate air when you turn the A/C on.

It’ll also include checking the fan belt that operates the air conditioning compressor, to make sure it’s in good condition and tight enough to keep the compressor turning at the proper speeds.

It may also involve checking system pressures. While most of today’s air conditioning systems don’t have a sight glass, good technicians can still get a reasonable idea of the system’s charge by check the operating pressures against the outside temperature.

From there they’ll move inside the passenger compartment, to make sure the system is operating properly and all the doors in the system ducts are opening and closing properly, to make sure you’re getting full value from your air conditioning system.

Finally, many of today’s cars have a cabin filter, to filter the air coming into the passenger compartment, this is the air your breath when your windows are closed. While the air conditioning may still work with a dirty cabin filter, replacing it will provide more air flow and better climate control.
