Five Tips for Optimal Operation of Your Car’s Air Conditioning System

ac serviceTemperatures over 90 degrees and high humidity can challenge your vehicle’s air conditioning system. Here are five easy tips from the Mobile Air Conditioning Society (MACS) Worldwide to keep you and your passengers cool on the road.

1. If possible, leave the windows down slightly on hot days to reduce heat build-up. An A/C system works by removing heat, so the cooler the interior is to start with, the easier and faster the A/C will do its job.

2. When you get in the car, open all the windows completely, or even open the doors, for a moment to vent the hot interior air quickly.

 3. When you first turn the A/C on, set the controls to MAX or REC and use highest blower speed. This moves the greatest volume of air and re-circulates it for even faster cool-down.  As soon as you are comfortable, switch the system to NORM or OUTSIDE or FRESH, and select a lower fan speed. The lower blower speed produces colder the air from the system.

4. Does your cool air have a bad odor, perhaps like “dirty socks” or a gym locker? Remember to set the system to the OUTSIDE air mode (not REC) frequently to help prevent or lessen this problem.

5. Automatic Temperature Control systems operate differently than manual systems. Read your owner’s manual to gain understanding of exactly how your system works.
With most automatic systems, the quickest cool-down comes by setting the temperature as low as it will go at first, then adjusting it later to occupant comfort.

Air conditioning problems should be diagnosed by a professional service facility with the proper tools, training, and certified technicians.

Here at A.J. McKay’s Auto Repair we have the tools and experience to keep your auto A/C running cool all summer.

Getting Your Vehicle Ready For Summer


Summer's heat, dust, and stop-and-go traffic, will take their toll on your vehicle. Add the effects of last winter, and you could be poised for a breakdown. You can lessen the odds of mechanical failure through periodic maintenance...Your vehicle should last longer and command a higher resale price, too!

Some of the following tips are easy to do; others require a skilled auto technician.


Front-Drive Axles

front-drive-axlesThat clicking noise that your front-wheel-drive car makes as you accelerate around low-speed righthand corners has been getting a little louder for weeks. One afternoon, just as you pull out of the parking lot, there's a loud banging noise and a series of crunches. Then all forward thrust drops off, punctuated by vibration and the occasional ping of tortured metal. Your CV joint has failed.



  • You have an auto problem? - GO TO A.J. (PERIOD!)

    AJ was very honest and spot on!- he told me brakes when AAMCO said differential rebuild. AJ fixed it!

  • Simply the best!

    After moving to Phoenix from Massachusetts I was concerned that I would have a tough time finding a good mechanic. Fortunately yahoo user reviews pointed me to McKay auto. I have always felt that AJ has charged me a fair price and unlike other shops he doesn't try to sell you things you don't need. This business practice will keep me coming back as well sending others his way. Even though his shop is a distance from where I live I will still make the drive in order to ensure my car get's taken care of. A plus is he has a Toyota certified mechanic on site so I knew my Lexus would be repaired properly. Thanks AJ.

  • Someone you can trust

    HONESTY pure and simple. My truck would not start and thought my starter motor or solenoid, ignition switch may be at fault. Had it towed to A J McKay's Auto Repair and it was a simple 25 cent fuse which he replaced at no charge and no charge for the diagnostic of the problem. Many other shops would have 'found something wrong' and charged me an arm and leg to fix a non-existent problem. I will take my two cars and truck to them from here on out. Just outstanding, honest, personal gentlemen that care for and about the customer! In fact, I'm taking my Nissan there tomorrow for some work. These guys are simply outstanding!!!
