Be cool. An inspection of your car’s air conditioning system this time of year at a local auto mechanic shop, by a certified Automotive Service Excellence (ASE) mechanic, can insure you don’t have to sweat the summer, and it could head off big repair bills down the road. Remember, in most cars the air conditioning is also working when you turn on the defroster, even in the winter months.
Phil Sanders, who has worked on cars since he was 13 and has owned local Gilmore’s Auto Service in Walnut Creek, CA, since 1977, says failure to cool can result from too little Freon, which can also cause costly damage to the compressor that depends on the liquid’s lubrication, or too much Freon. Too much Freon raises the internal pressures and prevents accurate functioning of the air-conditioning system. Inferior grades of Freon can make the problem worse. A clogged filter can limit air flow. In areas with highpopulations of flying bugs, the condensing unit in front of the radiator can become clogged. In addition to overall poor cooling, a squealing belt or noisy compressor can indicate trouble. Also, a system that cools well for the first few minutes and turns lukewarm likely has some problem with the Freon, condenser or compressor
The Gilmore’s Auto Service inspection includes measuring vent air temperature; detecting Freon leaks in hoses, compressor seals, condensing unit, and evaporating unit; checking for external and internal blockages; and confirmation that pressure levels are correct in the air-conditioning system. The diagnosis takes 30 to 60 minutes, including a Freon recharge if necessary.
Preventive maintenance might be a low priority in the family budget, but an economical checkup before summer heats up can help you keep your cool and avoid major repair bills all year.
