Service | Graham, TX The warning signs your AC is fading, the usual causes and what the Graham shop looks at first. The first triple digit week in Young County has a way of exposing every air conditioner that has been quietly giving up. The vents still blow, but the air is warm by the time you reach the stop light on Highway 380. Holiday Chrysler Dodge Jeep Ram lists air conditioning and heater service and cooling system repair among the work its Graham service department does. This post explains what usually goes wrong and why mid May is a better time to find out than July. Quick answer: If your AC blows warm, weak or smelly air, have the system inspected before summer heat arrives. Low refrigerant usually points to a leak, and adding more doesn't repair it.

Keeping the cabin cooler between repairs What are the signs your AC is on its way out? Warm air is the obvious one. Less obvious signs show up earlier, like air that takes longer to cool down, a weaker flow from the vents or a system that cools well on the highway but warms up at a stoplight. Listen and smell too. Clicking or rattling from under the hood, a musty smell when the fan starts or moisture inside the cabin all point to something specific the tech can find. Warm air: the system may be low on refrigerant or have a failing part. Musty smell: moisture in the system or a dirty cabin filter. Loud noise when the AC turns on: the compressor or clutch may be wearing out. Why does the AC fade on the hottest week? Because that's when it works hardest. A system with a small leak or a tired part can keep up in 80 degree weather, then fall behind at 100 when the load is highest. Heat finds the weak spots. A cooling system that's already marginal, a clogged condenser at the front of the car or a failing fan show up fast once the thermometer climbs. Trucks and SUVs add another wrinkle. A big cabin with a lot of glass takes longer to cool, and a vehicle that sat in a sunny parking lot all day can get far hotter inside than the air outside. Even a healthy system needs a few minutes to catch up. Graham tip: Don't wait for July. Shops get busy when the first hot week arrives, and a May appointment is easier to find than one on the Friday before a holiday. Can a recharge can fix a weak AC? Sometimes it makes the air colder for a few days, and that's the trap. An AC system is sealed, so if it's low on refrigerant, the usual reason is a leak. Adding more just feeds the leak. Overfilling is a risk as well. Too much refrigerant can raise pressures and hurt the compressor. A shop can find the leak, repair it and charge the system to the right amount. An AC system is sealed, so if it's low on refrigerant, the usual reason is a leak. What does an AC check at the shop involve? It starts with a conversation about what you've noticed. Then a tech checks pressures, looks at the compressor, hoses, condenser and fans and tests for leaks. The cabin air filter is worth a look too, since a clogged one weakens airflow. Because the cooling system and the AC share parts like the front fans, the shop may check coolant and the radiator while it's in there. 1 Describe it. Tell the advisor when it's weak, how it smells and whether it changes with speed. 2 Test. The tech checks pressures and looks for leaks and failed parts. 3 Explain. You get the findings and the options before any repair begins. Keeping the cabin cooler between repairs Park in shade when you can and use a sunshade on the windshield. On a hot day, open the windows for the first minute before you turn on the AC so the heat can escape. Set the system to recirculate once the air gets cool, and replace the cabin filter on the schedule in your manual. Those habits help any AC system, healthy or not.
