Recharging the A/C System: Over time, the refrigerant in your A/C can escape or degrade, leading to poor cooling. Identifying and Fixing Leaks: Leaks in components such as hoses, seals, or the condenser can prevent the A/C from cooling properly. Detecting and repairing leaks is essential to ensure the A/C system functions correctly. Replacing the A/C Compressor: The compressor is the heart of the A/C system. When it fails the system does not circulate refrigerant effectively. Swapping Out the Condenser: The condenser helps release heat from the refrigerant. If damaged or clogged, it can prevent effective cooling. Replacing the condenser restores optimal heat dissipation. Evaporator Core Replacement: The evaporator absorbs heat from inside the cabin. If it leaks or clogs, the A/C may stop cooling or produce strange smells. Replacing a faulty evaporator core restores cooling and air quality. Fixing or Replacing the Blower Motor: The blower motor pushes air through the vents. If it ... read more

Spark plugs may be among the tiny components of your car’s engine, but they play an important function in keeping your vehicle operating smoothly. These tiny devices ignite the air-fuel mixture inside your engine’s cylinders, powering every drive you take. At Frank’s Auto Service and Repair we offer professional spark plug inspection, repair, and replacement—backed by our 36-month/36,000-mile nationwide warranty. If your car’s engine runs rough, fuel efficiency has dropped, or your car struggles to start, the spark plugs might be worn or faulty. Common signs also include engine misfires, sluggish acceleration, strange rattling sounds, and an illuminated check engine light. If you don't take care of the problem in a timely fashion, catalytic converter or engine may suffer damage. Heat, pressure and residue accumulation will eventually cause the spark plugs to wear out and fail to generate the strong spark your engine needs. Most vehicles require new s ... read more

Tire pressure monitoring sensor (TPMS) is a device that alerts your vehicle’s computer if the tire pressure falls below designated threshold – usually if it is down over 20% - 25%, you will notice TPMS warning light on the dashboard. But sometimes, even though the tires are fine, the TPMS warning light still comes “on” – this usually indicates problem with the sensor itself. At Frank’s Auto Service and Repair we can inspect your vehicle’s tires and determine if it’s the sensor or if one or more tires are indeed underinflated. Underinflated tires are a potential safety hazard, so we strongly suggest not ignoring the TPMS warning light. When it is safe to do so, we recommend stopping the vehicle and visually inspecting the tires. If you have a portable tire pressure gauge, this is a good time to check all four tires. If the gauge indicates low tire pressure, a portable air pump, powered from the cigarette lighter in your car, could get the ... read more
