The A/C Is Making Noise

An A/C unit makes noise as the air blows through the system, warming or cooling your vehicle. But it may need repairs if you hear unusual sounds from the A/C. You might notice a loud grinding or screeching sound when you turn on the air, which could precede a complete system failure. Anytime the A/C is loud enough to drown out the conversations inside the car, you need to service it.

The compressor is often a problem, but the noise could also come from the fan motor or another system part. Excessive wear and tear and age can cause the A/C system to stop functioning altogether. If it makes noise, it’s time to bring it in for service or repair.

The Air Isn’t Cold

If you turn on the A/C expecting a cool breeze and the air is warm instead, your car’s A/C system needs repair or replacement. Of course, before you panic, check the thermostat settings to ensure you don’t have the heater on.

Many things can cause the A/C to not cool properly, including low refrigerant, a clogged tube or hose, or a blown fuse. A broken compressor, blower motor, condenser, or evaporator are a few more serious problems to consider.

There’s Inadequate Cooling in Certain Areas

Your car’s A/C system should cool the entire interior of your vehicle. If certain parts of your car are much warmer than the rest, the A/C isn’t doing its job properly. Similarly, in the winter, the heater should evenly warm the vehicle. If not, there could be a blockage in the system, or some components may need replacing.

Before you take your vehicle in for repairs, check the thermostat settings. Setting the thermostat to extreme temperatures can cause the A/C to work too hard and overheat. Next, check all the vents in your car. If the back seats aren’t getting any warm or cold air, someone may have closed them. If there’s not much air from the vents, having our technicians at Performance Honda check the A/C is a good idea.

The Airflow Is Weak

The A/C might be blowing cold and hot air, but the airflow isn’t as strong. Built-up mildew can cause weak airflow in the A/C system’s evaporator core, but it may also be something as simple as a loose blower hose. There might also be a problem with the seals in the system, causing air to leak. Fortunately, your mechanic can replace leaky seals or hoses. In the worst-case scenario, you’ll need to replace the ventilation fan.

There Are Unusual Smells

It’s common to notice unusual smells when you drive, whether it’s new asphalt, gasoline, someone’s exhaust, or a skunk. But if the unusual smell lingers in the car while driving, it may come from the A/C unit inside your car. A refrigerant leak can cause strange odors. It could also mean you need to change out the cabin air filter.

Mold or mildew inside the evaporator or air vent can also cause an unpleasant odor. Since mold and mildew are health hazards, it’s important to ensure they’re not the cause of the odor. It may be enough to have the service technician clean the evaporator case and air vent to eliminate the unpleasant smells.

A burning odor can be a sign of damaged or overheated wiring. If you notice a burning smell when the A/C runs, that’s a serious problem. Turn the A/C off and schedule an appointment to have a technician check it.

The Refrigerant Is Leaking

The refrigerant in your vehicle’s A/C system keeps the interior cool. If refrigerant leaks, there’s a chance you need to replace one of the seals or hoses. Even if you don’t see any visible signs of leaking refrigerant, you may notice your car isn’t cool even after the A/C has been running for a while.

There’s Moisture on the Dashboard

When a hose has a clog, it can prevent the water from draining properly, leading to moisture leaks. If you notice a water stain or visible moisture on your car’s dashboard, it could be a sign the A/C system isn’t working correctly. To avoid damaging any other components in your vehicle, you should take the car to a service technician as soon as possible and refrain from using the A/C system.

How To Maintain the A/C System

The A/C system in your car needs proper prevention and maintenance care, just like the rest of the vehicle. It’s a good idea to do a system check once a year. You’ll also want to check the fluids with every oil change and ask the technician to check for leaks. If you notice any unusual noises, leaks, or lack of airflow, it’s essential to take the vehicle to a mechanic right away.

When To Repair the A/C in Your Vehicle

If the A/C system isn’t keeping you warm this winter in Fairfield, Ohio, it’s time to take the car to a reputable mechanic.
