Nobody enjoys getting into that hot, humid-smelling car. While it goes through properly maintained air conditioning, your cabin becomes cool, comfortable, and odor-free. Best of all, many AC maintenance tasks can be done at home!
In this guide, we will show you in easy DIY ways how to keep your car’s AC fresh and cold, and when to call professionals.
DIY Car AC Maintenance Importance
Regular AC maintenance helps you in many ways, such as:
- Prevent Expensive Repairs
- Increase Cooling Efficiency
- Avoid Stench
- Prolong AC Life
- Save Fuel
DIY maintenance is essential for air conditioners to work in Dubai’s climatic conditions since they have to work overtime. Without maintenance, the air conditioner may lose its power, leak refrigerant, and let the germs spread from inside. Let’s discuss what you can do at home.
How to Keep Your Car AC Cold & With Fresh Air
1. Replace or Clean the Cabin Air Filter
The cabin air filter traps dust, dirt, and allergens. If not changed for a long time, it gets clogged and there might be a nasty musty smell or probably weak airflow.
DIY Procedures:
- Find the filter at the back of the glovebox or underneath the dashboard.
- Pull it out and inspect whether it is too dusty or discolored.
- Replace it if it’s dirty (every 12,000–15,000 km or annually).
Pro Tip: A clogged filter is the #1 reason why your car stinks with the AC on.
2. Clean AC Vents and Dashboard Area
The bacteria and mold often grow inside the dirty AC vents, creating foul smells.
DIY Procedures:
- Gently brush the vents or vacuum the vents using a narrow nozzle.
- Spray an antibacterial vent cleaner inside the ducts.
- Disinfect the dashboard and surrounding surfaces with disinfectant wipes.
3. Run the AC Weekly – Even in Winter
Run the AC for 10 to 15 minutes at least once a week. It will keep the compressor and seals lubricated, which prevents gas leaks and keeps the system in good health.
4. Use Recirculate Mode Wisely
The recirculate option allows the cooling of air fast inside the car. However, overuse can keep moisture and odors trapped.
Best Usage:
- Use on hot days for fast cooling.
- Turn it off for long trips to allow fresh air inside.
5. Check and Clean the AC Condenser
The condenser sits behind the front bumper and dissipates heat. If it is clogged with debris, reduced cooling occurs.
DIY Procedures:
- Open the hood and locate the condenser.
- Use a garden hose to wash away dirt and bugs.
- Gently brush the remaining debris.
6. Keep an Eye on Low Refrigerant Signs
Low AC gas levels mean poor cooling and possible compressor damage.
DIY warning signs:
- Warm air from the AC vents
- Compressor not engaging
- Frost on pipes near the engine
7. Use AC Disinfectant Spray
If there is a mildew smell in your car, it could be due to mold inside the AC system.
DIY Maintenance:
- Set the AC on max with closed windows.
- Spray AC disinfectant into the outside air intake (located at the base of the windshield).
- Let the car run for 10 minutes, circulating the spray.
- Switch off the engine to let air in through the open doors.
8. Early Detection of Possible Leaks
AC pipes, seals, or compressors are susceptible to leaks. If untreated, they affect cooling and damage the system.
What to Look For:
- Hissing or bubbling noises
- Oil stains in the engine compartment
- A Sudden drop in cold air supply
When To See A Car AC Expert
While these DIY car AC maintenance steps can help at home, professional service is required for the following reasons:
- There is a smell of gas, molds, or burning plastic from the AC system
- There are loud noises from the vents or the compressor
- There are indications of refrigerant leaking
- Sudden cooling has stopped
- The AC has not been serviced for over 12 months
Final Tips For Keeping Your Car’s AC in Good Working Condition
- Park in shaded places
- Use sunshades for a cooler cabin
- Allow your car to ventilate before switching the AC on
- Refrain from smoking or consuming odoriferous foods inside the car
- Get your AC service done every 12 months
