Why is the sound loud when turning on the air conditioning in Haval H6?

Haval H6's loud air conditioning noise issues are: the air filter is too dirty, the baffle in the air duct is in a semi-closed state, or there's an engine problem. Air filter too dirty: First, check if the air conditioning filter is too dirty. If it is, replacing the air filter should solve the problem. Baffle in the air duct is in a semi-closed state: Another possibility is that the baffle in the air duct cannot return to its proper position, resulting in a semi-closed state. This prevents air from flowing in properly, leading to increased wind noise. Try switching the air outlet positions several times, especially to the front windshield setting. If the issue persists, a disassembly inspection may be necessary. Engine problem: Engine issues, especially with smaller horsepower and displacement, can cause noticeable power loss when the air conditioning is on, which is produced by the air conditioning operation.

I've been repairing cars for over a decade, and loud AC noise in Haval H6 is quite common. The most frequent cause is an aging cooling fan or debris like dust and leaves stuck between the blades, creating a whooshing sound when the fan spins. If the compressor is worn, it'll produce a screeching noise upon startup – this requires professional tools to diagnose. Loose belts often cause squeaky noises, which can be improved by slightly tightening the screws. A clogged cabin air filter forces the fan to work harder, increasing noise levels, so replacing it is a simple and effective solution. After parking, feel the fan area – noticeable heat or vibration indicates fan issues. Regular maintenance is crucial; cleaning the fan and replacing the filter every six months can prevent this problem. Loud noises distract drivers and compromise safety, so don't ignore it – get it checked at an authorized shop. Refrigerant leaks also make the compressor overwork and noisy. Fixing minor issues early saves money and ensures peace of mind.

I've only had my Haval H6 for two years when I noticed it gets extremely noisy with the AC on, sounding like a tractor in summer. At first, I thought it was normal, but later I couldn't stand it and took it to the 4S shop. The mechanic said dust buildup on the cooling fan was the issue and cleaning it would help. However, after six months, the noise returned. A check revealed worn fan bearings, and replacing the fan immediately made it quiet again. I bought a new AC filter myself—cheap and it reduces wind resistance noise. A broken compressor would've been expensive, luckily I didn't encounter that. A friend suggested tightening the belt under the hood also helps. Regularly clearing leaves and debris from the engine bay and cleaning the fan blades can prevent issues. The noise was so irritating while driving, affecting music enjoyment and safety—it's best to address small problems early for the most cost-effective solution.

The increased noise from the Haval H6's air conditioning is often due to fan issues: dirty blades or foreign objects can cause noise; worn fan bearings produce continuous noise. Compressor failure is also common, with abrupt sounds upon startup. When the air filter is clogged, the fan speed increases, leading to louder noise. Checking is simple: observe if the fan runs smoothly after turning off the AC. If the noise is localized to the fan area, clean the blades; if the filter is dirty, replace it. Minor issues can be handled DIY, but complex problems like compressor damage require professional technicians. Daily prevention is key, with regular maintenance reducing risks.
