What to Do When the Car Lacks Power with Air Conditioning On?
2 Answers
The reasons for a car lacking power when the air conditioning is on are as follows: 1. Vehicle malfunction: Generally, it could be an issue with the air conditioning system. During summer, the air conditioning is used daily, so it might be a problem with the thermostat or clutch. 2. Spark plug malfunction: Spark plugs play a significant role, and different materials can achieve varying effects. Replacing them with high-quality spark plugs not only extends their lifespan but also enhances power output. 3. Engine oil issue: When there is sufficient engine oil, it provides excellent lubrication between car components. Car owners should regularly check the oil level and replenish it promptly if it's low to prevent wear and tear on car parts.
I totally get it when the car feels sluggish with the AC on. The main reason is that the compressor consumes engine power when operating, which is especially noticeable in small-displacement cars—it feels like the throttle response becomes weak. Before rushing to repairs, try turning off the AC and going uphill. If the power returns immediately, the issue lies in the AC system. For regular maintenance, remember to clean the radiator and condenser fins—blockages from pollen or dust can impair cooling, making the compressor work harder. Replacing the AC filter periodically also reduces the load. For older cars, especially check the compressor clutch and belt tension, as a slipping belt can cause greater power loss. Here’s a lesser-known tip: avoid piling too much clutter in the car to reduce weight, and even raising the AC temperature by 1 degree can save some effort.
