Car AC: Summer temperatures can render driving nearly impossible without AC, but improper settings can increase fuel expenditure. A few simple habits can provide superior cooling and save petrol too. How much AC speed to use can make a significant impact on your wallet and comfort.
Which AC Fan Speed is Best
Cars that have manual AC controls perform best at low or medium fan speed, say levels 1 or 2. The speed is enough to cool the cabin while ensuring engine strain does not get out of hand. Settings like 3 or 4 push the blower to consume more power, compromising engine performance and fuel efficiency.
Correct Temperature Settings for Auto AC
If your vehicle has automatic air conditioning, it’s generally optimal to set the AC from 24 to 26 degrees Celsius. This temperature maintains cabin comfort without overloading the AC. The compressor remains stable, which aids in fuel consumption reduction.
Smart Tricks to Conserve Fuel While Running AC
Vent Out Hot Air First
If the car has been parked in harsh sunlight, open windows for a short time before turning on the AC. This allows hot air to escape and helps the AC cool the cabin faster with less effort.
Use Recirculation Mode
This mode reuses cooler air already within the vehicle, instead of drawing hot air from the outside. Because of this, the cabin will cool rapidly and the AC is not overworked, which saves fuel.
Run AC Only When Needed
Do not operate the AC when the weather is not hot and the outside air through the blower is sufficient. This little behavior can produce a great deal of fuel savings in the long term, particularly on short trips.
AC Maintenance and Service
Regular Servicing
Servicing the AC at periodic intervals keeps the cooling system in good condition. Clean filters, correct gas pressure, and a well-functioning compressor mean the engine does not have an additional load, providing you with improved mileage.
Check for Leaks
Low cooling can, at times, be a result of gas leaks or corroded pipes. Replacing them early will not only make the AC better but also avoid increased fuel expenses associated with a struggling compressor.
