How Many Hours Can AC Run Continuously?
Wondering how many hours an AC can run continuously? Learn safe usage tips, servicing needs, and expert support from LG AC Service Center.

Introduction
Air conditioners have become an essential appliance in most Indian households, offering comfort during scorching summers and humid monsoons. A common question many users have is: How many hours can an AC run continuously without causing any harm? To address such queries and ensure smooth usage, customers often rely on trusted service centers. That’s where the LG AC Service Center plays an important role in providing reliable solutions, expert advice, and timely maintenance.
Can You Run an AC Continuously?
Yes, you can run your AC continuously for long hours, even up to 24 hours a day, if needed. Modern LG ACs are designed with advanced compressors and energy-efficient technology that allow them to operate for extended periods without damaging the system. However, several factors influence whether continuous usage is advisable, such as room size, outside temperature, electricity load, and maintenance condition of your AC.
Factors That Affect Continuous AC Running
1. Type of AC
-
Split ACs: Built for efficiency, these can run longer without overheating.
-
Window ACs: Slightly less efficient but can still handle prolonged use if serviced regularly.
-
Inverter ACs: These are designed for continuous operation as they adjust compressor speed based on room temperature.
2. Maintenance Status
An AC with clean filters, serviced coils, and adequate refrigerant levels can run longer without strain. If neglected, continuous usage can lead to inefficiency, higher power consumption, and potential breakdowns.
3. Room Size and Insulation
If your room is large or poorly insulated, the AC will work harder, causing strain during continuous operation. Proper insulation allows smoother performance even with prolonged usage.
4. Power Supply Stability
Running an AC continuously requires a stable power supply. Voltage fluctuations may damage the compressor over time.
5. Ambient Temperature
In extremely hot conditions, your AC may work harder to maintain cooling. This can shorten its ability to run continuously without rest.
Is It Safe to Run AC 24/7?
Running an LG AC for 24 hours is generally safe if the unit is well-maintained. Inverter models, in particular, are built for longer usage since they don’t operate on the constant on-off mechanism of traditional ACs.
However, continuously running your AC has some drawbacks:
-
Higher electricity bills
-
Wear and tear on components
-
Possible overheating if not serviced
-
Faster filter clogging
This is why timely servicing becomes essential. Whether you live in Mumbai, Thane, or Bengaluru, you can always rely on the LG AC Service Center for professional maintenance.
How to Increase the Lifespan of Your AC
1. Regular Servicing
A professional check-up every 6 months ensures that filters, coils, and compressors are in perfect condition.
2. Use a Timer
Instead of running your AC all day, use timers to give the system short breaks.
3. Keep Surroundings Clean
Dust-free surroundings reduce the chances of filter blockages and allow efficient airflow.
4. Set Optimal Temperature
Running your AC at 24–26°C is ideal for balancing comfort and energy savings while reducing strain on the unit.
5. Ensure Proper Installation
Improper installation can cause inefficiency and strain. Always rely on authorized technicians from trusted service centers.
