AIRCON GAS TOP-UP
Aircon Gas Top-Up in Singapore
In Singapore's hot and humid climate, air conditioners work hard to keep indoor spaces comfortable. Over time, the refrigerant gas in your aircon may deplete, leading to reduced cooling efficiency. Our gas top-up service ensures your aircon operates at optimal performance.
Why Is Aircon Gas Top-Up Necessary?
Refrigerant gas is essential for your aircon to cool effectively. Low gas levels can result in:
-
Longer time to cool the room
-
Increased electricity consumption
-
Potential damage to the compressor
-
Reduced overall lifespan of the unit
Regular maintenance and timely gas top-ups help prevent these issues.
