Is Your Aircon Trying to Tell You Something?
Your air conditioner works hard to keep your home cool, but like any machine, it needs regular maintenance to function at its best. Many homeowners in Singapore only call for servicing when their aircon stops working completely—but by then, the damage (and the repair cost) may already be significant.
Ignoring early warning signs can lead to higher electricity bills, poor air quality, and costly breakdowns. Here are 10 clear signs your aircon needs servicing ASAP.
Weak or Warm Airflow
If your aircon isn’t cooling as effectively as before, something is wrong. Warm or weak airflow could be caused by:
Clogged air filters blocking circulation
Refrigerant gas leaks, reducing cooling power
Compressor failure, leading to system inefficiency
A quick servicing session can fix these issues before they worsen.
Strange Noises Coming from the Unit
A well-functioning aircon should operate quietly. If you start hearing rattling, clicking, buzzing, or grinding sounds, your aircon may have:
Loose or broken fan blades
A failing compressor
Obstructions in the motor or vents
Ignoring these noises could lead to a total breakdown, requiring expensive repairs.
Unpleasant Smells When You Turn It On
Bad odors coming from your aircon indicate mold, bacteria, or gas leaks. Common causes include:
Musty smells → Mold and bacteria buildup
Burning smells → Overheating or wiring issues
Chemical smells → Possible refrigerant leaks
A chemical wash can eliminate bacteria, mold, and allergens, restoring clean airflow.
Water Leaking from the Aircon
If you notice water dripping from your aircon, it’s likely due to:
Clogged drainage pipes, causing water buildup
Frozen evaporator coils, leading to excess condensation
Faulty installation, making the unit drain improperly
Water leaks can damage your walls, floors, and furniture. Get it fixed immediately!
Higher Electricity Bills Without Explanation
Has your electricity bill increased even though your usage hasn’t changed? A struggling aircon works harder to cool your home, consuming more power. Possible causes include:
Dirty filters blocking airflow
Low refrigerant levels
A failing motor or compressor
Regular servicing can reduce power consumption by up to 20% and keep your bills in check.
Your Aircon Cycles On and Off Frequently
Does your aircon keep turning on and off repeatedly? This “short cycling” can be caused by:
Thermostat issues, sending incorrect temperature signals
Refrigerant leaks, making the system overwork
Overheating components, triggering automatic shutdowns
Ignoring this can shorten the lifespan of your aircon and lead to expensive repairs.
Inconsistent Cooling Across the Room
If one part of the room is cool while another feels warm, your aircon may have:
Dirty air filters restricting airflow
Blocked ducts or vents
A malfunctioning thermostat
A quick servicing session can restore balanced cooling.
Ice Buildup on Your Aircon
If you see ice forming on your aircon’s pipes or vents, it means the unit is struggling. Causes include:
Low refrigerant gas levels
Restricted airflow due to dirty filters
Faulty blower motors
Running an aircon with ice buildup can permanently damage the system. Book a servicing before it's too late!
Frequent Tripping of Circuit Breaker
If your aircon keeps tripping the circuit breaker, it may be drawing too much power due to:
A faulty compressor
Electrical wiring issues
Overloaded power circuits
This is a fire hazard, so don’t ignore it! Call a technician for immediate servicing.
Your Aircon is Overdue for Servicing
If it’s been more than 6 months since your last aircon servicing, it’s time to schedule one. Even if there are no visible problems, dust and bacteria accumulate inside, affecting cooling efficiency and air quality.
