About Us
About Our Company
Singapore-focused air conditioning service with practical workmanship
Decom Aircon supports homeowners and businesses with aircon servicing, maintenance, and installation-related work across Singapore. We priorities clear scope, professional site conduct, and clean finishing. If there is a problem, we explain the cause and the options so you can decide based on budget and urgency, not guesswork.
Why Regular Aircon Servicing Matters
Singapore’s tropical climate and high humidity mean your cooling units work incredibly hard every single day. Unlike temperate countries, skipping air conditioner maintenance here quickly leads to trapped moisture, mold buildup, and blocked filters. This strain forces your compressor to work overtime, significantly driving up your monthly electricity bills.
The true cost of ignoring maintenance is unexpected failure when you need cooling the most. Built-up grime causes water leakage, while unchecked wear leads to severe compressor faults and gas loss. By applying our 27 years of experience and in-house cleaning techniques, a basic aircon servicing contract in Singapore with Decom Aircon prevents these expensive breakdowns before they happen.
- Prevents water leaking from blocked drainage pipes
- Improves energy efficiency to lower utility bills
- Catches minor wear before it becomes a major compressor failure
- Maintains healthy indoor air quality

Frequently Asked Questions.
For daily usage in Singapore, we recommend servicing your units every 3 to 4 months. If you only use the aircon at night, every 6 months is usually sufficient. Regular maintenance prevents heavy dust buildup and stops minor drainage blockages from turning into major leaks.
Basic servicing includes cleaning the outer panels, washing the air filters, clearing the drainage pan, and vacuuming the drainage pipe to prevent leaks. We also check your system’s overall operating pressure and temperature. This keeps your unit running efficiently and cleanly.
Normal servicing is for routine upkeep, while a chemical wash is needed when the internal coils are heavily choked with grime. If your aircon is leaking persistently, blowing weak air, or emitting a foul smell despite regular cleaning, a chemical wash is usually required to strip away the deep-seated dirt.
Water leaks are almost always caused by a blocked drainage pipe. Over time, dust and condensation mix to form a jelly-like substance that clogs the line, causing water to back up and overflow from the indoor unit. A standard service will clear this blockage using a specialized vacuum.
Our basic servicing starts from $40 per unit, with a minimum of 2 units per visit. We believe in complete transparency, so our technicians will never surprise you with hidden fees. If additional repairs or chemical washes are needed, we provide a clear quote before starting any work.
Yes, we service and repair all major brands available in Singapore. This includes popular residential models from Mitsubishi, Panasonic, and Daikin, as well as commercial systems from LG, Carrier, and York. Our 27 years of experience means we have handled almost every model on the market.
If your aircon is over 10 years old and facing a major compressor failure, replacement is often more cost-effective. However, if the issue is just a faulty capacitor, a sensor problem, or a choked coil, a simple repair can easily extend its life by several years. We will always give you an honest recommendation.
An aircon servicing contract is a scheduled maintenance agreement where we visit your property 3 to 4 times a year to clean and inspect your units automatically. You need one if you want to lock in lower per-visit rates, ensure priority booking, and avoid the hassle of remembering to call for maintenance.
Yes, we handle commercial cooling systems for offices, retail shops, and industrial spaces. Commercial usage requires a different approach due to heavier loads and longer operating hours. We offer tailored maintenance schedules to ensure your business operations are never disrupted by a breakdown.
Routine maintenance is preventative—you book it when the aircon is working fine to keep it that way. You need a full repair when the unit stops blowing cold air, makes loud grinding noises, turns off by itself, or has blinking indicator lights. If in doubt, message us on WhatsApp with the symptoms.
