Air conditioners are essential in most HDB flats. However, when they break down, not all homeowners know that specific rules and guidelines apply to aircon repair—especially within public housing estates. Understanding these standards helps to avoid penalties, safety concerns, and disagreements with neighbours or contractors.
Discover what HDB flat owners need to know before engaging in aircon repair in Singapore.
HDB Requires BCA-Certified Installers and Repair Technicians
HDB strictly mandates that only BCA-trained technicians or contractors registered under HDB’s Directory of Renovation Contractors (DRC) are allowed to perform aircon-related works. This mandate includes installation, replacement, and major repairs. The reason is to ensure safety, structural integrity, and compliance with public housing standards.
Homeowners must verify that the company or technician has proper qualifications. Non-compliance can result in HDB rejecting future renovation permits or holding the owner liable for damages. This rule applies even if the issue seems minor, such as a water leak or gas refill, so long as it involves accessing internal piping or external trunking.
Drilling and Mounting Works Require Caution
Most aircon systems, especially split units, involve piping that routes through walls or ceilings. HDB approval may be needed if repair or reinstallation involves drilling, especially on external walls. This requirement is because HDB flats share structural walls that cannot be compromised.
Aircon repair often includes re-routing of pipes or changing wall brackets. In these cases, workers must not drill into reinforced concrete or structural beams. Using hammer drills on load-bearing structures is explicitly disallowed unless certified and approved. Improper drilling can affect structural safety and lead to costly liabilities.
Condenser Unit Placement Is Regulated
Some air conditioning repair services include replacing or relocating the condenser (outdoor) unit. In HDB flats, there are designated ledges or brackets where these units must be installed. It is illegal to place them in locations not approved by HDB, such as common corridors, window grilles, or makeshift shelves.
Placing condensers in older HDB flats without aircon ledges requires additional submission to HDB, including structural calculations. Failure to comply can result in enforcement action and may also pose a danger to pedestrians or neighbours below.

Noise and Water Drip Complaints Are Enforceable
One often overlooked area of aircon repair is the handling of drainage and system noise. HDB owners are responsible for ensuring that drainage pipes do not leak or drip onto other units. During a repair, technicians must check that water flows properly through internal pipes into designated drainage outlets.
In addition, older units or poorly repaired systems can emit high operational noise. HDB has received complaints over units vibrating against bedroom walls or causing disturbances at night. These issues fall under neighbour dispute resolutions and can involve town councils if not resolved amicably. Homeowners should ensure that repaired or replaced units are properly mounted with anti-vibration pads and that noise levels stay within acceptable limits.
Gas Top-Ups and Refrigerant Handling Must Follow Safety Standards
Aircon repair services that involve refrigerant gas top-ups must adhere to NEA and BCA regulations. Some older models still use R22 gas, which is being phased out due to environmental concerns. Technicians must ensure that replacement gases are compliant and that any leaks are sealed before charging.
Unqualified individuals handling refrigerants risk causing environmental harm, fire hazards, or personal injury. This risk extends to liability for damage to neighbouring units or shared structures in the event of an accident. Always ensure the service provider follows proper safety procedures during refrigerant handling.
Conclusion
Aircon repair in Singapore involves more than just technical expertise—it also requires compliance with HDB, BCA, and NEA regulations. HDB apartment owners must exercise caution when engaging in aircon repair services to ensure safety, legality, and long-term system function. Cutting shortcuts on requirements might result in structural damage, neighbour complaints, and even legal concerns. Always verify credentials, be aware of drilling and placement constraints, and ensure noise and drainage compliance. Remember, responsible upkeep in public housing protects your apartment and the entire neighbourhood.
