Common Mistakes During Aircon Installation

Aircon Installation


Air conditioner installation is a critical step that directly affects cooling performance, energy efficiency, and long-term durability. In Singapore’s hot and humid climate, even small installation mistakes can lead to frequent breakdowns, higher electricity bills, and problems like aircon not cold, aircon water leakaging, or aircon light blinking. Many homeowners focus on brand and price but overlook the importance of proper aircon installation Singapore standards. Below, we explore the most common mistakes during installation and how to avoid them with professional support from LetsCool Aircon and Services Singapore.

Incorrect Placement and Sizing of the Aircon Unit


One of the biggest mistakes during aircon installation is choosing the wrong unit size or placing it incorrectly. An undersized aircon struggles to cool the room, while an oversized unit cycles on and off too frequently, wasting energy and reducing comfort. Both scenarios often lead to complaints like aircon not cold and unnecessary aircon repair Singapore calls.

Poor placement of indoor units can also restrict airflow. Installing an aircon too close to walls, ceilings, or direct sunlight reduces efficiency. Outdoor condenser units placed in poorly ventilated areas may overheat, leading to frequent aircon error code alerts and the need for aircon compressor servicing earlier than expected.

Professional installers assess room size, heat load, and airflow direction before installation. Companies offering best aircon servicing Singapore standards, like LetsCool Aircon and Services Singapore, also plan installation layouts that reduce future issues and support smooth aircon general servicing.

 

Poor Piping, Drainage, and Gas Handling


Improper piping and drainage work is another common installation mistake that causes long-term problems. If copper pipes are bent incorrectly or not properly insulated, refrigerant flow becomes inefficient. This can result in aircon not cold situations and frequent need for aircon gas top up, which should never be a regular requirement if installation is done correctly.

Drainage mistakes are equally serious. Incorrect gradient or loose drain pipes often cause aircon water leakaging, damaging walls, ceilings, and furniture. Many homeowners mistake this as a maintenance issue, but the root cause is often poor installation.

 

 

Gas charging errors during installation are also critical. Overcharging or undercharging refrigerant affects cooling performance and may trigger aircon light blinking or aircon error code warnings. In severe cases, it can damage the compressor, leading to costly aircon spare parts replacement or full aircon compressor servicing.

Reputable installers follow proper vacuuming and pressure testing procedures, reducing the need for early aircon chemical wash or aircon chemical overhaul due to contamination or oil issues.

Skipping Professional Testing and Future Maintenance Planning


Many installers rush the final stage and skip comprehensive testing after installation. Without proper testing, issues like loose electrical connections, poor drainage flow, or gas imbalance may go unnoticed until the system starts malfunctioning. This often leads to repeated aircon repair Singapore visits within months of installation.

Another major mistake is not planning for regular maintenance. Even a perfectly installed aircon needs periodic emergency aircon service to maintain performance. Without routine aircon general servicing, dust buildup and bacteria growth can reduce cooling efficiency and indoor air quality. Over time, homeowners may require intensive services like aircon steam wash or aircon chemical overhaul, which could have been avoided with proper care.

Choosing an installer who also offers an aircon service contract ensures long-term reliability. With a service contract, regular inspections, aircon chemical wash, and early detection of issues are included, reducing unexpected breakdowns. Many trusted companies also provide seasonal aircon promotion packages that make maintenance more affordable.
