Can Poor Installation Ruin Your New Aircond?
By JBCoolCare – jbcoolcare.com
Buying a new air conditioner is a great investment—especially in Malaysia’s hot and humid climate where cooling isn’t a luxury anymore, it’s a necessity. But here’s something many homeowners don’t realize:
👉 A brand-new, high-quality aircond can fail in less than a year if it’s installed poorly.
Whether you bought Daikin, Panasonic, Midea, Sharp, or Gree, the installation quality determines up to 70% of your aircond’s performance and lifespan. Even the most expensive unit can underperform or break down simply because the installer cut corners.
In this guide, we’ll unpack how poor installation can damage your aircond, the warning signs to look out for, and how choosing a professional team like JBCoolCare ensures your aircond cools efficiently for years.
1. Poor Installation Causes Gas Leaks — the #1 Aircond Killer
One of the most common consequences of bad installation is refrigerant leakage.
Why does this happen?
- Copper pipes are not flared properly
- Connections are not tightened securely
- Low-quality copper piping is used
- Piping is bent incorrectly
- No vacuuming is done before releasing gas
When refrigerant leaks, your aircond will:
- Blow warm air
- Freeze the coils
- Consume more electricity
- Put pressure on the compressor
- Eventually burn out the compressor
And compressor damage is expensive. Replacing it can cost between RM400–RM800, depending on the model.
All of this can be avoided with a proper installation procedure.
2. Skipping Vacuuming Leads to Moisture and System Damage
Professional installers always vacuum the copper piping for 15–20 minutes before starting the system.
Poor installers skip this step to save time.
When there’s no vacuuming:
- Moisture remains inside the pipes
- Air mixes with refrigerant
- Cooling becomes weak
- Ice builds up on coils
- Compressor works harder
- Gas leaks occur faster
This single step—often ignored by cheap installers—can ruin your aircond in less than a year.
3. Incorrect Piping Slope Causes Water Dripping and Mould
Water leaking from the indoor unit is one of the most common issues caused by poor installation.
Why it happens:
- Drain hose isn’t angled properly
- Water flow is obstructed
- Hose is bent or too short
- Piping isn’t secured tightly
- Dust builds up and clogs drainage
Improper drainage leads to:
- Water dripping onto walls or furniture
- Mould growth around the aircond
- Bad smells
- Ceiling stains
A good installer ensures the drainage is smooth, angled correctly, and tested before leaving.
4. Wrong Indoor Unit Placement Weakens Airflow
Where your indoor unit is placed affects how well your room cools.
Poor installers choose locations just to make their work easier, not to maximize airflow.
Bad placement leads to:
- Uneven cooling
- Hot spots in the room
- Higher energy usage
- Slow cooling
- Constant temperature fluctuations
Proper installers like JBCoolCare consider:
- Airflow direction
- Sunlight exposure
- Wall strength
- Piping efficiency
- Aesthetic placement
- Avoiding structural beams
A smart placement can reduce your electricity bill by up to 20%.
5. Loose Brackets and Poor Mounting Can Damage Walls
When the indoor or outdoor unit isn’t mounted properly:
- The unit vibrates
- Noise becomes louder
- Screws loosen over time
- The plaster wall cracks
- The whole unit may fall
For outdoor units, this is especially dangerous.
A falling compressor can cause serious injury and property damage.
Professional installers use:
- Leveling tools
- Heavy-duty brackets
- Accurate drilling
- High-strength wall anchors
Safety is not something you want to compromise on.
6. Using Cheap, Thin Copper Pipes Shortens Aircond Lifespan
Some installers use low-grade or thin copper pipes to cut costs. These pipes:
- Leak faster
- Don’t handle high pressure
- Corrode easily
- Reduce cooling efficiency
A quality installation should always include Grade-A copper piping with proper insulation.
JBCoolCare uses only premium materials to ensure long-term performance.
7. Poor Electrical Work Can Cause Short Circuits
Airconds draw a significant amount of electricity.
If installed poorly:
- Wires may overheat
- Power may trip frequently
- The aircond may fail suddenly
- Electrical fires can occur
Suruhanjaya Tenaga (ST) requires that wiring work be done by certified technicians.
A professional installation ensures your aircond has:
- Correct cable size
- Proper grounding
- Safe power connection
- Stable voltage supply
This protects both your home and your aircond.
8. Poor Outdoor Unit Placement Reduces Cooling Efficiency
The outdoor unit needs proper ventilation and space to release heat.
Bad installation includes:
- Placing the compressor in a cramped spot
- Exposing it to direct sunlight
- Mounting it near exhaust vents
- Installing too close to walls
This causes:
- High energy usage
- Overheating
- Faster compressor wear
- Reduced cooling power
A professional installer chooses the most optimal, safe, and cooling-efficient location.
9. Cheap Installation = Higher Long-Term Costs
Many homeowners choose the cheapest installer, only to realize later they must pay for:
- Gas refills
- Part replacements
- Bracket changes
- Drain pipe repairs
- Rewiring
- Leak fixes
In the long run, cheap installation becomes more expensive.
Proper installation saves money by:
- Improving cooling efficiency
- Reducing electricity usage
- Preventing frequent breakdowns
- Extending aircond lifespan
