Introduction
After a few years of regular use, every air conditioner starts showing some performance changes. If you are using a Dawlance AC, you may notice certain issues after 2–3 years, especially during peak summer seasons in Pakistan.
Most of these problems are normal wear and tear, but ignoring them can lead to expensive repairs later.
Why Dawlance AC Starts Giving Problems After 3 Years
Most units from Dawlance are built for long-term use, but performance naturally declines due to continuous operation, dust buildup, and lack of maintenance. In cities like Lahore, high temperatures and voltage fluctuations also put extra pressure on AC systems.
Over time, gas pressure drops slightly, filters get blocked, and internal parts start wearing out.
Weak Cooling Performance
One of the first signs users notice is reduced cooling. The AC keeps running, but the room does not cool properly.
This usually happens due to low refrigerant gas, dirty filters, or blocked airflow in the outdoor unit. When ignored, the compressor has to work harder, increasing electricity usage and stress on the system.
Gas Leakage Issues
After 2–3 years, small gas leaks can develop in pipes or joints. This leads to weak cooling and longer running time.
You may also notice ice formation on the indoor unit or copper pipes. This is a clear sign that the refrigerant level is low and needs immediate attention.
Water Leakage from Indoor Unit
Water dripping inside the room is another common issue. This usually happens when the drain pipe gets blocked with dust or algae, or when the unit is not properly leveled.
If ignored, it can damage walls and furniture.
Noise and Vibration Problems
With time, AC units may start producing unusual sounds. These can include buzzing, vibrating, or clicking noises.
This is often caused by loose mounting, fan motor wear, or internal parts becoming less stable after years of use.
Compressor Stress and Overheating
The compressor is the most important part of your AC, and it naturally becomes stressed after long usage.
If the condenser is dirty or gas pressure is low, the compressor works harder and may overheat. This reduces efficiency and increases the risk of breakdown.
Sensor and PCB Issues
After a few years, electronic components like sensors and PCB (main control board) can also develop faults.
You may notice random shutdowns, incorrect temperature readings, or error codes appearing on the display. These issues usually require professional repair.
How to Reduce These Problems
Regular maintenance can significantly extend the life of your AC. Cleaning filters every few weeks, servicing the unit once a year, and keeping the outdoor unit dust-free can make a big difference.
Using a voltage stabilizer is also important, especially in areas with unstable electricity supply.
When to Call a Technician
You should call a technician if your AC shows continuous weak cooling, gas leakage signs, repeated noise issues, or frequent shutdowns.
Early repair is always cheaper than replacing major parts like compressor or PCB.
Conclusion
After 3 years, Dawlance AC units may develop common issues like weak cooling, gas leakage, noise, and water dripping. These problems are normal but should not be ignored.
With proper maintenance and timely servicing, your AC can continue performing efficiently for many more years, even in harsh summer conditions.
Weak cooling and water leakage are the most common problems.
Yes, most early-stage problems can be fixed with proper maintenance.
