A clear and concise subject line is crucial. It should summarize your issue in a few words. For example, “Complaint Regarding Malfunctioning AC Model XYZ123.”

Step 3: Introduce Yourself and the Purpose of the Letter

Begin your letter by introducing yourself and stating the purpose. Keep it straightforward, like: “I am writing to express my dissatisfaction with the performance of my air conditioner, purchased on [Date].”

Step 4: Describe the Problem in Detail

This is where you need to be specific. Describe the problem you are experiencing with your air conditioner. Include details like when the problem started, how it affects your daily life, and any steps you’ve already taken to resolve it.

Real-Life Example:

“In July, amidst a heatwave, my AC unit started emitting a loud noise followed by a complete shutdown. Despite resetting the system, the issue persists, making the living conditions in my home unbearable.”

Step 5: State Your Expectations Clearly

Be clear about what you expect as a resolution. Whether it’s a repair, replacement, refund, or service appointment, state it explicitly.

Step 6: Attach Supporting Documents

Attach any relevant documents like the purchase receipt, warranty card, previous correspondence, or service reports. These documents can provide a clear context to your complaint.

Step 7: Be Professional and Courteous

Always maintain a professional and courteous tone throughout the letter. Avoid aggressive or accusatory language, as it can be counterproductive.
