I wish to extend yet again my highest complements to your company for the excellent ongoing high standard of efficiency and positive hands on approach to your customers. More so when it extends beyond the initial installation process and into the realms of small pedantic adjustments, (in my case). I make it a point to raise your companies name in conversations where the subject of heating and cooling comes up. I am grateful for your attention to detail and understanding.
Please accept my grateful thanks for your patience and time in your after sales service, something becoming all most mythical in the 21st century. I apologise for the lateness of this e mail for my most recent installation adjustment which took place last month.
