Thank you the response to me asking for help to restart the Aga. Very efficient and helpful. Helen was both (office staff).
Kyle is professional, capable and knows his stuff. I am therefore very happy with Kyle and his work ethic and am overall very satisfied. In fact, in future, I will actually ask for him by name as my preferred engineer to come out. He is a credit to Merretts Heating and did the tasks admirably well. Its always good to achieve a positive result and a satisfied customer. Kyle engendered a high level of trust with a final good, satisfaction rating.
Mr B has praised Callum for his visit to him to drain down and replace the zone valve on and Kyle for the service done.
I would like to formally record my thanks and congratulation to Merretts engineers on completion of their work at our house. The job was to remove the old heating system, based on the original installed when the house was built in 1950, and install a state of the art system. Their approach throughout was exemplary. They minimised the disturbance to us personally and to the structure of the house. This was no mean feat in itself considering the age of the old system . On the installation they showed great skill in running the new pipe work to minimise the exposure and affect on appearance It was a pleasure to have, often, four engineers around the property who were so accommodating and helpful They are a credit to Merretts in all senses Thank you for a job well done. I can thoroughly recommend your work.
