As it has been mentioned by customer, installation was done on 17/Nov/2009 for a Viessmann Boiler and a Noritz tankless unit.
We did a number of service calls for customer since installation as below:

Tankless WH. not working / called Noritz / problem with clogged burners / problem with dirty spark maker, dirty sensor, dirty ventor motor, dirty heat exchanger / heat exchanger needs descaling for one hour / opened up all and vaccumed and cleaned / descaled with the special liquid == $497.20 incl. tax.

****Technician went to fix the customer's tankless WH-it showed code # 90----called Noritz----Noritz company said they need an air compressor to clean the dust ,…..this happens in areas where there is too much dust.== No Charge.

As stated above total service calls attended for Noritz tankless unit total to 4 since 06/Nov/2009, the two recent calls 14 & 22 were at no charge to customer.The other two services that were carried out on above mentioned tankless unit were carried out in 2011 & 2013.
However, we also, as mentioned above carried out three other service calls on Visseman boiler, two of which were at not charge to customer only the service which was carried out on 18/Feb/2014 was charged at $169.50 .
Another point to note is the fact that all gas piping is done according to code and piping from meter including branches are based on BTU requirements.
Also as mentioned by customer problem was solved by an electrical repair done by her brother, and it was not related to gas piping but as Gas technicians we are very limited to the amount of work that we are permitted to do on electrical aspect of the job.
Nevertheless, we regret that Anita had to go through this experience, we try our best to provide the best service that we can to each and every one of our customers, we have tried to solve the problem with all our best intentions, have made number of calls to Noritz technical support.
We sincerely hope that Anita would have many years of problem free operation with her boiler and tankless. We would always be available for future services.
