We have been with the company for 2 years. Last year my water tank was maintained and the technician was very helpful and knowledgeable BUT did not identify any additional issues on this 14 year old tank.
This year, the pipes started making a loud grinding noise each time we turn on the heat or hot water.
Raul came in, flushed the unit and noticed 2 taps that leaked water, which on a 15 year old tank should be expected. He was very pleasant, professional and knowledgeable but unfortunately could not identify the noise issue 100%. The next day, him and Aaron came to do additional testing (no extra fee!) and Aaron pointed out the dip tube issue in 5 min. He is a water heating encyclopedia! We were very impressed with the level of his service and professionalism. Our old water tank/heater is on its last legs and should be replaced ASAP.
I wish that Raul had been able to identify the dip tube problem the first time so we would not have to spend money on flushing the broken unit ($149) and new parts ($249+) which will need to be thrown out when the new unit goes in very soon...
The quote we received on a Tankless unit is costly, but I have no doubt that if we choose to hire Aaron and Raul, they will do an amazing job.
The only reason i am giving less than 10 is because of extra money we have to spend for the first visit, as outlined above. Otherwise, the service (call centre, technicians etc) from Accuserv is an 11/10.
