I am very disapointed with this company!!!! Water heater sensor "tripped" and wouldn't allow the water heater to run. We called them and they fixed it with cleaning out the filter and some compressed air. We were charged $115 for this... Water heater sensor tripped the water heater again 2 days later, this time I did exactly what the technician did and it worked again for another 2 days. Then it tripped again so I figured something was wrong. The technician came back 5 days later and said that a cord was bad and would need to change out the cord. He said that he would only charge us for 1 hour of labor. The technician then used our bathroom twice, took at least 4 phone calls, and left our house twice to get different parts or something... He ended up telling us that if we paid right now then he would only charge us for 2 hors time, and I said no I don't think that is right, so he said well fine if you don't pay now then I will charge you for 3 hours of labor!!!! What kind of company is this?? They apparently don't stand behind their services... We are now going to end up paying them $1035 for a new power cable more or less!!!! Shame on you Superior!!!! I also forgot to add that when I went downstairs to check on how he was doing, he was telling me that he was getting ready to cut some other cords and replace them because he couldn't get it to work... So I suggested that maybe the water was already hot... Sure enough it was working fine, so I don't know how long he was down there trying to figure that out. Also the warranty on their billing statement says that the labor and service is warrantied for 90 days... This is clearly not the case read more
