Best Tank Type Water Heaters in San Antonio TX

I have a tankless water heater that was frequently, although inconsistently giving an error code. I had Chambliss come out to investigate the cause. The first plumber spent about an hour, but could not replicate the problem. A more experienced plumber was scheduled for several days later. He spent about 2 hours, but again could not replicate the problem or find an issue. Towards the end of the service call, I suggested the the look at the vents on the side of the house because the manufacturer said that venting could be one of the issues causing the error code. He looked at the exhaust pipe and found and removed a couple of wasp nests. However, he did not take of the cover to look at the intake pipe. After he left, I took off the cover and found the intake was blocked with a bird next and several large wasp nests. I called the tech and he came out and removed the debris, spending another two hours onsite.My frustration is not with the effort the plumbers gave, but rather with the fact that I had to find the probable cause of the issue by doing something I believe the plumber should have done in the first place.I received the invoices for the two service calls and the cost seems a little excessive, especially given the fact that I was the one who found the problem. I have not had a chance to discuss the bill with the company, but will do so in the next couple of days.I have previously used Chambliss (ironically with the installation of the same water heater) and was quite happy with their services and costs,

Great service and fast. He was there on time and very friendly. The only thing is that it was expensive to just run a line through. But at least I didn't have to do it myself. Which I would have done but this saved me time. Thank you
