$286 vs. $150 at another company. Here's the facts about YES.
My pilot light wasn't staying lit. After doing some research online and seeing visible corrosion on my thermocouple, it was safe to say this needed to be replaced in order to keep the pilot on. I went to the store and picked one up for $13 just to have one ready.
Scheduled with YES to have someone come out between 6-8pm. Was told technician would be a few hours late. Arrived at my house at 11pm. He was friendly and professional.
Upon looking at my water heater the technician told me I should replace the gas thermostat because it was probably going bad. Also, replace the entire Pilot And Igniter Assembly. Also the co2 vent needed to be slid into place an the anode rod needed to be replaced. For all this work, it was better to install a new unit (quoted $1200).
After his quote, I asked the technician if the pilot light wasn't staying on because of the corroded $13 thermocouple that I had researched online. (9x out of 10 this is why a pilot light won't stay lit) at first he told me it couldn't be replaced on its own, the entire burner assembly needed to be replaced. Plus, he didn't have a replacement thermocouple with him. This is the point when I told him it could be replaced on its own and I already purchased one. He then agreed it could be replaced independent of the entire burner assembly and said "$286 is the price in the book". I declined and was charged $29 for the recommendations and estimate.
I ended up calling "Pure Plumbing" at 7am and they were at my house by 8am for a free evaluation and estimate. Replaced my thermocouple for $150 (parts and labor) and my water heater is back up and running.
