My heat went out 2 weeks ago and the guy tried to tell me that my pressure relief valve needed to be replaced which was option 1 and cost $1200 option 2 was replacing the pressure valve and expansion tank which was $2,600 and the third option was to replace the boiler all together which was $14k - that is more than quotes I have received in the past to install an HVAC unit. I did not use them but it turns out the pilot light went out which I ended up lighting and fixing on my own saving myself and the guy didn't even look at it or say anything about the pilot light being out which should've been the first thing he checked if they were honest plumbers . Do not use these people
