After an inspection of the boiler, the serviceman, Richard, convinced me to order and install a part for the 5 year old boiler. When I called A B May requesting a technician I said I would wait to get their most experienced boiler technician. I assumed when Richard arrived that he was their most experienced technician. I had called AB May because the former owner of the house had purchased a home " warranty" with AB May. The serviceman advised me that this part would be $1,000 plus and would NOT be covered by the warranty. He said only parts inside the boiler were covered. I agreed to pay for the part and installation $1100, as I thought Richard was in fact their most experienced boiler technician. AB May was paid. The newly installed proved to not work. I was having the very same issues as before. The boiler supervisor, Pat, arrived after several weeks. The boiler supervisor said, and I quote, " This new part was incorrectly installed...it is at an incorrect height so the boiler will not work right and the new part is 'incompatible' with that $900 auto fill device that is here." Now it gets interesting! I asked Pat WHY would AB MAY install a $1,100 part that was 'incompatible' with another expensive part on the boiler and why would their most experienced technician install the new part at the WRONG height...which on boilers is critical?!!? Pat said that they just replaced the part..the way it was..and it would cost me a lot more if I wanted it redone correctly. ( REALLY!) He also said the piping needed to be redone and he sent me a bid for an additional$ 5,000 to make everything' correct'. The boiler is less than six years old... Hmmmmm. What does a 65 year old woman know about boilers? Well, now, quite a bit! FINALLY, at least two months later, A B May agreed to "re-install the part CORRECTLY at no additional cost. I asked, ...what about the incompatibility of the part? If it was incompatible and the wrong part is moved...how does that fix it? I requested them to NOT proceed until their supervisor agreed to replace the incompatible part with the correct part. Their supervisor, Jason, would not agree to replace the part and advised me he was sorry I didn't have the boiler inspected prior to purchase. (I DID have an inspection. Boiler passed. )He stated I was trying to have the boiler replaced at no cost. My response was the same.. No...if A B May orders and installs a $1,100 new part and it is installed incorrectly and...the new part ordered and installed is incompatible with the existing $900 automatic fill valve, A B May should replace the incompatible part with the compatible part. Jason refused. I then asked for a refund and I would find another company to do the repair. Jason said he would talk to someone and get back to me. I advised the waiting serviceman that he was to do no repairs. He got his tools and left. I am still waiting on the approval for a full refund. Jason was short, rude, arrogant, accusatory, hateful and ignorant of the facts. I have absolutely no faith in what anyone at that company says. If I wanted it "correctly installed" I would have to pay more. (I am not kidding!) IF, in addition, I wanted it compatible with the very expensive parts on my boiler...then I would have to pay even more. AND if I wanted the existing professionally installed piping redone which A B May's supervisor says is wrong but never once did the installing technician say the piping was incorrect, that would be $2900 more. I cannot make this up. It is just too unbelievable. Hope you have better luck.
