Requested service to replace two water heaters. The new heaters were furnished by myself - in place and the old ones were removed from the attic. All the hard work was done. All that remained was to simply connect the water and gas lines. The quote was $1,700! I sort of thought there would be less of a fee given the situation but it seemed this did not fit into the pre-defined category and there was no way they could budge on the price. I’m quite sure Abacus would do a great job and stand behind their work but in this case I will never know? in the end I went with another well known competitor and surely similar to Abacus would not warranty any client furnished parts but labor only. Nothing bad to say about Abacus as a whole but depending upon your needs (or disposable cash) shop around to find someone willing to work with your situation
