Cosmopolitan Mechanical's service was basically good. They came and quoted a Rheen HE furnace to qualify for my rebate. It was a decent price--actually, a very competitive price. We were concerned about replacing our old furnace because it was working so well and so quietly but it was over 30y/o so it was time, especially with the rebate program.
CM replaced our furnace and added additional gas piping for future conversion of our electric water heater to gas.
CM was quick at installation and could meet any schedule.
I previously thought they didn't fall through on the little extras that were promised but apparently, that's just an issue my partner has with communication. CM has followed through on every single detail and promise. So sorry for the confusion!
