They got it done, and it works!
Korrect Plumbing, Heating, and Air Conditioning came because we have one of those heating systems that's a boiler and floor heater. It had been making a lot of noises under the floor and in the boiler part, then it stopped work completely. When Korrect came, they not only got it working, but also got it to be quiet.
They came when they said they would, which we really appreciated. They didn't have the right part on the first day, but came back the very next day to get it done. They got it done right. I could tell they knew what they were doing.
