SUNDANCE Energy Services Inc. came out to do an annual service on the house that hasn't been serviced for a number of years. They came through very quickly and went through everything and explained that I had a fan that was going out that might last a year or might not. I decided to just have a new furnace installed. They installed the new furnaced with two kinds of filters, a hepa filter and electronic filter.
Their work was very clean and fast. I know the job must have been miserable because the job was in the attic. There was no damage at all except nail holes where they had to remove some baseboards but they filled those in for me. They also installed a new thermostat and they took the time explaining how all of that worked both remotely from my phone and physically with the remotes.
I have referred them and will continue to refer them. All four of the folks that I dealt with, from the salesman to the installation crew were terrific to deal with and very professional!
