I have two heaters in my home, one upstairs, and one downstairs. The one upstairs was not working, so I called Barrus Heating and Air. A few days later he came out to fix it. It only took him about an hour to take care of the problem, if it even took that long. They are always quick to respond whenever I need them, and I know that if it was an emergency, they would've been out faster, but since I have another heater, I didn't need to worry about waiting. That is why I have been using them for 7 years now, and it's why I will continue to use them.
