After having a hard time with a series of event that had already happened I was very stressed and very upset then my furnace went out on top of everything. I called Diamond heating and cooling and they had one of there techs out to my house that evening to fix the problem. The tech was extremely friendly and informative. I was so thankful to have called them. My mind was put at ease and they took a lot of stress out of the whole situation. The savings plan they have is amazing as well. I will be recommending it to everyone :)
