G&G Heating came out and performed a Duct cleaning for my home. They were ahead of schedule, which was wonderful! They were very professional and courteous. They made sure to use caution when moving around equipment not to bump any walls or furniture. They were very thorough. I had a question about my bathroom fan and he took the time to open it up and look at it with me and answer questions. He explained the process from the start and made sure I didn't have any questions or concerns before they left. They also did a perfect job of cleanup. They were done in half the time quoted to me. I would definitely use them again!
