I contacted Vegas Valley Air late Tuesday evening and Eric replied immediately. I told him my fireplace wouldn't light, and I asked when he could fit me in to check it. He was able to fit me in Thursday and kept me updated with his arrival time. He wore booties to protect my floors, which I thought was extremely professional. He quickly found the problem, fixed it and ran safety check and diagnostics on my fireplace to make sure it was working properly and making sure it wasn't leaking any carbon monoxide. He did a fantastic job! I will definitely use Vegas Valley Air again!
