Safety King was great. The scheduler was very polite and even mentioned a coupon they had for the service as well. My appointment was today 10/8 at 9 am and Rick showed up 20 minutes early. That was refreshing to see someone show up early instead of late for a change. Rick was very knowledgeable and even advised on some more potential problems we might have. I appreciate that level of professionalism. Overall I would recommend this company for any duct cleaning.
