Safety King was extraordinarily professional from the beginning all the way through to the end. First, they called the day before to remind me of my appointment, and told me the technician would be coming to my house between noon and 2 pm. Then, when I asked her if there was any way he could come a little earlier, she said, “I can’t guarantee anything, but I’ll certainly ask him.” The next day, around 10:30 am, the same woman called me and said, “OK, the technician could be at your house within a half hour. Do you still want him to come earlier?” Sure enough, Eric was at my house by 11 am. He only needed me for about 5 minutes to walk him through the house and show him where the vents were and where the furnace was. From there on, he pretty much did everything by himself within about 3 hours, including cleaning the air ducts AND our horribly disgusting dryer vent (filled with about the equivalent of a tall kitchen garbage bag full of lint!!!). At the end, he cleaned up any mess left behind, including the lint that got onto our driveway from the dryer vent. He showed me photos of the ducts and dryer vent duct before and after, and I was astonished at how much stuff he cleaned out…especially from the dryer vent. He then showed me a menu of additional services offered by Safety King in case I was interested in any extras, but he said he didn’t really think my house needed them. An honest technician? Remarkable. This company clearly knows what they’re doing, both technically and with respect to customer service. They even reduced my cost by about $60 when he realized that my dryer vent came out on the ground floor (even though the dryer is on the second floor). They charge more if they need a ladder to reach the dryer vent, but when he saw he didn’t need the ladder, he reduced the bill. If he had left the charge the same, I probably would not have figured it out, and I think Eric knew that. But he’s obviously an honest guy and did the right thing by subtracting the $60. I would use them again in a heartbeat. High quality, honest, expedient service. You definitely get what you pay for!!
