He so honest and compassionate. He asked me a few questions of what is happening. After i had told him. He gave me a few instruction of what to do.

"Professional,prompt and attentive. The previous company installed low quality parts and I continued to have problems. Surefire installed what appears to be good quality parts and my heating system is still working. I would definitely use them again and would also recommend to my family and friends. They are also reliable and prompt. They gave me a window period between 8-10 and they arrived at my house at 10:00. Many companies will have you waiting all day but not Surefire. I want to thank them for a job well-done."

"I called All Weather to give me a quote for replacing my gas boiler. They set up a time for their salesperson to come over and give me a quote. The appointment was only a few days later and a man named Joe showed up on time. He spent some time with me, I told him I was looking for a new boiler and a new hot water heater, but I wanted to see what options I have (since I was debating going to a tankless water heater). He told me going indirect hot water tank is the best option and they always use this brand that's the "best one out there". Even though he may have been right, he didn't tend to my questions or concerns very well. I felt like he was getting annoyed that I had questions and eventually I just let him run the show just to get him out of my house faster. Especially when he gave me a quote of $8600, it was much higher than I was anticipating. One thing I really didn't like was when he said I'd have to get a permit since I live in an incorporated village, which would be an extra $500, meanwhile I already had another plumber tell me a permits only $200. So I went with another company. So even though I can't rate All Weather on their work quality, I didn't get a good feeling from their salesperson."

"I called and happened to get Steve right away and since he was in the area he came right over. He examined the blind to determine if it could be fixed without a replacement piece and since it could he did the repairt quickly and efficiently. He was reasonable and very pleasant."
