After calling several furnace companies, Knight Plumbing was the only one who was able to get to my house quickly at midnight for an emergency call, my furnace quit working. It was determined a new furnace & hot water tank were needed. My son, daughter-in-law & 2 grandkids (ages 5 & 2) live with me. Knight Plumbing was able to install the furnace AND hot water tank one day later. Geoff was very patient & courteous answering all my questions & giving all options available to me. Steve who did the install, was prompt, courteous & efficient. Customer service all around (including Tina in the office) was top notch! Knight Plumbing has my business for life!
