"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."

"After contracting the installation, the company performed 2 walkthroughs to determine the BEST way to complete the installation. They determine the installation would take two days. The installation crew arrived early on both days. The installers and their work were neat and clean. They cleaned up after the installation, including vacuuming in the house. Dave, the chief installer, treated our house as if it was his. The equipment works as advertised. We could not be more satisfied with the work. From the first meeting to the last equipment check, VERY professional. The pictures show the compressor installed on the roof attached to the chimney, and the main inside unit installed between two windows."

"For years I have wanted to update my very old and inefficient American Standard cast iron boiler. I was very fortunate to find Mr Joe Burriesci the owner of Mayjac Plumbing who took the time to evaluate the best options, since the old boiler handled two apartments. We collectively decided to go with two Navien Combi Condensing Boilers, but the best part of the entire process was how meticulous the installation was done. From start to finish Mayjac Plumbing kept every promise and timeline made. I highly recommend Mayjac Plumbing..."

"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."
