"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"We've used this service twice - both time to install split level units. We couldn't be more pleased with the quality of service and the technician. Steve was on time (a rearity for contractors), the job was completed in a timely manner, he clean up after himself and best of all the units work like a charm. Unlike most contractors that grab the money and disappear Steve has checked in with us to confirm that the units are still working. Excellent customer service indeed!"

"Ray was friendly and very professional and you can tell immediately that he was very customer oriented. As far as prices go, he was more than fair compared to the other bids. As a matter of fact I expanded the scope of his work to include a new water heater too. All the equipment supplied was 100% new, still in the factory cartons and the installation work was TOP QUALITY. Ray not only sold me the job but he did the installation too. He and partner Ken, and their assistant (3 man crew total) worked very professionally and effectively. Needless to say I HIGHLY RECOMMEND THEM."

"Jim listened to my issues to get a full understanding of problems. He was very reassuring. He tried to fix the issue as cost effectively as possible. He took the time to explain the problem, and what he would recommend to fix the problem. I was very satisfied with the results. The price for the fix was fair, I've already talked with him about having some electrical work done in the future."
