Giancarlo did a great job with replacing my hot water tank and central air unit. This was a relatively complicated job requiring the replacement of the entire gas venting system to bring it up to code. He was very helpful, knowledgeable, prompt, professional, and definitely cared about providing a good service. He also saved me from almost installing a propane tank that another contractor was going to put in, rather than natural gas. Although a small hick-up extended the project timeline slightly, he did promptly rectify any issues at no additional charge, so overall, the job was well done!
