The service man (owner) showed up promptly as promised. A new tankless boiler is professionally installed, including the clean up job, to my extreme satisfaction. He uses quality parts. The warranty is detailly provided in the following days. The follow up procedure is in placed to ensure that the Government rebate application is to be granted. By the way, I particularly enjoy the part that, as the job was complete, the service man (owner) wrote an online career upgrading exam with my consent. I sincerely endorse his professionalism and quality work and I will strongly recommend him to anyone.
