I called to get an estimate, and was just blown away. When I phoned in for an estimate, I was asked when I wanted a unit installed.I explained that the Water Heater was already goon, and drained. They had someone at my home within three hours with a new ater heater. They installed it, and also asked me if he shoul put Pooties on to cover his shoes. My Garage Floor is filthy. I laughed and told him no. He disconnected the old one, removed it, and had the new one in really quick. I watched him as he put it in, and he did everything right. He also explained some things to me regarding care and maintenence of the new unit. He was quick to take theo old one with him... Thank God! Villy was my installer, and He was absoltely amazing. When he left, he looked as clean as when he arrived. He cleaned up everything prior to leaving, and made sure to ask f that was all I needed. He said I could call the company and add anything while he was still there. Everything was great. I managed to get a Top of the line unit with a Power Vent, Installation, Same Day.... cheaper than anywhere else with a greaat Warranty. I would definitely use Delta Mechanical again. I am c=going to shedule some more work from them very soon. I would recommend them to anyone that needs work done. I would also like to give a Shout Out to Villy. He was the installer. So Professional, cutomer service oriented, clean and neat, represented his company well, and I only wish I could have found employees of this calibur when I had my business. Villy was AWSOME!!! Thank you to him as well! I will see you all very soon!!!!
