I just had Convertible install a tankless water heater and a new Air Conditioning unit at my home. The company is top notch from start to finish. I called on a Sunday afternoon and had instant response from Chris, the owner, and he dispatched a tech to look my AC unit on Monday. Tech did very thorough inspection and found the problem and explained it well - needed to be replaced. I replaced the AC unit and decided to update my 10+ yr old water tank with a tankless unit. Chris came to house to do estimating and pointed out an (serious) error on AC from original installation. He was super patient with as he answered a lot of my questions even on the weekend. Lastly, the installation tech, Kumil, was fantastic and I could tell was professional by taking time to do a proper job (not rushing) and also correcting a few poor choices from original install. My heating system is a non-standard, high velocity system and Convertible was very familiar with them. Great company with integrity. Would strongly recommend.
