After initially seeking quotes on a weekend, I was impressed to be contacted by 2 of the 3 suggested installers on the Monday. The 3rd installer only contacted me some time later, after I advised you. All 3 quoted similar prices, albeit on widely varying equipment. I decided to accept Accord because of their willingness to answer questions, consider and discuss equipment and installation options, conduct a second visit to discuss installation and they are a well-established local general electrical contractor. Since installation, they’ve been very responsive to queries to explain and clarify matters. It’s only early days to evaluate the effectiveness of the system but the data seems pretty good so far.
