Recently, after having our S for three years charging on a 40amp plug, we bought and had an HPWC installed. The first question we faced was how to find an electrician in our area. The Tesla site has a handy tool however most electricians were not in our immediate area and I was concerned that if i called someone from closer to Toronto there'd be an additional fee to the pricing since we're a fair distance from the city. Fortunately we had a friend that recommended an electrician he knew that has previously installed chargers and was in our area. We were very happy, with the quick response, the estimate, the price and most importantly the work. So now the question is how to recommend the company\electrician to other owners, or to Tesla for that matter. Is it against forum rules to post the info here? I sent an email to the link off of Tesla's charger installation page however never received a response.
