Blackwell Energy Corporation is a Hanover company that, by its website's account, delivers propane and home heating oil and installs and services ductless mini-splits for homes and businesses on the South Shore. A 2025 Google reviewer who needed a generator said the company called right back and installed it on the day it said it would. A 2025 customer thanked the company for a new stove and wrote that it took a few months. That 2025 reviewer said the people who came walked them through each switch on the stove and helped clean the dirt behind the old one, and that one of them stayed to make sure everything worked. A 2025 reviewer wrote that every time they called, the company was attentive and listened, and recommended it for oil deliveries. A 2025 reviewer described a good experience with propane delivery. The website lists Hanover, Abington, Braintree, Brockton, Duxbury and other nearby towns in its service area and describes the business as family- and veteran-owned. It gives two founding years: 2019 on the homepage and 2009 on an About-page panel. On Google the company holds 3.7 stars from 15 ratings.
Thank you for my new stove. It took a few months. So happy the guys that came was so nice. Walked me through each switch on the stove. Helped me clean the gross dirt behind the old stove. He went beyond his work job. Stayed with me to make sure everything work. I would give 100 stars thank you
