Stealth Control Systems

Stealth Control Systems is an HVAC and electrical contractor based at 69 Tenean St in Dorchester, run by owner Howard Sanford. It has been an LLC since July 2019 — seven years — and also trades as Stealth Controls and Sanford Controls, LLC, with the website carrying the name Stealth Energy Controls LLC. The work spans residential and commercial heating and cooling: air-conditioning repair, installation and replacement, heat pumps, mini splits, forced hot air and hydronic systems, plus commercial rooftop units and refrigeration. The company also does electrical installation and upgrades, germicidal UV air-quality work, and smart-home automation and PLC integration. It advertises 24/7 response, says its technicians are licensed and insured, and offers labour warranties and maintenance plans. Its stated coverage is Boston and the area south of the city. Recent customers are emphatic. A homeowner writing in April 2026 described upgrading to a tankless combined heating and hot water system and praised the speed, price and clean-up. Another that month had a Gree heat pump system with Ecobee Premium thermostats and sensors installed in a condominium and highlighted punctual arrival and advice that improved heating efficiency beyond just fitting the hardware. A May 2026 reviewer singled out Howard for staying calm through last-minute Mass Save paperwork demands and getting every document filed on time. Google shows a 5-star average from ten ratings. Two things temper that. All seven written reviews on file landed inside a two-week window between 21 April and 4 May 2026, which is a narrow slice of a seven-year business rather than a steady record, so ask for references from jobs outside that period. And there is one substantive complaint that predates them: in November 2023 a commenter on r/boston wrote that they regretted letting the company install their central air conditioning, that the install did not go well, that after-install service was nonexistent, and that an issue reported in the spring took until well into the summer to repair, with different excuses on each phone call. Nothing in the record shows how that was resolved. Worth clarifying too: the Better Business Bureau lists the business with a single employee, while several reviewers describe a team and staff arriving on site. The BBB gives an A+ letter grade, but the same profile records that the company is not accredited and publishes no reviews or complaint count of its own, so that grade is not a customer-satisfaction measure. Stealth suits a Boston or South Shore homeowner doing a heat pump, mini split or tankless conversion, particularly one navigating Mass Save rebates, where reviewers say Howard is strong. Ask directly about who performs the work, what the post-installation service commitment is, and how a callback is handled — that is where the one detailed complaint sits.
