Highlights
- Steady 4.7 rating — corroborated across Google and independent directories
- Same-day response — multiple reviewers cite fast turnaround on repairs
- Thin recent activity — only one Google review in the past six months
A steady 4.7-star rating and reviewers who keep mentioning same-day arrivals are the headline for A'S 8 (AS8 Corporation), a Medford HVAC contractor built around heating, cooling, ductless mini-splits, and water heater work. The company's own site describes itself as a Massachusetts-registered mechanical service handling installation, repair, and replacement for residential systems. That 4.7-from-14 rating isn't just self-reported — it shows up again on several independent directory listings that aren't run by the company itself. Reviewers over the past several years describe a mix of full system installs and repair calls, and one detail keeps repeating across multiple write-ups: same-day arrivals when something breaks down. The most recent review, posted this spring, is short but positive, and nothing negative turns up anywhere else in what's out there. Recent activity is light, though — just one review has landed in the past six months — so there's less to go on for how the company is performing right now compared with its earlier years. For a Medford-area homeowner with a heating or cooling repair, this reads as a small shop with a consistent rating and a habit of showing up fast; given how thin the recent reviews are, it's worth confirming they can still turn things around quickly before counting on it.

Tenzing & his crew are the best - everyone he works with is incredibly polite and always goes the extra mile with everything they do. They installed 2 new HVAC systems and a whole house dehumidifier during a major renovation. Highly recommend! Very dependable and quick to reply to any texts.

I cannot imagine a more dependable, honest, and professional HVAC company. Our a/c unit broke in the middle of a heat wave. Tenzing assessed the entire situation and communicated back and forth with the a/c company to make sure that he was choosing the proper system to match the duct work in our house and so that everything would go smoothly when they installed the unit. When Tenzing or his team say they will arrive at a certain time, you can be sure they will arrive AT that time. The installation took 10 hours. They ran into a technical issue and tried to trouble shoot, but the a/c manufacturer was already closed for the day. So they came back to complete the job the next day. The next morning we discovered we did not have hot water. They had to turn the switch to the boiler off to finish the installation. We didn't realize that, called Tenzing, and his technicians were at our house within a half hour to point out the simple problem and turn the switch back on. Honestly, the most patient, polite, and professional people I have ever worked with.

Installed ductless a/c with heat pump and a dehumidifier in the basement. Tenzing came up with a good design and solutions and kindly squeezed us in between bigger jobs so we didn't have to wait. His guys really know what they are doing and work their butts off. Top notch expertise and professionalism. And they do NOT price gouge like other HVAC companies. The best.

I've been meaning to write a review for a year now, Tenzing and his team at AS8 completely renovated our existing heating system last year in June 2023. We went from radiators and no AC, to 2 heat pump systems with central air and heating. The fabulous team worked hard on site for approximately 2 weeks to coordinate removal of old radiators, and install a new duct system on two floors of our home. We now have an amazing system in place and filtered air for heat and cooling. The team was incredibly thoughtful and diligent. The system has been working without trouble for a year now. If anything changes I won't hesitate to call them up!
