Chill zone fixed our rooftop unit that wasn’t working. Very professional.

Replaced three rooftop units and had us cold within a few hours. Would highly recommend these guys

Brett and his team responded promptly and took care of our roof top unit project. Would highly recommend

Chillzone was fantastic. I own a facility that needs A/C all the time and when the system failed on the most humid day I was desperate. I had called multiple places with no return calls. The owner not only answered the call but kept his word got someone out right away. thank you

Our office HVAC broke down and I called Brett’s company and he came out in a timely matter to fix the HVAC unit. Very professional and great to work with. Will definitely use them again.

Brett has been a great partner to work with and very knowledgeable in his field. He’s professional, submits quotes in a timely manner, and very honest in his approach. We’ve been in quite a few jams with multiple break downs before, calling other companies and whenever we call Brett he figures out what the main issue is and gets the job done. Highly recommend him for your HVAC needs.

Best Mom and pop air conditioning technician and installers in the business.

Heatwave coming through and our AC broken. They came out the same day, found it was a capacitor switched it out and 15 minutes later the house was cooling off. Great price too.

Tenzing and his associate were very kind, knowledgeable, efficient, and thorough in their work and explanation of the issue. Will absolutely call them again in the future for any air or heating needs!

Had an issue with my Central AC system and was able to get a technician from A's 8 to take a look at our system within 2 days. The gentlemen took the time to do some electrical diagnostics and within 15 min was able to figure out where the open was in the circuit. He proceeded to show me how to change the fuse should the condenser acted up again. Very helpful and would hire again.

Tenzing and his team have helped me multiple times - with regular maintenance, and, more importantly when heat or AC weren't working. They're responsive, diligent, very respectful of being in your home, and they do good work.

I contacted Tenzing at A's 8 HVAC when I had a recent gas fired furnace issue, on the recommendation of a friend. A's 8 were responsive, professional, knowledgeable and efficient. They diagnosed the problem with my furnace and figured out how to correct the problem. They also explained to me what was happening and took the time to cover their work shoes with booties in my apartment. I'll definitely use A's 8 again and would highly recommend them.

Excellent HVAC service company. Highly recommend.

I’ve had a fabulous experiences working with Tenzing and his crew. We recently completed a complicated air source heat pump multi zone system in Brookline for one of Boston’s leading architects and As8 did a fabulous job. Great attention to detail for small residential projects but are capable of handling large complicated commercial jobs as well. On time, never had a cost overrun. I recommend them highly

I’ve used this company a few times now. Most recently, this weekend in the middle of the brutally cold temps our system stopped working. They came out to assess, made sure we were safe, and worked with us to order and install a new heating system. Tenzing was great answering all of our questions and is very professional and responsive. In the spring we plan to add central AC to our system and will be using A’s 8 again. I highly recommend them.
