Green Collar

My thanks to the crew from Green Collar for their work on my house June 2025. Nick, Tyler, Clint, Brandon and others worked hard insulating and helping make my home more energy efficient. They provided thoughtful evaluation of what was needed, and excellent communication about adjustments to the work plan. Good clean up and really nice folk to have working here. Cheers

Todd and Derrick did an amazing job installing my mini split system. They arrived on time and we're very professional and were very careful in and out of the house and cleaned up afterwards. I am very impressed with the small amount of exterior piping on the house. They really take their time to make sure everything is done right and LOOKS GOOD! They explained very well how to use the equipment and told me if I have any questions afterwards don't hesitate to ask. Also Wes did a good job with the initial consultation of trying to figure out the best possible way the system should be installed. I highly recommend Green Collar if you are thinking about getting a mini split system.

Juan, Ricky, Johnathan and Jake all did an awesome job today at my new house making it more efficient for us. They were very polite and had lots of knowledge. They worked as a team and were very caring individuals, liking their job!

I had Green Collar do 3 days weatherization work at my house, in a MassSave contract. Everything went totally smoothly, the crew, capably led by Nick, was skilled, friendly, team-like, professional. They solved unexpected issues, and pivoted as needed, very well. I was expecting to deal with a stressful situation, and went so well. Also kudos to Rise Engineering, working within the MassSave system; and how they and Green Collar collaborate effectively. Many thanks!

Had some heat pumps installed by Todd, Brent, and Derrick. They showed up on time, finished on time, and did a good job. Very polite and friendly and answered all my questions. I would recommend them to anyone!

Are you looking to get MassSave work done? Take my advice and wait as along as it takes to work with Green Collar. They are talented, detail oriented, and kind. Nick, Codie, Lee, Juan, Lincoln and Jonathan did an amazing job completing tedious work. They are all-stars! Aleta in finance made everything clear about payment and helped me finish everything up once the job was over.
Whoever MassSave recommends I would politely cancel and switch to Green Collar!

Rick and his team were stellar at getting my insulation done in a quick and efficient manner. Daniel with his follow up and persistence in helping navigate through the Mass Save process was excellent and the office staff were very friendly, professional and responsive...highly recommend!!

A big thank you to Jeff, Nick, Erin, Wallace, Brian and Tyler. They worked for 3 days crawling around my attic and in areas inside of my knee walls sealing up air leaks and installing insulation. They had everything covered with plastic sheeting in order to minimize dust. They also installed insulation to my exterior walls. To do this they removed a strip of my vinyl siding in order to inject the insulation. I was very pleased that when they were done, the exterior siding looked perfect. While here they also discovered that 3 areas enclosed by knee walls had no ventilation. They were able to install gable and roof vents to solve this problem. All looks good. Looking forward to a tighter house! Thanks again.

THANK YOU ALL!!! FOR THE PROFESSIONAL JOB..ALL WERE POLITE..ON TIME..KNOWLEDGEABLE OF THE JOB...THOUGHTFUL OF THE HOME OWNERS PROPERTY..10 OUT OF 10

Jeff, Nick, Wallace, Erin and Tyler took care of weatherizing my home today. They replaced insulation, did part of my basement, did some testing and more, they were THE nicest crew I have seen in a very long time. They were so polite and thoroughly described what they were doing. It’s rare to see an entire crew be that kind and awesome. But I honestly can’t say enough!!!

We recently had Todd Derrick and Brent install some mini splits. They were very respectful, timely, and professional. They cleaned up as they went and even made sure to clean up any dirt tracked in from their shoes. They made sure to ask if we had any questions along the way and showed us how to use the mini splits before leaving. We are very happy with the work that was done and highly recommend Green Collar!

Thanks to Todd, Brent and Derrick at Green Collar, I have a new mini-split system, installed in 6 hours today. They were congenial, conscientious, efficient and easy to be around as they worked both inside and out.
The system was explained, all my questions were answered
and the house is in good shape.
Very grateful.
3 weeks later. They just installed a new hot water heater. Wow!! Once again-- friendly, good - natured and easy to work with.
More appreciation for this good work.

Thank You Green Collar for the great job you have done on installation of the new heat pump for my house. Quality work, friendly, ethical, and hard working team!

The team was very professional. When I had an issue they came out right away. I would highly recommend GREEN COLLAR

Todd, Brent and Derrick were awesome when they came to do our mini splits. Super nice and explained everything great. Answered all the questions we had and made sure everything was perfect before they left. Great service and great communication from the company on when and how they would do things.

I would highly recommend Green Collar for mini split installation. The whole process was extremely easy, from getting a quote to the installation itself. Communication was quick and helpful. Todd Brent and Derrick did an exceptional job, kept the house incredibly clean, were very considerate and fast. We love our new mini splits!

Todd Brent & Derrick installed a new mini-split system in my home yesterday when it was 0 degrees outside. They worked tirelessly all day to get the system up and running for me and did a great job. After almost 9 yrs of failing heat in the winter I finally have a system that works properly.

Todd, Brent, and Derrick did an amazing job installing our new mini splits and getting rid of our massive, outdated electric heaters. Those heaters were such an eyesore and crazy heavy, but they handled everything so smoothly. They were friendly, respectful, and really easy to work with. Todd even went above and beyond by patching up the wall after cutting into it, which they didn’t have to do. We did a ton of research and got multiple quotes, but Green Collar was by far the most reasonable and didn’t try to upsell us with unnecessary extras. Highly recommend!

I recently had Todd, Brent and Darrick out to install mini splits in my home. They were very professional, timely and efficient. I absolutely love the work they did. They informed me every step of the way and let me ask as many questions as I needed. I would recommend 10/10!!! Seriously great job

The crew — Todd, Brent, Derrick and Wes — did an outstanding job installing our mini splits. The work, both inside the home and out, was completed in a timely and professional manner. The work areas were cleaned up as they went, and the waste taken away with them.

There was a slight scheduling mix up at the outset, but the crew put forth max effort and met the original timeline to complete the project, despite the tighter timeframe.

Very satisfied with the workmanship and professionalism.

Just completed insulation and sealing work through the Mass Save program with Green Collar. Jeff L., Brandon D., Lincoln E. and PJ were on time, professional, skilled and courteous. Highly recommend them!

As a project manager I have dealt with a lot contractors and I have to say that Green Collar did an amazing job installing my heat pump system. From scheduling to the installation crews, it was a great experience all around. Special shot out to the crew on site Wes, Todd, Brent and Derrick. They were neat, polite and very professional.

We had an amazing team from Green Collar come in and put in insulation into our attic at our home. This team was amazing !! They worked so well together. Extremely courteous and professional and we just can't say enough about this team. I highly recommend them and if we ever need any work done on our home, this will be our #1call. Excellent service !!

Jeremiah, Jordan, Mike and Cameron did a great job for us today (12/9/24) These guys were very professional, friendly, and respectful of the property. They did excellent work. Would highly recommend!

Todd and Derrick came out to install my minisplits and were extremely professional and helpful with all the information I need to run them efficiently.
Also left his number to text with any questions moving forward.
Top notch extremely satisfied experience!
Thanks Todd, Derrick and Green Colar!

We just recently had Todd, Derrick, and Brent out to complete the installation of our mini splits. They were neat and professional. They answered any questions we had and were very informative about the system and how it works. Once the installation was complete, Todd did great at explaining hot to operate the system efficiently, as well as how to keep up with regular maintenance. Very satisfied with our experience!

Todd and Brent did an excellent job on my monopolist install. Very professional and answered all my questions. You are lucky to have them representing Green Collat!

Very awesome and professional service and was done quick I recommend to call these guy when you need have hvac service done call them

I just had a full installation of mini-splits done. Todd and Derrick did an amazing job. They cleaned up after themselves and kept me informed of the process.

They were awesome. I had Todd and Derrick and they worked fast and had great communication. Definitely recommended these two.

Jeremiah and his crew just finished up a two day insulation and sealing job at my home. Jeremiah and his crew were professional, treated my home with care and left very light footprints. They took extra care in handling some complex pieces of my home and I watched them do thorough, careful work. Highly recommend Green Collar and their team.

Green Collar was great to work with on our mini split install! They were awesome about following up and shepherding the complicated process with MassSave through to the end. All of their staff and subs were nice, respectful, and helpful.

Green collar of South Hadley installed mini split heating and cooling in my home today, Their employees, Todd, and, Derrick we’re punctual, Courteous sufficient they did a great job with the install.

Jeremiah and his crew were fabulous. They listened to my concerns, accommodated my requests, and went above and beyond to make the experience easy for me. I'm impressed with the quality of their work, their attention to detail, and their professionalism. If only all contractors were as dependable.

Had a mini split system installed by Green Collar (Todd and Derrick). Extremely professional and easy to work with. Would recommend!

Green Collar completed my mini split installation. I received professional and very personable treatment from all the staff, from initial consultation, to scheduling, and completion. Todd and Derrick provided all product and service information throughout every step. They made it a point to ask if I had any questions during the process without any hesitation. They were respectable of my home and were always mindful to keep things to minimal interuption. Most of the time I'd forget they were there.I highly recommend using Green Collar.

Jeremiah and his crew were awesome. Very professional and kept our home clean inside and out. Besides that they are very nice people, very polite. It was a pleasure to have them do the work!

We used them to install air source heat pumps (mini splits). Smart skilled helpful staff. Went the extra mile giving quotes to show us our options. Office was very helpful and communicative about the deposit and the 0% interest loan (via Mass Save). Todd and Derrick were a great installation crew, very considerate of our home (even when our dogs were being loud/nosy).
I’m recommending Green Collar to my coworkers and friends.

Green Collar has been very thorough with investigations at my 200 year old house.
We needed to fix all the poor AC repairs made by other contractors. I am very happy with the planning and attention to detail.
I am an experienced construction professional with 20+ years in senior management.

Five star reference

We had such a positive experience with Green Collar. Jeremiah and his crew just finished an insulation and weather sealing project on our home as part of the MassSave program. They were friendly, professional, and efficient. They arrived right on time, wrapped up early, left everything clean and tidy, and were great communicators throughout the day -- explaining everything they were doing and what to expect.

We just had insulation work done with Green Collar through the Mass Save program. They added a bunch of insulation from the attic to the basement. Our house already feels more comfortable! Brandon, Jeremiah and crew were all clean and professional. They were friendly and easy to talk to. We would highly recommend Green Collar and we look forward to our mini split project with them.

Green Collar has been a wonderful company to do business with. From the front office, Gina - who answered all of our questions and set our minds at ease several times; to Daryl - who came to initially measure and came back to the house after the installation to help us with a few minor questions we had; and last, but certainly not least - the installers; Rob, Chris and Kay. When the installers arrived, they asked us where we wanted them to start - instead of telling us what they were going to do. They were all fabulous. Every person we worked with were very respectful, responsive and helpful! We highly recommend Green Collar and will recommend them any chance we get! Out of 5 stars; we give them 6! Thank you all. Lou/Leslee. Pittsfield, Mass.

Working with Green Collar was excellent from start to finish; the quote from Garrett, the efficient scheduling and the crew that showed up right on time. Brandon, Jeremiah, and everyone did a great job. Tyler came on site to inspect during the project. Brandon and Jeremiah kept me informed. I was asked to approve the work regularly as the project progressed. They answered A LOT of questions for me. Work was not complete until I was satisfied with everything. I would highly recommend using Green Collar and would definitely reach out to them for any future projects.

We had a great experience with Green Collar. Brandon and his crew did an amazing job. We couldn't be happier!

Brandon and his team were great! On time and professional. They got the job done in a timely manner and cleaned up nicely when finished. Thank you team!

Everyone that works there was very polite and helpful, John Brent & Todd all were great! Even in this hot humid weather they never complained! Very polite and professional and explained everything. Thank you again.

Thank you to Todd and Derrick, who installed our mini-splits on Wednesday and finished up today, with electricians Scott and Juan. They all did a super neat job and were really polite and nice young men, we are very pleased with their work..thanks! Cecilia T

Todd was here to do the cleaning on my heating pumps. Todd was excellent at answering any questions I ask and was very efficient with the job he done. Great experience!

Brandon and his team were spectacular. Brandon was so personable, professional and an expert in his field. His team was phenomenal as well. Let my house cleaner than when they arrived.

Brandon and his crew did a quality job. They were timely efficient and cleaned up very completely. They also were polite, kind and professional.

Green Collar installed insulation, built an attic fan cover, and more. I was very satisfied with their work, and the company is very responsive if you call and have questions. Juan Ortiz was the person who I dealt with at my house on this project, and he was great.

From the first moment I called GreenCollar, I had a good feeling, and that feeling never left! Estimating was straightforward, scheduling was smooth, and the crew arrived right on time and got right to work. They immediately projected a professional and trustworthy vibe, and I felt very comfortable giving them the run of the place.

My house is small, but complicated: kneewalls, dormers, crawlspaces, and slate roofing… all of which are more than 120 years old! Like any project, there were a couple surprises along the way, but GreenCollar took no shortcuts and figured out how to make it all work. The whole crew was outstanding: Mark, Travis, Miguel, Bryan, Daniel… and a couple other folks whose names I didn’t catch.

Not only did GreenCollar do a TON of excellent work on my house, but they guided me through the process of working with MassSave, telling me who to call and what steps to take next. The estimating and contract process was easy as pie, and with the MassSave incentives, the work was a no-brainer in terms of cost and value to me.

I was very happy with the work process and I’m delighted by the results. The house already feels different: it’s quieter and our AC is not running as much as it used to. I can’t wait to feel the difference next winter!

Excellent experience. the three workers were industrious, polite, friendly and took pride in their work. Juan, Brian and Shawn were respectful of property, left areas of our house cleaner than when they arrived. After learning that a step in the basement was skipped Juan came back and continued with insulation.
We were impressed greatly.

We had insulation blown in our attic and to say we are extremely satisfied with the work done is an understatement! Juan, Bryan and Sean were great! They were courteous, respectful and knowledgeable! Our old home was in safe hands with this team! They did an amazing job cleaning up and even reattached some lose boards from a previous project. They worked so hard the whole day- I was exhausted! Thank you so much guys!

We had insulation blown into our attic floor in conjunction with the mass save incentive program. They did an excellent job! Great cleanup, floor looked better than before they started. Everyone was respectful and responsive, and Juan patiently walked us through each step of the process. Absolutely would recommend!

My house just got done with insulation and air sealing done by Green Collar crew ( Shaun, Wallace & Brian). They did such a great job. They explained of what they were doing and walked me through the project. After they done with the job, they made sure to clean up everything very well. Im impressed and would recommend Green Collar.

We just had a mini split installed today by Green Collar. I was impressed with the knowledge and work ethic of the young men who came. Todd and Derrick really knew what they were doing and were very personable to boot. They were respectful and polite and answered all my questions. The electricians who came were also wonderful especially the poor guy who had to crawl under the house in the dirt to run the wires! I highly recommend this company. I wouldn't hesitate to hire them again!

I had a great experience working with Green Collar from initial consultation, to attic insulation work, to the installation of a whole-home mini-split heat pump system. The team helped me apply for MassSave rebates and financing. I enjoyed working with Garrett and the installation team Wes, Todd and Derek. Everyone was professional, communicative, and provided great service.

Amazing attention to details great job by the team they left the house cleaner than they found it. Wallace Sean and Brian did an absolutely amazing job thank you guys for the help and work

Brandan and his team left the place cleaner than they found it. They vacuumed all the spaces they worked in. The team was very friendly and professional. These guys saved us money and improved our insulation!

4/15/24 Brandon and his crew were incredibly professional. Did their work in a timely fashion and cleaned up as they went.
The day went off without a hitch.

We had Green Collar come out and service our mini split. Brent and John were the guys that showed up and they did a great job! They were thorough throughout the process.

Brandon and his crew were incredibly hard working and left my house clean. Brandon touched base with me about any change in the work as well. My house already feels less drafty and cozy. Thanks again for all the hours put in to do the work and finish the job.

Brandon and the team insulated 4 offices for us over in Ludlow. The were friendly, made sure they didn't interrupt our daily operations and even finished a day early. Thanks guys!

Brandon Crew was awesome, very professional and understanding. They did what they could because of other circumstances but did their job efficiently.

Juan and his crew/Truck #3 just completed a day's worth of work on our house, which included insulating the attic and cellar as well installing new weather stripping on the front door. The entire crew was both efficient and cordial. I would happily have them back and can't recommend them highly enough.

Brandon and crew did a great job of insulating my basement ceiling. They were courteous, thorough, efficient and cleaned up after the job.

Brandon's team was very polite, professional and efficient ! They worked quickly and neatly respecting your home and helping you save energy costs. Highly reccommend this business.

Brandon and his crew, Brian and Andre, were fantastic - capable and careful, they did the job efficiently and even went above and beyond, fixing a duct connection we didn't know was loose. Also nice guys! Highly recommended.

We were assigned Green Collar through the Mass Save program. Brandon and his crew were very professional, respectful, did a great job airsealing and adding insulation to our attic, and left the work area spotless when they left. Would recommend if you need insulation work done.

Green Collar will always be highly recommended by us! They just installed insulation in our Attic and Basement. The installation was stalled (our fault) the first day of a two day job and they came back the following day and worked so hard (and so long!) to complete the job in one day. Juan and his team were outstanding! Polite, considerate, accommodating to all of my questions and considerate of our goofy dog. Left our Home neat and clean. We'll use Green Collar again and will ask for the same crew.

Brandon and his crew did an excellent job. They were on time did great work and a great job of cleaning up before they left.

Great work this week from Brandon's crew! They were early, did an excellent and efficient job, communicated when they were coming and if there were any changes, and were genuinely nice people to work with.

Brandon and his crew were great. Very professional, Brandon explained everything very well and the work they did was great and fast, highly recommend

Brandon and his crew were very knowledgeable, professional, hard working , efficient and friendly. They were able to squeeze me in due to a cancellation due to weather. I would recommend them to anyone
Thanx Fellas

Last week I had Green Collar come in and upgrade the insulation in my home. Since I bought the home, I experienced drafts in certain sections of the home. In some cases in extreme cold weather, the pipes would freeze in one bathroom where the cold air drafts were coming through. The home is a prefab structure which presented some challenges to the team, but they (in discussion with their office) made changes to the original plan and did a remarkable job. They also did a good job cleaning up afterwards. The result of their work is my home is better insulated, warmer and I expect my fuel oil bills to be reduced.

Devon and his crew were wonderful. They showed up when they said they would, kept me informed every step of the way and did a fabulous job. They are great team, very friendly and personable. They were very careful to clean up after themselves as well. They even went out of their way to get approval for needed work that was missed when the initial estimate was done. Highly recommend Green Collar.
