All reviews for CRS Mechanical LLC

Working with Kason , and his crew on a more professional basis. Working side by side on jobs, either new installs,service work, and the occasional emergenc calls. Always respectful, and knowledgeable. I refer these guys to all my customers and builders.

best service and staff, when called i the communication was smooth and they came same day. provided excellent service to my heating system when I had no heat in the house. highly recommended. Thank you Kason.

did a service call today they came quick Isaac the technician resolve my issue and made sure my system works before he left.

Kason is truly the best. Not only does he answer every time we call for any issue, but he or Connor, show up the same day which is huge when you run a small business! We needed a walk in freezer repair at our catering business- Kason was there on Wednesday to investigate, called me the same day with an estimate and we had the install on Friday. He is meticulous, precise and very knowledgeable. Kason has checked in the last few days to make sure things are still running smoothly and the freezer is doing its job- where can you find better customer service? I know we are a CRS Mechanical customer for life now.

Kason and his company really came through for me when my previous furnace finally broke. They gave me the tough news but worked with me on getting the best product at the best price. They came the *very* next day to install the new furnace for me and moved their schedule around to help me. Their crew was great and ensured everything went smoothly and my new furnace runs even better than the old one. Thanks again and I will be using them for any other issues I may have in the future!

CRS Mechanical fully lives up to the promise on their web site.
We hired Kason and his crew to install a mini-split in our new home in 2023. They did such an extraordinary job, that we had them back to install another mini-split in 2024 in our renovated addition. Again - superb workmanship! We had them replace our gas furnace with a new high efficiency model in February of 2025. Not only did they install the furnace, they fixed the door latch to our garage storm door. Way over and above expectations. A true gem of an HVAC contractor. You don't find many like these guys anymore.

We hired CRS Mechancial to replace our old furnace and air conditioner after getting several competitive quotes. They provided the best value with a quality Bosch system that was installed for substantially less than the larger companies.

Kason and the team were fast, professional, friendly, and did a great job with the install. They usually do commercial work, but did a first-rate job for this homeowner. We’ll be calling them for any future HVAC needs and would recommend them to anyone.

Kason and all of the CRS staff and crew are top notch. They have always been incredibly responsive to us when we have needed service or a full system replacement. Could not recommend enough!

CRS and Kason the owner is A1 top notch service with local roots in Concord and NH area.
I had an emergency problem no heat frozen pipes I left a message and he called
Me back within minutes he helped me with a BIG problem with a simple solution!
He had walked me through hat I needed to do and I was able to fix it in my own.
But he could have easily came out on an emergency service and made a quick buck. But CRS cares about there customers and community

Any HVAC problems call them thank you Kason and your team for being caring professional and prompt!
