Aspen Environmental is a great company to work with. From the first phone call I made to them to the last visit to our house to finish the work they were professional, friendly and knowledgeable. Every interaction with the company was great. Office folks were friendly, workers at the house were excellent and the follow-up on all aspects of the work was thorough. We had air sealing and insulation work done via the Mass Save program. Would absolutely use them again for any services they offer.

Aspen came to repair blown in cellulose that was mistakenly pumped into my HVAC system. They did a great job remedying the situation. They were respectful, attentive, clean, and thoughtful. After my good experience I contacted them about having my ducts sealed with aeroseal. I have a one zone home so having an efficient system was critical for me. Cori and his team were attentive, educating, and thoughtful. They walked me through the measurements and were able to reduce my duct leakage by 85 percent! Having run my ac for the past week it is clearly more efficient and getting improved airflow. Once they left, I realized they tripped a circuit and I couldn't find the outlet. They sent a guy right over and fixed the simple mistake. Seemingly good people over there doing good work!

While having our central AC replaced we found there was a leak that had likely been going on for months creating a significant amount of water damage & mold in the walls. Joel & Angel came in, removed all of the wet & moldy surfaces, and treated the areas thoroughly with safe treatments. They were kind, professional, on time, respectful. Everyone I have dealt with from the office staff to the technicians have been nothing short of wonderful to work with! I would highly recommend choosing them!!

We had flooding and a pipe crack over the past year that caused major water damage. In both instances Aspen came asap and did a great job mitigating the damage. They also use green cleaners that are good on the lungs! Working through insurance was easy as well. Highly recommend using James, Damien, and their entire team! They were super responsive to every question, highly recommended!
