First time served with this company so given a discounted rate.
In terms of pricing, endless energy was much more reasonable than many other companies we received quotes from. They were often significantly cheaper-their price for full ductwork was only slightly more than other companies quotes for minisplit/wallunits. Also, I appreciated that they handle the masssave rebate process themselves and automatically deduct it from the costs. I’ve heard horror stories from people whose paperwork got lost or misfiled and that lost them their rebate; so it was nice to not have to worry about that. I’d like to specifically mention and praise Nick Sherman, who worked with us to get our quote. He was fantastically helpful throughout the process and was incredibly accommodating in working around our parental leave schedules.
As mentioned above, the work took about 2 weeks and was done by the team of Anthony Bullens, Gage Conroy-LaBoeuf, and Cameron Nolette. They did excellent work and worked incredibly hard to get the job done as rapidly as possible. This was especially notable as they were doing the attic work in >90° July weather.
I’d review the materials used but I lack the technical expertise to do so. I can say that, despite what I read online, the Bryant outdoor unit has not been a significant source of noise.
On the customer service side, I’d say there were times that communications got a bit scrambled/lost in rounds of back-and-forth. I think that was largely due to July/august being a busy time of year for them and a specific issue discussed more below.
Their commitment to ensuring I was satisfied with the job is especially commendable. As with any type of job like this, there were a few issues that popped up shortly after the job ended and endless energy had people there within a few days to help fix and diagnose the issues. One issue was particularly difficult to figure out (and was the cause of the back-and-forth mentioned above) but they continued to assist us long after the initial job was completed until we found a working solution.
I would strongly recommend endless energy for electrifying heating/cooling systems and I would recommend the specific people listed above be requested as point-people for any such projects
