I have unfortunately used these guys multiple times on a few different projects, mostly due to…read moreavailability of other trades and the fact that they are a larger outfit, and some of the builds we have done were multi-million dollar builds. However, they do not stand by their work. They have poor craftsmanship and will argue terrible points instead of just getting the job done. I'm very unhappy with their service and installation. While they may have one or two great technicians on their team, as a whole, I would not recommend Casper's.
We had hired them expecting them to be the experts and follow suit with their claim of being the best heating and plumbing guys in town. However, we have found that they are not able to identify new and cutting-edge technology to make things work. And oddly enough, they, in an area of mostly historic buildings, do not know how to treat a historic building in such a way that it is best protected from the elements while balancing their air conditioning and/or furnace installations. One of our buildings has experienced severe sweating due to the humidity because they decided that because we were transitioning a commercial building into a residential building in a historical district, that it did not need insulation around the ductwork. Being a commercial installer for other trades in the electronic and tech field, I see many ceilings, and every one of them has insulated ductwork. This was an atrocious neglect by Casper's design engineers, and when addressed after we had problems with condensation ruining the drywall in a multi-million-dollar mansion, we are being told that that's just the way they do things and work.
On another installation of, again, a historic building that was once commercial turned into residential, they pulled the same stunt without insulating the ductwork and improper placement of the ducts. So while we spent one summer horribly unbalanced and incapable of achieving a good air-conditioned space upstairs and down, the next summer, after getting some of the balancing issues worked out, the humidity was so bad that it rotted and molded the ceiling of our building, unbeknownst to us. We did not see it until some of the paneling started to fall and filled the room with mold spores. Again, they would not warranty their work.
And a third time, I did not hire them for this work directly. They were hired indirectly by another party. However, I assisted with an install of an air conditioning unit inside of a building, of which they left the drip pan resting on the rafters with no screws and the drain line free air hanging in the middle of the room, not affixing to any pole or aiming towards an appropriate drain exit. Admittedly, this was a very custom build. However, it was left in a very poor position for me to finish, with no communication about how they left the situation nor ideas or solutions to complete the installation.
I will not ever intentionally use their services or hire them again, and I would not suggest them to anyone else either.
