"Both the main and secondary condensate drains were clogged and the service technician cleared them. He also cleaned filters and verified proper operation of all equipment. We intend to use Carini for future annual checkups and needed service.

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."
