Paid $2400 for a job that was done by an handyman. Handyman charged $650. / Columbia gas said new furnace line was checked and approved. Handyman not certified by city. Had to find someone who could request permit. This company came , mind you everything was already done.replaced 2 or 3 panels , done that to make sure all was well and charged $2,400 for a job already done. Just for the permit. Word to the wise
Came in for a routine AC maintenance call. For no reason, the technician decided to take apart the entire furnace and then claimed there was a leak in the heat exchanger after supposedly seeing a microscopic scratch. He didn’t perform any other inspections to verify whether there was actually a leak. When asked to leave the home, he refused and threatened to call the gas company to shut off my gas. How can you declare that there’s a crack without actually removing the part or performing any proper inspection? Obviously there was nothing wrong, but they get paid to sell, so the technician is incentivized to lie. I’ve been trying to reach someone at the company for months with no luck.

Brad is the man! Very personable and professional. Not only found the problem quickly but instructed me on how to maintain my system between services. I'll recommend Dormar not only for the service they provide, but because of techs like Brad and their arsenal of service technicians.
Derrick was extremely professional and educational. Unlike many technicians he truly took the time to help me understand the problem and not run up my bill because I was unknowledgeable. Highly recommend DorMar specifically Derrick!
Not sure if the wires are supposed to be hanging out after a brand new install of the air handler. The heat pump looks great from what I can tell but I’m not a professional. Otherwise 4 stars for now until I hear back from an install manager. The initial tech that came out was super informative and helped us get the right system without trying to upsell us. The install techs were quick and were polite HVAC is now working and wife is happy.
