My A/C wasn’t working last weekend so I called Chase Roberts, since they were the company that installed my A/C unit 5 years ago and the only company that we’ve had service the unit. When we scheduled the appointment, we were told that there is a service charge of $ 85 for a technician to come out and look at the A/C unit. When the technician arrived, he said that there would be an additional charge of $ 125 for an electronic leak detector test. The tech spent only a few minutes inspecting the A/C unit(while talking on his cell phone the entire time). He quickly concluded that the evaporative coil was leaking and that the repair would cost around $ 2,700 but for $ 3,000– $ 5,000 we could purchase a new unit that comes with a one year warranty. They said that the unit they installed 5 years ago was past its warranty. I called Naughton’s Plumbing who recommended two companies; one of which was Gotham Heating and Cooling. I called the owner, Mike, after 5:00PM and he scheduled an appointment at my house the following afternoon. Abel and another tech arrived on time and spent 2 hours at my house inspecting the A/C unit and performing an electronic leak detection test. They did not find a leak but had, however, found that Chase Roberts had previously duck taped over two vent opening in my attic. They showed me pictures. We weren’t getting enough cool air in the house so we paid Chase Roberts to come out and adjust the vents in our attic(according to what they recommended) but, apparently they had just taped over the vents. This caused a greater demand on the A/C unit to use freon so the freon was very low. Abel and the other tech from Gotham actually took me around the house with the leak detector to show me that the instrument was not registering any leaks. They also explained what other physical signs would be present to indicate that there was a leak and showed me how I could look for those signs. The then filled the freon levels and showed me again that there was no leak after refilling the freon. Best of all, they used their freon tank and the detector to show me what trace amount of freon would actually trigger the detector. In other words, the detector definitely should have registered a leak after they refilled the freon. My total bill for two A/C techs to spend 2 hours at my house and actually resolve the problem, was only $ 270.00. That included 5 pounds of freeon for $ 150, $ 90 labor, and $ 15 travel charge. It cost less to have Gotham actually fix the problem than for Chase Roberts to misdiagnose it. Gotham worked around my schedule and at my request, came by the house at 3:00PM, which likely means that the two techs were working past their quitting time. Mike, Abel, and the other technician were so professional and personable. I can’t believe how honest and reasonable they were. I actually feel bad that they didn’t charge me more for their services. I strongly recommend Gotham fro your heating and cooling needs.
