This company added refridgerant 3 times over a 3 year period to my unit. And during these visits, Alan (the owner) never once go up in the attic to inspect the evap coil. He worked exclusively outside by the condenser unit. This summer, my unit stopped cooling again and I decided to get a second opinion. The attending tech went up into the attic and inspected the evap coil. He did a leak test and determined that the evap coil had a faulty valve. They replaced the valve and recharged the refridgerant for less than what Renegade Heating charged to recharge it in 2018, with no repairs. I am profoundly disappointed with Renegade Heating. I like to support small businesses and thought they were doing right by me. I would not recommend doing business with Renegade Heating to family and friends. They are not about diagnosing problems and providing permanent fixes. Save your hard earned money by hiring a company that cares about diagnosing and fixing problems rather than applying short-term band-aids.
