@letsbetechs: Sometimes I use what I call the Swiss cheese method to thaw ice off of these coils, if it's a busy day and I can come back in a few hours or if I have other work to do at the same location. Leave the fans running and have the condenser turned off. I find it's way more efficient for me on time to do this method rather than continually running and refilling a pump sprayer and back, removing all the fan guards blades and reassembly, this just typically doesn't take much longer. I definitely don't even try heat guns anymore, Way too long and I don't like milk the job. I would typically use a 2 gallon pump sprayer full of hot water but I'm really enjoying my power sprayer. This is just the way I do it sometimes. If you don't like it for yourself, then don't do it. #hvac #hvacapprentice #hvac #hvacr #refrigerationtech
