Upon my arrival, I checked into the customers concerns with the indoor system freezing over. After allowing the system to thaw out a little longer, I found that it was low on refrigerant. I spoke with the customer about my concerns and recommended adding charge to the unit and with their approval I did so. After acquiring the proper sub, cool value, and then checked the system’s temperature finding the unit is now cooling well. I did find that the indoor coil has become dirty due to pulling air from underneath the home and recommended having the gap sealed with spray foam. Customers are currently in the process of building a home and don’t plan to be in there but a couple more months and would like to not have to put any more money into it if they don’t have to. There is potential that they may look into using us to quote putting in the new system on their new home. I left customers with a card so they could reach out.
