Customer stated unit wasn’t cooling and froze up. Checked unit and found system to be low on r22. Siam r system was from 1997 and unit ran on r22 talked with customer and decided a replacement would be best option. Customer signed estimate to replace furnace and ac. Customer got approved by greensky. Let customer know we would try to make it out tomorrow to get unit swapped out to work with us but we would at least get prep work done tomorrow. Also mentioned we could bring portable ac if system doesn’t get installed tomorrow.
