Upon arrival went to airhandler. Customer came with me and noticed all the trash. Coil is clean, sealed up the supply due to air leakage, and looked at all the duct work. Took pictures of everything. Indoor unit is running, went outside, tested outdoor pressures and they where where the manufacturing called for 6°-7° subcool for the temperature outside. Attic could use new insolation and I explained that to the customer. Went inside and checked the thermostat and everything seems to be set up correctly. Explained to customer I will be talking to a manager Blount this job for him.
