Came out to check on a heat pump system that was installed by chud in 5/2022. Upon arrival the homeowner stated that the thermostat says it is reaching the temp but she still feels cold. The thermostat was set for 75°F and it was indeed 75°F. I turned the system up to 78°F and observed the system heating. The supply temp is at 112°F, the air filter size 16x25x5 air filter was clogged. I replaced it with a standard filter so the homeowner could run the heat. The homeowner stated that she will purchase her own filter. After about 10 minutes the home had reached the desired temperature of 78°F. The system is operating properly at this time. No charge warranty check.
