Upon arrival did visual inspection on 1984 Lennox coil and AC made it to a 1984 carrier electric furnace. System physically is in poor condition. With approval from customer performed thorough inspection on system. Customer states the fan always runs. Upon inspection of this furnace it is on 100 amp breaker. While running in heat mode, it is pulling 80 A. This furnace is old and poor condition and incredibly inefficient. New equipment will take a third of this electricity and its highest modes to heat this home. Did find relay for fan to be closed all the time. The fan needs a relay. This needs a two relay that’ll work for heat and cool. This motor was recently replaced. As well as thermostat. This was done by handyman. I do not recommend putting any money into the system. It is simply way past. It’s prom and in poor condition. Switched to AC and tested AC AC is cooling pressure is a little low but not bad. Contact Meir is very burnt and pitted and buzzing. Needs to be replaced. I will
