Performed tuneup on carrier AC, checked indoor units drain, blower motor, and temperature split and coil. Went to outdoor unit and checked all electrical and mechanical components, including capacitor, fan motor, and compressor. Tested refrigerant levels, no issues with the unit this time.

Arrived at call for comfort issue, went to boiler and checked all settings, parameters, and reading kn boiler. Noticed the outdoor temperature was off by about 5 degrees from the actual temperature. There is a setting on the boiler to adjust temperature plus or minus 5 degrees so I set it to read 5 degrees below and the boiler immediately ramped up to satisfy, performed combustion analysis and checked over entire system to ensure no other issues were present. Told customer to monitor system overnight and if it still didn't satisfy we would have to replace sensor. House is very old and had one foot thick stone walls, older system in house had cast iron radiators but now has slant fin bas boards when it was renovated.

Perform precision heat tuneup on carrier heat pump system. How many are just replaced 16 x 20 x 1“ air filter. Checked all electrical connections and components. Check temperature rise. Tested emergency heat. Found no surge protection on X 13 blower motor, provided estimate. Tested outdoor capacitor. Checked refrigerant pressures at indoor and outdoor units. Heat pump. System is working fine at time of service.

AC Tune up 3 Ton Carrier Heat pump system. Custom size filter16 3/8”X21 1/2” x 1” in good condition. Measured temperature split and static pressure Inspected indoor and outdoor coil Checked wiring, controls, electric motors and components; left estimates for surge protection Inspected drain and pump. Added treatment tabs to pump. Left estimate for wet switch water safety. Mini R410A refrigerant pressures and diagnostics. Subcoolingmatches manufacturer target 10° System is operating well at this time N

Equipment is 2 Ton Air Temp Heat pump with 10KW electric heat back up. Completed AC tune up. Replaced 14x24x1 filter. Recommend replacing every 2-3 months. Measured temperature split (80-61=19°) Good Tested drain, primary drain runs with lineset and terminates there. Secondary drain is stubbed to right of lineset through attic wall. THERE IS NO WATER/SAFETY DEVICE. Left estimate for EZ trap. Trap with overflow safety device. Inspected wiring and components. Current thermostat does not have control of auxiliary electric heat use. Left estimates for (2) different thermostats which will allow for control of electric heat and save money. Outdoor capacitor is weak. Recommend replacing outdoor capacitor. Left estimate. Monitored refrigerant pressures and diagnostics: ok however head pressure climbs. Homeowner agreed to plan membership, install wet switch and replace weak outdoor capacitor today. Completed work today. System is operating ok at the time of this tune up.
