Heating & Air Conditioning in Weaverville, NC

Ran system in both heating and cooling operation, found system operates normally in both heat pump and furnace as well as in cooling operation. Found upstairs thermostat settings different from main floor stat. Changes upstairs thermostat to match downstairs thermostat settings. Adjusted balance point on thermostats and zone control panel to all match the same temperature. Tested outdoor temperature sensor, found accurate within a tenth of a degree. Checked system start up, operation, shut down, defrost. Everything looks and runs great! No additional changes required at this time.

Found leak caused by humidifier o rings not sealing base of steam canister when humidifier heats up. Starts off as a slow drip and continues to build as the water bypasses o ring. Replaced steam canister and o ring kit with customer provided canister kit. Cycled system to check operation. Did not note any other leaks on system at this time. Covered as part of tune up. Everything else looks and runs great!

Performed ultimate heating tune up on heat pump system checking all electrical components, refrigerant balance, unit start up, operation, shut down, defrost, electric resistance heat. Everything looks and runs great!

Was informed that in the morning thermostat was on 70° hold house was 68° found the outdoor sensors connected to the zone board which was set to lock out the furnace at 35°. It’s possible that the heat pump is not enough to heat this house Above 68° when it’s below 40° outside we readjusted the furnace lockout to 40° tested the furnace tested the heat pump. Also, second issue could possibly be the registers that is not blowing the air to the ground. Very high ceiling in main room. Bedrooms also have the cheaper type of register. With ceiling returns any warm air that comes out of the register, heads up to the ceiling and get sucked out of the return before the room gets warm if changing the differential on the system doesn’t make a difference I recommend the registers be changed out.

Tested outdoor temperature 1300 ohms correlates to the same outdoor temperature after I reconnected the wires from the sensor to the thermostat wire. The system came on after a time delay. It’s possible that it was a bad connection on one of the wire nuts.

Thermostat was running program instead of permit hold. Reset schedule so each time change is 75 degrees Tstat needs to be in heat and hold.

Found wire common that came off the blower. Had fallen off the board. Adjusted spade clip. Reconnected tested blower. Tested operation of steam. Humidifier to make sure it comes on and shuts off. Everything seems like it’s working well.

System satisfied on arrival. 70 F inside home. Turned temperature up one degree and the furnace came on. No errors or warnings on T stat. Walked outside to condenser and cupped hands around OT sensor to see if it's in Low Temperature lockout. It was, and the system came on after just a few minutes. Went in side to adjust balance point but didn't see an option on the T stat. Adjusted backup heat droop from comfort to 2. It has been below freezing since last night and in the 20s all morning. System is just locking out the compressor like it's supposed to do when below freezing. If the system is going into back up heat when in the 40s there may be a balance issue, but with current temps it appears to be doing what the dual fuel system was designed for.

Replaced 1st stage capacitor. Still threw sparks at me from the common wire after the electrician gave the all clear. System throwing outdoor ambient temp code. Held sensor in hand to warm it up, system came on.

Replaced control board in furnace. No longer throwing pressure switch fault code. Burners coming on cleanly.

Basement furnace has slight noise from age of unit, but nothing to be caused for concern. Typical operating noise. Furnace door is missing a peg, so possible noise is coming from the door occasionally rattling. Ran the system with and without filter. Ran system with door on and off. No over amping from inducer motor or blower motor. Blower wheel is clean. Inducer does not have water backed up; no paddling. Gas valve, pressure switches, burners all operating normally.

Needs board. Calling him when board comes in to Ferguson.

Performed dual fuel maintenance tune up checking all electrical components, refrigerant balance, performed full combustion analysis on furnace, cleaned burners, flame sensor, checked gas pressure, cleaned drain lines, cycled system checking start up, operation, shut down, defrost. 3 flash error code caused by furnace draining slow, after cleaning of drain lines and condensate box for furnace fault did not occur again. Everything looks and runs great! No additional recommended changes at this time.

Installation of iwave r and deep clean of evaporator coil. Recommended running fan in the on position.

Response and diagnostic to check a leak in attic - did not identify any leaks from the attic unit at this time system drain is streaming water and draining effectively and normally to the outside. Insulated drain trap. Attached photo of leak to track development of stain over time.

Replacement of Evaporator Coil out of Manufacturer's Parts Warranty Charged to manufacturers specifications Performed preventative maintenance tune ups. Everything looks and runs great!

System had two separate caps rigged together for 45 mfd. One cap died. Replaced both caps with the appropriate size cap for the system.

Upstairs delta of 17, filter changed, drain line blown out, SC 16 SH 4. Downstairs delta of 19, filter changed, drain line blown out, SC 14 SH 15. Cleaned lawn clippings off both condensers and treated coils with green coil cleaner. Systems are cooling normally.

Found unit was low about 3 Oz of refrigerant believe loss of refrigerant was caused by removal of gauges from last visit. After adding refrigerant and cycling system everything is operating within manufacturers specifications. No additional recommended changes at this time.

Found system filter plugged causing low airflow across evaporator coil. After removing filter system cycles and operates normally indicating system air filter is the culprit for system freezing up. Recommend replacing filter. Can find filters at filterfetch.com using product code: CKT-P4NY

System has a 20° temperature difference ...No other issues found

Board is fried in furnace. Need new board.
