Heating & Air Conditioning in Weaverville, NC

Found furnace off on three attempts hard lockout. Tested DC voltage on flame sensor 12.5 DC. Recheck and wire brushed burners and flame sensor. Fire didn’t look like it had a lot of force on it. So I checked gas pressure gas pressure was 1.5 ic. Adjusted gas valve to 3.5.Ic. Tested temperature difference. 60° don’t see any other issues besides the gas pressure that could’ve caused this thing not to fire and lock out.

Replaced blower motor under manufacturers warranty and cycled system to check operation.

Found system emergency heat button pressed on zone control - took out of that function and cycled heat pump in first and second stages to check operation. Did cursory cleaning of furnace burners and flame sensor and cycled furnace to ensure system lights off properly every time.

Found system drain pipe frozen outside causing unit to shut off on pressure switch fault. Removed drain blockage and removed coupling that was causing drain to freeze. Cycled system to check operation. Everything runs normally.

Found spring on damper actuator to be bad. Must replace the damper replaced damper for upstairs tested it no issues found. Found a 16 x 20 x 5 Honeywell filter in a 16 x 20 x 5 filter box. Which is pulling air from the attic into the system will need a 16 x 20 x 5 filter Honeywell replacement filter code FC10081003.

Replaced leaking radiator in rom by laundry room

Was told blower would go on and off every 15 to 30 seconds. Turned on fan at tstat. No issues. Turned on heat. No issues found. Check float switches and wire connections. Cycled system above and below room temp 10 times trying to reproduce the same issue. Each time blower worked s designed. If it happens again, give us a call and we may have to replace the blower motor.

Performed heating maintenance tune up service on heat pump system checking all electrical components, refrigerant balance, unit start up, operation, defrost, shutdown. Changed customer provided filter - flushed drain. Everything looks and runs great!

Replace T6 dual fuel thermostat reprogram thermostat. Set balance point at 35°. Tested heat pump. Raised lockout temperature to 60 tested heat. Furnace came on. Reset balance point to 35 no other issues found.

Replacement of burners and cycling of system to check operation - reduced LP gas pressure from 15" w c. To 11.5" for more efficient burn - cycled system to make sure system lights off every time. Everything looks and runs great!

Found furnace burners are in rough shape and should be replaced. Will call with pricing and availability.

Performed heating maintenance tune up service on gas furnace system checking all electrical components including furnace safeties, performed full combustion analysis checking, CO, CO2, O2, Flue gas temperature, gas pressure, draft. Cleaned furnace burners, flame sensor, flushed drains, traps, collector box, checked furnace filter, treated condensate pump.

Performed heating maintenance tune up service on dual fuel furnace and heat pump system checking all electrical components, refrigerant balance, unit start up, light off, operation, shutdown, performed full combustion analysis of system checking CO, CO2, O2, Flue gas temperature, gas pressure, system safeties, flushed system drains, collector box, traps, treated condensate pump. Found system balance point effected by outdoor temperature sensor failing open not allowing unit to switch between heat pump to furnace. Will order and replace temperature sensor under warranty.

6" start collar had been slightly crushed pulling collar away from trunk box. Bent out start collar and refitted into trunk and sealed penetration. Cycled system on fan high to check operation and for duct leakage. Everything operates normally again.

System air handler in crawlspace made inaccessible by deck joist crossing in front of crawlspace door that swings out. System cannot be fully inspected until crawlspace is accessible. Recommend potentially making door swing into the crawlspace as potential solution. Would be happy to reschedule and complete service once crawlspace is accessible again. Outdoor unit (heat pump condenser) otherwise operates normally.

Replacement of thermostats with Honeywell T6 WiFi thermostats. Performed heating maintenance tune up service on both geothermal systems checking all electrical, refrigerant balance, unit start up, operation, shutdown, geothermal loop and pumps. Everything looks and runs great!

Ultimate Heating Tune-Up Gas Heat: serviced and inspected gas heating system checking air flow, temperature rise, electrical, gas pressure, safeties, controls and limits, heat exchanger and venting. cleaned and checked system components to manufacturer specifications and performed combustion inspection. Pressure gauge no showing pressure so I added pressure with pressure reducing valve and still didn’t move. Don’t think it will be a issue as it only reads pressure and doesn’t control the pressure in the boiler

Found new radiator by laundry room leaking at top compression fitting 3rd in from right. Can’t tighten bolts because lack of space between radiator and nut to get wrench or ratchet on. Will look into if it’s under warranty and availability. Ball valves for radiator and basement were closed to prevent more water leakage. Once the pressure in the radiator equalizes it should stop leaking being that the leak is on top of the radiator sections.

Found 2nd floor air handler circuit board melted along with the majority of all the high and low voltage wires. Replaced board replaced burnt and melted wires. found thermostat to be shorted. Replace thermostat. Tested amp draw of blower motor tested operation. Blower was pulling 1.5 a Everything is running as it should

Replacement of outdoor unit electrical panel under warranty and cycling of system to check operation. Everything looks and runs great!

Replaced batteries in basement sensor. Tested dehumidifier. Inlet- 59%. Outlet-22%. Couldn’t find any issues with dehumidifier No issues found today.

No cooling - found outdoor disconnect flipped to off - found outdoor unit flat on refrigerant - probably why unit disconnect was turned off. Recommend replacement of system. Don't believe system will hold a recharge. System is 24 years old and runs off r-22 refrigerant. See attached tag for outdoor unit for unit model and serial. Scheduled estimate for replacement Tuesday.
