Performed precision heat tune up on trane heat pump. Replaced dirty 20x22x1 air filter. ( recommended to homeowner to change more often, showed her how to change it). Checked all electrical conections and components. Checked refrigerant pressures and temperatures at indoor and outdoor units. System is working fine at time of service. Installed surge protector.
Ran 10inch Return to the new room as well as a 6 inch supply vent. Put in mini split with outdoor unit ran line hide new disconnect drain and refrigerant lines inside line hide ran new power wire and tied into electrical panel with new 20 amp double poll breaker unit was triple evacuated and held pressure for 25 minutes. Unit was vacuumed down to 100 microns and held for 20 minutes... system is charged and running to factory standards. Went over everything with customer.
Replace gas valve on first floor system test and cycle furnace ok check for gas leaks on work performed no leaks combustion test ok system is running at no issues
No heat return visit to continue troubleshooting, after checking gas pressures incoming and manifold, check all grounding, furnace drain, found out bad connection on gas valve, contact Amana tech support and both agreed that gas valve should be replaced,
No heat, found furnace running upon arrival, check heater operation and test ok check errors on history found E0 ignition lock out, check all electrical, ground wire ok, check pressure switch and tubing ok, could not get furnace to failed did not din any issues, talked to Amana Rep, and he recommend to check heat exchanger for any leaks, inspect exchanger found lot of areas with rust, looks like condensation is getting to exchanger, could not check exchanger with my camera we will need a High definition camera and try to inspect heat exchanger deeper, return visit is need to check heat exchanger
Installed new pressure switch under warranty. Also found one of the pressure switch hoses to be a little loose. Re secured pressure switch hose with zip tie to make tight connection. Ran furnace for about 20 minutes and had no issues with it cutting out on any error codes. Also checked outside exahaust vent for debris, vent is clear. As furnace was running it displayed an e3 error code which is high limit code. Increased fan speed by 5% trim to help with temp rise. Now have a 51 degree temperature rise. Homeowner also would like an estimate from our office to add supplies and returns downstairs off of existing duct work.
Service call that the Gas Furnace for the First Floor of the Home was not working. Upon arrival found furnace in the EO Error Code. Tested system and found Proper Pressure at the Front Door Pressure Switch. Pressure switch did not close on several attempts for the furnace to fire. The pressure switch began closing after several ignition retries. Exercised the Pressure Switch and the contacts were closing. Restarted system and cycled multiple times to ensure the Furnace was firing. Will follow up about replacement of the Pressure Switch.
Removed Reme air scrubbers and inspected cells. Found cells not connected properly to wiring harness. Reconnected sales for downstairs and upstairs unit and tested operation. Back to downstairs furnace and clean drain lines and install vent on condensate drain line. Removed and inspected and clean flame sensor. Removed pressure switch tubing line and inspected and found small crack, replaced tubing line. Checked over all wiring harnesses and connections, and tested grounds. Tested furnace to ensure proper operation.
Homeowner called about water damage on the ceiling. Found mold and growth in the Bathroom Linen Closet. Found area in attic where damage to the drywall was occurring. Found no signs of water present during visit. Inspected Vent Piping and Condensation Drain Line. Inspected Refrigerant Pipes to insure it was insulated. This area is directly below the Exhaust Pipe where it terminates out of the roof. The Roof Flashing May be leaking and the water is running down the exhaust pipe. Also checked Reme Halo Air Cleaners on both systems. Both Air Cleaners are receiving the 24 Volts but are not turning on. Checked Ballast Connections. Checked Transformer wiring on both units. Need to replace both Remes. When we return to install the Remes we will further diagnose the First Floor system.
Service call that the First Floor system was not heating. Upon arrival found Furnace in a E0 Lockout Code. While testing system, unit began to operate. Checked Pressures on the Pressure Switches. Cleaned Flame Sensor and measured Micro-Amps which were measuring about 1.5 Micro-Amps. Measured Resistance across the Ignitor at 66 Ohms. Cycled system multiple times to ensure it was firing properly.
Returned to site to install new Control Board. Turned Power off to system and removed the old Control Board. Mounted new Control Board and made all wiring connections. Reviewed Dip-Switch settings on system and set all Dip-Switches. Reviewed Wiring on system and put system in operation. Checked Pressure Switch Tubing. Tested system in Heating and Cooling Modes to insure that it was running properly. System Was responding to the thermostat properly and is operating to standards at this time. While inspecting system, found Reme Halo Air Cleaner was not operating. Checked unit and verified that it was receiving proper voltage. Would recommend replacement of the Cell Membrane on unit. Reme recommends replacement of cell membrane every 2 Years for optimal performance. Homeowner has purchased new Cell and is going to replace. After testing system, found the Fan was continuing to run between cycles. The thermostat was not calling for Fan but was receiving 24V signal at the Board on the G
Checked no heat complaint, found no lock out but have a call to w1&w2, inducer is the only thing running. Rebooted control. Cycled furnace and furnace ran on low and high fire. Checked fuel pressures ok. Can not get furnace to no the same thing again. Recommend replacing furnace control board. This is the third time this happened. Model # AMVC960804CN. Serial # 1704483268 Board serial # c170951155 Gp/npcbkf105 Part ordered thru Hvac distributors
Installation of an Aprilaire 600M Bypass Style Humidifier onto the system. Run new Water Supply Line to the Water Heater Piping to feed Humidifier. Run Drain Line into Condensation Pump. Performed heating maintenance, checked air filter. Inspected heat exchanger. Cleaned burners and flame sensor. Blew out condensate trap. Started gas furnace, tested limit and safety switches, performed combustion test. Measured fuel pressures. Checked operation and temperature rise. Install Aprilaire 600 humidifier. Piped and wired humidifier. Set up thermostat to control humidifier. Started humidifier and checked operation. Set humidifier to maintain 35%RH.
Performed precision heat tune up on 2 amana gas furnaces. Both Aprilaire 413 air filters are clean. Checked all electrical conections and components. Blew out both condensate drains. Checked gas pressure and performed combustion tests on both systems. Serviced humidifier on first floor system with number 35 pad. Checked temperature rise on both systems. Both amana gas furnaces are working fine at time of service.
Performed Precision Heating Tune Up on Gas Boiler. Was informed by Homeowner that the Boiler intermittently turns on even when it is turned off at the Thermostats. Boiler was turned off at the Power Switch in the Basement. Performed Heating Tune Up on System. Removed and cleaned Burners and Pilot Assembly. Inspected Heat Exchanger. Inspected Wiring for System and at Thermostats. Tested operation of system for both zones. Cycled system several times and found that the Circulator Pump was continuously running. Determined that the Fan Control Center Relay was sticking causing the Circulator Pump to remain on. If this Relay was sticking, it would also intermittently turn the Boiler to run even without a Call for Heat. Turned Power off to the Boiler and removed the Fan Center. Installed a new Honeywell Universal Control Center. Made all wiring connections. Put system back in operation to test. Tested each Zone and monitored Boiler to ensure it was turning on/off properly.
