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.

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. Thank you for ren
Performed PECO check, replaced standard air filter, blew out condensate trap. Inspected cooling coils. Checked voltage, amperage and electrical connections, measured capacitor values ok. Started heat pump, checked refrigerant charge and temperature drop across coil.
Pump Down Refrigerant and remove the old TXV. Install a new TXV Metering Device. Pressure test system for 10 minutes at 300 PSI of Nitrogen to ensure there are no leaks. Perform a triple evacuation on system. Release Refrigerant to the entire system and test operation. Add additional Refrigerant to system if needed. Complete AC Tune Up on system. Please be advised that there may be further issues that are found after the TXV is replaced that cannot be diagnosed at this time due to the restricted TXV. Replace txv, pump system down into the outdoor unit. Removed failed txv. Pressure tested to 350 psi for 5 minutes. Evacuated system to 425 microns, held for 5 minutes. Open refrigerant valves. Started air conditioner, balanced refrigerant charge by sub cooling, checked operation and temperature drop across coil.
Service call that the AC System was not cooling properly. Upon arrival, spoke with Homeowner about issue. Found system was set to 71 Degrees and the Indoor Temperature was at 73 Degrees. The Indoor Coil was leaking and the Auxiliary Drain Pan was full of Water. Cleaned water from the Auxiliary Drain Pan. Inspected Coil and Filter to ensure they were clear. Measured Supply and Return Air Temperatures on System which was only producing about a 10 Degree Differential. Checked Air Flow Settings and measured Refrigerant Charge. Liquid Pressures/Temperatures were normal but the Suction Temperatures were very low and the Indoor Coil Temperature was at about 9 Degrees. Air Flow Settings were slightly lower than recommended for a 4 Ton System. Increased the Air Flow speed and continued to monitored. To test the Metering Device, added 12 oz of 410-A Refrigerant to the System. The Liquid Pressures and Subcooling Increased while the Suction Pressures remained the same. The TXV has a restriction wh
Performed precision ac tune up on 2 amana acs. Replaced 2 Aprilaire 413 air filters. Found one reme the indicator light for the bulb was not lite indicating to replace the reme cell. After re powering light came back on but both are right around the 2 year mark so recommended replacing both cells. Checked all electrical conections and components. Checked refrigerant pressures and temperatures at indoor and outdoor units. Blew out both condensate drains and also washed off both condenser coils with a hose. Systems are running to manufacture specifications.
Performed Precision AC Tune Up on Air Handler/AC System. Replaced 24x24x1 Air Filter. Cleared Condensation Drain Pipe and Auxiliary Drain Pan Pipe. Tested operation of Auxiliary Pan Float Switch. While inspecting Electrical Components on System, found Blower Capacitor testing below rating. Also found Dual Capacitor for Outdoor Unit was excessively rusted and in poor condition. Spoke with Homeowner about issues with Capacitors. Installed a new 10 Mfd Blower Motor Capacitor for the Air Handler. Installed a new 60/5 Mfd Dual Capacitor for the Outdoor Unit. Found Outdoor Unit Coil Dirty with Lint from nearby Dryer Vent. Washed Outdoor Unit with Water to clean Coil. Measured Refrigerant Charge on system. Spoke with Homeowner about installation of an EZ Trap and Wet Switch for the Attic Air Handler. There is a Float Switch Installed on the Auxiliary Pan but the Wet Switch is a more effective Device to detect water in the Drain Pan. The Condensation Drain Pipe currently has no safety devic

Performed Precision Air Conditioning Tune Up on Carrier System. Changed 16x25x1 Air Filter with Filter provided by Homeowner. Inspected Electrical Components on Indoor and Outdoor Units. Inspected Indoor Coil and cleaned Drain Line and Condensation Pump. Measured Refrigerant Charge on system and measured Supply and Return Air Temperatures. System is operating to standards at this time. Would recommend installation of an EZ Trap onto the AC Drain Line. This would provide an added layer of water safety protection, and also allow more thorough cleaning of the Drain. The EZ Trap has an internal Float Switch that shuts power off to the unit if it becomes clogged. This Drain Enhancement would compliment the Float Switch that is installed in the Auxiliary Pan underneath the Furnace. Installed EZ Trap and adapted to existing Condensation Drain Piping. Installed a Union on the Lower part of Drain Line to allow easier access to remove Pump. Wired EZ Trap in series with the Pump and Float Swi
Cut out 2in pvc and replaced with 3in pvc. Installed 3in fresh air return.
No heat first floor found unit locked out on code E0, fail to start, check drain electrical ok, reset couple times until furnace run ok, noticed intermittent problem, we would need to get back to site to repair vent pipe there is a reduction from 3 in to 2 in on horizontal as the vent pipe makes its exit of the house, will be though since water heater and return duct is fight on the way of the flue pipe, Offcie to coordinate to shedule another visit
