Customer went over house and duct system with me. Found several flex’s leaking tons of air. Found that a lot of the duct work will need re done. Plus recommended replacement of old oil furnace and a/c system. Also customer would like a ductless System installed in the grage. Will go over findings with the office , will have someone come out to give a proper estimate on the work that needs done. Also checked a/c pressures on roughly 27 year old a/c system.
Performed Quality Assurance on Amana Gas Furnace/AC system. Unlocked thermostat for homeowner and showed her how to operate the thermostat. Reviewed installation with homeowner. Completed checklist form in system. This did not pass the QA inspection.
Found blown 30-5 MTD capacitor for 2Ton Trane XR 15 Heat pump. Cooled compressor with running water. Replaced capacitor. Tested system operation. Compressor amps 4.0; ok condenser fan amps .76; ok. 18F temp split (76F return- 58F supply. Filter ok. Cycled system once more. Left thermostat calling for cooling 70F. System is operating well at the time of this service.
Recovered refrigerant and changed disconnect box with a new disconnect and whip. Replaced old Bryant outdoor with new Amana ac outdoor. Laid down rocks and leveled out on a pad. Flushed line set. Per customer we put whole 4x4 iso pads under unit. Replaced gas furnace and coil with new Amana gas furnace and coil. Caulked all gaps and outdoor disconnect and the gap from the copper line set. Installed new Honeywell T6 and removed old thermostat. Installed TXV valve into coil. Modify supply duct and taped all seams as needed. Installed new condensate pump with vinyl tubing and installed EZ trap wired in. Ran new electrical box with MC wire down to a switch and outlet box. Modify filter to be 16x25x1.
Found after giving thermostat a call for cooling fan came on and also compressor. Checked temperature split at package unit. Had about a 33 degree split and also heard a banging noise at the ceiling when blower first came on. Temperature on the supply side was around 36 degrees very close to freezing. Took off supply flex and found fire damper fusible link broken. Secured fire damper back open and zip tied flex back on. Will need to find a new fuseable link and return to install on fire damper. Will locate a reach out with a price to replace fusable link. For now System is cooling just fine with a 19 degree split. A/c is working fine at time of service.
Found system fan consistently running with thermostat in auto mode. Pulled thermostat wires off at package unit and fan continued to run. Checked to make sure safteys are closed. Thought a first it was the control board than after talking to Wayne it was also ver cooling the thermostat. Had to pull out all electrical guts and found burnt up contactor sticking shut. Installed new contactor and ran system in a/c mode and cycled off. System is working fine again at time of service.
Went up with Seth to apartment out to magic pac system. Put blower motor in fan on position. Had no mechanical noise. Took off panels which were very difficult to remove to acces blower motor, blower motor was intact. As soon as compressor started you can hear loud internal mechanical noise. Wayne and I removed the internal guts of the system and evaporator condenser coil and compressor all slide out on a tray. There is ports to hook up to unit but can not run the system at the same time. System is cooling just fine. Checked compressor bolts , compressor bolts are tight. Compressor itself is make a loud vibration when it runs. Wayne is going to talk to higher up to see next step on repair.
When we arrived at the building meet with Wayne to look at magic pac gas and a/c unit. Went up to apartment 407. Soap checked gas fittings. Turned on system for a call for heat and had a fire flash inside unit off of the manifold pipe. Had to remove entire gas valve and manifold and found a pin hole in the metal of the manifold itself( this was very difficult to remove. Turned off power to system and used drip leg cap to cap off gas line for now. Will get the price and availability to replace manifold pipe. Also checked gas pressure at gas valve natural gas was reading 3.5 w.c.
Performed Precision Heating Tune Up on 1st Floor and 2nd Floor Gas Furnace Systems. Replaced High Efficiency 413 Filters on both system. Cleaned drain lines and Condensation pumps. Inspected Electrical Components on each system. Removed and cleaned Flame Sensors and inspected Burners. Performed Combustion Test on each unit and measured Gas Pressures. Both systems were running in Low Stage Heat during testing. Systems operating to standards.
Performed peco inspection, checked air filter ok. Cleaned condensate trap and drain. Tested electric back up heaters. Checked voltage, amperage and electrical connections, measured capacitor values. Started heat pump, calculated btu output. Tested defrost cycle. Checked operation and temperature rise across coil.
Performed heating maintenance, checked air filters ok. Cleaned burners and flame sensors, inspected heat exchangers. Blew out condensate trap and drain. Checked voltage, amperage and electrical connections. Serviced humidifier, cleaned and replaced water panel. Started humidifier, set humidistat to 35% rh. Started gas furnaces, tested limit and safety switches, measured fuel pressures. Checked operation and temperature rise.
Performed Precision Heating Tune Up on Gas Fired Furnace. Replaced 16x20x1 Air Filter. While testing electrical components, found Blower Capacitor testing below rating. Replaced Blower Capacitor and tested operation. Cleaned Pressure switch tubing which was blocked with buildup. Inspected Heat Exchanger and Burner Assembly. Put system in Heating Mode and Measured Amp Draw on Inducer Motor and performed Combustion Analysis of Furnace. Combustion readings were within standards and Air Temperature readings were within standards. During tune up noted that on the Gas Line there is an Union Fitting inside of the Furnace Cabinet. Would recommend repiping the Gas Line to remove this fitting from inside the Furnace as these fittings may leak, which would be a major safety issue. Tested fitting with leak solution and found no leaks at this time. Also found old Humidifier had been abandoned. Would recommend either removing and sealing the duct work or replacing with a new Humidifier. The old hu
Checked no cooling complaint, found blower running but no outdoor unit. Checked outdoor unit, found no power to unit. Breaker tripped. Checked for shorts and grounds, found none. Reset breaker. Started air conditioner, could not check charge due to rusted king valve. Checked air filter ok. Checked temperature drop across coil.
No ac found system running upon arrival, found system to be low on refrigerant, quoted to add refrigerant and customer ok with pricing added close to 3 lbs of r22 check system performance supply air 60 return air 79 system is from 1998 would highly recommend replacing system, by adding refrigerant today’s system is up running, explained land lord that there is no guarantee on how long the refrigerant can last, could leak next week, next month or in couple days, customer is aware situation
Performed Precision AC tune up on First Floor and Second Floor systems. Both Aprilaire 413 Filters were excessively dirty and needed to be replaced. Tested electrical components on both the indoor and outdoor units. Found the Hard Start Capacitors for each outdoor units are corroding which indicates that they failing. Recommend replacement of both the 88-108 Mfd Start Capacitors with Starting Relay. Measured Air temperatures on each system. Adjusted fan speed settings to increase Air Flow for each unit. While testing systems the drain lines for each system are gravity drains into a stand pipe behind the water heater. The standpipe started to back up and overflow which is the cause of the water on the floor. This standpipe needs to be snaked to clear the blockage or it will continue to overflow. There is no access to clean out the Condensation Drain Pipes. Recommend installation of EZ Traps onto both AC Units to allow better access to clean the PVC drains.
