Newtown Square, PA

Upon arrival for a no heat I turned on tstat and proceeded to attic. I found the unit cycling but not firing. Noticed that the ball valve was closed for gas supply. Turned on gas and unit came on. Checked gas pressures 1.6/3.5. Performed combustion test. Unit is in normal operation.

Upon arrival for maintenance on gas furnace I changed air filter. Changed water panel and did maintenance on humidifier. I cleaned the flame sensor. I inspected heat exchanger and burners. I checked blower motor and assembly. I checked the resistance of igniter. Checked all wiring and control board. I checked inducer operation and ensured hose port was clear. I checked gas pressures. Checked air temperature rise. Performed combustion test. Unit is in normal operation at this time. Upon arrival for heat maintenance on heat pump tune up I changed the filter. Checked electrical and wiring and emergency heat kit. Checked blower motor and assembly. Checked delta t. Inspected coils. Checked fan motor and assembly. Unit is in normal operation at this time.

Performed precision heat pump tuneup on five heat pump systems. Replaced one 16 x 25 x 1“ air filter, replaced two 16 x 20 x 1“ air filters, replaced two 20 x 20 by one air filters. Serviced three humidifiers with number 35 humidifier pads and tested operation. Found UV system broken on dining room air handler, provided estimate to install Apco XUV air purifier. Checked operation of emergency heat on all systems. Check temperature rise on all systems. Tested out to work capacitors. Check refrigerant pressures and temperatures at indoor and outdoor units. All heat pumps are working at time of service.

Performed tune up on rheem gas furnace ran unit in heating mode and tested combustion as well as gas pressures. Temperature split was taken across unit and filter was changed, unit is spark ignition so ignition rod was tested and cleaned as well as flame sensor burners were inspected as well as heat exchanger and blower motor no issues with unit unit at this time, customer was given estimate on service agreement, but she denied at this time

Turn power supply off to system. Disconnect and remove the Reme LED. Install a new LED Cell for the unit and reinstall. Turn power supply on and put system into operation. Cycle system and verify Reme is turning on/off correctly. Ofter installation of a new Reme cell find out that the light is not displaying check voltage to it getting 24 volts but it’s not displaying to display board. We need to contact manufacturer is unit is under warranty. Office to follow up with customer other answer on next step.

Perform heat pump, tuneup inspection, check electrical low and high voltage connections and components. Inspect air filter ok. test back up heat airflow supply and return air temperatures. OK 86 supply 66 return. Outdoor unit refrigerant pressures ok test defrost and cycle unit ok. During today’s visit, I had to remove 5 kw heat from back up heat due to wiring overheating and using wire nuts. Unit is now running on 10 kw talked to customer about this and provided an estimate if they want us to connect other 5 kw heater, we will need to run new 10/2 wire and 30 amp double pole breaker. Customer should be fine with 10 kw. Also they use fire place to reduce electric heat usage.

Performed commercial maintenance on 35 year-old carrier gas furnace. Replaced 20 x 20 x 1“ air filter. Checked all electrical connections and components. Inspected heat exchanger did find a decent amount of rust on heat exchanger. Check temperature rise. Inspected thermocouple. Tested blower capacitor. System is a downflow in a closet. Inspected burners. Perform combustion test. Found system only running at 77% efficiency and is also very old. Would recommend replacement of gas furnace AC. Explain this to business owner. He would need to speak with the landlord to make any decisions.

Reviewed equipment and took measurements. Created and provided quote for replacement options. Need to review to see how we will get equipment on the roof and if there are other options that meet tax credit that are non inverter.

Fully assessed gas leaking situation. Found several gas leaks on main header on 2 1/2 inch lines that feed all the gas stoves in the apartments above. Also found track pipe, mechanical adapter leaking at brass connection. Explain to the maintenance guy that I wasn’t sure whether this would be contractor or it would be peco. Our office to determine next steps.

The celling needs to be removed before we can look at it. Everything is dry walled in.
