3/16/26. Found rooftop unit for “clean room” not working at all. Gave rooftop a call for heat and went up on the roof. Found inducer motor running but hot surface igniter not glowing. Found 130 v going to ingniter. Measured resistance to hsi and it was 300 ohms. Reading should be between 40 to 90 ohms. This igniter is very specific to this rooftop. Also found that the igniter does not make a great seal at the combustion chamber. This could cause a gas smell. When new igniter is installed will need to use high temperature silicone around igniter to seal better. Gas furnace is down at this time. Shut off disconnect.

Issue was Nest thermostat displaying No power to R. The system does not have any low voltage safteties that would break power to the R. 120V switch was ON. There is no emergency switch. There was no led on board. I took furnace off and checked the 3A fuse and it was intact (no shorts) I bypass furnace door switch and checked for 24V had 28v Good. The furnace started shortly thereafter. What I presume happened is the 120V door switch was open enough caused by vibration of the door overtime which broke 120V power to the system. I also checked the wiring of the furnace switch/receptacle 4x4 box. I found the furnace stranded “Hot” conductor around the terminal. A solid wire is preferred here so I replaced and wire nutted. There are no other indicators of causes of loss of 24V to the thermostat. There is only 9” between blower compartment door and backside of 2x4 wood frame wall. Make sure you tighten the left side screw down fully after putting furnace back together. System ran for

I arrived for a no heat water in the secondary pan . Found the wet switch was tripped causing the furnace to shut down. I reset the safety switch and let the furnace run for a bit to see where the water was coming from. Eventually found the water was leaking from the humidifier and running down the 1/2 tubing into the secondary pan. I quoted out for a humidifier service and replacing his 1/2 inch clear tubing. The customer approved the work. I started with cleaning the humidifier and replacing the humidifier water panel #35 , and cleaned out the frame that holds the panel. I then removed the clogged 1/2 tubing and replaced with new. I turned the system back on and began testing the humidifier and the furnace operation. No more leaks. Everything is back up and running again. I collected for my diagnostics and collected for humidifier service and the 1/2 tubing repair. I also left an estimate for the customer for a contract for 189.00 for them to review. Total collected for tonight $420

3/13/26. Found breakers turned off on air handler when I arrived. Explained to homeowner that on an American standard system when the breakers show green that means it’s safe to work on ( which is the way they were when I arrived). Red means caution. Turned breakers on at air handler and tested operation. After resetting found 2019 heat pump locked out on defrost board on a code (2) shorted or out of range coil sensor. Tested coil sensor and found it to be 924 ohms, it should be around 33,000 ohms at 33 degrees. Recommended replacement of defrost board and sensors. Called distributor got pricing on parts. Homeowner paid in full for repair.

Luis 3-9-26 customer called in for noise coming from water pipes feeding bathroom on second floor. We installed recirculating system. Customer stated he hears noise every 30 minutes. I test pump while the pump was running no noise present. Check water flow on bathroom ok, customer gets hot water instantly, I did not hear any noise from pipes. I explained to customer is probably when pump starts running and is circulating water from hot side over to cold side. Expansion and contraction. It could also be that pipe clamps came loose and it making pipes vibrate. No charge warranty.

Found line set not getting hot when I arrived. Went out to check 454B refrigerant pressures and found head side was 206 true suction pressure was zero. Found discharge service line king valve was shut and suction valve was open correctly. Opened up high side valve and checked refrigerant pressures. Compressor seems to be OK. Checked all electro connections and components. Check thermostat settings. Checked wiring. Make sure all penetrations are sealed. 3/8 vinyl does go outside but humidifier homeowner does not use.

Upon arrival found unit heat pump low on charge . Added 3.5 lbs to system to bring to standard . Set thermostat dip switch setting to correct ranges. Any problems moving forward should be unrelated to us and chargeable

3/4/26. Found that the room where they had the smell in was all the way on the other side of the roof about 400 feet from the access. Explained to owner that the 1st step is to call peco gas in this situation. They would like us to call them tomorrow when you can see on the roof. 3/5/26 Returned after peco was out. They shut down 5 systems. Took photos of the tags that were given to business office. Found after taking to the maintenance guy on staff he was using a gas leak detector at the furnace exhaust. This should be done by a combustion analyzer. Used combustion analyzer on system in question. Also used soap bubbles to check for leaks. Did not find any gas leaks. Examined heat exchanger and blower belt, all looked ok. Did not find any issues at this time. Smell may have came from exhaust hood on roof , smell coming into economiser possibly. Gas rooftop is working properly at time of service.

Fully assessed 2006 Goodman heat pump not working properly. Found system low on charge. System is r-22. Pressures were 150/41. Also found evaporator coil rusted and corroded and covered in dirt and lint. Coil in not able to be cleaned without removal. Also found reversing valve getting stuck and not fully switching over after coming out of defrost. At this point only logical option is to replace heat pump system. They are going to talk with management.
