All wiring is tight and in good condition. I cleaned the flame sensor. The heat exchanger is in good condition. I completed a complimentary refrigerant leak search on the system. No leaks found at this time. The ductwork is dirty. When I was inspecting the furnace I noticed a little bit of water under the water heater. The relief valve is working properly and is dry. I found water inside of the heater behind the outer casing. The holding tank has a small leak. I prepared a quote for replacement after speaking to the customer and showing them the issue.
Upon my arrival, the customer informed me of a few things that he wanted to happen. He informed me that he knew that the unit was old and that he was not interested in replacing the system at all. He said that the system had a 20 year warranty on the heat exchanger and that is what he wanted to be replaced. The customer was also not interested in any membership stating that it was not worth it in his opinion. I did confirm that the heat exchanger is cracked. The system is 19 years old and the heat exchanger is still under warranty. The option for replacing the heat exchanger is valid at this time but the customer wants to wait and see how long it will be until the heat exchanger is available. I also found the evaporator coil leaking refrigerant it is R 22 refrigerant and non-repairable but the customer is not worried about this at all at this time.
During my inspection today, I found multiple things I needed to bring to the customers attention. The first issue was the one that she brought to my attention and the reason we got called out here. There was water on the floor that was being created by the furnace. I found that one of the 2 inch couplings on the 2 inch PVC exhaust pipe for the furnace is not sealed properly. The glue has broken apart and is no longer creating the seal. This lack of seal is allowing water to drip from the underside of the coupling and onto the ground. The second issue I found is the gas pressures on the system or not where they are supposed to be. The manufacturer states that they want no more than 3.5 inches of water column on the furnace. The furnace is putting out 3.72 inches of water column. This did fail my inspection. The third issue that I found was that the drain lines for the system, including the one for the air conditioner, and the ones on the furnace need to be cleaned and cleared. The filt
All wiring is tight and in good condition. We spoke about the filtration on the system. The filter they are using is a good filter for the system. I prepared some options for the system, one of which is a uvphotomax that we spoke about. The refrigerant pressures are in correct range per manufacturer specifications. I completed our check sheet and emailed it to the customer. The system is working properly at this time. The customer had a work meeting come up that he needs to attend. I emailed the quotes to the customer for review.
Arrived at the customer’s residence and was lead to indoor unit, a rigorous inspection followed and the unit was found to be operating correctly. All wires were secure and the blower wheel clean. The unit did not have an easy trap or a proper size filter and both items where brought to the attention of the homeowner. The outdoor unit also checked out perfectly aside from some debris in the coil. As part of the membership the unit was professionally cleaned and everything is good to go.
I found the condensate drain clogged with algae buildup making the evaporator drain pan overflow. I cleared the drain and flushed. All water safeties are working properly at this time. I rinsed the condenser coil. The refrigerant pressures are in correct range per manufacturer specifications. The system is working properly at this time.

Upon inspection found heat exchanger cracked with high levels of carbon monoxide as much as 156PPMs . Per AGA ( American gas association ) the only two options given to fix this issue are replacement of the heat exchanger or replacement of the furnace. Also found gas pressures not regulated per manufacturer specs at manifold pressures is 4.00inWC , Manufacturer requirements are 3.0-3.8 max at manifold. Upon further inspection found p trap without overflow safety, no secondary overflow safety as well as the drain line installed incorrectly per manufacturer specs . Build and presented estimate to customer, customer accepted estimate for the heat exchanger replacement at this time.
Installed 2 surge protectors . Cycled system for proper operation both units and surge protectors are operating properly at this time.
Upon initial inspection found low voltage wiring at circuit board AHU loose due to the screws not being tight . Retighten all screws at board. Opened two small holes on supply and returned duct to test static pressure. Found both supply duct dampers closed to 60% and 45% affecting static pressure also 2 supply vents in the living room blocked by large sofa due to sofa feet height 2 1/2 inch tall from carpet to bottom of sofa. Customer moved sofa for air balance . Found 1 closed vent in bedroom , opened vent to perform air balanced . Adjusted blower speed for static pressure and CFM’s requirements . While inspecting the outdoor unit found: Disconnect not sealed at all Line set wall penetration not sealed at all Applied clear Silicone to disconnect, disconnect is now sealed properly. Applied thumb gum to wall penetration, wall penetration is sealed properly. During the inspection of the HP unit found: Loose contactor screws at L1,L2/T1,T2. Tighten all 4 screws for the high voltage
The evaporator coil is clean and free of debris. The blower amps are 10.8 in correct range per manufacturer specifications but close to the max operating amps of 11.1. The 10 uf run capacitor is in correct range per manufacturer specifications. Recommend an ez trap for the primary water safety. The condenser coil is dirty. The 70+7.5 run capacitor is shorted on the compressor side. The system is out of warranty. I quoted a turbo capacitor for replacement. The customer signed for the repair. I installed a new turbo 200 capacitor set to 70/7.5. I turned the system on. The compressor amps are 9.89 in correct range per manufacturer specifications. The condenser fan amps are .93 in correct range per manufacturer specifications. The refrigerant pressures are 330/110 in correct range per manufacturer specifications but the condenser coil is dirty causing the pressures to be inaccurate. The system is working properly at this time. I received permission and cleaned the condenser coil. The refr
