White shield club AC maintenance. Joe(JC)Ritchal. 09/13/2024 Performed full system evaluation and safety inspection. I arrived to perform the customer’s annual AC maintenance. The customer didn’t have any questions and said that everything was running well. I then washed out the condenser and inspected it. I found that the capacitor was getting weak. The capacitor was at 40 and was rated for 45. The system is under a full warranty. I replaced it and reinspected it. I then checked the furnace and coil. The heat exchanger was in good shape and the heating components were in good shape and running well. I also replaced the air cleaner media. The system is operating correctly at this time.

11SEP2024 Jason Brown Arrived for non club no cool. Spoke with Staff about the systems performance. It’s the back right unit, it stopped cooling for awhile and I changed the filter, then it came back on. Inspected evap and furnace. Found filter brand new, evap clean, blower wheel, motor, and cap all in good condition. Inspected AC. Found run cap shorted on the fan side and compressor bypassing. Spoke with Lisa on the phone, and discussed repair options. We decided to move forward with a new motor and capacitor, as well as sign up for a 3 system blue maintenance contract. With approval I disconnected the power to the AC. Removed fan shroud and separated motor from blades. I installed the new motor and reinstalled the shroud. I then wired in the new motor for 1/4hp and cycled cooling. Verified amps and pressures. System is cooling at this time.

Blue shield club AC maintenance. Joe(JC)R. 09/10/2024 Performed full system evaluation and safety inspection. I arrived to perform the customer’s annual AC maintenance. The customer want to make sure that the filters were included with the maintenance. I told him that standard sizes were included. I the washed out the condenser then inspected it. The condenser was in good shape and running well. I then checked the furnace and evaporator coil. I found that the blower capacitor was starting to get weak. It was at 4.3MFD out of 5. This is causing extra stress for the motor and wear it out prematurely. I also replaced the filters for the customer. The customer will pass on the estimate for the repair to the property management company.

Came out to perform preventative maintenance on AC systems. Discussed with customer about maintenance being provided today, filters, and any issues they’ve had with the units. Customer stated they change the filters regularly and that they haven’t had issues with the units, just seems like longer run times. I started my inspection with the equipment in the attic. Inspected the ductwork, blower assemblies, motors, evaporator coils, drains, and overall condition. Washed condenser coils thoroughly. Inspected the condenser coils, compressors, fan motors, capacitors, contactors, and electrical wiring. Cycled units on and checked amps, temperatures and pressures. Found downstairs unit has a contactor that is starting to fail and I recommended replacement before it does. Customer approved replacement. I replaced the contactor on the system. Rechecked system operation. Both units are cooling properly at this time. Made customer aware that the longer run times were most likely due to the units

No cool. Joe(JC)R. 09/06/2024 I arrived to a call where the customer said the system was running but wasn’t cooling. I found that the indoor equipment was running well but the compressor capacitor had failed. I received permission from the customer to replace the capacitor. I replaced and reinspected the condenser. The system is running well but it is 21 years old. The customer wants an estimate for a new system.
ISAAC J.
Coil was missing a drain plug on the other primary drain of the coil. Added a plug and cleaned up water in emergency drain pan. Cycled system on and rechecked operation. No other issues present with the unit.

Jake Kring. 09-05-2024. I arrived for a club member summer tune up. I inspected the system located in the attic and found the evaporator coil to be extremely rusted and the blower motor to be leaking oil from the bearings. The capacitor for the blower motor is weak and under the manufacturer recommended MFD readings. I checked the condenser and found the coils to be clean and the refrigerant charge to be within manufacturers recommended range. I did find the contactor to be pitted and the points to be worn down. The condenser fan blade is unbalanced and is causing the motor to vibrate and this can cause the bearings to wear out and put extra stress on the system. I discussed all issues with the homeowner and we briefly discussed replacing the system possibly early next year or when the system breaks down next. This system is running at this time but has multiple issues that can cause the system to stop cooling with any one of the breakdowns.

Jake Kring. 09-05-2024. I arrived for a blue club membership tune up. I inspected the system and found the u it to be completely stopped up with grass growing into the condenser. I first cut the grass free from the condenser and disassembled the system to clean the unit. Once I got the system clean I reassembled the system and cycled the system on. I found the capacitor to be weak and in need of replacement. I checked the amp draws and all electrical components and found the, to be running fine but to have a good amount of wear on all parts. The contactor is pitted and the points are worn down completely. I replaced the filter and inflated the homeowner of the issues and we decided to let it run and pay a service fee when the parts fail. The system is running at this time but will benefit from replacing the parts to get this system running to the best it can. With the parts weak this can cause extra stress on the system and could potentially cause more to fail if the weak parts complet

04SEP2024 Jason Brown Arrived for 3 system summer tune up. Spoke with Lewis about the systems performance. They’re all working well, the ACs are getting particularly dirty if you don’t mind cleaning all the leaves out. Inspected all three systems. Washed condenser coils, and checked all amps and pressures. Homeowner already replaced the filters. Found all systems working properly. Work declined: Warranty Run capacitor for the 2019 system.
Jeremiah F.
Estimate to replace the existing system with a 3 ton Carrier AC and Coil 09/03/2024 JeremiahF Arrived on site and called homeowner to go over scope of today’s service. Recovered existing refrigerant and uninstalled existing equipment. Flushed line set. Installed new equipment. Sealed indoor unit with metal tape and anchored with zip screws. Pressure checked system at 230psi with dry nitrogen and passed pressure check. Pulled vacuum down to 210 microns and passed vacuum decay. Added 1lb of refrigerant to system to get unit to 8/8 degrees of subcooling. System is operating properly at this time. While up in the attic I detected a gas smell. I bubbled the gas line and found the leak coming from the top compression nut on the track pipe leading into the shutoff. Nut was fully tightened so I took a picture of the leak and informed the homeowner of the issue.

Two systems silver club AC maintenance. Joe(JC)R. 09/03/2024 Performed full system evaluation and safety inspection. I arrived to perform the customer’s annual AC maintenance. The customer didn’t have any questions and said that everything was running well. I then washed out both condensers and inspected them. The upstairs condenser was in good shape but the downstairs condenser had a weak capacitor. The compressor side was at 22MFD and is rated for 45. And the fan side was at 1.7 and is rated for 5. I then checked the furnace’s and coils. The upstairs furnace and coil were both in good shape and running well. The downstairs stairs unit’s drain pan was half full of water and the drain was only slowly draining water. I received permission from the customer to clear the drain. I cut the line and cleared it and made sure the primary drain was draining well. I then cleared the backup drain. Both systems are in good shape and without any issues. The customer wants to wait on the capacitor

Jake Kring. 08-31-2024. I arrived for a club member summer tune up. I inspected the indoor air handler and found the filter to be dirty and the homeowner provided a replacement filter. I replaced the filter and inspected the evaporator coil and blower motor. I found the motor to be running well and the evaporator coil to be clean. I found the insulation on the blower door to be coming apart and I reinforced the insulation with tape to the blower door and cleaned the system up. We discussed the duct work and that she has some water in the ducts at times and I recommended to contact thunder ducts to see if they can seal the duct work. I also flushed the drain line out free from the debris that were holding in the p-trap. I then inspected the condenser and found the turbo capacitor and contactor to still be in good condition but the system was dirty. I cleaned the system free from all debris and left the system running per the homeowners thermostat settings.

ISAAC J.
Gave estimate for replacement of an AC and evaporator coil.
ISAAC J.
Came out to call to replace an evaporator coil. Went to pump down the unit and found the suction valve gasket is bad and started leaking refrigerant. I ended up back seating it to keep it from leaking and then discussed with customer about her options now moving forward. After going over repair vs replacement, customer chose to go the route of replacing the AC and the evaporator coil to negate any other issues with the unit. Told her I would send her the estimate and we would have it set up for next Tuesday.

Jake Kring. 08-28-2024. I arrived for a silver member tune up on a rental property. I first inspected the filter and found it in need of replacement. With the debris on the filter and it being a hard floor and a local return at the base of the Goodman air handler I recommend to replace the filter every two months. I checked the evaporator coil and found it to be clean and the blower wheel to be rusting but clean. I then checked the heat pump and found the coil to be completely stopped up. I cycled the system off and disassembled the condenser. I cleaned the single wall coil free from all debris and then cleaned the hail guards free from debris. I then reassembled the system and cleaned the system again. I then cycled the system back on and checked the electrical components. I found the capacitor to be reading well in normal rang and the contactor to be clean with the points of the contactor to not have any pitting or charging at this time. I checked the systems refrigerant charge and f

26AUG2024 Jason Brown Arrived for blue club summer tune up service. Spoke with homeowner about the systems performance. It’s been working well, but I noticed that sometimes it will be a little warmer than the setpoint. I keep it around 68 in the day and lower at night. I haven’t replaced the filters this season yet. Replaced 14x24 filters. Cycled cooling, inspected evap and blower. Motor and wheel in good condition, evap clean. Inspected ductwork and connections, moved outside. Washed condenser coils, checked all amps and capacitors, verify ohms at contactor. Found return undersized to equipment, and bearings seems to have a little wear. Spoke with homeowner about my findings, we decided to keep an eye on the ACs fan, and leave the ductwork. System is cooling at this time.

I spoke with the tenant and found that they needed an inspection on the furnace and ac system to keep their warranty up to date on the new home. I first inspected the evaporator coil. The coil is clean and the drain line is clear with no buildup in the primary drain pan. I then inspected the condenser and found the capacitor to be a 40/5 capacitor that is reading 40/4.9 at this time. The capacitor is not recommended to read below 37.6/4.7. The amp draw in the condenser fan motor and compressor are under the manufacturer recommended range of 11.7 for the compressor and 0.60 for the condenser fan motor. I checked the systems refrigerant charge and found the system to be running at 10.8 and the system calls for 10.0 deg of subcooling. The subcooling is aloud to be within +/- 2 deg giving

Came out to call for a system not cooling properly again. Customer stated that we were out less than two weeks ago for the same problem. Tenant let me know that it’s doing the same thing it was the first time, and hasn’t really worked quite right since she moved in. I went ahead and checked system over and found unit low on refrigerant again. I checked the leak we fixed at the AC and found no issues there. Did a leak search on the evaporator coil and found a leak in the coil. Discussed with customer about the current issue and why it wasn’t found the first time around. I apologized to customer about the inconvenience and told her I would work with her on getting it fixed properly. As of right now I added refrigerant to system to get her tenant cooling through the weekend and I’ll get availability of installation of a new coil Monday.
