Performed cooling seasonal safety check. I tested all electrical components on the inside unit along with cleanliness. All electrical components were testing within manufacturer. I found that he blower wheel and evaporator coil could both benefit from having a deep cleaning done. I proceeded outside where I tested all electrical components on the outside unit. All tested within manufacturer specifications. The start amps on the compressor were starting high at over 100 amps. By adding a hard start kit it can help assist those high start up amps to come down to almost half. I provided estimates to have all concerns addressed at the time of inspection. Unit was cooling upon departure.

Preformed duct cleaning estimate. I thoroughly evaluated the ducts and system itself. The homeowner did mention that she hasn’t had the ducts cleaned or anything for atleast 30 years of living in the home. The unit is from 2012 rheem electric system, i found that the blower wheel and housing had some growth along with dust/debris build up. Presented all picture documentation of my findings to the homeowner. I presented options for the homeowner to go over.

Preformed single system cooling maintenance on a 2021 inside and 2023 outside heat pump. I tested all electrical components on the inside unit. All tested within manufacturer specifications. I did change the filter out for the client today. 20x20x1. Treated drain line with total c. Checked for cleanliness of the mechanical parts. The blower wheel and evaporator coil could benefit from a deep cleaning. I proceeded outside to test all the electrical components on the outside unit. All tested within manufacturer specifications, however the capacitor was testing on the lower ends of the manufacture specifications range at 38.12/40 mfd. The start amps of the compressor were starting higher than 100 amps the manufacturer rating is 110 max amps on start . The unit also doesn’t have any type of surge protection on it. The unit could benefit from having a hard start kit and surge protector installed. The hard start kit will help bring down the high start amps and will help prolong the life of t

Preformed overall inspection of the smell coming from the unit. We found that the best solution for the system and homeowner is to add fresh air to the system along with adding a supply and return to the attic since it is spray foamed. Without this it is causing high humidity problems and rusting a lot of the metal out. We also talked about adding Aprilaire return box to the unit. Also we check the out door condenser fan motor. The grate had broken holding the motor and needs to be addressed. Provided estimates to customer about the solutions. Unit was heat/cooling upon departure.

Arrived on site for maintenance on 2023 Trane furnace. Performed maintenance as scheduled. 1. Visually inspected condenser coil for debris/ dirty. 2. Inspected condenser fan motor. 3. Inspected condenser fan blades. 4. Inspected/ cleaned wiring connections. 5. Tested for gas leaks 6. Tested functionality and cleaned flame sensor 7. Tested functionality and cleaned pressure switches and ports 8. Inspected / replaced return filter. 9. Inspected return plenum for debris/ dirty. 10. Inspected evaporator coil. 11. Tested functionality and visually inspected surface igniter 12. Checked blower amp draw. 13. Measured temperature differential from supply to return. 20 degrees measured. 14.Drain line tested with gallon of water for clogs and to push anything trying to solidify out Found large amount of dust in return underneath unit. It is inevitable that overtime the dust will get sucked up into the unit. It is important to get this removed because dust is the number one killer of AC systems

Upon arrival, I discovered that a burning contactor causes the transformer to lose 120v out of 240v. I received approval from the customer to replace the contactor under warranty and repair the wiring. After repairing, I tested the system to ensure it was properly heating. System is heating upon departure.

Upon arrival, I found the unit set to emergency heat. I tested the emergency heat and discovered a loss of power to one of the circuits. I went to the main panel and found the breaker off. I turned it on and the electric heat went back to performing at full capacity. I swapped it to heat pump heating and verified that it worked. With the amount of water dripping on the outdoor unit, I did not open the panel to prevent water damage to the components. System is heating in both electric and heat pump heating upon departure.

I performed a single heating maintenance on a 2020 airhandler and 2019 410A heat pump system. I checked amps, capacitors, filters, electrical, drains, and safeties. I noticed that the airhandler has bit of build up present on blower motor. I rinsed it the best I could with water. I found that the capacitor has not been changed reading 42/45 on the compressor side. The customer is aware of the capacitor and wants to change it himself. I provided pricing to address the build up on the blower wheel. Unit was heating upon departure.

With the returning of the smell, we will need to clean the evaporator coil again. Customer wants to move towards a permanent solution, but still does not want the Airscrubber. I presented a partial solution. This includes cleaning and a u/v stick. Collected service fee and will give it back once repair is selected.

Upon arrival, I checked main power supply at the disconnect. I discovered that there was not any power being supplied. Customer stated it was performing great, but it was turned off for the solar guys to work. The unit has not operated since then. I traced power back to the main breaker box. I located an unlabeled 50amp breaker in the off position. I turned it on and the mini split regained power. I tested the mini split in heating mode and yielded a fantastic temperature split. Customer had to leave to go back to work. I collected my dispatch and got signatures.

1. Visually inspected condenser coil for debris/ dirty. 2. Inspected condenser fan motor. 3. Inspected condenser fan blades. 4. Inspected/ cleaned wiring connections. 5. Tested compressor/ condenser fan motor capacitor. 6. Checked compressor amp draw. 7. Checked condenser fan motor amp draw. 8. Inspected / replaced return filter. 9. Inspected return plenum for debris/ dirty. 10. Inspected evaporator coil. 11. Inspected blower motor/ blower wheel. 12. Checked blower amp draw. 13. Measured temperature differential from supply to return. 20 degrees measured. 14. Tested capacitor and contactor (outdoor electrical) 15. Rinsed condenser unit to promote heat exchange 16. Tested emergency heat and found no issues All is well with regards to heating cycle. However, I did find that the contactor was testing very low on the condenser. This will likely need to be changed out under parts and labor warranty very soon, however, it is still testing within range, and I am unable to process a warranty

Arrived on site for heating maintenance on Gree three head mini split from 2019. Homeowner stated system was not keeping up in living room area. The other two heads were in bedrooms. I washed the filters for all three heads as well as the condensing unit outside. Upon taking a temp split, I was only getting a 10° split in heating and cooling lead me to believe there’s a problem with the refrigerant levels. I did not have the mini split adapter on hand and was unable to take refrigerant pressures at this time. I then conducted a leak test on the copper lines, condensing unit, and all three heads. It was at this point I detected a leak at the living room evaporator video included. I then check the warranty status and found that it was no longer under warranty. I then discussed with the homeowner possible options for addressing the issue. I informed the homeowner that our options are very limited since it is not under warranty and 410 a equipment has been phased out and I can no longer pu

Preformed single system heating maintenance on a 2019 gas furnace. I tested all electrical components and safeties. All tested within manufacturer specifications. I checked the inside unit for cleanliness. I did find that the blower wheel was dirty. With it being dirt it can cause drag and motor failure. I was getting a supply temperature at 112 degrees with the return at 68 degrees. I changed filter for client 16x25x1. I proceeded outside to visually inspect the outdoor unit. I did notice that the condenser coils were dirt with dirt/debris, this cause can cause issues with the unit not being able to have the proper airflow and not cool the house properly, also can lead to the coils to possibly leak. I also the unit did not have any type of dedicated surge protection. By adding surge protection to the hvac unit I can help in the events of a lightning storm, black/brown out or any type of surge in power that can cause harm to the units electrical components or unit failure. Unit was hea

I performed a single system heating maintenance The heating source is a heat pump with back up electric heat. The outdoor is from 2002 and the airhandler is from 2013. I checked amps, electrical, cleanliness, and safeties. The system has a 15kw heat kit and only using 10kw of it. I observed that the suction line does not have any insulation on it. This reduces efficiency and causes it to cost more to run. The evaporator coil is dirty on the bottom side . This will reduce the efficiency and cause operation issues. The blower wheel has growth clusters causing air equality reduction and added stress to the system. I offered surge protection, and the customer has someone that is going to install some for the HVAC system. I spoke about the liability of doing a thorough cleaning on the evaporator coil. Customer would like to wait to see how it performs when cooling season comes back around.

3 year warranty / 10,000.00 coverage if part fails to protect connected equipment. I installed the surge protector on the outdoor unit and ensured it was functional. I washed the evaporator coil thoroughly with chemicals, allowed time to soak, and rinsed it with water. We provided this cleaning to address dirty Sox syndrome and customer is aware that it will likely return, with no estimated time frame, without preventive u/v devices.

I performed a single system heating check on a 2009 Goodman gas system. I checked amps, electrical, capacitors, safeties, and cleanliness. I noticed that the inducer motor is making an odd vibrating noise. I tightened the screws and the noise remained. It seems the bearings are worn causing this vibration to occur. Bearing failure will result in the motor failing completely over time. I observed that the blower wheel has a noticeable amount of dust build up on it. This will cause the bearings to become worn at an accelerated rate resulting in the blower motor seizing up. I gave solutions to these observed issues during the time of service.

Upon arrival, I investigated the odor the customer is experiencing. I found that the evaporator coil is emitting the associated smell. I spoke with the homeowner about routes to addressing this issue. I offered the air scrubber, u/v light, evaporator cleaning, and adding supply and returns to the attic. I performed the maintenance at this time, too. I noticed that compressor is not protected with a surge protector. Customer confirmed that they have power outages at times. The compressor is starting with higher than recommended amps. 108/109. I offered a surge protector. Customer decided he only wanted estimates for surge protector, hard start, and the evaporator cleaning. The supply plenum is experiencing rust on the outside of it. With the home being spray foamed, it is advised to install supply and return grill in the attic to allow the humidity to removed.

Dryer Vent Cleaning, showed before and after pictures to client, I preformed heat maintenance on a 2023 Trane gas furnace. I tested all electrical components and safeties on the inside unit. All tested within manufacturer specifications. I proceeded to the outside unit to visually inspect. I noticed that the unit does not have any type of surge protection on the system. Provided estimate to have surge protection installed. Unit was heating upon departure.

Labor to pick up, install, and handle warranty paperwork. December 4th, 2025 I returned to install the warranty inducer motor. The noise is no longer happening and it is performing well. Also, I performed a CO test to ensure not CO was back drafting out of the flue.
Shelby S.
Upon arrival, I found that the bearings in the inducer motor are worn causing a metal on metal rubbing noise. I verified that the system has a parts warranty, but the system no longer has a labor warranty.

Upon arrival, I found the outdoor unit was in a hard lock out. The manager told me that they recently replaced the filter due to it being completely compacted. I reset the hard lock out and got the system running. I checked the amps, capacitor, and refrigerant. I determined that the unit had tripped 3 times on a low pressure switch. This resulted in a hard lock out on the outdoor unit. I did not have access to the indoor unit to further evaluate.
