Great job

2nd tech to work on HVAC outage, was fixed however a bit of rainwater in the shorted the system. Quick service! Charles explained the remaining issue, which sounds as if it would have been hard to diagnose prior to the rain storm. Thank you!

Found the system with no refrigerant. I put minimal pressure into the system (50psig). I checked the indoor coil and the outdoor. I determined the leak is in the outdoor unit in the aluminum coil. The coil either needs to be replaced or the whole outdoor needs to be replaced. The customer stated that when it would run in heat, it would turn into a large block of ice. This tells me the defrost cycle is not working properly. I advised the customer that complete outdoor replacement would be a good decision.

Installed correct size breaker for equipment. Tested unit heat. Everything else tested in range. Talk to client about cleaning outdoor equipment to help maintain overall performance. Unit heating on departure

Arrived to downstairs package unit not heating properly. She first noticed issue Sunday morning. This morning entire outdoor unit was unresponsive. I immediately began to test the voltage to the unit and found it to have none. I found the outdoor disconnect to have completely melted and not making the proper connection to power the unit. I turned off power at the indoor electric panel and showed our client what had happened. She was aware that this issue was present from our last visit in June. The disconnect box needs to be replaced and I highly recommend a surge protector to help prevent this from happening in the future. Our client agreed to repairs but is unable to pay for it all. The amount is too low to finance and we will collect entire repair amount once work is completed. We need a 30 amp breaker in the disconnect to finish the repair.

I arrived at our clients home unit not cooling properly. I first began inside and found the filters to be extremely dirty. Our client informed me that it had been at least 6 months since last filter replacement. We immediately proceeded to replace filters. In the attic I visually inspected the indoor coil that was replaced in July of last year. I did not see any signs of refrigerant leak. I did find the blower motor to be rusted and have growth on it. I proceeded outside and placed the heat pump to heat the home. While testing the electrical components I found the capacitor to be below manufacture specifications and the defrost control board with a visibly burnt resistor. The unit has a start limit of 109 and it was reading 125! I showed these items to our client and we discussed how airflow restriction, due to not changing the filters, causes all the components to run harder and pull more energy from the home. We discussed options for repairs and protection of his equipment. He decl

I arrived at our client home for a single system heat maintenance inspection. Our client has not changed the filter this season and she will be going out to purchase a 14*25*1 filter for her unit. I proceeded to clean the flame sensor, pressure switch port and furnace cabinet today. Once cleaned I tested the inducer and blower motors to ensure they are in manufacture specifications. Both passed today. I ensured the unit had proper temp rise and our client had no other questions or concerns at this time. Unit is running properly on departure.

Customer is concerned about a smell on the system that services the hallway and most of the bedroom. The customer stated that there is a smell and wanted duct cleaning done. The system is a Lennox from 2020 with new plenums. All of the duct work is hard pipe besides pigtails from the plenums to the hard pipe. I stated if the duct cleaning does not fully resolve the issue then we can look at doing a biocide treatment on the evaporator coil. I provided pricing for cleaning all the systems and an ApcoX on the system with smells.

Performed single system heating maintenance. I checked amps, capacitor, filter, refrigerant, electrical, safeties, and cleanliness. The system is performing to manufacture specifications but I do have some recommendations. Recommendations 1. The system is beginning to have growth formations in the airhandler. It is advised to clean the growth and install a u/v light to combat the growth before it gets out of control. 2. The system has some debris in the primary pan. I fear that the system will become clogged come cooling season. I recommend adding an algae stick to treat the drain to fight against clogging.

A spring and fall VIP maintenance agreement has been added for 08–2026. Performed fall maintenance service unit is operating as it should. It is a 2021 Trane heat pump. Located in the attic has an April air 213 filter with a spare filter up in the attic for your next visit. Unit is level and draining properly did notice a buildup of debris on return ducts. Recommended a light duct cleaning as well as an ultraviolet filtration system to help keep bacteria and dust particles entering the home through the system, as well as recommended a pantry man for spring and summer months to help. Keep the drain pan draining without clogging or backing. Performed a light rinse on condenser to help. Keep dust particles from accumulating on train specific coils. Button of the unit replaced filter for departure no further recommendations at this time.

Perform system maintenance on 2021 upflow in the utility closet, unit is operating as it should at this time recommended replacing filter. Homeowner said he has some on order. Utility closet there is a 12 inch round duck going from the utility room to the garage and an 8 foot span of pipe. Quoted price for ceiling off 12 inch round duck as well as removal. Everything is working as it should at this time.

Arrived to unit not heating properly. I first ensured unit had zero error codes on the thermostat. I then proceeded to open the unit and found multiple burnt wires directly connected to the electric heat kit. I removed the heat kit and inspected it to ensure the coils were not compromised. I then proceeded to replaced a damaged contactor and repair the bad wires. Once completed I replaced the heat kit back and tested to ensure it was heating properly. The unit was pushing 98° on departure. We are scheduled to return to actually preform a maintenance visit on a different visit. I spoke with the homeowners father and he will relay the information to his son.

Arrived at client home for a single system maintenance inspection. Our client provided a new filter to be replaced today. Once replaced I proceeded to test and inspect the furnace. I tested the fire shutoff safeties and cleaned the flame sensor and pressure switch port. I also did a courtesy bubble test to make sure the gas line did not have leaks. Everything passed inspection today. I did find the entire attic to be low on insulation and brought this to our client attention. He is aware that it is low and wanted to discuss it over with his wife. We also discussed actual filter size for the filter he is purchasing. The unit is running properly and ready for remainder of winter.

System is a 2011 TRANE Hyperion heat pump. The EEV board is throwing a code for a coil sensor being out of range. I tried to bypass to see if it would run and it will not. I provided pricing to replace both sensors inside of the coil.

Performed 2 system heating maintenance. Checked amps, capacitors,cfilters, refrigerant, electrical, safeties, and cleanliness. Systems are heating to manufacture specifications. Recommendations 1. The main house unit has growth inside of the cabinet. I recommend adding a u/v light and cleaning it out to better the air quality. 2. The main house unit has a bunch of build up on the blower wheel. This reduces efficiency and adds strain to the motor. 3. The guest building has a brand new system but will become subject to growth also. I recommend adding a u/v light to deal with the issue before it happens.

Performed single system heating maintenance. Checked amps, safeties, electrical, drains, and cleanliness. System is performing to manufacture specifications. Recommendations 1. I noticed that the bulb was burnt out on the reme halo. I provided pricing to replace it.

Installed board and flame sensor and the system still wouldn’t run. I removed the parts that were installed. After further investigation, I found corrosion in the wiring harness and 2 rollouts where the reset switch wouldn’t stay in. Customer interested in replacement and paying by cash/check. Emailed estimate.

Performed single system heating maintenance. Checked amps, filter, refrigerant, flame sensor, drains, igniter, safeties, and cleanliness. System is performing to manufacture specifications. Recommendations 1. Due to the amount of pets and dust content of the home, I am recommending that a Apco-x u/v light gets installed to help combat the pet dander. 2. I recommend adding a surge protector to the outdoor system to give protection over the fan motor, compressor, and various control boards inside of the outdoor system.
Shelby S.
System shuts down with no fault code but has constant voltage on the flame sensor even without flame. System needs control board and flame sensor .

Found a giant hole in the roof due to a missing whirlybird. Customer would also like Jesse to come back out to price a mini split and other solutions for the garage. No preference on date or time.
Shelby S.
I am too big to access the attic space to diagnose the issue. From the information I gathered from the tenet, it does sound like the ecm control module is back. We need to return to confirm and price the repair. Tenent said she would be available again on Dec 2nd.

Upon arrival, checked out Single stage gas furnace for fall maintenance. Everything working as it should capacitor, blower motor, Inducer draft motor, all electrical components including, flame sensor, Pressure switches, checked amp draw on remaining electrical components everything operating as it should. as a courtesy Visual check on condensing unit noticed debris buildup around condensing coil notified homeowner both agreed it needs to be cleaned. as the weather is cooler in our fall and winter months, she agreed to have the condenser chemical washed before the spring added estimate as reminder.
Jesse V.
Performed visual inspection of condensing unit and found the system off with no signs of system failure. I continued to dismantle the condenser in an attempt to find an error code on the system. The LED lights had indicated normal operation and no signs of failure. We performed a hard reset by powering down the system for 5 minutes and reset power. The unit turned back on and started to cool the house on all levels. Homeowner verified that all mini split heads were functional and cooling designated areas. I also showed the homeowner step by step how to manually reset his system in cases of emergency and to call the office if problems continue. No further issues at this time.
Jerad L.
Came out for no cool. Upon arrival checked filters and coil on outside unit. Coil is clean, filter could be cleaned. Checked temp split and getting 43 degrees out of vent. Let customer know if issues persist to let us know but system is cooling at this time. Thank you for your time.
