Performed AC diagnostic on 1996 unit. Upon arrival client stated that system was working about 15 minutes ago and he almost canceled and then it stopped working again luckily I was in front. They’ve never done any repairs or had any issues in the past with the system. Upon arrival I found the condenser fan motor was not spinning but the compressor was on on. Duel secondary motor control was good indicating that the fan motor was defective. Ultimately client would like to do the fan motor repair and sign up on a maintenance plan to keep their system at a stand. Informed them that anything done to the system is considered a Band-Aid due to it being past its design life at this time. Install condenser fan motor and cleaned condenser coil at this time. System is operational in cooling with a 21° split.

Performed AC Diagnostic on 2005 Lennox system. Upon arrival client stated the outdoor fan motor is no longer spinning and prior to this CAS technician recommended that the fan motors were swapped out due to oil leakage and over amping. During the inspection I found multiple points of concerns that were addressed. 3.5 ton condenser- 1. Duel secondary motor control was dead on hermetic and fan side terminal. This part mostly become defective Due to an over amping component, which would be the compressor and the fan. 2. Both outdoor condensing fan motor have significant oil leakage and are beginning to over amping at this time 3. Power disconnect is not supplied with fuses or surge protection 4.

Performed AC Diagnostic on 2006 Lennox condensing unit. Upon my arrival clients are renting and Found that the system was not working on Friday due to the breaker consistently tripping every time they try to turn it on. Yesterday they had a friend come by and try to see what was wrong with it but he also could not figure it out. During the inspection I found 2 major Terminal faults with the system. 1. Inspected outdoor unit for downstairs and isolated the compressor from the circuit. Tested continuity on hot leg and common wire of the system and found that it was grounded out unfortunately. With a ground it out compressor this will instantly pop the breaker due to the windings Becoming no good. In this situation they’re only really two options either finding a new R22 compressor, or System replacement options 2. Before departure Downstairs had a vapor smoke coming out of the supply vents. Investigated unit in the attic and opened up the evaporator coil to find out the system has spr

Performed AC maintenance on a Amanda system. Units cooling temperature split is 16 degrees. Thermostat was throwing signs of update issues and waiting on equipment signs when I was working in the equipment. This concerned the customer as it never has happened before. Came to the conclusion it just has a long delay. Filter is clean. Scroll wheel is dirty. Indoor amperage are ok. Indoor start component is ok. Outdoor unit was heavily caked with leaves and pollen. This was chemically washed today. Start components are showing signs of failure. Battery cap was changed today. At the end of the appointment customer stated it does not feel any cooler and is not cooling. Temperature split was at 18 at the end of appointment. System is running.

Clustered issuers have been happening he took a look to see if he could fix himself but he just was able to get it to Wooster on and off manually as he would have to pull the disconnect off and on and unplug the outlet on and off. Advised that may work but is not good or should operate like that. Thermostat was operational due to batteries. Inspected out door unit and found primary starter completely burnt up and almost shut due to High voltage. Client even replaced secondary capacitor and still would not work he went to replacing the fan motor and replaced it and would still have to manually push motor fan to get motor to turn on.

Technician arrived on site and found a crack in the primary condensate pan. Gave homeowner options to replace the pan or to do a temporary repair until the system can be replaced. The temporary repair includes adding a secondary pan, condensate pump, and a condensate rework. Replacing the primary pan is correct option for this repair. Homeowner is aware that biological growth can happen in the secondary pan if it isn’t fully draining.

Tech arrived on site and did ac tune up. Condenser had been rebuilt. All electrical start components had been replaced and checked out. Fan motor was amping at max. While the unit was running. It tripped on the low pressure switch multiple times. Pressures confirmed the switch was good. After about the 4th time the unit pressures stabilized. Had an 18 degree split. Super heat was a little High. Indoor unit was okay. Blower had been replaced. Possibly the control board as well. Cap was new. Heating side looked old. Did not test this visit. Recommend budgeting for replacement soon as the unit is getting to replacement age.
