I arrived at our clients home for home for the upstairs unit not cooling properly. The indoor unit was on and running but the outdoor equipment was not coming on. I immediately proceeded outside and began inspecting and testing the condenser unit. I found the capacitor to have failed completely. I ensured the unit did have standing Freon pressures. I presented my finding to our client and he elected to replace the capacitor and join our maintenance plan. Because something like this could have been caught before failure. Once I replaced the capacitor I further tested and inspected the system operations. I found the indoor air filter to be extremely dirty and discussed the importance of replacing the filter. The unit has the option to receive a 20*25*4 filter that would last longer. Currently the unit is without a filter but our clients will install a new one immediately. The system is cooling with a 18° drop and running properly on departure. The new capacitor does come with a 5 yr

I arrived to our clients home for home for concern the unit was not keeping up and potentially frozen after our recent visit. I proceeded into the attic and found a single system zoned with only the upstairs calling for cool. Scott explained to me a little how he ran the unit and he desired set points for upstairs and downstairs zones. He felt like last night the evaporator coil was frozen and shut it off but turned it on again this morning. I connected my gauges and immediately was reading some abnormal pressures with only the upstairs system calling. I went back into the attic and found the bypass damper module with its standard resistance. I then called for the downstairs to cool and checked my pressures again they were testing perfectly and I was getting a 20° drop from the indoor unit with 55° air being supplied into the home. Scott and I then began to have a discussion of how his unit and duct work was the real issue. The upstairs zone and the restriction on the bypass damper

- Met homeowner at the door. Walked me to the thermostat showed me that it was blank and that it was intermittently coming off and on. Accessed indoor equipment the garage immediately noticed auxiliary/emergency drain pan had retained water tripping the Water detection safety device/float switch. Homeowner has 10 year parts and labor warranty. Dispatch has also confirmed to waive $45 service charge fee in light of it being drain line related. Determined that primary condensate drain line ran to guest bath room sink. Today sink draining test And the sink was draining properly. Restriction between HVAC equipment and P-trap underneath sink. Homeowner provided tile to cover sink to prevent blowback. - Used nitrogen tank to clear out primary condensate drain line. Vacuumed out retained water in auxiliary emergency drain pan. Remove homeowner’s towel from the sink and performed an additional sink drain test. Sink is draining properly after clearing drain line out. - System became functional

Preformed cooling maintenance. Tested all electrical components inside and outside. Tested start amps and run amps on compressor and fan motors. Noticed when we tested the contactor it was failing with high ohms, customer elected to have contactor replace. Customer also noticed a loud noise coming from the outside unit. We found that some screws were loose along with the suction line touching the unit. Tightened all screws and moved suction line off unit. Provided estimates for a blower wheel cleaning. Upon departure unit was cooling and in working condition.

11 supply vents 2 return vents Additional service of cleaning the return plenum box included

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. Inspected drain lines and treated to prevent blockages 15. Washed condenser unit to promote heat exchange Noticed debris on evaporator coil. Recommend cleaning to improve indoor air quality as well as reduce stress on the system. Filter was not available to change at this time. Stressed to customer the importance of changing the filter and that it should be changed as soon as possible. Recommended potentially changing filters m

Preformed cooling maintenance. Tested all electrical components on start and run amps of the compressor and fan motors. Upon inspection of the outside electrical components the capacitor on the compressor side was failing 41/45. All other components tested within manufacture specifications. We did notice that the levels for the refrigerant were low after placing our gauges on the system and determined there was a leak happening. No signs of the leak being on the outside unit. Offered estimates for warranty evaporator coil and a new capacitor. Client went with replacement of the coil under warranty. Tried to locate coil. Coil is on back order with Johnson supply.

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. Inspected drain lines and treated to prevent blockages 15. Washed condenser unit to promote heat exchange Customer brought to our attention that one of the dampers was not behaving properly and would not close completely. Will need to open duct and adjust set screw to ensure damper is properly set. Additionally we will need to reseal the duct after adjustments. Duct was already loose and leaking air. Measured high start amps on

Performed a 3 (5 heads) mini split systems maintenance… All safeties were checked, return filters/ condenser units were washed, temperature differential was measured,, there are 2 evaporator coils that need to be cleaned, ( we put a red sticker on the bottom, on those 2 temperature differential was 16 degrees split differential while on the rest was 20,,we highly recommend to be cleaned as soon as for better performance, drain lines are cleared, , found no more issues/ concerns at this time.

Preformed cooling maintenance. Tested all electrical components on the inside and outside start and run amps on fans annd compressor motors. All tested within manufacture specifications. The client did mention that the master bedroom was a little warmer than the rest of the house, adjusted dampers to regulate airflow to the master bedroom. Also noticed the attic could use more insulation near the master bedroom supply. Upon further inspection of the inside unit we noticed the drain pan to have rust spots and calcium deposits on the underside of the unit. Upon further inspection of the outside unit we found the contactor to be reading high and is pitted on the contacts. We provided estimates for a new contactor, drain pan and insulation.
