Technician arrived on site and installed new s30 with smart hub. Thermostat would power on but there was still communication errors. Found that previous company had improperly wired zoning control board and wirings going to the indoor unit. Had to replace all low voltage wiring. The furnace connected and was heating. Still no cooling. Found a defective float switch that was cutting power to the outdoor unit. Bypassed it and the outdoor unit came on. Unit is now heating and cooling properly. Found no surge protection on the unit. These units are communicating systems with a total of 4 control boards. Expensive ones too. It’s strongly recommended that surge protection is installed on the equipment.

Arrived on site to perform diagnostic on 8 year old Goodman system. Homeowner states that system is not cooling and outdoor fan is not turning on. He is pretty handy and ordered and replaced the capacitor but system is still not cooling. Cycled system for cooling. Indoor unit kicks on and starts blowing air, but just warm air. Outdoor unit is completely unresponsive. Checked outdoor unit electrical and system components. Verified that capacitor was installed and wired correctly. Found that unit was recieving proper low voltage command but primary motor control was not engaging. Primary motor control is bad and needs to be replaced. With approval replaced primary motor control. Cycled system for cooling , unit kicked on and started cooling. Verified proper refrigerant charge and system is producing proper temperature split. Amp draws on compressor in range. Condenser fan motor is amping over max capacity and has started to leak oil as well. Went over full findings and recommendations wi

Performed AC diagnostic on 2002 Bryant condensing unit for upstairs. Upon arrival Larry stated that the system may have not been keeping up a temperature the last time he ran it and thought it was a bit hotter than usual. During my troubleshooting I found multiple points concerns are addressed with Larry. Upstairs- 1. System is low on R22 refrigerant 2. System Contained R22 which was completely phased out January 1, 2020. 3. Condenser fan motor has significant oil leakage coming from Bearing and can lead to failure from locking up or overheating. 4. Duel secondary motor control is weak on hermetic side terminal due to compressor using more power than needing 5. Compressor saver kit can be added to reduce start Amperage and reduce wear and tear to heart of system. 6. Power disconnect was not supply with fuses or surge protection 7. Recommend that leak dye is injected into system to help pinpoint and locate 8. System had a 15° split 9. Upstairs drain line on primary PVC was backed up wi

Performed AC diagnostic on 1989 Payne unit. Upon my diagnostic client stated that he is a renter and will be handling payment for today. He’s not sure when the system broke but realized this weekend when it wasn’t working. What I was able to find was that the outdoor condensing unit was functional but not receiving 24 V low-voltage from the furnace indoor. So I did some troubleshooting on the circuitboard inside the furnace and found multiple burn marks on Electrical Diodes and the board was an overall in very bad condition. After trying to directly jump cooling at the brains of the system there was no sign that power was making it across the circuitboard anymore. this was ultimately caused by a power outage/old equipment That made the board become defective. There is a board in stock at the supply house and I was able to pick up although Tenant was not expecting repair to be that much, So he will relay this over to the property manager and see what they want do. The system is from

Summer AC Maintenance Performed Upon arrival system is working and operational. I began my maintenance at the outdoor condenser by breaking it down and cleaning with water and coil solution removing dirt and debris. I inspected electrical components for wear and tight connections. Tested amp draws on system. Checked refrigerant pressures and charge, noted variance in subcool number, potential debris in refrigerant cycle. Upon inspection of outdoor unit I found the low voltage wiring to be broken and non insulated, potentially chewed upon by dog or rodent. I found the compressor to be pulling high amperage upon start up as well as the secondary motor control to be well below its value. Recommend a hard start kit to be added and the motor control to be replaced. I then proceeded to the indoor furnace unit. I added a filter into the system as there wasn’t one. I checked electricals ensuring tight connections. Inspected blower compartment for proper balance and dust and debris. Checked

Inspected system for operation and found system cooling properly with good temperature splits and adequate refrigerant charge. Measured the thermostat calibration and found that after running the system for 20 min the control is off by 2 degrees. The system will shut off after reaching 1 degree below its set point and this is normal but the thermostat was reading 72 and my temperature probe was reading 70. Replaced thermostat with and easy to use Blue Easy Reader thermostat.

Performed AC diagnostic on 2010 Goodman condenser. Upon my diagnostic apparently the system it stopped running yesterday while it was on and is no longer cooling the home. 1. Found the red wire In the attic was burnt off due to the outdoor starter on the condenser hat starts the system. 2. Starter showed signs of pitting and burn marks on contact points and was creating a very loud buzzing noise due to weak low voltage coil. 3. System was also fluctuating on the pressures indicating that there’s a contaminate inside the system and it was also slightly low. there was a leak in the past And Is still leaking out at this moment. 4. Amperage for compressor was very high due to wear and tear and will just put the compressor at a higher risk of failing. 5. Outdoor Fan motor was also exceeding recommended Amperage Range Discuss fall condition with Amy and she needs to talk it over with her son regarding what they would like to do but would only want to go through with the minimum repair
