Performed AC maintenance on 2017 unit. Homeowners moved into the home 6 months ago, want to make sure everything is working correctly. They did get a home inspection done by their cousin who is a home inspector and do have a home warranty as well. Cycled system for cooling. Performed attic and duct inspection. Refrigerant levels are in range and system is producing proper temperature split. System is using 407C refrigerant. Checked outdoor unit electrical and system components. Disco box is not fused. Primary motor control is slightly burnt and pitted at bottom contact point. Secondary motor control has gone above its allowed range. Pulled condenser fan motor and thoroughly washed condenser coil inside and out. Filters were recently replaced by customer and they are clean. Went over findings and recommendations with homeowner. Wants to hold off on any work for today as well as wants to hold off on maintenance program. Cycled system, system is operational upon departure.
Performed AC maintenance on 2009 Goodman condenser. Upon my maintenance there were a few points of concern is that were addressed with the homeowners. 5 ton Condenser- 1. Starter showed signs of pitting and burn marks on contact points this is due to wear and tear from high amperage pull overtime from system. 2. System Contained R22 refrigerant which was completely phased out January 1, 2020 at the moment pressures were in range 3. Cleaned off condenser coil 4. Measured condenser fan motor amperage and found that it was on the brink of over amping and is also overheating at the moment. This component rejects heat from the system 5. Measured compressor amperage and found that it was using 16 amps which is fairly high considering the max is 25. This is the reason why the system is so loud 6. Power disconnect was not supplied with any fuses or surge protection, Neither was the indoor unit protected. 7. Filter was heavily Caked in dust and debris, Recommend filter swapped out every 1 to 3
Arrived on site to perform diagnostic on 2004 Lennox system. Homeowner states upstairs unit is not cooling correctly. Would like us to diagnose upstairs unit and possibly take a look at downstairs unit depending on what repairs the upstairs unit needs. Cycled upstairs unit for cooling. Indoor unit kicks on and is blowing warm air. Filters were extremely clogged. Replaced to perform accurate diagnostic. Outdoor unit compressor appears to kick on, but fan motor is not spinning. Checked voltage and electrical components. Found condenser fan motor completely seized up. Fan motor needs to be replaced. Went over with homeowner, approved to replace fan motor and further inspect unit. Replaced fan motor. Cycled system on. Refrigerant pressures are slightly high, which is being caused by an over working compressor. Amp draws on compressor are high, and unit is cooling but is very inefficient. Went over complete findings and recommendations with homeowner. Wants to hold off on any further work,
Arrived on site to perform spring tune up on 1 year old lennox unit. Client stated no issues unit works fine. Condenser in back yard. Furnace and Evaporator coil located in attic. Washed condenser inside and out. Fan motor is good and amps. Primary and secondary motor controls are both good. Conor start up and run amps are good. Pressure are good and cooling at 21 degrees. Inspected indoor unit. Blower assembly good. Moto and inducer motor are both good. Temperature rise is good at 40 degrees. All safety switches are operational. No protection on unit. Recommend adding surge protectors on unit. To protect system from electrical surges and power outages that can damage or even short out systems and components. Cycled system to ensure system operating. Went over all findings and recommendations. Client did hold off but did renew ESA. System is operational upon departure.
Perform system diagnostic on 2002 comfort maker Heater. Upon arrival client stated that fan continuously runs and no cold air comes out. Started off at condenser and found no 24 V was present at contactor. Found no voltage present at thermostat either. Made our way to the attic To investigate the furnace and found that the inducer motor for the heating side of the system and indoor blower motor were turning on simultaneously every single time the system has power present. Isolated all thermostat wires and condenser wires and system does the same exact thing with inducer motor running and indoor fan motor at same exact time even with no call these components. This leads me to believe that the circuitboard is Defective. New circuit board needs to be ordered for A/C to even turn on. Presented client repair options for circuitboard And he does not authorize a board to be ordered. Ultimately will be setting up for a supervisor to return and go over long-term solutions regarding the system.
Arrived on site to perform fall tune up on a 2001 Corsaire system. Furnace and evaporator coil located in upstairs crawls space. Client stated no issues. Cycled thermostat and good and heating. Found black flex ducting used. Filter was dirty and replaced filter at This to,e recommend replacing filter more often as needed due to area surrounding home. Lower assembly and wheel dirty. Creating stress and over working motor. Motor has dried up oil from past with dirt accumulating. Recommend blower cleaning to reduce water and stress on system. Blower motor amp drawls are high but in range as itâ€™s pulling 7.0 amps and max rated at 9.5 . Indicating motor is over working and could fail in future due to conditions and wear being created. Recommend replacing motor to extend life of system. Found secondary motor control to be board line as motor is causing it to get weak and by next visit could be out of range and could fail as itâ€™s gets weaker. Recommend replacing to prevent blower motor n
Complete system replacement with listed equipment
Arrived on site to perform spring tune up on 2000 corsire system. Condenser located in back yard. Furnace and evaporator coil located in attic. client stated no issues from what he knows but did state he just moved in a year ago and what a to see how system is . Did attic inspection. found filter dirty and restricted. Replaced filter and advised he should replace filter more frequently. Checked electrical wiring, connections, circuit board, and components. Blower wheel is dirty and has layer of dirt and dust creating stress and mortar to over work. Motor is ok. Amp drawls on blower motor are above max amps on start up, runn amps is almost at max indicating system is over working. Evaporator coil is dirty and debris. Drain lines are dirty. Blew drain lines out with drain gun. No safety switch advised adding one to prevent attic flooding and creat water damage to ceiling due to the amount of dirt in system. Temperature split is in range 20 degrees. Cycled system in cooling to ensure s
