Performed cooling maintenance on a Bryant AC system Blower speed on high 0.7"wc total external static = 1090CFM actual airflow delivery 0.3" drop across the filter when brand new 0.13" drop across evaporator coil Blower is in OK condition Drain is clear 17⁰ delta T across evaporator coil 10⁰ subcool Capacitor tested 39.9/4.6 Removed top of outdoor unit and washed Condenser coil from the inside-out. System is operating within factory specs at this time.

Upon arrival the northeast corner system located in the old original basement was turned off. Pastor Jim's description of the noises could not be heard or duplicated during today's two-hour visit however water was discovered on top of, throughout, and in the return air box indicating a air conditioning problem. The 20x25x1 air filter is very dirty but not matted however a combination of a dirty air filter, a frozen over evaporator coil, water on the motor, and undercharge refrigerant could all contribute to erratic blower motor operation After multiple attempts to recreate any furnace noises heard while the air conditioning was not running, a air conditioning running test was performed to identify the source of the water throughout the furnace. Initial run testing discovered the refrigerant pressure is very low running at 55 PSI with 92 outdoor temperatures and 79 indoor temperature. Recharge 31 oz of r422b to achieve 70 & 228 with 16 superheat and 5 subcooling After a short amount

No answer at door

Homeowner wants quotes for both full system replacements and new Aprilaire 600m humidifiers on each system. Ac system originally suspected low on refrigerant but is not responding to pressures properly there seems to be a blockage in the indoor coil not allowing unit to cool properly.

Cooling preventative maintenance performed Check filter - 16x25x4 new today Check coil for any buildup debris in drain pan and flush with water Set up thermometers Rinse down outdoor coil with garden hose Check capacitor MFD - 45+5 @ 44.01+5.02 Check OD fan Amp - 0.63 Check compressor Amp - 7.84 Verify pressures and HP-SC/LP-SH 324/8°\118/12° Delta T - 19° The Air handler and AC are in optimal running conditions.

Upon arrival found unit running with -11psi need to build quote tomorrow

25 year old Trane AC Replaced condenser fan motor, blade, and capacitor

Upon arrival inspected ac unit found unit wouldn’t come on outside. Inspect electrical panel and found bad capacitor swollen. Replaced capacitor and test ran unit. Unit cooling with 11° subcool and 344 psi head. Coil clean. No other concerns at this time.

Outdoor unit capacitor swollen and shorted to open circuits. Install replacement 440 volt power supply, 45 + 5 Reestablish high voltage power and run test in cooling mode.

Perform deep cleaning on Outdoor coil due to severe buildup and high head pressures. Pulled cage and hoses unit from inside out. Unit running with 18° delta T after cleaning

Replacement warranty: Found liquid line filter-drier had a 35⁰ temperature drop across it. Pumped system down Cut out old drier Brazed in a new drier Pressure tested Evacuated with vacuum pump down below 250 microns Performed multiple decay tests to be certain system is dry and tight Gave it a final pull down to 220 microns and released the charge from the outdoor unit Performed charge mode test for a very long time to be sure system is charged correctly AND operating at rated capacity Double checked system settings in the installation menu System is working beautifully now **Washed outdoor unit. It already had a thick coat of cotton wood or similar pollen on the coil** Strongly recommend our maintenance plan to keep the system running at peak efficiency and capacity

Replace faulty blower motor with new oem motor covered under parts warranty but no labor warranty. Test run operation in fan only and cooling mode. Blower motor bogging was not present with the new motor. Amp draw is within spec and filter is clean. System is operating in cooling at this time.

Upon arrival discovered bad run capacitor. Replaced and test ran system. Unit started cooling no issue, outdoor coil clogged with cotton wood, hose down coil and check pressures/ delta T 25° delta T and 7° subcool unit running good at this time

Bryant evolution furnace has a failed blower motor Outdoor coil is beyond repair from attempted cleaning with a power washer. Due to cost of repairs and age and condition of the equipment, furnace and AC replacement are strongly recommended.

No cooling call for an ICP AC Capacitor failed, Compressor won't start Condenser coil plugged with pollen and debris Signed up for gold maintenance Performed maintenance cleaning Replaced 45/5 capacitor System running 0⁰ subcool Topped off refrigerant to get 8⁰ subcool Went with low end of subcooling spec due to extreme load on the system

Daikin system throwing a communication fault on the thermostat Daikin interface module showing a 3 flash, thermostat comm error Checked wiring Doubled up conductors for comm wires Reset system Error still present Tried a new thermostat Error still present Tried a new interface board, no change in Error Disconnected all comm wires, connected only the stat Communication good Tied everything back in one at a time. Also doubled comm conductors for outdoor unit and twisted together remaining wires to common to make a shield System operating normally at this time. Did not end up using new thermostat or interface board.

Performed cooling maintenance on a York AC Filter is new Blower is clean Drain is clear Refrigerant charge is where I left it 2 years ago at 10⁰ subcool Capacitor in spec Tore down and washed Condenser coil System is within operating specs at this time

Performed cooling maintenance Filter is good Drain is clear Blower is clean Noted signs of water leak at some point from the furnace trap It is currently dry... we may need to replace the trap gasket during the fall maintenance Tore down and washed outdoor unit Refrigerant charge is correct: 8⁰ subcool Capacitor in spec Wiring undamaged and secure System is operating within factory specifications at this time.

Performed cooling maintenance on a Trane AC system Filter is new Blower is clean Drain is clear Humidifier is shut down for summer Put air probes in return and supply ducts Checked outdoor unit Refrigerant charge is correct at 8⁰ liquid line subcooling 16⁰ temperature split across evaporator coil Capacitor tested in spec Wiring is secure, no signs of insulation damage to conductors Washed Condenser coil System is operating within factory specifications at this time

Maintenance recall On maintenance visit, found filter was wet. Customer had just replaced the water heater moments before our arrival. He explained when draining the tank, water was spraying all over the wall and air handler. We thought that was thr source of the wet filter Drain pan on the coil had no standing water in it. Drain treatment tablets were put in the coil drain pan as part of the maintenance. Upon arrival today, the tablets from Monday were dissolved and gone. Poured water into the pan. Drain was clogged. Cleared the drain clog. Put more tablets in the pan Poured nearly a gallon of water into the coil drain pan. It all flowed perfectly without any overflow.

2018 Trane XR 16 seer 2.5 ton cooling system is running an excellent condition and ready for summer Air filter is on schedule with homeowner and inspected today, run test cooling equipment on the indoor unit, inspect evaporator coil and flush cooling drain system. Humidifier already shut down for the season. Inspect batteries on the Honeywell T series thermostat Water flush condenser coil and run test cooling equipment for refrigerant pressure verification. Inspect electronics, power supplies, and starting relay. All equipment is perfectly within specs and ready for summer 53° Fahrenheit supply temperature with 120 suction and 220 discharge with 8°f subcooling No other recommendations at this time

Upon arrival, turn system on into cooling. Furnace blower is operating properly. Installed new airfilter to ensure proper testing environment. Inspection of outdoor unit shows that refrigerant levels are low. System is operating with a 22-24F super heat. Target range is 10-16F. Charge system up to proper refrigerant levels and inject leak stop+dye. Leak stop is not guaranteed to fix the leak, nor is the UV dye guaranteed to help find a leak. Charged up to proper refrigerant levels with 15oz of 422b refrigerant. Test ran system with measurequick. Piston metering device. System is operating with an approximate superheat of 10-12F. Delta t indoors is 22F. System is operating within refrigerant specifications at this time. No other issues suspected at this time. Due to the age of the unit, preparing for replacement is highly recommended.
