Estimate

Auxiliary drain pan full of water. Ran extension cord and wet vac. Dried. Cleared drain. Brush, C02, vacuumed from termination. Flushed with Gallon H20. Made sure air handler was properly pitched for condensate flow. Used cork pads, a lic of plywood in attic and a random piece of lumber I. Attic to pitch 3/4” drain in such a way as to remove one belly in drain. The drain is very long and starting point is only 6” from attic floor. I made sure condensate is flowing to the termination point after this work. See video. The ultimate solution would be to install an insulated 240V condensate pump inside a pan with its own water safety device. Then use and modify existing 3/4” pvc drain pipe to pumps the condensate to the outside. Left email estimate for this. Checked refrigerant pressures and diagnostics. 130/280 7°SH 2.4° SC. Told her to close windows. System operating well at this time.

The reason outdoor unit was not coming on was a loose low voltage wiring connection at the air handler. (The common wire to contactor coil was loose in wire nut.) To prevent this from happening again I used a WAGO connector for the (4) low voltage common conductors. Completed AC tune up while on site. Replaced 20x20x1 filter. Indoor coil has rust as to be expected considering age. Brushed out trap, Measured temperature split (80-61=19°) Good Inspected wiring, controls, electric motors Checked refrigerant charge R22 TXV metering: 90/199 14 SH, 2.5° Subcooling. Slightly undercharged but not terrible. Williamson is aware of age of equipment and that it is R22. I recommend replacing this system whenever feasible.

Completed Quality assurance for 2.5 Ton AC air handler. Filter size is 16x20x1 Inspected all aspects of install: mechanical, wiring, ductork connections, etc. Put leads of primary side of transformer to the 208V tap based on voltage. Thermostat was left configured as a Cool only thermostat so I configured for heat as a standard efficiency gas forced air. Landed the W wire on the W1 terminal of air handler terminal block so when the thermostat calls for heat the blower comes on. This is not installers fault. Unique wiring situation. I didn’t explain it well to Nick on the day of install. Measured temperature split. 20° Checked refrigerant charge. 5°SC System operating well. Metal passes quality assurance inspection.

Installed new Goodman A/C outdoor and indoor air handler. Reused return and supply . Tapped/ caulked return and supply. Adapted condensate line and installed new ez trap and wet switch below. Adapted high volt and installed new 240v switch. Installed new thermostat and wired in low volt with safeties. Wired in blower surge protector for indoor unit. Flushed line set and connected to new equipment. Installed new A/C outdoor on leveled pad. Reused existing disconnect and ran new whip from disconnect to outdoor unit. Cleaned up work area and tested out equipment. Steam valve for coil was found non functional at the time of install. Unable to test out heat.

Completed AC tune up for Dorm managers apartment: Minisplit with (4) indoor heads Washable filters in good condition. Inspected indoor and outdoor coils: Clean Measured temperature split at each indoor head. Inspected wiring, controls, electric motors. System has surge protection Ensured drain water is making its way to termination point. Verified and assessed refrigerant charge after making demand for cooling from all (4) indoor units, 118 psi suction pressure with 3° superheat: 60° outdoor temperature. Good System operating well at this time.

Completed tune up for Minisplit system server/phone room. Indoor and outdoor coils in good condition. Cleaned washable filters. Cleared drain tube and drain line. Added treatment tabs to pump. Measured temperature split. Inspected wiring, controls, electrical motors. System operating well at this time.

Completed tune up for Minisplit system with 1 indoor head for IT room. Operates in cooling only through the year, Cleaned washable filters. Measured temperature split Drains and pump ok. Checked refrigerant charge. It is ok for now. But I have had to charge this system twice in the past. There is a refrigerant leak. Sent previous estimate to cover refrigerant, then pressure test system to find leaks. System operating well at this time.

There was water in the auxiliary equipment pan. Open wet switch. Removed about of gallon of water from drain pan. Dried as best as possible some areas not accessible with vacuum hose. There was some water on the platforms the dehumidifier is installed on. I used shop vac to clean dehumidifier drain tubing and made demand for dehumidification. There was good amount of debris in this tubing. Also cleaned washable filter of dehumidifier. Dehumidifier was producing water in drain tube after 10 min, Dehumidifier suction line temperature ok, Tested AC. Temperature split 20° 71-51. Added water to evaporator drain no leaks in 3/4” pvc tubing or evap drain pan. Reset wet switch inside pan at a dry spot. There’s an issue with the sump pump. Tim is aware. System operating well at this time.

Tech center second floor system no cooling for a couple weeks. EZ trap float was open. Although there was no water backed up, there was a white paper like debris on top of water, enough to cause trap to open. The drain pan was full of this thin paper-like dirt. This particular drain pan is very shallow and thin so dirt build up this way. Disassembled flue pipe to make evaporator accessible, blew out and then vacuumed this dirt from the drain pan. Added treatment tabs to drain pan. Added 1/2 gallon water to drain to ensure no clogs. Tested system afterwards. Temperature split 21° ok. System AC and Gas furnace is 23 years old. Although it is functioning I recommend replacing to avoid nuisance failure. *I noticed that the 4” vent has a small hole in an elbow where it meets the main stack and there is some soot on top of the drop ceiling. There is also a section of pipe that is touching drywall. I left estimate to pipe this vent in such a way that it meets standards for clearances.
