Performed walk through with customer on concerns and reviewed report and building for potential improvements. Created estimate for customer regarding concerns.
A set of normally closed contacts (N.C. 2from SK relay was already. wired to break power to control board.) Originally I wired the other set of N.C. Contacts as well. Tested operations. I also tested secondary drain safety switch and pan safeties as well. System operating well at this time. Ultimately Computer Force and I decided to leave relay wired as I was with 1 set of N.C. Contacts wired to break 24VAC. After testing and confirming that air handler shuts down.
Completed plan member heat tune up for 120,000 BTU natural gas furnace 16x24x1 filter in good condition Inspected burners, heat exchanger, ignitor, inducer assembly, pressure switches and components 20uF blower capacitorln Cleaned flame sensor with 0000 steel wool and verified flame rectification circuit Inspected wiring, controls, electric motors and components; left email estimates for surge protection devices. Confirmed proper manifold gas pressures Measured temperature rise and static pressure Combustion, smoke and draft tests: Pass Discussed and left estimate for AC+Gas Heat plan Membership.

Left estimate for Ecobee thermostat which includes room sensor. Smart thermostat will also allow for control of auxiliary heat lockout. Heat pump is operating well at this time. Homeowner decided to become AC/Heat pump plan member, to install EZ trap and (2) Intermatic surge protectors today. Collected half of balance today. Our office
Installation of customer supplied Smoke Detectors and Relays for both Furnace systems of the Tech Center. Complete wiring of the smoke detectors and relays on each system. Test operation of systems upon completion. 3/8/24: For basement HVAC system: Wired smoke detector normally closed contacts to break low voltage power thereby shutting down system is in duct smoke detector detects smoke. Tested by removing one of the normally closed contact wires: Good
Completed heat tune up. Equipment is heat only/ steam coil. Located above drop ceiling in bathroom,. Replaced 14x14x1 filter. Filter was very dirty recommend replacing every 2 months during the heating season. Inspected wiring and components. Found weak 5uF blower capacitor. Left estimate to replace. To shut air handler off use breaker, panel is in the same room. Temperature split (70-152) System operating well at this time.
Completed plan member heat tune up for 60,000 BTU natural gas furnace Replaced 16x16x1 filter Inspected burners, heat exchanger, ignitor, inducer assembly, pressure switches and components Cleaned burners with wire wheel. Cleaned flame sensor with 0000 steel wool and verified flame rectification circuit Inspected wiring, controls, electric motors and components; left email estimates for surge protection device Confirmed proper manifold gas pressures Confirmed inducer vacuum in low and high fire operation Measured temperature rise (68°-110°= 42°F) and static pressure Inspected all components of drain Combustion, smoke and draft tests: Pass Discussed and left estimate for AC+Gas Heat plan Membership. Furnace is operating well at the time of this tune up.
Installed ECM surge protector. Tested system operations. System is operating well at this time.
Completed heat tune up for 70,000 BTU natural gas furnace 80%Eff. 16x16x1 filter ok Cleaned flame sensor with 0000 steel wool Inspected flues, burners and heat exchanger Measured temperature rise (72-140) Checked gas pressure Inspected wiring, controls, electric motors and components Carbide ignitor is worn and reading just outside of manufacture rating (resistance value of ignitor measured when ignitor at room temperature) Left estimate to replace ignitor with OEM ignitor. Combustion and draft tests: Pass Equipment (including AC) is 24 years old. Williamson should anticipate breakdowns and issues. Would consider upgrading system.
Attic air handler control board had failed. No LEDS. Made sure transformer is providing 24V to board, that fuse in good and that there are no open switches. Several spots of obvious corrosion on control board. System is down and has been down. Undercharged on refrigerant as diagnosed last year. Please consider system replacement quotes provided by DiBiase. Shut air handler breaker OFF Completed tune up for basement (1st floor system) Mr. Fisher replaced failed ignitor and gas valve over this winter. Completed maintenance for 80,000 BTU furnace in basement: Replaced 16x25x1 filter. Was very dirty. Recommend replacing ever 2 months. Dirty filter could very likely e the cause of the failed ignitor Used soap bubbles on all gas piping joins after gas shut off valve to ensure there are no leaks. Gas pressure if new valve needed slight adjustment. Cleaned flame sensor with 0000 steel wool; verified flame rectification circuit. Measured ignitor ohms (71 ohms) Good.271N Combustible and dr
Completed cooling tune up for 3.5 Ton AC system: Replaced 20x20x1 filter; filter was very dirty. Recommend replacing every 2-3 months. Dirty filters cause a number of mechanical problems. Inspected wiring and controls. Megaohm test on compressor motor winding reading caution. Indication that winding on compressor motors are not in great condition/beginning to fail. Dirty filters cause this issue. Inspected condition of both the indoor and the outdoor coil Checked condensate drain and trap. Monitored R410A refrigerant pressures and diagnostics using charging jacket. Pressures 110/300 15 SH 12 SC outdoor temperature 51°F; Good Refrigerant Charge was added in July of 2022. We checked for leaks using UV light. No indication of leaks at indoor coil. The inside of the cap for the port at indoor coil had some dye. We made sure this schrader core was tight and verified that it was not leaking using leak detection bubbles System operating well at this time,
Completed heat tune up for boiler 100,000 BTUs Inspected flues and heat exchanger ger Checked hydronic piping and components Measured return and supply piping temperatures Monitored boiler temperature and pressure Co,bastion and draft tests PASS. Strapped flue piping to try to help with vibration. System is old. Lots of rust in burner compartment and on surfaces of boiler. Boiler operating well at this time.
