Installed control board under warranty. Configured new control; Set fan speeds in heat and cooling. Afterwards powered on system and tested. Left thermostat set to “Heat 72” System operating well at this time.

Expansion tank and pressure relief valve. 12/12/25 Isolated boiler using available valves. Drained boiler as necessary. Removed failed pressure relief valve and installed new with proper piping. Removed failed expansion tank. Tank was seized in the 1/2” tee so I had to cut out additional fill piping and repipe with a couple new fittings. Installed new hydronic expansion tank pressurized to match boiler pressure 18 psi. Includes isolation valve Filled and purged isolated boiler. Afterwards tested all zones and the functionality of the spirovent air eliminator. Good Told Mr. Chillman that yes the dining room thermostat is a heat zone thermostat as well as the AC/air handler thermostat. Select mode: Heat and then set setpoint temperature to heat that zone. Second floor thermostat not working. Provided email estimate for appropriate thermostat. She said they rarely use that thermostat but estimate is there if they need it. Opening the baseboard louvers will he.p greatly with heatin

Completed heat tune up for natural gas furnace. Replaced 16x25x1 filter Inspected heat exchanger, burners, flue pipe, inducer assembly and hoses Inspected hot surface ignitor and verified resistance with meter Cleaned flame sensor and verified flame rectification circuit Measured temperature rise and static pressure Checked wiring, controls, electric motors and components Checked manifold gas pressures Inspected drain and pump. Completed humidifier service: replaced Aprilaire 35 water panel, cleaned housing and tested operations. Combustion, draft and smoke tests: Pass Gas furnace is operating well at this time.

Completed (2) Heat tune ups Replaced BOTH 16x25x1 filters. Attic filter heavily caked in flooring dust. Turn system off when doing flooring and replace filters often when doing construction. Upstairs system is heat pump with 7”5kW capacity electric heat. Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; 34A 7.5 kW at 197V: Good Measured temperature split and static pressure Inspected drains; Checked integrity of compressor motor (mega ohm test) Tested defrost. Assessed refrigerant charge checked pressures. 278/77 Outdoor temperature 17°F Good Heat pump system operating well at this time. First and second floor system is 80,000 BTU natural gas furnace: Inspected heat exchanger, burners, flue pipe, inducer assembly and hoses Inspected hot surface ignitor and verified resistance with meter Cleaned flame sensor and verified flame rectification circuit Measured temperature rise and static pressure Checked wiring, controls, ele

Performed quality assurance on Mitsubishi electric air handler and basement indoor unit. Tested system and heating mode. Checked all electoral connections and components. Check temperature rise. Checked all penetrations. Homeowner was able to download app and was able to connect straight to basement indoor head with Wi-Fi. Upstairs air handler would need Kumo 2 interface. Homeowner mentioned about getting it themselves and connecting. System is working well at this time. Collected final balance.

Performed quality assurance check on laars boiler. Checked all electrical connections and components. Tested both zones. Checked settings in boiler. Performed combustion test. Moved 3/8” vinyl tubing per homeowner request to zip tie to pvc instead of hot boiler pipe to prevent melting. Boiler is working properly at time of service.

Completed heat tune up for natural gas furnace. Replaced 16x16x1 filter Inspected heat exchanger, burners, flue pipe, inducer assembly and hoses Inspected hot surface ignitor and verified resistance with meter Cleaned flame sensor and verified flame rectification circuit Measured temperature rise and static pressure Checked wiring, controls, electric motors and components; there are no surge protectors; left estimate for a surge protector for each of the 2 main circuits of system Checked manifold gas pressure Inspected drain and pump. Also left estimate for surge protection package. Surge protection for both circuits of the system $31 discount as opposed to doing them both separately. Combustion, draft and smoke tests: Pass Gas furnace is operating well at this time.

Completed heat tune up for Trane Minisplit system with (4) indoor heads. Cleaned all washable filters. Measured temperature rise at each indoor head. Each ranging from 20° to 25°temperature rise when all (4) heads running at high demand heating. Checked wiring, controls, electric motors. Checked refrigerant pressures and found to be good. This system has random compressor and outdoor fan malfunctions in cooling without producing and error codes and I looked through system in cooling last year. As a reminder, We provided estimate to replace system. System operating well in heating at this time.

Completed heat tune up for natural gas boiler. Inspected flues and chimney: heat exchanger flue passage clean. Cleaned burners and burner compartment Inspected pilot assembly. Inspected hyrdronic components: air scoop, feed valves, expansion tank, circulator. Repairs were made last year: air elimination (spirovent repair kit), feed valve, purge tee, expansion tank, temperature and pressure gauge and relief valve. Checked wiring controls and components. A surge protector can be installed at 120V feed (relay board) would protect controls. Presented estimate. Homeowner agreed. Completed work today. Installed AG3000 surge protector for boiler. Breakers are mislabeled in panel. I was able to use stairs switch to shut off circuit and install surge protector Tested both zone valves and measured temperatures: Both zones operating well. Combustion and draft tests: Pass System operating well at this time. Collected for plan renewals and surge protector today.

Completed heat tune up for natural gas furnace. Replaced 16x25x1 filter; recommend replacing filter every 2 months. Inspected heat exchanger, burners, flue pipe, inducer assembly and hoses; some surface rust on heat exchanger cells but no cracks. Inspected hot surface ignitor and verified resistance with meter Cleaned flame sensor and verified flame rectification circuit Measured temperature rise and static pressure Checked wiring, controls, electric motors and components; Checked manifold gas pressure Inspected drain and pump. Cleared trap as best as possible (it has no clean out) Left estimate to replace trap with EZ trap with cleanout and overfill protection switch, Combustion, draft and smoke tests: Pass Gas furnace is operating safely at this time. System is well beyond replacement age. The air conditioner is an R22 system with slight refrigerant leak. Recommend upgrading system to avoid any expensive nuisance no heat or no cooling incidents.
