Since their issue started they called a family member who talked them through cleaning the flame sensor. Since then furnace has been operating well. Verified flame rectification circuit. 3.3uA DC Good Combustion test Pass Technically the gas line section that is inside the furnace needs to be hard piped. Provided mail estimate to re pipe section of gas line in furnace compartment. Humidifier needed maintenance. Homeowner agreed: replaced #10 panel, cleaned housing, set water flow from feed valve, set humidistat to 35%, opened bypass damper. Completed heat tune up for natural gas furnace. 20x20x1 filter ok 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

2 plates were missing from air curtain and unit was never properly tested at startup or on recall. Ordered plates directly from Mars mfg, no charge. Installed 2 plates, one on each end of air curtain. Reset limits and tested operation. Unit is functioning as designed.

Found boiler drain valve leaking. Also found the 1 1/4”x 1” bushing that is piped into the temperature and pressure tee (1 1/4” x 1 1/4” x 1/4”) was leaking. I repaired today, replaced bushing with bell reducer. However after spending time with boiler the top side of the tee was still leaking. We will need to replace the temperature and pressure gauge tee itself. Very very slow leak at the tee itself. New boiler drain valve is not leaking. After running system found a 1” sweat coupler leaking. This was not part of our install. Ryan asked that I provide estimate to replace as many of the older sweat valves that I thought were problematic or could become problematic as possible. Provided email estimate to replace problem fittings only. Provided email estimate for problem fittings plus additional fittings on supply piping. Please give technicians time because they will have to purge system after repairs are made. Boiler operating well at this time. There is a bucket under the slow

12/11/2025: Noel said the heater was not putting out any heat and airflow was weak. Removed covers and inspected components. Found both temperature limits tripped out. Airflow from unit was very weak. Checked blower rotation and found to be rotating in incorrect direction. Switched L2 and L3 leads and tested rotation. Reset limits and tested operation. There are 2 sections of unit that air is bypassed around heating elements. Need to contact manufacturer about this issue as one limit tripped again during testing. Relocated door magnet so unit will work off of thermostat only as this is how Noel would like to unit to operate. Hung new mars air curtain above main door. Ran new power wire through conduit down to lower level through drop ceiling to breaker panel. Installed new triple 50 breaker in panel. Made all high andnlow voltage connections to unit.

Removed original burner manifold. Vacuumed rust from burner compartment with manifold removed. Installed new burner manifold. Replaced female spade connector for flame sensor. Afterward tested system operations: temperature rise and combustion analysis: Good Also forced open a manual damper to the back bedroom. Wants an estimate Minisplit for the garage and possibly add (2) other heads one being to the 1st floor back bedroom and the 2nd floor master bedroom. Zoning would involve (1) 8x20 bottom mount trunk damper, (1) 8x18 side mount trunk damper. Wireless or 2-wire thermostat for second floor and all new controls. See previous job for photos of dampers. I reminded them that I recommended upgrading HVAC system. 19.5 years old. Parts are very expensive at this point and will be difficult to source. Furnace operating well at this time. Office follow when you can to set up consultation.

Installed new well McLain boiler. Adapted flue pipe and installed new automatic draft damper and draft hood. Adapted high voltage and installed new switch. Adapted boiler supply piping and installed new spiral vent, expansion tank, water feeder, shut off valves, air bleeders. Adapted boiler return and installed new circulated pump and shut off valves. Adapted low voltage and reused existing thermostat. Cleaned up work area and tested out equipment. Ran new thermostat Wire for airhandler in attic to existing boiler thermostat in kitchen. Rewired and programmed kitchen thermostat for fuel fuel operation. Will have to return to patch small piece of drywall that was needed to cut to run the wire

Equipment is Oil boiler that was converted to natural gas about 8 years ago. 5 Zone relay panel. 5 circulators. 1 is for indirect tank. Inspected and cleaned flue piping and heat exchanger. Lots of debris. Also opened burner door from hinge and vacuumed combustion chamber. Inspected hydronic components: expansion tank, relief valve, water feeder+backflow preventer assembly. Monitored boiler temperature and pressure. Paid close attention to second floor zones/master bedroom as it has become air bound in the past. Zone is not air bound at this time. Temperature delta good. Checked operation of Carlin gas burner Combustion, smoke and draft tests: Pass System operating well at this time.

Installed new magnetic door switch and tested operation. Also performed a on air curtain checked electrical connections and components. Tested operation air curtain is working properly at time of service.

Talked to customer about loud noise. Homeowner showed me that he was getting a small rattle from the supply vents. Looked over airflow settings at air handler. Found cfms were set to 363 cfms per ton. Explained to homeowner that we don’t want to really adjust any lower. Checked 454b refrigerant pressures they were good at 351/128. Asked homeowner about doing the heat tune up, he would like to keep his appointment in December. Heat pump is working properly at time of service.
