Completed heat tune up for 120,000 BTU natural gas furnace for Athletic directors side of Restall: Replaced 20x20x1 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 mainofold gas pressure Inspected drain. Combustion, draft and smoke tests: Pass Gas furnace is operating well at this time. Completed heat tune up for Minisplit system, with (2) indoor heads: Filters are clean. Inspected wiring, motors and controls, system has surge protection and power monitoring. Measured temperature rise at each indoor head with both remotes set to high demand heat. Checked refrigerant charge with probe. System operating well at this time.

3/30/26 Barry+Conner Removed failed boiler feed valve and piping and capped off. Cut back 1 1/4” supply to accommodate new Spirovent air eliminator. Installed new Spirovent air eliminator, 1/2” boiler ball valve, backflow preventer with vent piping and pressure reducing feed valve. Also installed (2) 3/4” isolation valves on the supply side which will allow for isolation of boiler components. After fill and testing the boiler safety felief valve began trickling. I discussed with Mike and he agreed to replace. *I did not make this a part of my original estimate for the sake of keeping costs to a minimum but unfortunately it needs to be replaced. Mike agreed. Replaced boiler pressure relief valve. Installed expansion tank at water heater, pressurized to 60psi. Afterwards tested system and hot water. Operating well at this time.

Completed AC tune up for 2.5 Ton Amana AC system 16x20x1 filter ok Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components. Indoor blower motor has surge protector, outdoor equipment does not. Provided email estimate Measured temperature split and static pressure Inspected drains; cleared EZ trap, tested pump; added treatment tabs to drain pan. Checked integrity of compressor motor (mega ohm test) Assessed refrigerant charge checked pressures. AC system operating well at this time. *Steam is still on to campus so cooling not truly available until April 17 when Steam will be shut off.

3/27/26 Performed precision heat tune up on 2025 Laars propane gas boiler. Checked all electrical connections and components. Boiler pressure is at 14 psi. Inspected condensation assembly, trap is clear of debris. Inspected ignition assembly all in good working order. Ran both zones on boiler. Tested circulator pumps. Both zones getting hot. Performed combustion test. 2025 Mitsubishi air handler and wall hung. Aprilaire media filter ok. Wasable filters are clean. Checked all electrical connections and components. Checked temperature rise on both. Poured water in condensation drain and tested. Checked amp draw on all motors. Homeowner had already set up the WiFi for the mini split air handler and connected to her phone. Heat pump is working properly at time of service.

Completed heat tune up for steam coil/air handler system. This is a heat only system. No air conditioning. Inspected wiring and controls, blower capacitor replaced a few months ago 4.5Good Temperature rise 76-128=52° System operating ok at this time.

Completed (2) AC tune ups for tech center 5 Ton R22 system from 2004 22 years old 2nd floor 5 Ton R32 system installed December 2025 1st floor Replaced 16x25x1 filter for basement system. 2nd floor filter (16x25x1) ok For each system: Inspected Indoor and outdoor coils: 2nd floor system indoor coil rust marks as to be expected given age. Inspected wiring, controls, electric motors and components; left estimates for surge protectors for 2nd Floor system. First floor system was installed with surge protectors Measured temperature split and static pressure Inspected drains; cleared EZ traps. Recommend wet switch for Second floor system; device that will shut equipment down if water is detected on floor near equipment Checked integrity of compressor motor (mega ohm test) Assessed refrigerant charge checked pressures. R22 system Good R32 system needed some refrigerant. It was installed in dthe de be so w could not accurately charge it. After charging it today is running at 10° Subco

Resident was not available for us to complete the tune up today. We will have to reschedule to a different day.

Completed all tune ups (3) Ducted air handlers: All filters and belts ok Flushed drains and added all purpose cleaner. Measured temperature splits. Inspected wiring and controls Unit #2 was just charged 50 oz R22 today. (3) Minisplits. All washable filters are clean, Measured temperature splits Checked drains Verified refrigerant charge. Minisplits operating well at this time. Minisplits (#1 and #2) teachers offices are beyond what is considered replacement age.

Charged unit #2 R22 as necessary. 5.oz Tested system operations. Pressures 204/52 15SH 10° SC. Temperature split 65-45=20° Classroom for this system cooled 3.5° during tests. System operating well at this time. They are interested in adding a Minisplit system to the room where this equipment is located. Was formerly a storage area but they are going to converted into. Small classroom. Unfortunately the wrong outdoor fan motor was shipped. I contacted Daikin and confirmed the updated part number and ordered the motor to be shipped to our shop. We will schedule return visit to complete this part of the job,

Condensate solution for Minisplit. Installed new 1” and 3/4” drain piping as well as minisplit tubing; piped to new 115V condensate pump. Ran vinyl tubing into the tunnels. Afterwards tested pump and AC. They will use water sensor tied into the alarm panel/system. No need for 9V water alarm. Removed this from invoice. Recommend adding condensate pan treatment tabs to pump monthly to keep clean. 4 tabs per month. Can buy them from Amazon or supply hous.com just search condensate pan treatment tabs.
