Homeowner had let propane get very low. Propane company came out an hour before I arrived to fill tanks. At boiler control found error cod 10 “Flame has extinguished 8 times” Bled propane line of air to the inlet of gas valve by opening the inlet pressure tap. Also cleared air inlet screen. Had a few leaves in it. Then reset control and cleared code. Followed manufacturer procedures and found inlet propane pressure to be a tad low so I increased to that it it now 8.5” at inlet during operation. Also followed procedures to ensure proper gas outlet pressure using a combustion analyzer and watching %C02 in flue gas analysis. Combustion tests Pass. Cycled boiler several times to ensure proper ignition every time. Boiler operating well at this time. She agreed to boiler plan membership. Collected for plan and diagnostic.

(2) PECO Tune ups 1st Floor system Carrier 3 ton heat pump with 80,000 BTU propane furnace dates to 2018. Filter Aprilaire 413 ok 2nd Floor system (attic) 2 Ton Air temp heat pump with 80,000 BTU propane furnace dates to 2019. Filter 24x24x1 I’m good condition He had set up his aux heat lockouts wrong. Reconfigured Ecobee aux heat lockout 35°, compressor lockout 30°. 1st floor Fan speeds for heat pump mode which is same as cooling were way too high. Set for 1800-2000 CFM. Considering it is a 3 ton heat pump I set to target 1200-1400 CFM made the dip switch selections on control accordingly. The second floor unit (2 tons) fan speed was also set to high (1700-1500 CFM) only 800 CFM required. Set fan speed to MED Low. Temp rise improved from 12° to 18°. For each system: Filters ok Indoor and outdoor coils in good condition. Inspected wiring, controls, electric motors and components. Provided email estimates for surge protectors. Measured temperature rise and static pressure Inspe

Completed heat tune up for Welder Shop classroom Minisplit. Cleaned washable filters Indoor and outdoor coils in good condition Measured temperature rise. (71-117=46°) Good Inspected wiring, controls and motors. System has power monitoring and surge protection. Checked refrigerant charge using probe. System operating well at this time.

Completed heat tune up for natural gas furnace. Ruud 80% efficiency 120,000 BTU natural gas furnace. Located on second floor of Tech center, Replaced 16x25x1 filter Inspected heat exchanger, burners, flue pipe, inducer assembly and hoses 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 furnace Checked manifold gas pressure Inspected drain. Combustion, draft and smoke tests: Pass Gas furnace is operating well at this time. System dates to 2003. 23 years old. Although it passes safety tests and is operational, parts are no longer under warranty and major repairs are very expensive. Would strongly consider replacing this system.

Arrived o perform maintanance and was unable to do so due to a downed tree and power wires. We will reach back out to get this appointment rescheduled. 2/12/26 Returned to complete maintenance and the building has been condemned and there is no point to do the tune up here.

This is our first time as Dibiase working on this system, LG Multi Minisplit system that has several indoor heads has not been working since Mr. Burbage kitchen manager returned from vacation End of December. Wall mount control shows error code 42 Researched error LG codes. 42 is low pressure issue. Went to unit on roof and put refrigerant probes on ports. Unit short cycles. And cuts off in about 30 seconds. The service probe pressure on suction line is 104 psi standing and drops to 98 psi when unit cuts off. Low pressure switch may be elsewhere in refrigerant circuit. *There was only 1 screw in the access panel for the outdoor unit that serves these units. I put another one in to keep more secure. The temperature is being kept reasonable n the dining are because of other heating sources. I told Steve to have installing contractor service this unit because they have history and intimate knowledge of details (Lineset lengths, charging procedures, control technology, etc)

Completed heat tune up for air handler with steam coil. Replaced 16x20x1 filter. Checked wiring controls, electric motors. System has surge protection System has AC drain and water safeties. Tested system, measured temperature rise (71-143=72°) ok System operating well at this time.

Emergency switch was off (In this case the switch breaks one of the legs of the 208 circuit. High voltage thermostat). Equipment is steam coil air handler. 7.5uF capacitor reading 4.3. Offered to replace, Mike agreed. Replaced today. Afterwards tested system. Operating ok. The unused AC coil is very restricted form the first 30 years being open to dust (coil compartment door was off). But heating ok for now.

Basement zone was 70° when I arrived as was the first floor zone. Insured that thermostats/low voltage wiring was not an issue. Zone panel is operating as designed. This thermostat s opening and closing as designed. The high limit was set to 175° meaning the design water temperature the boiler is set to maintain is 175°. I changed to 185° and then monitored boiler temperature and pressure. As previously quoted system needs pressure relief valve, spirovent air eliminator and expansion tank to operate at peak performance. I cannot purge air without these repairs because pressure relief valve will get stuck open. The other thing I noticed was relative humidity was low around 25%. A bypass humidifier can be installed with an automatic control to get humidity to a point where residents feel sensibly warmer. Boiler dates to 1998. We provided system replacement quotes in November this year. 1 estimate is for Weil McClain boiler and the other high efficiency Laars boiler. Recommend up
