Luis 1-9-26 customer called in for noise heat from oil boiler, customer recently had some baseboard repair and now no water flow. Found supply pipe valve closed off, open up valve and water started to flow. Piping is getting hot boiler is in very poor condition, I did inform customer we will not be able to work on boiler is there is an issue with burner. Would recommend getting an estimate to replace boiler, we do have finance available office to follow up with customer. No other work was performed during today’s visit other than opening water valve in the supply piping. Customer uses ventless propane fire place, would recommend not running fireplace at all times for safety purposes. Customer should read homeowners manual and follow their instructions on how to use it.

Full assessed water leaking situation. Found feed tube was not in the correct spot on the tray. Found feed tube had popped out of place. Found water leaked from humidifier and went underneath hard wood flooring. Shut off water for now to humidifier. Let our office know the details, our office to contact customer on next steps. Dried up water as much as possible.

On arrival, customer was saying system struggle to get up the temperature. Found air filter for 413 was very dirty, this is a customer supplied filter. I did confirm that tan and Liz did change the air filter. I recommended to the customer to change the filter more often and use a 410 filter . I tested all 3 phases of the unit fan , electric heat ,and heat pump. I Checked my temperature splits, and checked the outdoor heat pump is in good working order. Customer just had a clogged air filter that was not allowing the system to produce good airflow. I did talk to the customers and they told me that they set their thermostat at 60°at night and then they turn it on in the morning at 70° so it will initiate electric heat sooner to try to get up to 70° . I to.d them to keep at least to a 5° separation. I checked the thermostat settings and they were good. Per the customer he wanted me to set the droop to 4° not 2°. I collected for 84.15 paid by cc. Everything is back up and running at t

Installed new aprilaire 620m bypass Humidifier. Cut out hole in return and mounted Humidifier. Installed takeoff in Supply and ran hard pipe to Humidifier. Wired Humidifier into existing eim using u1 terminals. Ran Humidifier drain to existing condensate pump. Reprogrammed thermostat and tested operation.

Homeowner had let his oil get close to empty and had tank filled. He knows how to bleed his oil burner pump and did so after oil tank was filled. He also replaced oil filter. What I discovered was clogged .60 80A nozzle. Offers to replace and align electrodes. He agreed. Replaced nozzle, bled pump and system completed ignition as designed. Did have to burn off some oil in chamber from previous missfires. Monitored cad cell ohms using contractor tool 120 ohms. Combustion smoke and draft tests: Pass Temperature rise Good. Cycled furnace 3 times no issues. Left estimate for Oil Heat plan Left estimate for oil heat and AC plan.

Looked over lock out settings in the thermostat. Heat pump was originally set to 25 degrees ( electricity rates were better at the time). Now changed lock out temp to 40 degrees and set auxiliary lockout at 50 degrees. Propane is currently cheaper that electricity to run. Tested operation. Hybrid system is working properly at time of service.

2.5 yr old high efficiency gas furnace off on pressure switch error. Found pressure switch kit stuck closed. Cleared tubing and freed up pressure switches. Tested system operation and cycled several times. System now operating properly but issue could recur. Recommend replacing pressure switch kit to avoid future issues. Ordered part for return visit. (Part warranty only) 1/6/26 Replaced dual pressure switch. Tested system. Verified draft at both pressure switch ports. Combustion and draft tests: Pass. Measured temperature rise. System operating well at this time, *This repair includes 2 year part and warranty. Collected balance.

Fully assessed humidifier operation. Found humidifier working properly and had water in the tray. Talked to customer about upgrading to Aprilaire 600 humidifier and still using automatic control on system. Provided estimate. Customer was concerned because the change water panel light was flashing and humidifier was recently serviced. Explained to him that this is just a timer in the control and if it was not going off while we were on site it doesn’t always get reset. Found automatic control reading 30% humidity. Also found that after looking into we used customer supplied pad during that service and homeowner was not charged to fully service humidifier. Used psycrometer and found humidity was between 30% and 31% not terrible. Humidifier is working at time of service.

Installed new control board and found that the con code was still coming up for communication error. Found after investigation that when the install was completed the Exsisting wire between the outside heat pump and control board was only a 3 wire that went above drywall. No c wire was used which is what is causing the communication error. Had to run new 18/5 wire above drywall ceiling to outside unit. Was able to get it. Installed now no con error is present. System is working properly at time of service.

Performed precision oil tune up on 15 year old Weil McLain oil boiler. Checked all electrical connections and components. Replaced Rf1 oil filter, pump strainer, and 1.25 80b nozzle. Vacuumed soot from heat exchanger and smoke pipe and cleaned chimney base. Used furnace cement to seal around chimney. Found mixing valve is not working correctly on boiler this is causing the inconsistency in hot water. Checked over aquastat settings. Performed combustion test. Oil boiler is working properly at time of service.

Installed new electric heat contactor. Tested system and verified amp draw of 20KW electric heat kit. Balance is already paid in full. System operating well at this time.

Found burnt and seaparated wire on one of the contactors of the 20KW electric heat kit. (The bottom one that is fed by right side air handler breaker) I stripped wire and installed newly stripped wire (both leads into contactor) I also replaced the lug on the terminal of the burnt wire. Made sure to properly torque wire. Also determined that the leads from contactor to the heat kit itself were a little lose so I made new female spade connections there. I did not have a double pole contactor on truck to replace but this will do until we can come back to replace the double pole contactor. Afterwards tested system and measure amp draw of each breaker. 40A on each circuit. 80A total. Good She would prefer if we came back to do the contactor next week. She is going to Florida for winter. There is a 5 year parts warranty that expires 7/22/26

Issue Is it had stopped heating and the blower motor only was running. I had called her a few hours before my arrival and told her to reset breakers. When I arrived thermostat setpoint was satisfied 68° Found dirty 16x20x1 filter. Replaced today. I explained that with a dirty filter the airflow restriction more than likely caused a limit switch built into the strip heater to open and shut unit off and run the blower motor. I also noticed that a 17x20x1 filter would fit more snuggly in rack and thereby protect the indoor coil from getting dirty a little better. I showed Andrea how to order these filters online. Completed heat tune up for Electric heat air handler. Measured amp draw of 15KW heater 60A Good Measured temperature rise Inspected electric motors and components. Equipment has surge protection. System operating well at this time.

picked up old WH and brought back to the shop
