Reviewed equipment with customer. Amir stated his enegy gas bill increased by 50 percent this year over last year. House temp was at 73 degf. He mentioned it was the same lasy year. Peco saying it is 6 degf colder this year over last year. Need to review bill data and also review the temperatures to validate data. Reviewed settings on thermostat and furnace, checked air filter, and performed combustion test. Increased high stage setting to 300 seconds from 600 seconds. This will speed high stage operation and will cause unit to shutbdown sooner. Informed Amir this may be best for efficiency but it is not best for comfort. Amir will email.me bill data for further anaysis. Discussed also how a humidifier can help with overall comfort and help lower thermostat settings to save on gas.

I checked the air filter and replaced, filter size is 20x22x1 . Also serviced and tested the customers humidifier . I set the humidistat at 35%. I Inspected the indoor coil and tested electric heat package. Took temp splits for the electric heat and blower motor amperage draws. I looked at the outdoor heat pump and tested for an outdoor btu output. Inspected the outdoor components and unit pressures. Everything is working fine at this time of service. I sent a payment link for the humidifier service for $59.00

Returned to the customers home to replace there gas valve on the unit on the left side of the house. I turned the power off and the gas. I removed the failed valve and replaced with new. I tested for gas leaks and then turned the system back on and dialed in the 1st and 2nd stage gas pressures. Evers back up and running at this time of service. Cole Ted for labor warranty for $462.19 paid by cc.

arrived to the customers home to service their 14 yr old oil furnace system. I started with checking the air filter and replaced, supplied by the customer. I checked all my electrical connections and voltages. I checked and replaced my strainer and nozzle , and the oil filter. I inspected and set my electrodes for proper gapping for optimal performance. I inspected the flue pipe for corrosion and pitting. Inspected my heat exchanger and the chimney for clearance. I bled the oil burner and tested system for smoke and combustion. I took temp rise splits at the return and the supply. Everything is running fine at this time of service. Arrived to the customers home for 2 heat pump check ups . I checked all electrical connections and voltages . I checked the air filter and found both are good. I Inspected the indoor coil and tested electric heat packages on both systems. Took temp splits for the electric heat and amperage draws. I looked at the outdoor heat pumps and tested for an o

Found failed Temperature+Pressure Valve on 50 gallon propane water heater. Fairly serious leaking on valve a good amount of water had leaked including outside pan. I drained water heater as necessary to stop trickling of valve. Expansion tank and temperature and pressure relief valve have failed. Provided email estimate to replace. Also provided mail estimate for these 2 PLUS whole home pressure reducing valve. Also provided estimate for new water heater. 1 with 6 year tank warranty. The other with 10 year warranty. Gas valve and gas control are OFF. Water heater is drained and valves off so as to stop leaking T+P valve.

Found oil furnace primary on soft lock out. Used contractor tool to troubleshoot: past 2 cycles “Did not light” Inspected nozzle assembly, cad cell eye and the past cycles as well. Cad cell ohms good. Attached bleed through wrench to bleed port of pump and bled oil line which had a considerable amount of water until I had a full column of oil present in bleed hose. Closed bleed port. Light off was a little hard this time around because of oil in chamber. Also used Beckett contractor to extend pre purge run time from 15 seconds to 30 seconds and also set the post purge time to 30 seconds. Was set up for 0 post purge time when I arrived. Light off is now much smoother as a result. Oil tank is old not in great condition. Oil line is buried. Recommend replacing tank. If a grandy 275 is to be used and tank in same place That wall will have to be deconstructed/demoed. Left estimate for plan memberships Oil Heat only Oil Heat+AC Oil furnace operating well at this time.

Fully assessed no heating situation. Found system locked out when we arrived. Found geothermal was locked out on a code 4.
