Customer will be in contact wether or not she will complete the work. Upon arrival found the elements not burning or firing up. Found no humming coming from unit. Which is a clear sign of them not working if power is ran to them. Would suggest replacing the elements and go from there.
Paid 60 will talk with wife about the inspection. Upon arrival found the kitchen sink line clogged would suggest a camering due to the house being on a slab and there could be a dreakage after 35 ft.

I spoke with installation manager and sales person regarding the fact that the oil furnaces transformer was not producing control voltage. I was told to replace the transformer to get the unit operational. I then operated the unit on cooling mode and checked the refrigerant pressures and added 10-12oz of r410a to achieve 4-8 degrees superheat and 20+ degree delta temperatures across the evaporator coil. Unit operating normal.
I was talking to the customer she told me her unit is fixed she doesnâ€™t want the service
Service call on 07/22/19 On arrival set unit to call for cooling the unit is tripped wet switch reset it checked electrical connections checked voltage and amps measured supply and return air temp checked air filter checked condenser drain line is clogged I gave quote for customer cleaned the drain line with nitrogen and vacuum the drain line she accepted the quote cleaned the drain vacuum it tested water is running out normal checked electrical connections checked voltage and amps measured supply and return air temp unit operating normal at this time collected $89 dispatch fee and $283 for cleaning the drain line with nitrogen total $372
I recovered the refrigerant, removed the sticking txv and refrigerant filter drier. I brazed in the new txv and filter drier. I pressurized with dry nitrogen to 250psi and let hold pressure and then flushed the lineset from high side to low side. I pulled the system into a <500 micron vacuum and charged the system until I had 10 degrees subcooling, normal refrigerant pressures and 23-24 degree delta temperatures across the evaporator coil. Unit operating normal. Customer paid remaining balance.
Snake main line. Main line clogged will also snake from kitchen to fully clean lines.
Upon my arrival the unit was running in cooling mode. I had 75 return and 60 supply, which is only 15 td. I went to the outdoor unit and applied my refrigerant gauges and had low suction and low discharge pressure with both high superheat and subcooling. I isolated the sensing bulb and in the process of doing that noticed a large puddle of water in the bottom of the duct under the coil. Heating and cooling the bulb resulted in little to no change of suction pressure and as the unit runs the subcooling gets higher and higher. The unit need to have the txv valve replaced. Customer approved this repair and paid $600. I completed a parts order form for the parts needed. I told the customer the office will call to schedule return visit to fix the system. The unit is operating some so customer does have some cooling in the meantime.
On arrival found system not working correctly,found system had leaked out all the refrigerant.i then presssurized system with nitrogen ,I couldn't find any leak .pressure held at 350 ,also vacuumed system and held at 500 microns .i recharged system with 67oz of 410 ,tested it ,unit operating normal

Hot water heater flue pipe was not secured properly and fell off the tank. I mounted it securely and sealed up any cracks or screw holes with aluminum flue tape. I took before and after pictures for warranty reasons.
