Nickel and dime for service charge. Fee for estimates.
Both unitâ€™s have propane furnace backup heat sources. The furnace in the basement #2, had low manifold gas pressure causing a slight blow back from failed ignition attempts and gas building up in the chamber. I inspected the heat exchanger for breaches but could not identify any and by increasing the manifold pressure to 11.5 it began igniting without the failed attempts. The furnace in the attic cycles completely normal. I setup the hydronic system to operate in heating mode and turned all the radiant floor heat valves to open and tested the radiant heat. The unit for the upstairs was extracting heat from the water and had normal temperature rise. While checking the electrical wiring and electrical systems I found all were within specification except that the voltage distribution systems for each unit was badly pitted and the one for #2 was very burnt. Ultimately both were replaced. At this point the equipment is setup for heating season and both units are operating normal.
Water heater power vent 50 gl tie onto existing connections. Install customer supplied faucet. Was unable to mobily deposit.
Connected existing dryer vent. Customer had most materials, we just needed to add duct tape and extra straps to secure hose. Tested dryer. Customer satisfied. Also asked us to replace 2 filters for them.
VOLTAGE ABSORPTION SYSTEM REPAIR Service call on 10/07/19 On arrival set unit to call for cooling unit is comes on but the compressor is not checked electrical wires checked electrical connections checked voltage and amps checked voltage absorption system compressor capacitor is low I suggested replacing now to avoid future problems also to make the unit operating I gave quote for customer accepted replaced the voltage absorption system tested start up and unit began operating very smoothly without any hesitating or lag checked electrical connections checked voltage and amps checked condenser drain checked air filter checked blower motor measured supply and return air temp measured EWP and LWP also water temp unit operating normal at this time. Collected $232.60 for voltage absorption repair on C.C
Upon arrival, found water heater to be well over average life expectancy and not up to code (no pan or expansion tank). Recommended and quoted for replacement. Office to follow up regarding estimates as customer was unavailable to discuss further at the time they were presented.
Fall pm on 09/27/19 On arrival set unit to call for heat measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked air filter recommended unit air filter needs to be replaced checked blower motor is very bad condition is a lot of dust in blower wheel checked evaporator coil is building dust in coils checked the duct is a lot of dust checked condenser unit outdoor checked electrical connections checked voltage and amps checked compressor capacitor checked coil is not in good condition outdoor coil needs to be cleaned checked pressure and temp and they are ideal indicating zero leaks checked all other electrical connections unit tested unit operating normal at this time. Highly recommended #1 duct needs to be cleaned #2 Evaporator coil needs to be cleaned #3 blower motor wheel needs to be cleaned #4 outdoor condenser coil needs to be cleaned #Uv Lights needs to be installed ASAP.
Ground all gas lines due to old fires happened. We have a ground in the same room as the manifold. Water heaters look old. Would suggest doing a flush of the water heaters just to make sure they are clean and ready to use when ready.tie in water filtration system. Will need to test water to see wether or not we can eliminate uv protection. Also wants to eliminate pelican water technology. Gas main coming from tanks outside is 1/2 copper then increases at the entry point to 1â€. Would also like an estimate to change line if btus are drop to much. I will ground manifold to the breaker panels in the same room. 100 for deposit and will collect the remaining 155 when job is complete.
When I arrive customer Explain to me about his HVAC system having a leak. customer asked me to diagnose and search and find leak customer was worried about leak in line set running through wood frame. after that I started to get my tools together to do a leak search on the first floor unit call for cooling to performed a leak search on copper line sets that was visible between Joints beams this home has no drywall most other copper is visible. I found first floor outdoor condenser has a leak on both of the valves also the same unit as a lock rotor. amps are 145 Customer then asked me to run second outdoor unit that cools the second floor of the home the unit has no leak but I recommend that the R22 Freon in that unit Second floor level. upgraded to the replacement Freon 427A And then customer second request was to check what damper is not allowing two are the registers to not have airflow I found out later on zone 2 there is power going to it but it will not operate, I man

On arrival found bad indoor blower motor.recommended replacing system due to age of it (12 years ) .customer is sechduled for a free estimate tomorrow
Up and n arrival replaced indoor coil. Pulled recovery, pressure tested, put it vacuum, charge with 410A . Cleaned humidifier . Checked unit for operation, unit operating excellent at this moment
At start up the unit can begin to operate and turn off on high head pressure. Sometimes the unit resets and refrigerant pressures are normal with 10 degrees subcooling and 20-24 degree delta temperatures across the evaporator coil. The blower is operating as well as the loop pump. The txv valve fails to open or gets stuck periodically rendering the unit non operational. Customer approved the repair to replace the txv. $586 due at time of completion. I completed a parts order form. The office will reach out to the customer to schedule return. Customer asked for 08/16 or 08/17 as I explained in another form.
On arrival found system low on refrigerant,customer approved recharge only .added about 1 lbs of 410 a ,unit operating normal at this time
On arrival found frozen coil .turned it off and informed custmer to call office to reschedule
Unit #2 cube in the basement was not operating because it was locked out on â€œhigh pressureâ€ fault code. Prior to finding this, I had gone into the attic and the drain switch was closed and the blower was operating sending y1 & y2 to the cube. As soon as I observed the lockout fault I called Water Furnace tech support and spoke with Mike. We spent 20 minutes running checks on the system after I cleared the fault code and the unit was operating. 3.5 psi pressure drop 11.8 loop delta .92 amp draw of the pump Discharge pressure: 232 High pressure switch was closed After running through the diagnostics, Water Furnace advised to observe the unit. The call is on record with WF. There was not enough evidence given or observed by WF to replace the circuit board. Unit operating normal. I called the customer because their spouse had to return to work while I was still on the phone. I explained as best I could what had happened and that it is not related to any maintenance or previous se
Unit #1 had faulted on â€œcondensateâ€ 13 times. The pan was full of water. I took the clear tube out from within the unit and used a large pipe cleaner flue brush to completely scrub the sides of any growth. The drain tubing was like brand new when I was finished. I also cleaned out the pan and blew out the pvc drain line. I reconnected everything and poured water through it to check for proper drainage without leaks. I cleared fault codes from the unit and ran the unit from the thermostat. Unit operating normal. Customer approved the repair. I asked the office to please call the customer for payment because the cellphone reception was very poor and wouldn't call out or dropped the call.
I started by checking blower run capacitor and cleanliness of the evaporator coil and blower wheel. I then went to the outdoor unit and found the fan motor side of the dual run capacitor was open. The unit most likely ran without the fan and tripped on high pressure. I replaced the voltage absorption system and then applied my refrigerant gauges and temperature probe to the discharge line. I was checking for subcooling. I did increase the indoor blower speed to high and after doing that I had normal operating pressures for r22 system with 8-10 degrees subcooling. The delta temperatures across the evaporator coil were 20-22 degrees. The suction pt was 40 degrees. The unit is operating normal. Customer signed up for service membership on the main level unit only. Customer declined adding the upstairs heat pump for the time being. Customer can always call the office and have it added for an additional $12.50 per month.
I recovered the refrigerant first then closed the service valves to keep the cube section in a vacuum. I could tell from the amount of refrigerant recovered that the unit was over charged. I removed both schrader valve stems to release residual pressure and the went into the attic and removed the txv and replaced it with brand new OEM part. I then went to the cube and pressurized the system with 325psi dry nitrogen and let it hold pressure. I then flushed lineset from high to low side. I installed new valve stems and let the vacuum pull the lineset into a <500 micron vacuum. I then added 7lb 8oz of refrigerant, a full pound less than what was recovered and then opened the service valves, properly backseating them. I then turned the thermostats to cooling mode. I had 20+ degree delta temperatures across the evaporator coil in first stage cooling mode, 12 degrees subcooling and 6-8 degrees superheat. Refrigerant pressures were great and the cooling across the coil was really the best Iâ€
I cleaned the condensate pan and drain lines and ran hot water to flush the debris and to check for proper drainage without leaks. The EAC pre filters were very clean. I operated the unit on second stage cooling mode. I reset blower speeds from 2,5,7,8 to 2,6,8,10 and informed the customer why I had made this change. I checked the electrical wiring and electrical systems, all ar within specification except for the compressor run capacitor, which was replaced. I confirmed proper flow rate and heat of rejection and then pressurized the ground loop to 65psi. Unit operating normal.
Service call on 05/28/19 On arrival set units to call for cooling unit B&C is running but Unit A is not I checked electrical connections checked voltage and amps I found error code E10 compressor log out I checked compressor capacitor also checked contractor everything is fine reset it turn on the unit the error code is go away the problem customer explained to me the have thunderstorms Saturday that was the problem they are out of power I checked all other units measured supply and return air temp measured voltage and amps inspected electrical connections checked drain checked compressor capacitor units operating normal at this time.collected $215 on CC $99 trip fee and $116 diagnostic fee.
Txv in the attic is not opening properly and causing the head pressure to build up and turn the compressor off. The unit is cooling as I checked it the other day, 4psi pressure drop and 10-12 degrees heat of rejection. The refrigerant is restricted at the valve. The valve needs to be replaced. I made an estimate for the work and completed a parts order form estimate with pictures of the Lennox evaporator model and serial number and a picture of the part number on the valve. Customer tried to reach their partner to discuss but they were unavailable. I told the customer that diagnostic charges paid today could be credited toward the repair.
Replace controller board in the cube unit #1. I replaced the control board and operated the unit on second stage cooling mode. I went into the attic and cleaned the drain line and ran hot water through it to flush the debris and to check for proper drainage and pump ejection. I replaced the upstairs filter with one provided by the customer. Unit operating normal. Customer paid $300 deposit which is not showing up on the invoice. Customer has paid the repair in full. The office will have to correct this invoice.
Donna was supposed to have gotten re approval for the repair from the customer. Customer gave me approval the night I was here fixing refrigerant leak but I guess the estimate was not signed. I am pretty sure it was signed. I went over the repair and part credit with the customer. Customer still is entitled to refrigerant credit from all repairs and labor allowance for this repair. Customer spoke with Darlene regarding finding out the labor allowance but never got an answer. Customer not here now and wants to pay through the office in the morning. I replaced the compressor and refrigerant filter drier, flushed with nitrogen and pressurized the system to 250psi. There are no leaks. I vacuumed to 500 micron and charged the system. Unit operating normal.
I performed the maintenance on the hydronic system and switched it from heating to cooling mode. I cleaned the condensate drain line and ran water through it. I pressurized both ground loops and checked the electrical wiring and electrical systems, all are within specification. Unit #2 is operating normal. Unit #1 is the geo split system with the cube in the basement and an air handler in the attic. I operated it on cooling mode and the loop pumps never got powered from the relay inside the unit. The fuses are in tact. The control board is malfunctioning and needs to be replaced. I completed a parts order form and customer paid 300. Need to clean the drain upstairs and finish maintenance on this unit when we return. I checked the electrical in the basement but not in the attic.
The technician left the disconnect in the â€œoffâ€ position. The other units were operating. The unit for the upstairs began cooling once power was restored.
