Performed inspection on both units. Cleaned filters. Checked cleanliness of blowers and coils. Checked electrical components. Ran aux heat and HeatPump heat. Also ran ac shortly. Checked amp draw of compressors, od fans, and blowers. Tried to run defrost but itâ€™s too warm outside to do so. Let systems satisfy thermostats. Units operating normal.
Remove condensing unit.
On arrival set thermostat to call for heating Measured return temperature, supply temperature, EWP,LWP,EWT,LWT,amps, and voltage. Inspected electrical connections, replaced Aprilaire filter provided by customer, blower wheel is clean, evaporator coil is clean, cleaned condensate drain pan, and. I also explain to the customer the benefits of installing a wet switch and having a duct cleaning. Unit is operating normal at this time.
Upon arrival we spoke with receptionist and she wasnâ€™t aware we were coming. Started Pm but found we need access to Accounting office above Yoga studio (Keiser and Keiser CPA 410-494-6900). Informed office.
set hose Bibb today and ran waterline need to comeback when floor is prep is done to set shower pan and test drain lines
Performed Inspection on all RTUs. Replaced filters. Flushed out drains. Inspected cleanliness of blowers and coils. Checked capacitors and contactors. Tightened electrical connections. Inspected heat exchangers. Systems were in ac mode so I checked operation and made sure thermostat satisfied. Only issue is with smoke alarm for top floor system. Customer has been told to contact Fireline for this.
Upon arrival I was told that top floor ac wasnâ€™t working and thermostat not displaying current temp. Found thermostat giving E1 and E2 faults, ac fault and heat fault. Went to unit on roof and found no faults at all. Normal voltage going to unit and thermostat. Found no voltage returning from smoke detector, wired on terminals 24v(red) and EStop(White) jumped out terminals and system started up, thermostat faults gone. Set up ladder to find smoke detector in supply is in fault condition and wonâ€™t reset. Since it is wired to the building automation system I cannot touch it, customer needs to call Fireline. Smoke detector is disconnected at unit, once repaired we just need to reconnect wires to 24v and EStop.
Fall pm. 9/17/19 On arrival set unit to call for cooling Measure supply measure return check voltage and amps and inspect electrical components and recommend cleaning coils on the indoor and outdoor unit condensation line was clogged. customer supplied a new filter replaced, then I call for heat check the delta T and return 115Â° return air 75
Replace Warranty TXV and filter drier, recharge with new refrigerant. Upon arrival I started by removing all refrigerant from the system. Used torch to remove old txv from unit but had to cut out equalizer tube because torch wasnâ€™t taking around black coil insulator covering pipe. Sanded down each end and used copper coupling for equalizer. Used torch to braze in new TXV and close equalizer coupling. Blew nitrogen through system while doing so and kept TXV covered and away from heat. Pressurized System to 350psi nitrogen and held while I insulated suction piping and sensing bulb. Pressure held, no leaks. Removed nitrogen and vacuumed system down to 500micron and held. Put panels back on doors while vacuum held, no leaks. Added factory charge of 55oz to system then restarted And ran AC. Total charge 70oz of 410a. Matched Superheat and subcool with spec sheet, normal compressor amp draw, normal delta air temps, normal loop heat rejection. Unit operating normal at this time.
Replace 75 gl power vent water heater. Customer is just being proactive on water heater to make sure she doesnâ€™t run into an issue with it. Will need also a helper as it is a power vent.
21-Tuneup special on 08/29/19 On arrival set units to call both heating and cooling modes checked unit air filter I sanded the flame rectification probe and checked burner arrangement the ignitor homes out to be in good condition all other electrical device in side the furnace checked blower motor measured supply and return air temp measured voltage and amps are within specifications. In cooling mode I checked the pressure and they are ideal indicating zero leaks in the system checked voltage absorption system checked compressor capacitor measured subcooling and superheat unit operating normal recommended duct cleaning and uv lights installation
Upon arrival I found thermostat reading 73, set for 73. Lowered temp to 70 and checked operation. WSHP is running normally but found previous fault for low pressure. Checked filters and they are extremely dirty, removed them and continued to check operation. Found no issues with unit, other than filters needing to be replaced. System uses fresh air duct that pulls in outdoor air, with filters being so dirty, Return was forced to pull more air from outside. Because today is only 75, unit didnâ€™t have any issues running. Called office and they told me to go pick up filters and return to install. Went to Loweâ€™s and picked up (2) 20x20x1 filters, returned and replaced them. Unit is operating normal.
Upon arrival I found system set for 75 and currently at 75. Dropped temp to 70 so system would run in 2nd stage. Found low delta but normal refrigerant pressures. Measured Superheat and subcool and found them to be relatively normal but I had low heat rejection on the loop. Suspecting txv to be an issue so I removed bulb and stuck it in hot water, no change in refrigerant pressures or temps. Put bulb back onto pipe and has no change in operation. Called Water Furnace and spoke to Dave. He confirmed my suspicion that the TXV is not metering and needs to be replaced. Part number TXV 33P609-01, Filter drier 36P500B01, WF case number 508976. Quoting customer to replace, unit under warranty until Dec 2020. Customer approved repair and would like first call when part is replaced if possible since contractors on site leave at 3.

When I arrive customer walk me to outdoor condenser unit I checked voltage 240v I checked 24 V everything is good and then I check the air handler up in the attic to check voltage240v i check 24 V come to find out it was a loose wire on 24 V Outdoor condenser unit came on as soon as I found loose wire.At air handler. Customer is thinking of becoming a member $16.66 per month for one year but waiting to square up with the company that installed the equipment. Pictures were taking up data plates.
When I arrived I started prepping to remove damage condenser outdoor unit. We had rain doing our installation of the condensing unit but I managed to finish my installation process I finish all my steps turn unit to 72Â° Uppalevel home is calling now delta T 57Â° return 75Â° Or finish pictures were taken Of data plate and unit
Compressor starts up but does not pump the refrigerant and operates 15-30 seconds before turning off, most likely on internal overload. The compressor has to be replaced along with the filter drier inside the condenser. I took pictures of the unit and compressor data plate and transferred the information onto a â€œpart order form.â€ I completed a â€œfollow upâ€ form to alert the office to contact the customer as soon as the compressor is available. Customer has no ac upstairs which is where the bedrooms are located. I pulled the disconnect outside to keep it from trying to operate. Unit not operating normal. I called the installation manager to let them know the situation as well.
Upon arrival found tub clogged. Will perform a bio clean within drain and test drain when done. Declined walk around due to her selling the house soon and will call back in to schedule a review before her inspection. Upon further review found stopper also clogging the drain. So I eliminated the stopper and bio cleaned and system is working once again.
When I arrived I checked thermostat I checked air handler and then I checked the outside unit. the unit had a fault of a lock rotor I reset thermostat. So then 5mins later unit started up the compressor kicked on and off seconds at a time. I connected my clamp meter is reading 64-68Amps and would not continue to run, Just the fan motor only. I open caps to see if valves were close they were all open but I noticed the low pressure valve was bubbling with oil.... pictures was taking of unit and data plate. This unit has a bad compressor with one leaky valve low pressure side.
Service call on 08/05/19 On arrival set unit to call for cooling measured supply and return air temp no DT checked electrical connections checked voltage and amps checked air filter checked blower motor checked outdoor condenser unit is not running I reset the unit the compressor is comes on but the fan motor is not I checked compressor capacitor also defrost bord bc the blower motor wires is going to that bord I suggested to replace the blower motor with blower blade and defrost bord I explained the customer she needs time to decide what she wants replacement or repair she is going to call us back after she is talking to her husband unit turn off from disconnect box outdoor unit is not operating at this time. Collected$89 dispatch fee and $124 for diagnostic fee total $213 on C.C
I cycled the outdoor unit on the roof several times from the thermostat and it operates each time with normal operating pressures. The air handler was inaccessible because the upstairs office occupants were not there despite me arriving at 2:30. I confirmed 58 degree supply temperatures. I set the thermostat to â€œholdâ€ and showed the customer. Perhaps there was some scheduling conflicts that will be overridden now and the unit should hold the set point.
On arrival removed existed check valve then installed a dual check valve per work order . Office will create final invoice (per office )
On arrival found system slightly low on refrigerant.added 0.8 lbs of r410a .checked delta t 20 .unit operating normal.
Customer has a compressor on the roof with open windings. Crane could park in the back. 60 feet out and 24 feet up. Condenser on the roof is 200/230 volts, 1 ph, R22 5lb 8 oz with a MFR date of 8/2006. Reclaimed the refrigerate from the system. Removed the bad compressor. Installed the new factory compressor. Made all wiring connections. Connected the refrigerate lines. Pressure tested with nitrogen and checked for leaks. Removed the nitrogen charge and put the system into a vacuum. Charge the system with R22 refrigerate per name plate. Left with pressures at 68/215, sub cooling at 9. Space temperature down to 74 degrees.
Checked all the roof top units. Found no sign of any drainage problems.
