Weekend service call was prompt. The tech was kind, courteous, well spoken. A part needs to be ordered, so, I have to wait to comment on the outcome.
Service Call on 08/16/19 On arrival the air handler drain pan is full of water open the air handler Evaporator coil cabinet open the blower motor cabinet I put water is backing up the drain pipe is clogged checked outdoor unit pressure and temp they are ideal indicating zero leaks checked subcooling and superheat unit operating normal I gave quote for customer closet tha drain line with nitrogen and cleaned the drain pan customer accepted cleaned the drain pan pressure drain pipe with nitrogen tested water going out normal installation the Txv also customer has problems with humidity the supply duct is not insulation right I gave quote for customer to reinsulation he will think about that I checked the unit set the unit to call for cooling measured supply and return air temp measured voltage and amps inspected checked high voltage and low voltage wires checked all other electrical connections inside the airhandler unit operating normal at this time. Collected $593 for cleaning the drai
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.
Install Pressure Reducing valve with dual check and water meter to maintain pressure. When testing backflow operation I found some water bleeding thru check valve and back into fresh water hose. We cannot have Loop water back feeding into house water so I had to leave ball valve closed on water meter. Informed customer on site that if pressure drops below 40psi, open up hand valve for a second to let pressure rise to about 50psi, then stop and keep closed until we replace check valve. Loop pressure left at 50psi. Informed office that we need to return.
Upon arrival I was told Geo systems were having a hard time keeping up. During diagnostics I went to units in basement and could hear noise from loop pumps. Packaged system running, cube #2 running, cube #3 locked out on high pressure. Found loop pressure in the negative and incoming water temps at 85 degrees. Pumped up to 60psi with cold water to help cool loop down. After about 30 minutes of run time loop pressure dropped down to 30psi. Pumped back up to 60psi and it dropped to 50psi in a few minutes. Suspecting customer has a leak in the loop because of negative pressure and darkness of water. Found no puddles or signs of water anywhere on loop pipes that are accessible. 3 systems, 2 flow centers, and 1 loop. Would like to return to install pressure regulating valve onto flow center to keep loop pressure at a constant and monitor how much water has been added over time. Found all 3 systems cooling under normal water flow conditions.
Upon arrival I spoke with Matt because customer wasnâ€™t going to be on site, he explained builder would let me in. Customer explained that the other day he stopped feeling air coming out of middle bedroom vents and all other zones are blower harder, airflow not balanced therefor not satisfying thermostat. Found both zones off upon arrival. Turned on and found middle bedroom zone damper actuator signaling open but no airflow. Removed actuator and found set screw not tight on shaft, not spinning damper open. Tightened screw and tested. Damper opening and airflow normal. Then I checked each vent and found 2 bedroom takeoffs werenâ€™t tight against duct, letting air bleed out. Finally I removed air bleed vent from duct and sealed with insulated metal. After doing so airflow increased to all zones. Verified normal airflow to all vents. Builder then approached me about condensation on ducts in garage. I inspected system to find 413 filter very clogged with dust and debri from construction.
To fix sewer gas smell in shower drain needs to be increased to proper size supported along the wall and a vent needs to be added in between the two showers. Washer and dryer need to be pulled out and drywall needs to be cut out to find vent to tap into. Also had to redo shower drains , pipes werenâ€™t glued together and falling out of shower basins
Customer had recently replaced the air filters in the 2 Geo split systems I serviced. The filter for the Carrier heat pump is washable. I vacuumed the surface dust off it, but it is very clean anyway. I operated the 2 WF systems on second stage cooling mode and confirmed proper flow rates and heat of rejection for each system. I pressurized all the ground loops to 65psi standing pressure. I checked the electrical wiring and electrical systems, all are within specification except the compressor run caps for both WF units were well below spec. They were each replaced in #3. I confirmed 18-22 delta temperatures across the evaporator coils for all 3 units serviced. The Carrier unit had electrical systems all within specification. I went around and vacuumed each drain line and flushed with hot water to check for proper drainage without leaks. All units are operating normal.
Performed ac inspection on all units. Replaced filters. Flushed out drains. Inspected coil and blower cleanliness. Inspected capacitors and contactors. Tightened electrical connections. Ran ac on all units. Measured amp draw and delta air temps. All units operating normal.
Compressor for the yoga office has open windings and needs to be replaced. Since the unit is R22 refrigerate, I recommend going to a 410A system. The yoga workout room needs the thermostat replaced. It is not working properly.
On arrival tested Drain ,no leaks,i then set units to call for Ac .checked system pressures .found unit slightly low on refrigerant.checked for any obsvious leaks .used soap to check all joints .no leaks ,found outdoor high pressure service port without a cap .installed new cap and added 0.9 lbs of 410 a .units are operating normal at this time
Upon, arrival cleaned evaporator coil for downstairs system. Customer renewed service agreement for both systems. Preformed tune up on both systems. Downstairs unit operating to specs, compressor capacitor at bottom of range, will need replacing soon. Upstairs unit also operating to spec accept for compressor capacitor which was below range. Suggested replacing and customer agreed. Replaced capacitor. Customer interested in ez trap for upstairs unit. Attached estimate.
On arrival found indoor disconnect was off ,tuned it back on ,system operating normal
On arrival found system slightly low on refrigerant,pressurized system to 375 psi ,couldn't find any leaks ,vaccummed system ,recharged it 6.10lbs of 410a.tested Txv ,fan ,checked coil,unit operating normal at this time .
Upon arrival I was told neither system was cooling very well. Top floor system noticeably worse than bottom floor. During diagnostics I called for ac on top floor. Went to condenser and put gauges on. Found low suction pressure and normal discharge pressure, suction well below freezing and pipe severely condensating. Went to furnace in attic to find evap coil frozen solid. Needs to thaw before diagnosing. Then I went to main floor system and called for ac. Put gauges on and checked operation. Found normal operation, system with good refrigerant pressures, normal Superheat and subcool, normal delta air temps at Evap coil. System not keeping up because top floor system isnâ€™t cooling and airflow is restricted by frozen coil. Informed customer we will need to return to further diagnose top floor ac system. She asked if we could return tomorrow. Informed office to follow up with customer.
Condenser section is operational and suction line gets cold. Employee told me the blower does not turn on and the only access to this is through the upstairs office space which is closed currently. Also the unit serves the hot yoga studio and they will not let the technician troubleshoot while a class in progress. Need to return between 8-4 to gain access to the air handler section and try to cordinate when there is not a yoga class.
