Tech was great
Called Dibiase in the morning - Kurt and crew were here to fix leak and were finished PDQ with report and invoice ($0) issued by 2.15pm. Kurt took the time to explain the issue and what corrective action they had taken. Can't ask for better.
Dibiase is top class (every time). Dave was great. He was creative in solving problems of a difficult installation and really profession in the execution. And the crew were fully cognizant of Covid precautions. Full marks.
Chris was professional and personable. He performed the Fall HVAC maintenance visit in a timely manner and advised that all was well. I am very please with Chris and DiBiase
Dibiase are phenomenal - customer service is exceptional. Technical staff are really professional, fully in tune with of customer needs, courteous and cognizant of Covid precautions. I won't go anywhere else.
Performed cooling maintenance, checked media air filter ok. Blew out condensate drain. Checked voltage, amperage and electrical connections, measured capacitor values. Started air conditioner, checked refrigerant charge and temperature drop across coil.
Disconnect power to unit and remove existing Compressor from unit. Install new OEM Scroll Compressor and braze connections with nitrogen. Pressure test system with Nitrogen and leak test compressor fittings. Evacuate system to below 500 Microns and weigh in manufacturer's charge. Put system in cooling mode and measure refrigerant pressures. Add additional refrigerant to system charging by Subcooling/Superheat. 6/21/21: Compressor replacement for 2 Ton Ruud AC system Unit 6201. Removed existing compressor. Brazed new compressor while purging with nitrogen. Pressure test 365PSI passed. Evacuated system to 480 Microns. Using AtWater's refrigerant charged system. Factory charge 89oz. Added additional refrigerant until system was ooerating designed subcooling/refrigerant values. 363HI/140LO. 11.5 SC 18SH. 21F temp split. System is operating well at the time of this service.
Reclaimed and removed old heatpump and airhandler. Installed a new amana airhandler in existing location. Installed a new HE filter on to return side. Installed a new ez trap that is wired into unit, flushed copper lines and brazed and leak checked with nitro and soapy bubbles. Installed a new amana heatpump on a new level plastic pad with snow feet underneath. New disconnect box and electrical wiring to unit. Tested equipment in all modes.
Evaporator coil replacement for Unit 3305 air handler. Made all necessary piping connection. Pressure tested to 300 PSI. Evacuated system to 480 microns. Charged system factory charge plus 13oz. (110 oz) R410A. Final temp split 19F. Subcooling 11.5; Superheat 9.5. 343HI pressure/146L0Pressure. Outdoor ambient 88.5F System is operating well at the time of this service.
Went up on roof to outdoor heat pump. Hooked up gauges and had no refrigerant in the system. Troy supplied a bottle of 410a. Started adding refrigerant and found that there was a hole straight through the compressor. Heat pump will need the compressor replaced to get system back in operation. Will let our office know the findings and let them know when we can replace the compressor.
Customer has to reset outdoor unit breaker for the unit to work, check operation of system and found error codes on outdoor unit consecutive low pressure Faults, reset unit and check operation, ran unit for 40 mins monitor pressures and airflow ok 220/120 with 8 sub cooling and 6 super heat supply air 45 return air 65 check low and high pressure switch wiring ok, did not find any problems in todayâ€™s visit, if happens again we will contact customer support for further troubleshooting
Found system low on charge. R-22 pressures were 129/28 with 0 subcooling. We were out in April and refrigerant pressures were ok. System must have a decent refrigerant leak. Explained to homeowner the process is if he was going to jut add charge and leak dye to the system this will help locate the leak but if leak ends up in indoor coil, coil will be $4000 to $4500 to replace. Provided estimate to add refrigerant with leak dye. Heat pump system is a 2004 and highly recommended to replace heat pump system. Set up appointment with office to have bill come out to give an estimate. Homeowner also showed me a room upstairs that never has cooled right and was curious about a ductless system for this room.
Building A 2nd Floor unit close to 207. Bad board. Building B Secondloor unit CLL me to 235 no line voltage to contactor (check breaker). Buildingng A Corridor East 2 unit undercharged; we charged to 5 subcool. Building B 2nd floor unit corridor West Drain Oan filled with water (maintenance staff will take care of it). Building A level 4 close to appt 407 verifier bad stat.
Performed ac tune up attic system, check electrical low and high ok filter ok flushed drain and add tabs ok check split, noticed some bacteria and mold forming inside air handler, informed customer check outdoor unit refrigerant pressures capacitor and cycle unit ok emailed proposal for air purifier installation
Replaced blower motor Appt 2302. Tested system operation. 20F temp split (78F-58F).
Found condenser fan not operating. Determined need that a burnt relay in control board. Switched with control board from corridor unit 1 "CC1". Tested system operation. 18F temp rise. Hi pressure 353 Lo pressure 131. 6Â° subcool. Will order control board and schedule time to return to complete install of control board for unit CC1.
No A/C found indoor blower running but no outdoor, check operation of compressor and fan motor, fan motor is open in overload, also capacitor reading zero both ends hermetic and fan side, quoted for repsirs called Jay and he approved repairs, after cooling down fan motor and replacing capacitor check operation of air conditioning system r22 pressures 220/75 with 30 super heat and 8 sub cooling manufacture calls for 10 sub cooling indoor txv indoor temp 80 outdoor 90 F supply air 62 return air 79 F 17 degree split
Performed cooling maintenance, checked media air filter ok. Cleaned eztrap and drain. Checked voltage, amperage and electrical connections, measured capacitor values. Started air conditioner, checked refrigerant charge and temperature drop across coil.
Installed new t10 thermostat and programmed to system. Relocated upstairs master bathroom vent to living room ceiling. Checked air flows on system then balanced with dampers. Rechecked airflows and static pressure. Will need to talk to customer about relocating another supply and terminating another one. Airflow has been improved in key areas.
Performed ac tune up unico high velocity unit, check electrical low and high ok replaced filter, flushed drain test pump ok, outdoor unit refrigerant pressures capacitor and contactor ok supply and return air ok 68/45 cycle unit ok
