System heat did not come on due to a miswired vision pro Tech rewired under warranty no charge
Customer reported grinding noise from outdoor unit. Thinks it may be when reversing valve switches back and forth. Tech inspected system, recorded amp draws and refrigerant pressures in each mode, and tested defrost. Found no challenges with defrost or reversing valve. Couldn’t duplicate grinding noise. Tech heard no unusual noises from system. Tech found 7.5uf blower capacitor reading very weak at 4.35uf. Blower motor is warm to the touch. Tech found 5uf fan capacitor reading low at 3.9uf. System pressures are a bit low indicating system slightly low on R410a refrigerant. Reports system has been cooling fine this summer. Tech found one leak hit on bottom left corner of indoor coil. Could not duplicate again after leak searching several minutes. Tech recommends replacing both weak capacitors and getting system on preventative maintenance. Quoted prices for capacitors and leak search. Customer declined leak search for now. Approved PSA, capacitors, and adding refrigerant. Tech a
System 4 was cooling in conference room on arrival. Indoor coil has thawed. Indoor coil is clean. Insulation in return is damp from ice melt. Permanent 20*20 filter looks clean. Tech uploaded pictures of refrigerant pressures. Subcooling is measured at 10 degrees. Design subcooling is 13. Indoor coil temperature is about 36 degrees due to low outdoor temperature for cooling mode. Tech suspects filter may have been dirty. Cycled power and allowed system to cool for ten minutes. Uploaded running pressures. Found no challenges. Leak searched indoor coil. Found no refrigerant leaks. Changed blower from speed tap 2 to speed tap 3. Let Roger on site to clean washable filter every month and let us know if there are any further challenges. No charge for CMA follow up.
PERFORMED CMA FULL SERVICE ON 6 SPLIT SYSTEMS, 3 MINI SPLIT SYSTEMS AND 2 GAS PACKAGE SYSTEMS. SPLIT SYSTEM 4 EVAPORATOR COIL WAS FROZEN OPEN ARRIVAL, DIAGNOSED SYSTEM FOUND GOOD AIR FLOW, ALSO FOUND A LOW DELTA T READING OF 11. READING ON DELTA T SHOULD AT LEAST BE 17, WHICH INDICATES SYSTEM IS LOW ON REFRIGERANT. THERE WILL BE A DEMAND TECH COMING SOON TO ADD REFRIGERANT IN SPLIT SYSTEM 4. GAS PACKAGE UNIT 2 HAS WATER IN THE BOTTEM OF DRAIN PAN, THE WATER IS LOWER THAN THE DRAIN LINE EXIT POINT OF THE UNIT. ALL OTHER SYSTEMS WERE OPERATING PROPERLY.
Tech waited for the costumer to unlock the mechanical room to perform diagnostics. Found the system operating with no delta T, only room temperature air. Compressor was not running due to a failed 70uf dual run capacitor. Replaced the dual run capacitor and compressor started up without challenges. Tech noticed the refrigerant levels slightly low, tech added 1lb of R410a to aquired proper refrigerant Levels for cooling. Due to the location of the condenser(enclosed brick wall by the dryer vent exhaust) and heat load in the laundry area, slightly high head pressures will be expected, condenser coil is clean. Delta T of 20 degrees was aquired after the repairs. Tech informed Tara of the findings and repairs and approved. System is back cooling.
Tech found primary drain line clogged, tech cleared drain with nitrogen and tested for proper drainage. Tech also vacuumed out water from auxiliary drain pan. System is back up and draining/cooling properly. No charge per office.
Tech returned to replace txv tech pumped refrigerant back into system and replaced txv tech pressure tested unit held 230 psi tech pulled down to 300 microns unjt is operating properly at this time with a delta t of 20 77 return 57 supply tech did find issues with supply vents some being 3 degrees off from each other customer has supply box with 6 lines then a 14 in flex to another supply box with more lines off tech found one side of the house vents blowing colder by 3-4 degrees then the other tech informed customer to keep a eye out on it if issues arise again we will need to return to pull refrigerant out and pull a vacuum then add new refrigerant as of right now system is operating properly
Inspection found the furnace doors were install incorrectly. The burner (louvered) door was installed over the blower compartment (pictured). This was allowing outside air to be pulled into the system, increasing humidity to the house. Tech corrected the door configuration, inspected the evaporator for proper installation. Tech fixed challenge with door access to coil by securing supply plenum under coil door instead of over door. Refrigerant pressures measured were found to be out of range. Suction pressure is low but superheat and subcooling are high, and system is not cooling correctly. Tech diagnosed the TXV faulty on the new coil. Jerry is placing order for new TXV, will contact customer when repair ETA is known. Warranty.
Tech performed CMA filter change on 6 split systems, 2 package units, and 2 mini splits. Tech replaced all filters in both package units, and washed all filters in mini splits and split systems. Tech has attached filter change report to this invoice.
Tech returned to check for leaks on recently installed system. Tech leak checked entire system and was unable to find any leaks. System pressures are within specs, humidity level is slightly high inside house, customer stated she is leaving to go out of town for a few days and will call when she gets back if humidity level is still high in home. System is cooling properly. Tech also educated customer on thermostat operation.
Trane 3.0-Ton Heat Pump & Evaporator Coil
Performed ESA, homeowner extended PSA. Homeowner stated system not keeping up. Tech found leak in evaporator coil. System is 18 years old and takes R22. Tech scheduled a field supervisor to come out.
JACOB AND JUAN REPLACED A 5 TON GOODMAN AIR HANDLER
Tech returned to replace 1/4 hp 825 rpm once replace unit started up no issues amp draws are within specs door of ah room was locked customer did not have key tech told maintenance flip breaker when they can get key to open
