System is operational at this time.

Upon arrival tech was shown AC #1 was not running, condenser fan was slowly spinning but compressor was not running. Inspected system and found compressor contactor getting 24v. Tech noticed the black wire for the condenser fan motor was put on the 24v coil and not on the T2 side of the contactor. Tech corrected wiring and turned system back on and compressor was still not running. Ohmed compressor and found it locked out on internal overload. Use water hose to cool down compressor until it came back on. Checked pressures and amp ratings and everything was within specs. System is back operational at this time.

Upon arrival tech was informed there was water coming through the wall I front of the bathrooms and customer wanted to check and verify it was not coming from a near by hvac system. Tech inspected above the ceiling and on the rooftop and dit not find any reason to believe that water issue is coming from system due to not system being approximately 8-10 feet from damaged area and no signs of water trail above ceiling grid.

Came to clean out drains for maintenance but I was informed that another company came yesterday and did the cleaning.

Tech preformed CMA FULL SERVICE on 2 Split Systems, 2 Package Heat Pumps and 1 Gas Package Unit. After servicing Split System #1 Tech found low pressures and low Delta T. This indicates system is low on refrigerant due to possible leak. Tech electronically checked coils for leak but did not find leak at this time. Tech recommends preforming a Level 2 Leak Search before any further action be taken. Tech has attached estimate to invoice for cost of leak search. Tech found Package HP #2 not operating even though thermostat stated system was on. With further inspection tech found that thermostat has failed and tech recommends replacing thermostat. Tech has attached estimate to invoice for replacing thermostat and programming. All other Systems are operating at this time.

Techs found open float switch due to full drain pan caused by evaporator coil freezing over. Found blower control board in non-functioning condition; replaced once approval was given. Upon further examination, techs observed the system running high liquid pressure due to dirty condenser coil. Will schedule coil cleaning on separate date. System is operating at this time.

Tech removed wet insulation at bottom of return box at system 2 and added new insulation. Sealed with FSK tape. Install warranty.

Tech returned to replace compressor. Recovered all refrigerant from system, removed compressor and purged system with nitrogen. Brazed in new compressor and pressure tested system.

Upon arrival tech was informed Gas Furnace #2 had a strong gas smell inside the rooms the furnace feeds. Tech inspected system and suspects the gas valve is bleeding through causing the gas leak. Tech tested the heat exchanger with manometer by turning the blower on and checking for a pressure reading and got a .02-.03 reading indicating a potential crack in heat exchanger. Customer wants to wait on replacing gas valve and get quote for new system. Informed office to get field supervisor involved. Gas line is left off at shutoff valve for time being and estimate was emailed for replacing valve. Customer stated they will call us back if they decide to do repair.

Upon arrival tech found condenser receiving a 24v call for cooling but not running. Found breaker tripped, compressors wires rubbed through against refrigerant line and shorted. Tech isolated compressor and tested windings before attempting to repair wire and reset breaker. Found compressor to be shorted to ground. Compressor is failed, informed homeowner. Customer stated they will make a decision and call.

Techs found water dripping from return side. Re-leveled air handler to set drain pan pitch in proper direction and removed water from drain pan. Return insulation is saturated and needs to be redone. Will require 3x3ft piece of insulation. Ceiling tiles are stained as a result of the water leak; customers stated they will replace the tiles. System is operating properly at this time.

Tech found od fan was running but compressor was not. Upon further inspection tech found compressor shorted to ground but condenser has a 60 amp breaker. Contractor wires were burnt and dark but breaker never tripped due to being a bigger size. Tech informed customer on findings and recommended replacing due to age and repair cost she declined due to not having funds and renting. System is down.

10" SUPPLY DIFFUSER WITH MANUAL DAMPER

Tech found 2 month old RunTru split system not running due to aux pan full of water and aux pan float switch turning off power to thermostat. System is two months old and installed by someone else. AHU is lopsided, sitting on bricks in auxiliary pan. Drain slopes towards back of AHU. Slopes away from drain. Drain line runs nearly flat the entire length of attic. There is no primary pan switch. Return box is only a few inches wide mounted to the back of AHU. See picture. Supply plenum is kinking return flex duct behind filter grille. System needs to be leveled in attic for AHU to drain at all. This would require two people. AHU also needs to be raised about a foot higher to make gravity drain work. Drain would also need to be resloped and strapped every four feet. A better solution would be to install a condensate pump with available 120 outlet already in attic. Tech recommends condensate pump instead of gravity drain in this attic. Tech also recommends raising supply plenum a few f

Performed CMA Full Service on 1 split System Gas Furnace / AC. Systems 1 and 3 are currently down. Space only being cooled by system 2. System 2 does have a leak in the evaporator coil and has had the refrigerant topped off in the past. Delta t today was hovering around 12-13 degrees which is to be expected with the other 2 systems down. Per manager on duty, there are currently negotiations going on in reference to all 3 systems on whether to make repairs or replace the systems.
