Frame In Existing Motorized Dampers And Repatch Sheet Rock Around Dampers To Meet State Inspectors Requirements

Upon arrival landlord stated another company inspected system and stated it needed lots of repairs and had a major condensation leak. Tech inspected air handler and found no challenges, inspected spot of concern where bypass enters return and found it not sweating but may have been sweating in the past. Tech checked static pressure and found it to be testing to spec at .2 airflow and refrigerant pressures are good, drain line is not clogged and is draining properly, tech did find tenant had thermostat set to 66 and system was running continuously to try and hold temperature. Tech suspects this this is why ducts were sweating and tech recommended not setting it so low. Found no issues in condenser system is operating properly, spoke with landlord on finds and signed up for PSA.

PERFORMED CMA INSPECTION ON 11 GEOTHERMAL SYSTEMS AND 1 MINI SPLIT SYSTEM. TECH COMPLETED A LEAK DETECTION SEARCH ON ALL EVAPORATOR COILS, THERE WERE NO LEAKS FOUND. TECH CHECK CAPACITOR RATINGS AND COMPRESSOR AND BLOWOR MOTOR AMPERAGE, ALL CHECKS WERE INSIDE THE RIGHT SPECIFICATIONS. TECH COMPLETED FILTER CHANGE OF ALL SYSTEMS.

Performed CMA full service on 4 rooftop package units. There are a total of 7 on site, but only 4 are currently operating. Of the systems serviced today, RTU 3 is the only system with any major challenges. RTU 3 - compressor 2 on this system is shorted to ground. System is currently operating at half capacity. This will be apparent on days with prolonged heating or cooling needs. At time of testing, weather is mild and delta t is only getting to between 11-13 degrees. This is not enough temperature changeover to cope with high demand. Field supervisors office has an active proposal on this system and they are awaiting decision. All other systems tested are heating and cooling properly. No other challenges present. Note - RTUs 1,3 and 5 are not equipped with auxiliary back up heat. Filters - all filters changed and old ones disposed of.

Tech found thermostat satisfied at 73. Tech tested all capacitors, drains and refrigerant pressures. Capacitors were good and drain pan is empty. Tech found low suction and low superheat indicating low airflow. Tech made sure coil was not blocked and filters were good. Tech found blower on the low setting and changed to high. Pressures are good now and superheat increased. 17 degree delta T. Tech found blower board and the area around has signs of corrosion. If any of that gets into the board, it can cause issues with the relay. Tech quoted blower board replacement. AHU 8. System is cooling properly at this time and has dropped from 73 to 72.

Day of Labor to Meet State Inspectors

Tech found no low voltage to condenser. Upon further inspection tech found overflow safety switch was tripped due to clogged drain. Tech cleared out drain line and started to get good water flow outside. System is operating properly at this time. No charge due to recent maintenance.

Tech informed homeowner and would like a field supervisor email him repair versus system replacement. System is serviced and back on.

Install (3) Emergency Shut Off Switches To Existing Systems

Found system completely frozen from evaporator coil, to compressor. Damper motors/zone board, and blower are functioning. Filters are extremely clogged and possibly could be cause of freezing. Offered fee for thawing ice in order to further diagnose. Opted to let fan only run for the day to thaw system, and will change filters and call back if needed.

Remove And Reinstall (8) Motorized Damperes Install (5) Emergency Cut off Switches To (5) Existing Units

Tech performed esa on carrier split heat pump, found no challenges at todays visit.

(Downstairs) found water leaking from male fitting connection at drain pan inlet due to metal drain pan threads with no Teflon tape added, and hairline crack from seeming to be over tightened. Replaced/sealed fitting and tested drainage several times with no further challenges. Uploaded video.

Technician found compressor over amping rating for 25 rla it was 33 amp. Grinding noise in compressor internally. Technician suspects compressor is failing and shutting down due to internal overload. Due to age technician recommended replacing system. Will require 2 techs if repairs are made due to being in 10 ft ceiling.

2.5 TON GOODMAN PACKAGE HEAT PUMP

Tech found unit #7 had clogged drain line, low on refrigerant and leaking through ceiling. Tech cleared drain and water out of secondary pan, got refrigerant pressures up to spec. Tech found bottom of air handler had condensation dripping onto drain pipe and then dripping onto insulation, tech cleared wet insulation out and spread dry in tech recommended replacing whole section of drywall.
