Rocky Mount NC Heating & Air Conditioning Services

Upon arrival tech found system has no airflow tech inspected system and found system had iced up. Tech cleared up ice and found pressure were good, tech found no filter in return customer stated he had just pulled it out because it was very bad. System was freezing up to dirty filter and is now back up and cooling with a 20 delta t.

Tech got pictures of ceiling around downstairs return. Cased evap coil is below down flow gas furnace in upstairs closet. Went upstairs and confirmed drain is clear. There is no float switch. Poured multiple bottles of water into drain pan and saw it flow out. Suspects water spots around return are not from drain, but from frost melt from freezing coil. Called for cooling and found system very low on R22. System only holds 4.6 lbs of R22. Due to age and refrigerant leak, tech recommends system replacement. Customer decided to add R22 for the time being. Tech let her know that it would be a temporary solution. Customer approved adding R22. System is back cooling now. Did not see any dripping. No housecall per customer satisfaction. Collected for refrigerant.

Upon arrival tech found kitchen system running, thermostat indoor temp reading 77 set to 70. Tech monitored R22 pressures and found them to be low. Found a leak at evaporator coil, informed administrator that a field supervisor will have to verify and give options on repair or replacement. Customer agreed and also requested to charge system up until quotes are given. Tech added three pounds of R22. System is cooling with an 18 degree delta t. Billing out repairs.

Tech checked out the wiring to the RTUs(roof top units) and found all the units jumped from Y1(stage 1) and y2(second stage). Systems are cooling properly, however, having both stages operating the whole time, it does not allow the systems to dehumidify and not allow the re-heat coil to engage to dehumidify on 1st stage. Costumer has experienced this challenge prior to us servicing it. Tech wired all 2 stage units and thermostats to where they have a dedicated Y2 wire from the thermostat to the unit for better humidity control and cooling staging, re-heat coils are functional, no stuck reversing valves.. Tech received approval from Emily for todays repairs. A follow up visit may be needed to monitor the humidity levels.

Best solution is to replace both systems. Customer is going through a debt reduction process right now and can’t do any financing

Tech washed and serviced both units and found downstairs unit to have have extreme evap coil rust and compressor testing in the red along with rust starting to take over heat exchanger tech tech also found upstairs unit have have bad evap rust as well and compressor testing in the caution tech called out field supervisor for both systems field supervisor will arrive around 1 today. Tech did recommend having ez trap installed for upstairs unit customer wants to wait and see how everything goes with field supervisor first. Downstairs unit was cooling with a delta t of 15 and upstairs had a delta t of 11

Have Mrs Wiggins pricing on replacing gas furnace and ac. Has to talk to husband. Unit is not cooling properly at this time it seems

Tech found system compressors was not operating. Tech reset system circuit 1 started up no issues circuit 2 started up and shut down within 2 mins of operating.

Tech will speak with office of findings.

Tech found condenser had contactor pulled in but no power to it tech went to main panel and found breaker was in on position tech flipped breaker off and on and system started up tech checked amp draws are within spec’s system was making noise from metal on metal rubbing tech put padding in between the door and cabinet noise quite down. System is cooling tech believes breaker in main panel did not engage properly p. Tech turned breaker on and off each time system started up.

Upon arrival tech found system not running due to failed disconnect. One line voltage wire was melted due to a loose connection. Terminal in disconnect was also melted.

Costumer stated that another individual already diagnosed a bad compressor and will be repairing it. No diagnostics performed.

Observed noise with compressor operating. Refrigerant pressures seem as expected. Voltage, compressor amperage, and capacitor test okay. Verified air flow and clean air filter. Temperature difference at condenser 53 supply 62 return. Customer has thermostat set at 58 degrees. Suspect noise is due to low outdoor temperature and very low indoor setting. Recommend follow up visit on higher temperature day to perform full system operation check.

Tech found the thermostat in the kitchen not cooling due to the thermostat being set to 90 on cooling, set temperature to 70 and system operated in cooling. System condenser is extremely clogged.
