Cary NC Heating & Air Conditioning Services

Tech found the popping noise was from the back pressure on the supply and return plenums. Tech tested external static pressure and found it at .64 which is slightly high. Pressure drop across coil was .08. Tech verified blower wheel not dirty, coil is clean and filters not clogged. The only repair would be replacing the ductwork. Tech found the furnace is 20 years old and the coil and condenser are both 1989 units. Tech found coil in poor condition, primary and secondary pans both rusted out, drain not insulated, compressor failed megohm test and compressor terminal wire partially melted. Tech recommends replacing unit before ductwork is replaced. Unit is operational at this time. Customer declined replacement appointment. Wants to speak with office

Verified CMA tech findings. System #3 (front dining area) has a hole in the heat exchanger, indoor blower pulleys need to be aligned and have the belt replaced. Gas was shut off due to safety precaution. Compressors are in the caution/bad level, compressors are expected for failure due to low inner insulation value readings. Heat is not operational at this time. System #4 Circuit #2 R22 suction pressure drops, to 26psi, discharge pressure of 147. Suspects low on R22 refrigerant. Need to add 1-2lbs of R22 to text proper operation of the indoor TXV, prior to diagnose a bad Indoor TXV. Leak search level 4 may be needed. Roll out switch is tripped on gas stage #1. Smoked out inducer motor, potential rusted out heat exchanger with holes due to a flame roll out switch triggered. Dual wheel Indoor blower would have to be removed to physically look at heat exchanger. Gas stage #2 is operating properly at this time, capacitors found by CMA tech wound need replacing as well. 2006 model. Only h

Tech returned to complete approved repairs. Tech replaced thermostat for System #1. System is operating correctly at this time. Upon inspection of System #6 tech found weak fan capacitor. Capacitor is rated for 7.5 mfd but tested at 6.60 mfd which is below normal operating range. Tech replaced capacitor and system is operating within specifications at this time. Tech has attached pictures to invoice of repairs.

Tech preformed CMA FULL SERVICE on 5 Gas Package Units. Gas Package Unit #3 is currently down due to pulleys from blower motor and blower shaft being misaligned causing damage to belt. Both Compressors for this unit failed megohm test. Tech also found the inducer motor making a sheering noise indicating fan blades or bearings are damaged. There is also a hole in heat exchanger. Due to multiple challenges tech recommends replacing System. Tech will have office contact customer for further solution. Gas Package Unit #4 is operating at this time but tech found evaporator coil starting to freeze up. Air filters were extremely dirty along with coil, tech did replace air filters and clean coil thoroughly but challenge still exist. Tech recommends Demand tech to further investigate challenge. Tech also found inducer motor #1 for system making sheering noise, indicating damage to fan blades or bearings. Heat exchanger also has severe rust. Unit also has multiple capacitors that are in need of

Tech preformed CMA INSPECTION on 7 Split Systems, 7 Mini Split Systems and 1 Window Unit. Split System #4 ( kitchen) is still down due to compressor being shorted to ground, issue was found during previous CMA Visit. Tech recommends replacing System. Split System #5 ( front nurses station) is operating but has multiple challenges such as leaking evaporator coil, weak fan capacitor, compressor failed megohm test and now compressor is shutting down intermittently due to thermal overload on compressor. Tech recommends replacing System. Split System #1 ( dining room) does operate but thermostat is faulty not allowing system to activate. Tech recommends replacing thermostat. Split System #6 ( front lobby) does operate but found with weak fan capacitor, tech recommends replacing capacitor. Mini Split Systems #2, #5, #6 & #7 do operate with the E.O.S. Tech was unable to locate remotes to control systems to confirm proper operation. Tech recommends purchasing remote controls or installing the

Tech washed and serviced units Will need (2) 10x20 and (2) 12x24 filters dropped off

Tech preformed CMA FULL SERVICE on 2 Gas Package Units. Both units are operating within specifications at this time. Tech did tighten belt on Gas Pack #1. Also during inspection tech found the air filters did not fully cover the evaporator coil. Tech throughly cleaned coil and installed proper size filters. Tech has attached SYSTEM PERFORMANCE REPORTS to invoice along with pictures.

Tech preformed CMA FULL SERVICE on 7 split systems, 7 mini split systems, and 2 window units. Split system #4 is down due to compressor being shorted to ground. Recommend replacing system. Split system #5 is operating at this time, but compressor failed megohm test and evaporator coil has leak. Recommend replacing. Split system #1 is operating but has faulty thermostat, Recommend replacing thermostat. All mini splits systems are missing controls/ remotes, tech was able to activate mini split systems #2,#5,#6, and #7 with E.O. Switch on unit. All four systems are operating at this time. Mini split system #1 and #3 would not activate with E.O. Switch. Mini split #4 has error causing condenser unit not to activate. Recommend demand tech for further diagnosis of mini split systems #1, #3, and #4. Tech also recommends controls or remotes be installed for all mini split systems. Both window units run but do not cool. Recommend replacing. Tech has attached estimates to invoice for any minor r

Tech returned to drop off filters

System ending in 919D has a bad tensioner and belt. Recommend a bx62 rubber belt with the tensioner. The heat does not work, the limit switch is burnt the hot surface ignitor is broken. The gas is not turned on so don’t even know if unit will fire up Heat exchanger exhaust is very rusty and inducer does not move a lot of air through heat exchanger. Heat exchanger has a hole in it. Because the heat needs extensive repairs recommended new system. Curbing unit sits on is also damaged
