Or see COMPRESSOR MOTOR REPLACEMENT FAQs - questions & answers about A/C or heat pump compressor motor replacement requirements posted originally at this page The air conditioning system, with its new compressor installed, will be re-started and checked for proper operationĬontinue reading at CAPACITORS for HARD STARTING MOTORS or select a topic from the closely-related articles below, or see the complete ARTICLE INDEX.Overcharging and under-charging refrigerants will lead to improper system operation. Must be measured precisely (including temperature, pressure, and volume during charging) for the system to work properly. Use a hermetically sealed compressor motor and there is no separate receiver to hold a large refrigerant charge, so the charge Residential air conditioner systems, unlike commercial units, Refrigerant is added to the system at the proper charge amount.Any water or moisture in the system is also removed and as we noted above, during re-connection of the refrigerant piping the technician may install a compressor burn-out filter-drier in the system to remove any trace moisture that remains behind after reassembly.Air contamination, if allowed to mix with the new refrigerant would change its operating characteristics and A vacuum is pulled on the entire system both to evacuate all air from the refrigerant lines and compressor and to checkįor leaks in the system.This special HVAC compressor burnout dryer / filter may be installed on the refrigerant line(s) to provide extra debris and moisture and oil filtering capacity to protect the new equipment from debris clogging.Ĭapillary tubes and TEVs as well as coils and compressors are vulnerable to damage or clogging from debris, stray oil, or water in the refrigerant piping system. A compressor motor burn-out filter is installed, possibly two of them on both the low and high side refrigerant lines at the compressor/condenser unit.Or other controls may need to be cut out and replaced if the refrigerant is being changed too. Outside), and its refrigerant lines are connected (usually silver soldering) to the existing refrigerant lines. The new compressor is installed in place in the compressor/condenser unit (usually all of this equipment is located.The refrigerant lines are cut and the old compressor is removed.Not all components need replacement, however ducts and blower assemblies, Thermal-expansion valves, coils, or other components. To use a new, approved refrigerant and other changes may be needed to the system to accommodate this change, such as changes in If the air conditioner system used a now-obsolete refrigerant such as R11 or R22, a the new compressor will be one designed.Modern procedures require that the refrigerant be captured rather than released to theĮnvironment in order to reduce environmental pollutants Remove all refrigerant from the system.Shut down the air conditioning system, including turning off electrical power.Identify the compressor model and capacity so that a proper replacement can be obtained.HVAC NOISE-3 HISS HOWL HUFF HUM - where humming compressor noises are discussed HARD STARTING COMPRESSOR MOTORS - sometimes a start capacitor or relay replacement are all that's needed Note that a short-cycling or humming compressor may be due to other system problems - it's not always the case that the motor is actually seized.īURNED-OUT COMPRESSOR - how to determine that the compresor motor is burned out or seized Confirm that the compressor has failed and needs replacement.
