If you’re reading this because the compressor in your home’s air conditioning system has burnt out, we do have to be honest that this is not great news. The compressor is the heart of an air conditioning system, almost literally because it causes refrigerant to circulate through the rest of the air conditioner and carry out the heat exchange cycle that cools your house. The compressor consumes the most amount of electricity of any component in the AC (and often all the appliances in your house), and when it fails, it may mean the entire AC is finished.
But is this always true? You may have heard that “dead compressor = finished air conditioner.” There is some truth to this. There are also exceptions. The decision to replace the compressor often depends on the age and condition of the old system and whether the existing AC system is still viable. We’ll take a look at four different steps you can take when AC repair in West Chester, PA won’t bring back a compressor.
Diagnosing Compressor Failure in an Air Conditioner
When your air conditioning system isn’t cooling properly, a failed compressor is often the cause. Diagnosing compressor failure involves a thorough inspection of the outdoor unit and indoor evaporator coil, checking for leaks, and testing electrical components to ensure the compressor receives the correct voltage. A professional HVAC technician uses specialized tools to pinpoint issues and recommend whether to repair the compressor or opt for a new air conditioning unit. Prompt diagnosis and repair help maintain energy efficiency and prevent further damage to your system.
It’s important to work with a certified installation team to ensure compliance with local building codes and proper operation of your new AC installation. Other common issues like refrigerant leaks, clogged filters, and faulty thermostats can also affect your existing air conditioner’s performance. Regular maintenance and professional service protect your investment and extend the life of your HVAC system. Whether choosing repairs or a new HVAC system, professional air conditioning installation guarantees reliable cooling and peace of mind.
Replace the compressor
Why not only replace the part that died? Yes, this is feasible. The difficulty is the cost of replacing the compressor, and that’s one of the reasons people often opt to replace the AC instead. Labor costs for compressor replacement can be significant, sometimes making it more economical to invest in a new unit. Compressor failure is most likely to occur in an old air conditioner that’s ready for a replacement anyway.
However, there is a situation where replacing the compressor is the best step: if the compressor is still under warranty. If your AC is under 10 years old and the compressor dies, the warranty will likely cover the cost of putting in a new one.
Replace the condenser unit
I.e. replace the outdoor cabinet. This cabinet contains the compressor, the condenser coil, and the exhaust fan. Replacing the condenser unit may require installing a new copper line set and ensuring the service disconnect and service disconnect box are properly installed or upgraded, including the addition of a new service disconnect box for safety and code compliance. This is less expensive than a full AC replacement, but few people choose this option because it doesn’t come with a new warranty and it can create a mismatch between the indoor and outdoor components that damage system efficiency.
Replace the condenser and the indoor evaporator coil
In other words, replace the whole air conditioner. You don’t need to replace other parts in the HVAC cabinet like the blower or the heater, only the evaporator coil. The new indoor evaporator coil (indoor coil) must be installed properly, connected to the existing sheet metal plenum, and all joints should be sealed to prevent air leaks and ensure efficient operation. This is often the best choice for an older air conditioner because it comes with a brand new warranty and there’s no danger of a system mismatch. If the compressor is no longer under warranty, this is likely the best option to pick. It is essential to create a leak free connection during installation, perform a preliminary leak test, pressure test, and complete the vacuum process to ensure the new system operates efficiently and reliably.
Replace the whole HVAC system
You might look at the failed compressor as an opportunity to make a major overhaul to the HVAC system. This means also replacing the heating system (usually a furnace) and the blower. The new system will include a new furnace heat exchanger, cooling system, and hvac unit, as well as a new refrigeration system. This is, of course, the most expensive choice, but it may make sense if you have a heating system that’s also up in the age range when it’s ready for a replacement. Having the entire HVAC system replaced at one time is more cost-effective than in parts. Proper thermostat operation and the startup commissioning process are essential to ensure the new system functions as intended. If you think your HVAC system is getting ragged and unreliable, this might be the best choice.
The installation will connect the new AC installation to the electrical panel with low voltage wiring and electrical connections, while ensuring proper drainage via a condensate drain line, condensate pump, and floor drain. The team may modify or replace the sheet metal plenum, connect the furnace control, and install the refrigerant line set with the appropriate service valve, suction line, and liquid line, minimizing bends in the two copper lines. Full system replacements often include upgrading to a central AC unit and inspecting or upgrading existing ductwork for optimal performance.
