Many issues can cause an HVAC outdoor unit to stop working, the most common of which are coil and compressor failures.
While both issues are extremely costly to repair, compressor failure is by far the most expensive to repair.
The compressor is located within your outdoor compressor unit. The compressor is the heart of your HVAC system. The total cost of the replacement compressor and the labor involved in installing the compressor will most often exceed the cost of a brand new air conditioning unit. These extreme costs arise because your condensing unit’s compressor takes the longest to repair and is the most expensive HVAC component. Most times, homeowners choose to replace the entire condensing unit instead of only the compressor if it malfunctions. Another circumstance that might force you to replace your condenser is when your condenser is too old. When your condenser is already more than ten years old, it may be time to upgrade to a newer and more efficient unit. Even if repairs can fix a problem, replacing your unit may save you considerable amounts of money. A condenser unit on its last leg tends to break down more often, costing you money on frequent repairs. You may want to replace your condenser when it suffers blockage. A blockage is a major HVAC problem that calls for a replacement. You may also want to replace your condenser when you have leaks. Leaks indicate a major problem in your HVAC system. When you experience leaks in your condenser, you will have to replace the entire component.
