With the warm weather officially settled in most parts of the United States, some homeowners since the fall since the first start air conditioning to find them no longer work. It may be difficult to decide to replace the condensing unit rather than repair the condensing unit, and some contractors have developed guidelines to help the owner make such a decision.
Many things may cause the outdoor condensing unit to stop working, the most common of which is the compressor and coil failure.
Compressor failure is by far the most expensive parts to fix. The compressor is the engine or heart of the system. The actual cost of replacing the compressor and the installer usually exceeds the cost of the new a / c unit.
Compressors and coils usually change in the condenser, and fan motors often cause problems. Compressors need the longest time to repair, and the most expensive part. In most cases, when the compressor is not good, the customer chooses to replace the entire unit.
Typically, the reason is that in older units the compressor starts a large number of electrical amperage at the start-up cycle and, over time, will cause the capacitor to fail.
The failure we see is generally due to poor maintenance, and the condenser's condenser seems to be an important cause of the failure. The fault may be from a catastrophic compressor to a failed operating capacitor, and the capacitor is a common repair. Compressor replacement is by far the most expensive, especially if the unit is an R-22 system.
When determining whether a unit is on its last legs, most contractors agreed that run time and operating conditions are the most important factors to consider.
For elderly units that experience compressor failure, Merritt says maintenance units are usually not worth it, especially because there is usually one reason that will deteriorate, so not only do you have a very expensive compressor, but you have another problem, You can not diagnose until you replace the compressor.
