AC compressors are perhaps the most important part of an AC system. However, issues with a system’s AC compressor can often go undiagnosed or misdiagnosed, which leaves it unresolved.
Air conditioning units can use four different types of compressors. Rotary compressors are common for window AC units and occassionally central AC units. Reciprocating compressors are most common for use in split air conditioners that are lower efficiency. Scroll compressors are the most common. Variable speed, also known as inverter drives are used in high efficiency that are way up on the line. These all range in durability and price.
AC technicians will conduct a diagnostic test to determine whether or not you’ll need an AC compressor replacement. They’ll need to check the terminals and wires to make sure that there’s no electrical damage. If the technician gets a reading that is high when the AC unit is cool, the compressor is in bad shape. If readings from each of the terminals are low, the AC compressor needs replacement.
Before having your AC’s compressor replaced, you should make sure that its warranty is still good. If not, the cost of replacing an AC compressor might end up being even more than the AC itself, in which case it’s better to just have the entire AC replaced.
If the compressor ends up needing replacement, the entire system will need to be shut off. Coolant will need to be removed from your AC due to EPA regulations, and the system should be checked for any leaks afterwards.
AC condensors can be another cause for AC problems. These carry the water along the unit to cool it down further. Due to them carrying water and coolants, there are several potential issues that can arise. Your AC condenser can end up collecting debris and calcium, which can cause issues down the road. Some other possible causes for issues include:
- A bad run capacitor. This part jump-starts the motor each time it starts. The cost of replacement depends on the situation
- A bad relay on the condenser fan. This is what turns the motor on and off. The cost of replacement depends on who’s making the repairs, as well as the model of the condenser fan.
- Motor in the condenser is burnt out. This might slow down or stop the motor altogether. It’s extremely important to make sure that the replacement is the same model as the original. If not, your utility bills will be more costly and the AC systems life span will be shorter.
If you notice any such issues with your air conditioning system, don’t hesitate to give Quality 1 Energy Systems a call!
