Common AC Unit Parts
Keeping your HAV system in an excellent condition sometimes means that you have to replace old parts that have failed or are on their way to failure. As long as you keep up with your annual maintenance, a reputable AC technician will be able to catch those failing parts before they cause more significant issues. One of the most common parts of AC unit are capacitors and contactors.
Capacitors and Contactors
The capacitor is a vital piece of your outside AC unit parts because it s what provides the electricity to turn on the unit and keep it running. The contactor controls the energy flow to the unit’s vital components. These parts are the most likely to break in your system, but they are also the most important. Thankfully, these pieces are relatively inexpensive to replace.
Over time, the coils in your unit become dirty with debris, but as long as you clean them regularly, they should last you a long time. If you don’t keep them well maintained, they can become corroded, which will lead to them needing to be replaced. These coils also lead to a loss of refrigerant.
You should check and regularly replace your air filters once every three to six months. Although your air filter is slightly different than the actual components of an A/C, it is just as equally as important. If you don’t change this filter regularly, it can become clogged, restricting the airflow into your home.
When you live in a state like Texas, your HVAC system is almost always going to be running. If that is the case for you, then you may want to watch your blower motor because it can burn out due to continual use. During your yearly maintenance, your technician will notice if your motor is wearing out, and if needed, they can replace it for you.
The compressor is the most expensive central AC unit parts to replace, and it is the most essential part of the unit. If this part fails, it can cause the entire unit to break down.
If you have a unit older than eight years old, it may be smarter, if not cheaper, to buy a new unit instead of replacing the compressor. Replacing your compressor will cost you around $400 for the AC unit part and approximately $1,000 for labor.
