According to the U.S. Department of Energy, heating and cooling account for about 48% of the energy use in a typical U.S. home. That makes your air conditioning system one of the most important-and expensive-appliances you own.
Understanding the key air conditioner parts isn’t just for repair pros. For folks in Franklin, TN, knowing your cooling system parts helps you spot issues early, save money, and stay cool without stress.
Below is a breakdown of the air conditioning essentials that keep your home frosty. Keep reading to learn more.
The Compressor
Think of the compressor as the heart of your AC. Located outside, it pumps refrigerant through the system, absorbing heat from inside your home and releasing it outside.
If your AC struggles to cool, the compressor may be calling for help. Keep its area clear of leaves or debris.
The Condenser Coil
Paired with the compressor, the condenser coil (also outdoors) turns hot refrigerant gas back into liquid by releasing heat. But if it’s clogged with dirt, you have to endure sweaty afternoons.
A dirty condenser coil can block this process, making your system work harder and use more energy. EPA recommends cleaning your condenser coil at least once a year to keep your system running smoothly.
The Evaporator Coil
Located inside your home, the evaporator coil is responsible for absorbing heat from the indoor air. The refrigerant enters the evaporator coil in a low-pressure gas form and evaporates, pulling heat from the air. This process helps cool your indoor space.
Dirty evaporator coils can reduce your system’s efficiency. Regular maintenance is crucial to keeping AC unit components in top shape.
The Expansion Valve
The expansion valve acts as a bridge between the condenser and evaporator coils. It regulates the flow of refrigerant, dropping its pressure before it enters the evaporator coil. This pressure drop ensures effective cooling.
If the expansion valve fails, your system can’t cool properly. You may notice warm air blowing from your vents. This is one of the HVAC system parts that often gets overlooked, but it’s important for cooling.
The Air Handler
The air handler, often paired with a blower fan, circulates cool air throughout your home. It pushes air over the evaporator coil and into your ductwork. A well-maintained air handler ensures even cooling and helps filter out dust and allergens, improving your indoor air quality.
Your Air Conditioner Parts Maintenance Cheat Sheet
Once you know these important AC parts, you need to stop problems before they start. Here are some quick tips to maintain your AC:
- Regularly change the air filter to ensure good airflow and quality
- Keep the area around your outdoor unit clear of debris
- Check for leaks or unusual noises regularly
- Schedule annual HVAC maintenance with professionals for thorough inspections
Spotting a failing AC early can save you money. Also, understanding your air conditioning essentials helps you talk confidently with HVAC pros.
