AC coils, also known as evaporator coils (inside the unit) and condenser coils (outside the unit), are essential for the heat exchange process that cools your home. They play a vital role in the AC cycle, working in conjunction with the refrigerant, compressor, and other components to provide the cool air you crave during those hot summer months. Understanding the function of these coils and how to troubleshoot common problems is key to keeping your AC running smoothly and efficiently.

Before we delve into the repair process, let’s take a closer look at how AC coils work. Phoenix Air Conditioning Repair Fix My Ac Weekend Air Conditioner Repair Air Conditioner Repair Man

• Evaporator Coil (Inside Unit): This coil is responsible for absorbing heat from the air inside your home. Warm air passes over the cold evaporator coil, causing the refrigerant inside the coil to absorb the heat and change from a liquid to a gas. This process cools the air, which is then circulated back into your home via the ductwork.
• Condenser Coil (Outside Unit): This coil releases the heat absorbed by the refrigerant. The hot, gaseous refrigerant travels to the condenser coil, where it releases the heat to the outside air and condenses back into a liquid. This process is facilitated by the condenser fan, which helps to dissipate the heat.

DIY Troubleshooting and Inspection Commercial Air Conditioning Repair Near Me Hvac Service Companies Near Me Heating And Air Conditioning Service Near Me Heating And Ac Companies Near Me

Before calling a professional, you can perform some basic troubleshooting steps to identify the problem. Commercial Aircon Servicing Commercial Hvac Service Near Me Heating & Air Conditioning Service Near Me Ac Repair Nearby

1. Check the Air Filter: A dirty air filter restricts airflow, which can cause the evaporator coil to freeze. Replace the filter regularly (every 1-3 months) or clean a reusable filter.
2. Inspect the Vents: Ensure that all vents are open and unobstructed. Close any vents in unused rooms to direct airflow to the areas you use most.
3. Examine the Evaporator Coil: If you have access, visually inspect the evaporator coil for ice buildup. If there is ice, turn off the AC unit and let it thaw completely. Check the air filter and vents. If the problem persists, it’s likely a more serious issue.
4. Inspect the Condenser Coil:
   • Turn off the power to the AC unit.
   • Remove any debris (leaves, twigs, grass clippings) from around the condenser unit.
   • Use a garden hose with a gentle spray to clean the condenser coil. Be careful not to bend the fins.
   • Check for physical damage or signs of leaks.
5. Listen for Unusual Noises: Hissing or bubbling sounds may indicate a refrigerant leak. Grinding or squealing noises could point to a failing compressor or fan motor.
6. Check Refrigerant Lines: Look for any oily residue on the refrigerant lines, which can indicate a leak.
