The Most Commonly Repaired HVAC Parts: Part Two

This week we’ll look at some more commonly repaired parts of your Delaware HVAC system. Remember that your HVAC unit covers both heating and cooling, with some components designed exclusively for one function. That’s why it’s important to have routine maintenance check-ups on your unit before summer and winter: if a component specific to one function or the other has broken out-of-season, you will want to repair it before the extreme temperatures hit.

Delaware HVAC Components

  • Capacitors – There are actually two capacitors in your system; a run capacitor and a start capacitor. As you might have guessed from their names, the start capacitor helps your unit have the necessary torque to start up the motor. The run capacitor helps the motor maintain a consistent speed while operating. If either capacitor fails, it will need to be replaced for your Delaware HVAC system to work properly.
  • Condenser coil – This is located in the outside compressor unit, and as such is exposed to the elements. This can cause the coil to become coated in dirt and grime. Without regular cleaning, the built-up dirt can cause the coil to fail, preventing your unit from operating.
  • Compressor – The compressor is the heart of your HVAC unit. Out-of-balance refrigerant is the most common cause of compressor failure: too little refrigerant will cause the compressor to overheat and eventually seize. Too much refrigerant will flood the compressor and cause liquid slugging. Maintaining proper refrigerant levels will help prevent compressor breakdowns.
  • Refrigerant – Refrigerant is key to the function of the AC portion of your HVAC system. Vibration of the unit as it operates can cause refrigerant leaks, leading to system malfunction. While leaks in the evaporator and condenser coils cannot be repaired, leaks in other locations (such as the lines – the most common place) can be repaired by your Delaware HVAC repair technician. They will have to drain the remaining refrigerant to make the repair, then recharge your system to proper refrigerant levels.
  • Drain lines – During normal air conditioning use, condensation will develop on the evaporator coil. This water is gathered into a drain pan and then exits your home through the drain line. This line can often become clogged with dirt and algae, causing the drain pan to fill and up and cause water leaks around your unit and water damage to your home.
