Is It Time for Ductless Repair or Replacement?

Oregon Ductless Heroes


A ductless AC system is a reliable, efficient, and low-maintenance alternative to a traditional central HVAC system. It can last up to 20 years with proper care. Nevertheless, ductless systems aren’t immune to damage and eventually need to be repaired or replaced. Here, we’ll detail when you may need ductless repair or possibly a replacement.

Signs It’s Time for Ductless Repair

Throughout its life, a ductless air conditioner or heater can develop issues. For the most part, these can be fixed quickly if caught early. Call Oregon Ductless if you notice any of the following symptoms:

  • Temperature Inconsistencies: A ductless system should provide consistent heating or cooling. If it doesn’t maintain the desired temperature, output decreases, or the system cycles more frequently, it may need to be repaired.
  • Frozen Evaporator Coil: The coil can freeze up if it becomes dirty, and won’t absorb heat from the air as effectively. It can become warped if the problem persists, in which case the coil must be replaced.
  • Loud Noise: If your ductless AC is making a grinding noise, friction in the motor is increasing. Worn bearings can accelerate wear and cause the motor to overheat and burn out. Squealing can point to a fan motor belt problem, while a hissing sound can mean refrigerant is leaking.
  • Moisture and Water Buildup: If the condensate drain line is clogged with dirt, mold, or algae, water can back up and cause flooding and damage. The drain line must be cleaned out and possibly repaired.
  • Higher Electric Bills: Any issue that restricts airflow can cause a ductless system to work harder, which means it will draw more energy. As a result, your electric bills will spike.
  • The Controls Don’t Respond: If the system doesn’t respond when you press a button, flick a switch, or adjust the thermostat, the reversing valve may be faulty. Or, there may be a problem with an electrical wire or component.
  • Fluid Is Leaking: If there’s a noticeable leak, it may be refrigerant, which is toxic. The system must be repaired. If the coolant drains out, the unit can’t control the temperature and can be severely damaged.
  • Odors from the Ductless System: Foul odors can be caused by mold or bacteria clogging up the evaporator coil, or there could be mildew in a clogged condensate line.

Should I Replace My Ductless Air Conditioner?

You may have scheduled repairs when needed. A maintenance call may never have been missed. Even the most well-kept ductless systems will eventually reach the end of their lifespan. Here are some signs it’s time to start thinking about replacing your ductless air conditioner:

  • It’s Been Repaired More Than Once In the Past Year: An older system may need a repair now and then. But if this happens every few months, chances are more worn parts will need to be fixed soon. More frequent repairs mean spending more, oftentimes more than replacing the system.
  • The Cost of Operating the System Is Higher: As aging parts wear, they decline in performance. The system will run longer to maintain a comfortable temperature. In turn, it uses more energy and your electric bill will go up. If your energy bill is rising for no apparent reason, have a technician evaluate your ductless system to see if it should be replaced.
  • The System Is More Than 15 Years Old: A ductless AC can be used beyond 15 years. However, operating and repair costs may be high. If it is developing multiple problems and you’re starting to spend more to keep it going, it’s time to replace it with a newer, more efficient system you can rely on.
