6 Signs Your Ductless AC Needs Professional Repairs

When your ductless AC isn’t operating properly, it’s time to call a professional. Contact the team at National Heating and Air Conditioning if you’re experiencing issues, including:

  • Strange noises: Clicking, grinding, or thumping sounds are all indications that components of your system need attention, as a ductless system is one of the quietest on the market.
  • Leaking unit: If the mini-split is leaking liquid, the most common culprit is a clogged condensate drain line. Regular maintenance can prevent this issue. 
  • Bad odors: Whether you smell a rotten egg stench or the smell of mildew, unusual scents could be the issue of a leak or improper drainage of condensation.
  • Frozen coils: If your system’s evaporator coil freezes due to dirt and condensation, the ice can warp it enough to require repairs or replacement.
  • Short-cycling: A ductless mini-split that runs constantly or unreliably could mean an issue with a thermostat sensor.
  • Increased energy costs: If your energy bills suddenly spike, your system may not be operating efficiently and could require repairs.
