Signs You Need AC Repair

Seek the help of a professional HVAC technician If you experience the following problems and looking for a Mini Split Air Conditioner Repair in Monroe County Michigan.

1. Water Leakage

Your mini-split AC uses refrigerant to circulate cold air, which can cause condensation. However, water or moisture should not accumulate and leak into your home. A water leak around or under your air conditioner means that your air conditioner is not working properly. In addition to water, your air conditioner can also leak refrigerant. Refrigerants are poisonous and dangerous to your health.

If you notice a pool of water under your air conditioner or a moisture build-up with a strange colour, it’s time to call an HVAC professional for repair. In the meantime, do the following:

  • Turn off the AC unit to stop the water flow and prevent further damage.
  • Turn off appliances and electrical equipment to avoid electric shock.
  • Remove the water and wipe the floor and affected areas immediately.

2. Unusual Alternating Noise

The low-noise ductless mini-split AC operates with a noise level of around 40 decibels – this is comparable to the sound of a table fan. If you hear unusual noises or noises, have an HVAC professional inspect your AC unit, such as:


A High-pitched Scream or Hiss

A build-up of high pressure in your AC’s compressor creates a high-pitched hissing sound that can destroy the unit. If the AC unit does not turn off automatically, turn it off immediately.

Metal Screeching

A metal-on-metal screeching sound can come from loose or broken fan motor bearings in the outdoor unit. If this is the case, your AC unit may require a fan replacement.

Whistling Sound from the Indoor Unit


This could indicate a problem with the fan belt. At first, this sound comes and goes, leading many to ignore the problem. However, if the fan belt has a problem, it will eventually break and cause your AC unit to shut down.

3. Odor from AC

An unpleasant or unusual smell coming from your AC unit when the air is blowing can indicate a variety of problems. If you notice a burning smell, this may indicate an electrical wiring problem or a problem with the unit’s insulation. If you notice a musty smell coming from your air conditioning unit, you may have a mould contamination in your home. Report this problem to your HVAC technician right away, as the contention in the air in the room can harm you and your family. Duct cleaning can remove mould and odours that accumulate in the ducts.
