In this blog post, we will go over the most common mini split AC repairs and what you need to know to complete them. We will also provide some helpful tips on how to prevent these repairs from happening in the first place. Let’s take a look!

What Is a Mini Split AC System

Part of understanding the repairs needed for a mini split system also means knowing more about the unit, its parts, and how it works. A Mini Split AC system is a type of air conditioning system that does not require ductwork. Mini Split AC systems have two main parts: a single outdoor compressor/condenser and an indoor air-handling unit are used. The power cable, refrigerant tubes, suction tubes, and drain hose are all contained in a conduit that links the outdoor and indoor units.

How Does a Mini Split AC System Work

The outdoor compressor/condenser unit of a Mini-Split AC system pumps refrigerant to the indoor air-handling unit. The indoor air-handling unit blows air across a heat exchanger, cooling the air and causing the refrigerant to evaporate. The now cold and vaporized refrigerant is then sent back to the outdoor unit where it is condensed and pumped back into the indoor unit.

Common Problems With Mini Split AC Systems and How to Troubleshoot Them

There are a few common issues that can happen to a mini split AC unit. The most common problems with Mini Split AC systems include:

  • The outdoor unit not running
  • The outdoor unit not getting power
  • Refrigerant leaks
  • The indoor unit not blowing air
  • The air is not being cooled by the indoor unit
  • There is water leaking from the indoor or outdoor unit

To troubleshoot problems with your mini split AC system, you should have it serviced by a qualified technician at least once a year. You should also keep the area around your outdoor unit clear of debris and make sure that the indoor unit is not blocked by furniture or curtains.

If you do experience a problem with your mini split AC system, it is best to call a qualified technician for repairs. Attempting to repair the system yourself could void your warranty and cause further damage to the system.

Signs That You Need a Mini Split AC Repair

What are the signs that you need to get your mini split AC repaired? Let’s go over five signs that it’s time to contact a professional HVAC specialist.

1. The Air Conditioner Is Not Cooling as Efficiently as It Used To

One of the most common signs that you need Mini Split AC repairs is when the unit is not producing as much cool air as it used to. If you notice that your home or office is not as cool as it used to be, then it’s time to have an HVAC technician take a look at your unit.

2. The Air Conditioner Is Making Strange Noises

If you start to hear strange noises coming from your mini split AC, then it’s time for repairs. Common sounds that indicate a problem include clicking, grinding, or hissing.

3. Mini Split AC Leaking Water

Another sign that you need to get your mini split AC repaired is if it starts to leak water. This is usually a sign of a refrigerant leak and it can be very damaging to your unit if left unrepaired. However, this could be water as well, depending on the mode you were using.

4. The Air Conditioner Is Cycling on and off Frequently

If you notice that your air conditioner is turning on and off more than usual, it could be a sign of several different problems. It could be something as simple or it could be something more serious like an electrical issue. Either way, it’s best to have a professional take a look.

5. The Air Conditioner Is Blowing Hot Air

This is probably the most obvious sign that you need mini-split AC repairs. If your unit is blowing hot air, then it’s not doing its job! This problem could be caused by several different things, so it’s best to have a technician take a look.

If you’re experiencing any of the above issues, then it’s time to call in an HVAC professional for mini split AC repairs. Ignoring the signs listed above can lead to bigger problems down the road, such as complete system failure. These are all repairs that are not typically DIY and require a pro to take care of it.

Why You Need a Professional for Mini Split AC repairs

Attempting to repair your mini split AC unit on your own can be extremely dangerous. AC units contain harmful chemicals and high voltage electrical components that can be deadly if you don’t know what you’re doing.

In addition, repairing your AC unit on your own voids any warranty that may still be active. So, not only are you risking hurting yourself or the unit, but you’re also throwing away any chance of getting free repairs from the manufacturer.

Mini Split AC Repair – What Needs to Be Done and Who Should Do It

Most Mini Split AC repairs are best left to the professionals. They have the tools, training, and experience necessary to properly repair your AC unit. However, there are a few things that you can do to troubleshoot and fix minor issues with your mini split AC unit.

Change or Clean the Air Filter

If you notice that your mini split AC unit is not cooling as well as it used to, the first thing you should check is the air filter. A clogged air filter will restrict airflow and cause the unit to work harder to cool the space. Replacing a dirty air filter is a quick and easy fix that anyone can do.

Check the Circuit Breaker

Another simple fix is if your AC unit isn’t turning on. Go out and check your circuit breaker. It could have flipped the switch and you can easily turn it back on.

Check the Thermostat

Last, if you’re not getting cool enough air, you can check the thermostat on the unit. If you haven’t checked on it in a long time, it could lose its settings. You can also check the batteries and ensure that everything is running as it should.

While most mini split AC repairs are best left to professionals, there are a few things that you can do to troubleshoot and fix minor issues on your own. By checking the air filter and making sure the breaker is on and that your thermostat is working properly, you can often resolve common cooling issues.

However, if your AC unit is still not performing properly after these checks, it is time to call in an HVAC professional. A trained technician will be able to quickly diagnose and repair any issues that your AC unit may have.
