If your ductless mini-split system isn’t working like it used to, Arctic Air is ready to help. We provide expert ductless mini-split repair services for homeowners across New Jersey, backed by real experience and a team that shows up prepared to fix it right.
Ductless systems are efficient and reliable, but no HVAC equipment lasts forever without issues. If your unit is blowing warm air in cooling mode, refusing to turn on, or making strange noises, our technicians know what to look for, and how to get your system running again fast.
Signs of Issues
A struggling mini split usually gives you some warning before it completely breaks down. Spotting these signs early can help you avoid bigger repairs later.
Watch for:
- The system won’t turn on or respond to the remote
- The unit is blowing warm air when it should be cooling
- Odd buzzing, clicking, or grinding noises
- Weak airflow or uneven room temperatures
- Water leaking from the indoor unit
- Flashing error lights or trouble codes on the display
- Musty or burnt smells during operation
- The system turns on and off more than usual
- Your energy bill has gone up without reason
If you notice any of these issues, don’t wait. A simple repair now can prevent bigger problems later and keep your system running efficiently.
Troubleshooting Guide
Some issues have simple fixes. Others need a trained technician. Here are a few common problems and what might be causing them:
- System is blowing cold air in heating mode
This might be due to an incorrect mode setting, a sensor error, or an issue with the reversing valve.
- System is blowing hot air in cooling mode
A low refrigerant level, clogged filter, or dirty outdoor coil could be to blame.
- System won’t turn on at all
Check the breaker, remote batteries, and power connection. If that’s not it, it could be a board or capacitor issue.
- Airflow feels weak or inconsistent
Dirty filters, blocked air paths, or a faulty fan motor are common causes.
- Water is leaking indoors
A clogged condensate drain, or loose drain line may be the problem.
If you’ve gone through the basics and the issue still isn’t clear, give Arctic Air a call. We’ll send someone out to take a look and get things sorted.
Repair vs. Replacement
Not every issue means you need a new system, and we don’t believe in pushing replacements if a repair will do the job. That said, in some cases, a replacement makes more sense financially and functionally.
You might want to consider replacing your ductless system if:
- It’s over 10 to 12 years old
- Repairs are becoming frequent or expensive
- The system uses outdated refrigerant
- Energy usage keeps rising despite regular service
- You’re not getting the comfort you used to
- You’re planning to expand or add more zones
We’ll walk you through the pros and cons of repair versus replacement, based on your system and your comfort goals. If a replacement is the better choice, we also provide expert ductless installation and replacement services across New Jersey.
