Signs You Need Repair
If you perform annual maintenance, breakdowns should be rare. Even so, no system is immune to problems. Call our repair team if:
- You spot a fluid leak: Leaks have two potential culprits: water and refrigerant. The latter is toxic and requires urgent repair.
- Your energy bills have risen without explanation: If your mini-split has suddenly started using excess energy, it could be over-cycling to keep up with demand due to backed-up filters or a lack of refrigerant.
- Your system isn’t controlling your climate as well: Efficiency losses could indicate a simple issue like dry refrigerant or a serious problem like a compressor failure.
- Your system is making unusual noises: This can occur due to debris or lubrication issues, but it could also be a sign of loose parts. If your system is squealing, your fan motor belt might need attention.
- Your mini-split starts to smell bad: Your system shouldn’t have a scent. A clogged evaporator coil or condensate line may cause the odor. Your pan might also have a mildew or mold infestation. These issues can affect your health, so treat them as priorities.
- Your outdoor unit has stopped functioning: You might have a blown fuse due to aging or loose wires. Electrical problems are fire hazards, so turn your system off and call for a repair.

FAQs
Is a broken air conditioner an emergency?
Overheating, buzzing sounds, and refrigerant leaks should all be treated as urgent. If you suspect your compressor is producing problems, it’s best not to run your mini-split until it’s professionally assessed.
Why won't my mini-split turn on?
Check your remote before you assume your mini-split isn’t working. You might have flat batteries. If not, your system might have a faulty thermostat, blown fuse, or tripped breaker. Never try to run a system after it’s tripped.
