Mini-Splint Repair Signs
Warm Air Instead of Cool
If your mini-split is blowing warm air when it should be cooling, it could mean low refrigerant, a clogged filter, or a more serious internal issue.
Weak or Uneven Airflow
Poor airflow may point to dirty filters, blocked vents, or problems with the fan motor.
Leaks or Moisture Around the Unit
Water or refrigerant leaks can damage your system and your home. These should be addressed quickly to avoid bigger repairs.
Unusual Noises
Grinding, buzzing, or rattling sounds often signal loose components, electrical problems, or worn-out parts.
Strange Odors
A musty smell may indicate mold in the system, while burning or chemical odors can point to electrical or refrigerant issues.
Ice Buildup on Coils
Frozen coils are usually caused by restricted airflow or low refrigerant levels and prevent your system from cooling effectively.
Rising Energy Bills
If your energy costs spike without explanation, your mini-split may be overworking due to hidden issues.

Most repairs can be completed in one visit, depending on the issue. Our technicians arrive with the tools and common parts needed to fix things fast. For complex problems, we’ll explain the timeline and keep you updated.
Many systems have manufacturer warranties that cover specific parts. If your unit is still under warranty, we’ll verify what’s covered and help process any claims. Our repairs also come backed by our own workmanship guarantee.
Most mini-split issues can be repaired, especially if the system is under 10–15 years old. Our technicians will assess the condition of your unit and let you know if a repair is cost-effective or if a replacement would be the better long-term option. We always offer honest recommendations based on performance, efficiency, and total repair costs.
