Ductless Mini-Split Repair & Maintenance

Mini-split systems need maintenance just like ducted split HVAC systems. When they don't heat or cool properly, the problem is usually one of the following:

• Refrigerant leaks: When the system has a refrigerant leak, it struggles to heat or cool your space. Before long, the coil may even freeze up.
• Dirty components: A dusty, dirty coil or blower can cause mini-split problems. When gunk accumulates on these components, it can inhibit heat transfer and prevent the unit from heating or cooling.
• Dirty filters: When you don't clean your air filter, the lack of airflow can stop the system from heating or cooling properly.
• Bad control board: Mini-splits will have two or three outside control boards and one on the indoor unit. Occasionally, these fail and need to be replaced.
• Poor installation quality: When a mini-split system isn't installed properly, it can fail to heat or cool your space properly. This is a common problem around Atlanta as very few HVAC companies have much experience with mini-splits.

So, what do we look for when you call about a mini-split that isn't working properly? Here's list of steps our technicians follow:

• Cleanliness inspection: We look at the air filter, coils, and blower. When these components aren't clean, the system may not heat or cool. You may also experience airflow issues.
• Check for leaks: We look for refrigerant leaks via visual inspection or, if necessary, with an electronic leak detector.
• Drain line flushing: A clogged drain line can inhibit mini-split performance. When necessary, we clear the line so that water can flow.
• Electrical analysis: We check all wiring and contacts for problems. This inspection will also reveal a bad control board, if that's the problem.
• Installation analysis: Sometimes, a poor installation is the problem. We check that whoever installed your mini-split did so to our rigorous specifications. If they didn't - and some adjustments would help - we can make them for you.
