Homeowner’s Guide to Mini Split Systems

If your ductless mini-split is acting up, you may be able to identify the issue without hiring an expert. While we highly advise against attempting to conduct repairs yourself, there are sometimes simple maintenance tasks that could remedy the problem.

Indoor Comfort Team provides service to the entire St. Louis area – including Belleville, IL. Residents across Belleville have relied upon our team of qualified HVAC technicians for a variety of home comfort services. We want to support our customers with the knowledge needed for their heating and cooling systems to work properly and efficiently for as long as they can run.

If you have a ductless mini-split system – whether you live in Belleville or anywhere – here are some basic maintenance information and troubleshooting steps to help you keep your unit operating just as it should be.

Clean the Air Filter

If your ductless system isn’t providing enough heat in the winter, it might be because of a clogged air filter. The filter should be plainly visible when you lift the lid of your indoor wall unit. Clean it with water and make sure it’s fully dry before replacing it. If you need professional mini split maintenance service, call Indoor Comfort Team at 314-230-9542 or request service by sending us a message online.

Listen for Hissing Sounds

This could mean your ductless mini-split has a leak. HVAC systems with refrigerant leakage will occasionally generate hissing sounds. These hissing noises might be faint if the leak is minimal or loud if the leakage has gotten out of hand. If you detect hissing noises emanating from your unit, contact a professional repair mini-split technician after you’ve turned it off. Call Indoor Comfort Team for service in Belleville or anywhere in the greater St. Louis area at 314-230-9542.

Reposition Your Remote Control

A remote that includes a thermometer controls most ductless AC units. Since electrical components can be sensitive, you don’t want your remote to experience major fluctuations in temperature. Make sure your remote isn’t in the direct line of heat from your ductless system so it doesn’t overheat.

Check the Circuit Breaker

Sometimes the problem with your ductless mini split is due to an electrical issue. Electrical problems with your HVAC system are a serious subject, and unless you’re a trained electrician, you should never tamper with live wires. Having said that, it isn’t risky to just open your circuit breaker box and inspect the switches within. If the circuit that powers your ductless system is off, turn it back on to test if it returns power.
