If you have a Mitsubishi mini split system air conditioner in your home, you’ll need to hire a reputable HVAC company for regular maintenance to ensure it continues running properly throughout the year. Over time, any appliance collects dust, dirt, mold and grime. Long-term exposure to these pesky particles can affect the performance of your Mitsubishi split system. System components can also wear down over time and need to be inspected.
To help this air conditioner perform better and last longer, hire Grove Heating & Cooling for mini split maintenance. Although you may be tempted to clean and tune up your Mitsubishi mini split system on your own, these are complex systems, and it’s best to leave system maintenance to a trusted HVAC technician.
What’s Included in Ductless Mini Split Maintenance?
The NATE-certified technicians at Grove Heating & Cooling will inspect your entire ductless system from top to bottom. Our mini split tune up checklist includes:
Cleaning
We deep clean all of the coils to remove any debris to prevent mold and mildew from forming. Coil cleaning is essential for optimal efficiency.
Electrical Contacts
Poor electrical wiring can lead to ice forming on the outdoor coil during the winter months and on the indoor coil during the spring and summer. We check all wires and electrical components for signs of wear.
Refrigerant Levels
We inspect the refrigerant lines for signs of leakage.
Airflow Issues
A dirty or blocked air filter inhibits airflow from the indoor and outdoor heat-exchange coils. During our tune up, we remove and clean the air filter inside the indoor air-handling unit. We also inspect the outdoor cabinet for any airflow obstructions.
Drainage
To prevent damage and water leaks, we flush the drain lines to prevent mold and algae.
Compression
Many of the components in a ductless mini split system are complicated and should only be checked by a qualified HVAC technician. We inspect and test the following components: electronic expansion valves (EEV), sensors and digital inverter-driven compressors. All of these play a role in preparing, regulating and monitoring super-heating of the refrigerant.
DIY Tips for Your Mini Split System
Cleaning, maintenance and repairs should only be performed by an HVAC technician. However, there are a few simple DIY tips homeowners can perform to help ensure their system runs efficient.
A dirty or blocked air filter prevents proper heat exchange, which can significantly increase your energy bills. We recommend changing the air filter once per month. You can also inspect the outdoor unit periodically to clear away any obstructions, including leaves, twigs, snow or ice.
Signs Your Ductless System Needs Service
If you’re experiencing issues with your ductless mini split system, call Grove Heating & Cooling for reliable service. We’ll inspect the system and get to the root of the problem and make a repair. Some of the common reasons ductless systems need service include:
High Electric Bills
Unusually high electric bills can signal that something is awry with the system. Mini split systems are built to last about 15 years, so higher energy bills could indicate the system is losing efficiency and may need replaced. Other issues related to high energy bills are clogged air filters or failing parts.
Unusual Noises
A grinding noise coming from the indoor unit could mean the oil bearings have worn down. This needs to be inspected to prevent the air handler motor from overheating.
Ice Forming on the Coils
Ice on the outdoor cooling coils can reduce airflow. A broken fan, refrigerant leak or clogged air filter could be the culprit.
Decrease in Cooling Power
A decrease in the system’s cooling power over time could mean there’s a refrigerant leak.
