Ductless mini split heating and cooling systems are known for their reliability, but even the best HVAC equipment can encounter occasional problems. Beyond issues that reduce performance, there are other common malfunctions you may encounter over the lifetime of your ductless mini split system. Robinson Heating and Air Conditioning, Inc. tackles them all, including:

Water Leaks

A clogged condensate drain line can cause water to back up and leak from your indoor unit. Our technicians effectively clear the clog and ensure proper drainage to keep your ductless mini split working efficiently and prevent water damage.

Unusual Noises

Strange noises like grinding, banging, or screeching from an indoor or outdoor unit can indicate loose components, failing fan motors, or low refrigerant levels. We identify the source of the noise and implement the necessary repairs to eliminate any noise issues.

Uneven Airflow

Weak or uneven warm or cooled air throughout your home could be caused by a clogged air filter, blocked vents, or a malfunctioning blower wheel. Our team thoroughly cleans your system, repairs defective fans, and ensures optimal airflow.

Loss of Functionality

Sometimes, your system simply won’t turn on or respond to commands. This could be due to a power issue, a faulty thermostat, bad electrical components, or an internal control board problem. Our technicians troubleshoot the cause and get your system back up and running.

We know HVAC system repairs can feel overwhelming, especially when your comfort is on the line. We make the process simple, transparent, and stress-free from start to finish. That’s the way we’ve done it for decades—and it’s why West Chester homeowners trust Robinson Heating and Air Conditioning, Inc. when comfort matters most.

While repairs can often extend the life of your system, there are situations where replacing it might be the more cost-effective option. Most ductless mini splits have a lifespan of 10-15 years. If your system is approaching this age and experiencing frequent breakdowns, a newer, more efficient model might be a wise investment.

Are you encountering constant repair needs? The cost of repeated repairs can quickly surpass the investment in a new system, which would come with a fresh warranty and improved efficiency.

At Robinson Heating and Air Conditioning, Inc., we understand the complexities of making this decision. Our experienced technicians provide a thorough inspection of your existing system and discuss your options with transparency. We offer ductless mini split installation services for a seamless transition to a new system if that’s the best course of action.

Lukewarm air during a heatwave is a homeowner’s nightmare. Here’s what might be hindering your ductless mini split’s cooling capacity:

• Incorrect Temperature Setting: Double-check your thermostat settings. Ensure it’s set to “cool” mode and the desired cool temperature.
• Blocked Airflow: Blocked air intake or outlet vents restrict proper air circulation. Check for furniture, curtains, or debris obstructing airflow.
• Dirty Indoor Unit: Dust and grime buildup on the indoor unit’s coil reduces its ability to absorb heat. Regular cleaning by a professional is crucial.
• Frozen Coils: Icy buildup on the indoor unit’s evaporator coil can impede airflow. This typically occurs due to dirty air filters, refrigerant leaks, or incorrect system settings. Turn the system off and allow the ice to melt naturally. If freezing persists, contact a professional.
• Sensor Issues: Faulty temperature sensors might send inaccurate readings to the unit, preventing it from achieving the desired coolness. A technician can evaluate and replace faulty sensors if necessary.
• Improper System Sizing: An undersized mini split might struggle to cool your entire space efficiently. Consult an HVAC professional to assess your needs, as a new ductless mini split installation may be necessary to eliminate this problem throughout the entire system.

Don’t sweat through another day without the proper cooling you deserve. Robinson Heating and Air Conditioning, Inc.’s technicians get to the bottom of your cooling issues and perform the right repairs to restore your comfort.

When your ductless mini split isn’t producing efficient heating, it can leave you and your family uncomfortable during Ohio’s coldest days. While these systems are known for their reliability, a few common issues can keep them from doing their job.

If your mini split is blowing cold air or not responding at all, here are some possible reasons:

• Incorrect Settings: The unit may be set to cooling or dry mode instead of heat. Double-check your remote settings and temperature.
• Dirty Air Filters: Clogged filters can restrict airflow and prevent the system from heating properly.
• Refrigerant Leak: Low refrigerant levels can reduce heating performance or stop it entirely.
• Frozen Outdoor Unit: Ice buildup can prevent your system from operating in heat mode, especially in freezing temperatures.
• Faulty Thermostat Sensor: If the system can’t detect room temperature accurately, it may not heat the space effectively.
• Blocked or Dirty Coils: Dust, debris, or grime on the coils can interfere with heat transfer.
• Malfunctioning Reversing Valve: This part controls whether your system is in cooling or heating mode. If it fails, your system may be stuck in cooling.
• Electrical or Control Board Issues: If your mini split isn’t turning on at all, the problem could lie in the internal wiring or electronics.

Some of these issues are simple fixes, while others require professional service. If you’re unsure what’s causing the problem, the best next step is to schedule ductless mini split repair service in West Chester, OH, with a trained technician from Robinson Heating and Air Conditioning, Inc.
