If you have a ductless HVAC system in your home, you may have noticed that it seems to be running all the time. There are a few reasons why this might be the case, and fortunately, there are also a few things you can do to fix the problem. Keep reading to learn how.
The System Is Not Sized Properly
One of the most common reasons that a ductless HVAC system is always on is because it is not sized properly for the space that it is cooling or heating. If the system is too small, it will have to run for longer periods of time to reach the desired temperature.
Conversely, if the system is too large, it will cycle on and off more frequently, which can also lead to increased energy usage and wear and tear on the system. To ensure that your ductless HVAC system is properly sized, consult with a qualified HVAC contractor who can perform a load calculation for your specific space.
The System Is Not Operating Efficiently
Another reason why your ductless HVAC system may be running constantly is because it isn’t operating as efficiently as it should be. There are a number of factors that can impact a ductless system’s efficiency, including:
- Dirty air filters – Air filters should be changed or cleaned on a monthly basis to ensure proper airflow and efficient operation.
- Leaking refrigerant – A leak in the refrigerant line can cause the system to run constantly in an attempt to cool down the space. This issue should be addressed by a qualified HVAC technician
- Poorly insulated home – If your home isn’t well insulated, heat may be escaping through walls, windows, and doors, making it difficult for the ductless HVAC system to maintain a comfortable temperature. Adding insulation can help improve efficiency and keep your home more comfortable year-round.
The System Is Not Set Up Properly
In some cases, a ductless HVAC system may be set up improperly, which can also lead to increased energy usage and shorter lifespan for the unit. Some common installation mistakes include:
- Not sealing gaps around the unit – It’s important to make sure that there are no gaps or openings around the outdoor unit of your ductless HVAC system; otherwise, cooled or heated air can escape before reaching its destination inside your home. These gaps can also allow pests and debris to enter into the unit itself, which can cause damage and significantly reduce efficiency.
- Not leveling indoor units – Indoor units should be level so that they drain properly; otherwise, water could collect inside them and cause damage over time.
How Can I Fix My Ductless HVAC System?
Check the Sizing
The first step in troubleshooting your ductless HVAC system is to check the sizing. To determine if your system is properly sized, you’ll need to calculate the square footage of your home (or the area you want to be heated or cooled) and compare it to the manufacturer’s recommendations for that particular model. If you find that your HVAC system is not properly sized, you may need to replace it with a new one that is better equipped for your space.
Adjust Your Settings
Each room in your home should have its own thermostat so that you can customize the temperature for that space; otherwise, you may find that one room is too hot or too cold while another is just right. Additionally, make sure that all doors and windows are closed when the unit is running; otherwise, cooled or heated air will escape and throw off the desired temperature in that space.
