Common Mini Split Heating Problems We Solve
Mini-split systems are highly efficient and reliable, but like any complex piece of machinery, they can encounter issues, especially with their heating functions. Our Corona technicians are experts at identifying the root cause of these problems and implementing lasting solutions. We frequently address the following issues:
Your Mini Split is Blowing Cold Air in Heat Mode
This is one of the most frustrating problems. It often points to a malfunction in the reversing valve, the component responsible for switching the system between cooling and heating modes. It could also be caused by low refrigerant levels, a faulty thermostat, or a sensor failure that is preventing the system from properly entering the heat cycle.
The Unit Produces Weak or Inadequate Heat
If your room never seems to get warm enough, the cause could be simple or complex. A dirty air filter or a clogged indoor or outdoor coil can severely restrict airflow and heat exchange. Low refrigerant charge or an undersized unit for the space can also lead to poor heating performance.
You Hear Strange or Loud Noises
Your mini-split should operate quietly. If you hear gurgling, rattling, buzzing, or grinding sounds, it’s a clear signal that something is wrong. Gurgling can indicate a refrigerant line issue, while rattling may point to loose components. A buzzing or grinding noise is more serious and could mean a problem with the fan motor or compressor, which requires immediate attention.
The Indoor Unit is Leaking Water
While leaks are often associated with AC mode, they can also occur during heating. A clogged condensate drain line or a cracked drain pan can cause water to back up and leak from the indoor unit. In colder conditions, it could also be a sign that the outdoor coil is freezing and not defrosting properly.
There's a Bad Smell Coming From the Unit
A musty or mildewy odor often indicates the growth of mold or bacteria on the indoor coil or in the drain pan, which needs to be professionally cleaned. A burning smell might mean dust has accumulated on the heating elements or, more seriously, an electrical issue that poses a fire hazard.
The System Turns On and Off Frequently (Short Cycling)
When a unit short cycles, it not only fails to heat your space properly but also endures excessive wear and tear and consumes more energy. This is often caused by a dirty filter, an incorrectly placed thermostat, or low refrigerant levels.
What You Can Check Before Calling for Service
Before you schedule a professional repair, there are a few simple troubleshooting steps you can perform that might solve the problem. These checks are safe for any homeowner to perform:
- Check Your Remote Settings: Ensure the remote is set to “HEAT” mode and the temperature is set several degrees higher than the current room temperature. Also, check that the fan speed is set to "AUTO" or a higher setting.
- Inspect and Clean the Air Filters: A clogged filter is the most common cause of heating and cooling problems. Remove the filter from the indoor unit and clean it according to the manufacturer’s instructions. Most are washable with lukewarm water.
- Examine the Outdoor Unit: Walk outside and look at the condenser unit. Make sure it is clear of any debris like leaves, branches, or dirt that could be obstructing airflow. In colder weather, check for any significant ice or snow buildup.
- Reset the System: Sometimes, a simple power cycle can resolve a minor electronic glitch. Turn the mini-split off at your home’s circuit breaker, wait for five minutes, and then turn it back on.
If these steps do not restore your heat, or if you notice any signs of a refrigerant leak (a chemical smell or oily residue), hear loud mechanical noises, or the unit repeatedly trips the circuit breaker, it is time to call for professional service immediately.

Should You Repair or Replace Your Mini Split?
This is a critical question for homeowners with an older or frequently malfunctioning unit. We can help you make an informed decision by evaluating several factors:
- Age of the System: Most mini-split systems have a lifespan of 12-15 years. If your unit is approaching or has surpassed this age, investing in a new, more efficient model may be more cost-effective in the long run.
- Cost of the Repair: A common guideline is the 50% rule. If the cost of the repair is close to or exceeds 50% of the cost of a new system, replacement is typically the better financial choice.
- Frequency of Breakdowns: If you find yourself calling for repairs every winter, the cumulative cost and inconvenience can quickly add up, making a replacement a more reliable option.
- Energy Efficiency: Technology has advanced significantly. A new ENERGY STAR® rated mini-split can be drastically more efficient than a model from a decade ago, leading to substantial savings on your monthly utility bills.
