What to do if your mini-split is not heating

Mini-Split Not Heating: A Mystery Solved!

Hey there, friends! My name is Russ, and I’m one of the managers over at Reliable Appliance & HVAC. Today, we’re going to talk about a common HVAC problem — a Mini-split not heating!

Let’s get started.

What Is A Mini-Split System?

Before we dive into the problem, let’s define what a mini-split system is. It’s an HVAC system that has two main components: an outdoor unit that does the heavy lifting, and an indoor unit that delivers cool or warm air to the entire room. It’s a fantastic option to consider if you want zoned heating, meaning you can control the temperature of specific rooms.

The Phone Call

Early on a chilly autumn morning, we received a call from a customer named Emily about her Mini-Split Not Heating. Emily actually lives in Orange County, California. She explained that her room stayed cold, even with her mini-split system running all night. She said she woke up freezing and decided to contact us to fix the problem.

The Diagnosis

Our technician, Oscar, arrived at Emily’s house within two hours of the phone call. Upon arrival, Oscar noticed that the outdoor unit and indoor unit seemed to be working correctly. No bad signs. That’s when Oscar ran some diagnostics.

To diagnose the problem, Oscar first turned off the mini-split system completely. He opened the front panel of the indoor unit and checked the temperature of the evaporator coil. The coil was icy and completely frozen, which made Oscar suspicious that the refrigerant might be low.

After that, Oscar checked the refrigerant level using his gauges, and he discovered that the refrigerant was low. The refrigerant is essential for the refrigeration cycle, which is what enables the mini-split system to do its work. When the refrigerant is low and cannot complete the refrigeration cycle, the evaporator coil becomes too cold and freezes up, which is why the indoor unit wasn’t heating up in Emily’s case.

The Solution

After the diagnostics, Oscar gave Emily a quote to fix the problem, and she accepted it. Oscar then went ahead and refilled the refrigerant to the manufacturer’s recommended factory level. Oscar also confirmed that the air filter was relatively clean and changed it to ensure that the evaporator coil wouldn’t freeze up again, causing the ductless mini-split not to heat up.

After testing the system, Oscar was confident that there were no more issues, and he left a happy customer’s house.


Let’s get down to brass tacks — the costs. Emily decided to fix her mini-split system, which included the following costs:

Part Costs
Refrigerant $450
Air filter $25
Labor fee $300

Emily paid a total of $775 to repair her mini-split system.


And that’s it! Emily’s mini-split system was successfully repaired thanks to Reliable Appliance & HVAC’s technician Oscar. Now Emily can sleep soundly, knowing her HVAC system is heating up her room as it should.

We hope this unique story has been helpful for you to understand why a Mini-Split Not Heating problem can occur, and how Reliable Appliance & HVAC fixed it. If you have any other HVAC-related issues, be sure to give us a call!

Mini-Split Not Heating: Preventive Measures and Recommendations from Manufacturers and HVAC Technicians

Do you own a mini-split Air Conditioning (AC) system and are worried about it not heating effectively? Do you want to prevent breakdowns and enjoy uninterrupted warmth during the cold months? Then you need to take preventive measures and listen to the recommendations of manufacturers and HVAC technicians. At Reliable Appliance & HVAC, we have helped many homeowners in San Diego avoid mini-split not heating issues. In this article, we share with you some of the preventive measures and recommendations to keep your mini-split system heating efficiently.

Regular Maintenance Checks

The popularity of mini-split AC systems owes much to their easy installation and operation, making them a top choice for many San Diego residents. However, like any other AC system, mini-splits require regular maintenance checks to work at optimal levels. Manufacturers and HVAC technicians recommend scheduling regular maintenance checks for the units. A maintenance check should involve a thorough inspection of the components and cleaning. Experienced technicians should carry them out to ensure efficient heating.

Proper Use and Operation

Another recommendation to avoid mini-split not heating issues is to use and operate the system properly. Some homeowners overload their units with excessive heating, resulting in breakdowns. Always ensure you use the system within the manufacturer’s recommended capacity. Watch out for signs of overheating, such as unusual noises and smells, and turn off the system immediately if you notice anything out of the ordinary. If the problem persists, call in the professionals at Reliable Appliance & HVAC for immediate assistance.

Replace Old Units

Mini-split AC systems have an average lifespan of between 12-15 years. After this period, homeowners might start experiencing problems with heating. The best course of action is to replace old units with new ones. Follow the manufacturer’s recommended guidelines for replacing older units. When you are unsure, enlist the help of Reliable Appliance & HVAC technicians to assess whether a replacement is necessary.

Clean Filters Regularly

Dirty or clogged filters are a recipe for mini-split not heating issues. HVAC technicians’ recommendations include cleaning or replacing filters regularly, even during operation’s peak periods, like winter. Clean filters ensure your mini-split AC system works correctly, providing you with warm living space during the cold season.

Hire Professionals for Installation and Repairs

Mini-split AC systems are complex systems, and installations or repair needs to be handled by professionals. Hiring inexperienced technicians or attempting a DIY installation might end up damaging the system or causing safety risks. Reliable Appliance & HVAC technicians have the expertise and experience to handle complex installations and repairs.

In conclusion, minimizing the risk of mini-split not heating issues entails taking proactive measures and seeking professional advice from Reliable Appliance & HVAC. Regular maintenance checks, proper system use, replacing old units, cleaning filters regularly, and involving professionals in installations or repair are some of the recommendations from manufacturers and HVAC technicians. By following these tips, you will enjoy uninterrupted warm living spaces throughout the winter season. Contact us at (866) 516-1222 or visit our San Diego offices for more information.
