Can A Ductless Mini Split Be Used For Heating?
In a word- Yes. Many people assume that ductless mini-split systems are great air conditioners, but did you know they can be great heaters as well? We have installed many mini splits in the Abingdon, VA area, and the surrounding neighborhoods. One of the things homeowners enjoy so much is the versatility of their mini splits, being able to use them all year long!
Understanding A Ductless Mini-split System
A ductless mini-split system is a heat pump. It consists of two main units, an indoor air handler, often called a head or cassette, and an outdoor compressor unit, which connects via lines to the indoor air handler. These are like the components of a traditional HVAC system, but they are smaller and can be placed at a distance from one another, unlike a traditional unitary system.
As heat pumps, these systems can both heat and cool your space- it’s all about the direction you want the heat to go! Mini-split systems tend to work well down to about 0oF, so if you live where it gets down below that temperature regularly, you may need a back-up heating system. However here in the Chilhowie area, our average lows, even in the middle of January, are in the 20’s, making a mini-split ductless heat pump system a great way to heat and cool your whole home for year- round comfort.
How Do Ductless Mini Splits Heat My Home?
During heating, the system works by:
- Extracting heat from outside air (even when it’s cold) and moving it indoors.
- The outdoor unit absorbs heat from the air and transfers it to the refrigerant.
- The refrigerant is then compressed to raise its temperature and pumped to the indoor unit(s), where the heat is released into the room.
In the Summer, this process just works in reverse, where the heat is extracted from the indoor air and pumped outside, cooling your home!
Mini Split heat pumps are about 70% more efficient than baseboard heaters and they distribute the warm air evenly throughout your space, making them a much better way to stay comfortable while keeping your energy bills low all winter.
Things to Know If you want to use a Mini-Split System for Heating
- Choose the Right Capacity:
- The mini-split system must be properly sized for your space. A system too small will struggle to heat the room, and one that’s too big will cycle on and off frequently, giving you less efficiency.
- Consult with an HVAC professional, like our team here at Complete Comfort to determine the right capacity based on the square footage and insulation level of your home.
- Set the Thermostat to Heating Mode:
- Most mini-split systems have a remote control or wall-mounted thermostat. Switch the system to heating mode.
- Set the desired temperature for each zone (room).
- Ensure Proper Placement of Indoor Units:
- Place the indoor air handlers where they can distribute warm air evenly. Avoid positioning them near windows or in places where airflow might be obstructed.
- Monitor for Cold Weather Performance:
- Mini-split systems can work in temperatures as low as 0°F (-18°C) or even lower with cold-climate heat pump models. Make sure when you purchase your system you know whether it can handle the extreme temperatures of your area. Here in Virginia, we don’t often need the cold-climate units, but they are available.
- Maintain the System Regularly:
- Clean or replace filters in the indoor units regularly to ensure efficient operation.
- Make sure the outdoor compressor is clear of snow, debris, and ice during winter, as these can obstruct airflow and reduce efficiency.
- Use Ceiling Fans for Heat Distribution:
- To help distribute the warm air, you can use ceiling fans set to rotate clockwise at a low speed. This pushes the warm air near the ceiling back down into the room.
Advantages of Using a Mini-Split for Heating
Here at Complete Comfort, we’re seeing more and more customers choose ductless mini-split systems because:
- Energy Efficiency: Mini-splits are generally more energy-efficient than traditional heating systems because they don’t lose heat through ductwork. Increased efficiency means getting the comfort you want, without increasing your energy bills!
- Zoning Flexibility: You can control the temperature of individual rooms independently. Each individual indoor air handler unit can be controlled independently, meaning you can adjust the comfort level in the family room while letting someone else adjust the temperature in another room, or even shut the system off in say, a bedroom, while no one is there. This zoning helps you heat and cool the areas you’re using, and not waste energy in spaces that you’re not.
- No Need for Ductwork: Ductless mini-split systems are ideal for homes without existing ductwork, or to heat specific rooms that can be difficult to heat and cool, like additions, basements, sunrooms, garages, third floors, and the like.
Mini-split systems can be terrific as supplemental heating and cooling for your home, or as a whole home heating and cooling solution. A single outdoor unit can power up to 8 indoor air handlers, delivering custom comfort to each room, every day of the year.

When a homeowner gives us a call for service on their HVAC system, we know they want to get up and running as soon as possible. The owner of this lovely single family home in Marion, VA, in Spottswood Place, wasn’t getting the AC comfort she wanted, and thought she might have a refrigerant leak of some sort. We sent out one of our best technicians, Alex, to see what the problem was.
The Homeowner realized her system was getting to the point it should be replaced, so she asked us to give her a quote on a new system. Nate came out and looked at her system and performed a “load calculation” on her home. This involves calculating the square footage, where you live, accounting for windows, insulation and more to get a sense of how big of a system you might need for your home.
Here at Complete Comfort, we know the last thing any homeowner wants to be thinking about is their electricity. Just like your car, you just want it to work, and hopefully not cause any problems, because problems tend to be expensive. The owners of a home in Brumley Gap in Abingdon were no different. But like many homeowners in the area, they lost power during storms, and big storms seem to be coming more frequently.
The system also includes Mobile Link Wifi Remote Monitoring, which lets you monitor your generator’s status and get alerted to when it kicks on via smart phone app. This means even if you’re on vacation, you’ll know your home is protected. A few years ago, a friend of ours was away and the power went out for 5 days during an extended winter storm, causing endless worry about pipes freezing and an expensive saltwater fish tank they had as well, among other worries about their home. If they had a Generac, they would have known their home was fine whether they were there or not!
Right now is the time of year you should be scheduling heating service. The summer is on its way out, and before you know it, it’s going to start getting colder. In this article, we are going to go over why you should schedule heating service for your system.
The summer is starting to wind down, and we know how quickly the cold weather is going to get here. This is why we want to start telling homeowners about the benefits of furnace service.
As your furnace creates warm air, it then pumps it into your ductwork and throughout your home. If the furnace is dirty, the air in your home could be dirty as well. Over time, dust, dirt, and other contaminants can accumulate in your heating system, and if the system isn’t properly cleaned, these irritants can get into your air.
You’ve been using your air conditioning system all summer long, pumping air through the system. This means your air filter has been working overtime, trapping all the airborne irritants that make their way into your HVAC system.
Curling up on the couch for some TV with a blanket and some popcorn is a great feeling. So bust out those throw blankets! As the nights get colder, a few throw blankets add a nice aesthetic, and also help you stay cozy on those chilly nights.
We are entering the stormy season, generally between August and October, and with that comes power outages. A summer storm is nice sometimes, but losing your power is never a good time. We want to tell you a little more about why installing a generator in your home is a good idea.
We recently installed a new air conditioning system for a business in Kingsport, TN. One of the best compliments we can receive from a customer is when they recommend us to their friends and family. That was the case with this project, which we were happy to be a part of.
The last thing any business owner wants to do is spend money unnecessarily. In some cases, you may be able to get away with not cooling a storage space, depending on what was being stored there. In lots of cases with businesses that have a warehouse, there are materials that you don’t want to expose to extreme heat or cold.
During the Summertime, your air conditioner is one of the most important components of your home. It keeps you cool and comfortable, while also having a direct impact on your energy bills. After years of operating, you will likely run into some issues, and may need to consider replacing it after some time. Knowing the signs of when you should replace your AC is important.
If your air conditioner uses Freon (R-22) refrigerant, it’s definitely time to consider a replacement. As of 2020, R-22 is being phased out due to environmental concerns, and its production and import have been banned in many place, including the United States. As a result, the cost of R-22 has skyrocketed, making repairs involving this refrigerant increasingly expensive.
Air conditioning is one of the essential systems of your home that help you stay comfortable in the Summer. Almost everyone loves to have that AC blasting when they walk in the door from a hot day. The thing people hate about their air conditioners are the costs associated with them. I know when I was growing up, my dad waited until the very last second to turn the AC on, so he could avoid those large energy bills that come along with running the AC. It leads us to the question: Is it cheaper to run an old AC or install a new one?
