Best Wall Mounted Air Conditioner Heater Combo – Top 8 Picks!
OUR #1 CHOICE
Senville LETO 12000 BTU Air Conditioner and Heater Combo
If you’re looking for the best wall mounted air conditioner heater combo, the Senville LETO model won’t disappoint. This has 12,000 BTUs, complete with a heat pump and an air conditioner. Moreover, the Senville LETO uses a 4-in-1 mini split system. This includes an air conditioner, heat pump, fan, and dehumidifier. So for a single unit, you’re going to enjoy four different functionalities. This makes the unit worth the splurge if you’re planning to get a new heating and cooling appliance. Aside from that, this AC and heater combo is powered by Alexa. You can use voice control to operate this unit, which is a convenient feature for busy households. You can also use this feature to automate operations, which helps in saving electricity in your home.
This AC and heater unit is bundled with 16 feet of line set as well as communication wire. Just note that professional installation is required to prevent refrigerant leaks. Overall, this trusted AC and heater combo is backed by a 5-year warranty, both on parts replacement and the compressor. Since this is a mini split type, the Senville LETO fits small rooms without looking bulky. It’s also available in higher BTU ratings in case you have a bigger room.
Pioneer WYS012A-19 Air Conditioner and Heater Combo
Another option I recommend is the Pioneer WYS012A-19 Air Conditioner and Heater Combo. It has 12,000 BTUs and is also available in up to 36,000 BTUs for large rooms.
This unit uses a mini split inverter system together with a built-in heat pump. It also boasts a 19 SEER rating and 10 HSPF for optimal energy efficiency.
Moreover, this is bundled with 16 feet installation kit. It’s fully insulated and ready for installation upon purchase. The refrigerant is also pre-charged for line sets between 10 to 25 feet, so you’re free to use a longer line than the standard one included.
Like the Senville LETO, the Pioneer WYS012A-19 also has wireless access and programming features. However, these are sold separately, which is slightly inconvenient for those who are looking for a readily set unit.
Another thing many users like about this unit is its quiet operation. It also works in four modes: heating, cooling, ventilation (fan), and dehumidification. You’ll get four functions at the price of one, which is a big money-saver.
However, I wish the seller also offers a longer line option since the refrigerant is pre-charged for extended lengths. Nevertheless, this is just a minor niggle that many can live with.
DELLA 12000 BTU Air Conditioner and Heater Combo
The DELLA 12000 BTU Air Conditioner and Heater Combo are rated for rooms up to 750 sq. ft. Like most combo units, this one uses a mini split inverter system as well as a built-in pump.
This is AHRI-certified and has a 20 SEER rating and 8 HSPF ratings. It’s guaranteed energy efficient and is equipped with dehumidification and ventilation modes.
Aside from that, this unit is designed with smart settings. It has self-diagnosis, auto defrost, 24-hour timer, eco-energy saving, sleep mode, and I Feel mode. The I Feel mode allows the unit to adjust its heating or cooling based on the ambient temperature, which is very useful in large rooms.
Moreover, this unit has a quiet operation and can adjust its temperature by 60 to 90F to suit your comfort. It also delivers equal airflow throughout the entire room.
In addition, this DELLA heating and cooling combo can work in temperatures as low as -4 degrees. It guarantees efficient heating during winter.
DELLA has its own app where you can explore more features. It also works in both Alexa and Google Assistant for voice control convenience.
Overall, this unit is a great deal, but the instructions that come with it are somewhat confusing. Buyers also noticed that it’s difficult to open and close the cover of the indoor unit.
Klimaire Ductless Air Conditioner and Heater Combo
If you want to save some bucks, you should consider the Klimaire Ductless Air Conditioner and Heater Combo. This has 12,000 BTUs and a 19 SEER rating for guaranteed energy efficiency.
This unit has low ambient cooling and heating, meaning it can produce heat at an ambient temperature of 5F. It will also start cooling once it reaches the minimum temperature threshold, so you’ll remain comfortable across seasons.
Moreover, the Klimaire KSIV series has a self-cleaning function. This works by cleaning and drying the unit’s evaporator to avoid the formation of molds and mildew.
I also like that this AC and heater combo has a Home Away freeze protection feature. It keeps your room’s temperature at 46F when you’re away, so your room remains climate-controlled.
Aside from that, the unit has a Quick Hook design, which makes it easy to mount on walls. You’ll also get a 15-foot installation kit complete with pre-charged refrigerant that can be used on up to 25 feet of line.
In addition, this unit is covered by a 5-year limited warranty. For this price range, I really don’t have major complaints.
OLMO Alpic Air Conditioner and Heater Combo
Another budget-friendly option I recommend is the OLMO Alpic Air Conditioner and Heater Combo. This has a 16.5 SEER rating that, although lower than competitors, is still at par with energy-efficient levels.
Moreover, this unit is equipped with an inverter compressed made by Toshiba. This part is covered by a 5-year warranty together with a 2-year warranty on parts.
Aside from that, this unit uses a pre-flared and three-layer insulated copper line set. The communication wires also have connectors to make them easy to install.
In terms of features, OLMO provides the basics like sleep mode timer, turbo mode, and low ambient cooling. It’s also equipped with a temperature compensation feature to ensure that your zone has a comfy feel.
In addition, this unit can also dehumidify by using the Dry mode. This runs at low speeds, so it doesn’t dry the air too much and too fast.
Overall, this is a quiet AC and heater combo that you can get at a reasonable price. However, you should know that you’ll forfeit your warranty if you decided to perform a DIY installation. OLMO will only honor the warranty if you hire a licensed HVAC installer.
Cooper & Hunter 36000 BTU Air Conditioner and Heater Combo
For those who have a large room and a budget to splurge, the Cooper & Hunter Air Conditioner and Heater Combo won’t disappoint. This has 36,000 BTUs that can cool and heat rooms larger than 800 sq. ft.
Moreover, the heating function of this unit works at an ambient temperature of 5F. It’s also equipped with Whisper Technology for a quiet operation. With that, it’s a good choice for living rooms, nurseries, and bedrooms.
Aside from that, the Cooper & Hunter AC and Heater Combo has a complete installation kit that comes with a 25-feet copper line set. This is the longest line set we’ve ever seen offered in the same package compared to other options reviewed here.
When it comes to warranty, the compressor of this unit is covered for 7 years. Meanwhile, the parts have a 5-year warranty. Just make sure that you hire professional installers to keep the warranty coverage intact.
Overall, this is a heavily efficient unit and the remote control has a long range of up to 20 feet away or more. Some users even say that this Cooper & Hunter unit is as good as the one from Mitsubishi but for half the price.
DAIKIN 24000 BTU Air Conditioner and Heater Combo
Another premium option you can consider is the DAIKIN 24000 BTU Air Conditioner and Heater Combo. This has a 17 SEER rating and 9 HSPF for heating made by a tried and tested brand.
This unit is suitable for homes or rooms with floor areas up to 1,500 sq. ft. You can also use the Turbo mode to cool or heat a big room fast.
Inside the unit is Daikin’s proprietary titanium apatite photocatalytic air filter. It deodorizes and filters the air, so you can breathe easier.
This is paired with a Blue Fin protection feature that uses hydrophilic fins that allows water to drain well to the pan. Overall, this feature prevents coil freezing and it also prolongs the coil’s lifespan.
Moreover, this DAIKIN AC and Heater Combo has a POWERFUL button on its remote. You can use this to boost the heating and cooling capacity of the unit for 20 minutes. This comes in handy if you need to cool or heat a place as fast as possible.
Keystone 12000 BTU Air Conditioner and Heater Combo
If you’re looking for a through-the-wall unit, I highly recommend the Keystone 12000 BTU Air Conditioner and Heater Combo. This is suitable for rooms not bigger than 550 sq. ft.
Moreover, this unit has a 9.5 EER rating, which is energy-efficient enough even for extended use. And aside from heating and cooling, this Keystone model can also dehumidify your room by removing up to 2.5 pints of moisture per out.
I also like that a thermostat was built into the remote control. This has a Follow Me sensing control, which ensures that your zone is fully cooled or heated as you like.
In addition, this unit is compatible with any sleeves measuring 24” to 27”. It’s easy to install and the package already includes an installation kit and foam seals in case you need to tweak your existing sleeve. Keystone also sells a matching sleeve for this unit.
Overall, this is a great unit for apartments and small rooms. The only niggle here is that since the unit is located inside, you’d have to deal with the noise.
How to choose a wall mounted air conditioner heater combo
There are many options when looking for a heating and cooling combo. But to ensure that you’re getting the best value for your money, you should consider the following aspects first:
✔️Check the BTU requirements
One thing that sets air conditioner and heater combos apart are their BTU rating.
BTU stands for British Thermal Unit, which is used to measure how much energy the AC uses to remove heat in an hour. The suitable BTU rating for your home depends on its floor size.
It’s important to match the size of your home to the BTU rating of the AC unit to ensure energy-efficient operation. In other countries, this is measured by horsepower or hp. And in conversion, 1 hp in air conditioners is equivalent to around 2,545.46 BTUs.
To get the proper BTU rating for your home, you need to measure the floor area by the square foot of the room where you plan to install the unit.
In general, a room that’s smaller than 150 sq. ft. needs at least 5,000 BTUs. Meanwhile, bigger ones that are around 500 to 600 sq. ft. should use a unit with 12,000 BTUs. The bigger the room is, the higher the BTU rating should be.
Those with south-facing rooms must consider upgrading to the next higher BTU rating available. This is to compensate for the intense heat that the air conditioner will have to deal with.
Also, you should check the BTU rating for the heating capacity. Just like the one in cooling, it should be based on your floor area and how cold your room gets during winter.
✔️Consider the controls
Another thing you should check is the controls of the AC and heater combo you’re going to buy. A remote controller is a standard, but you can also find models equipped with WiFi connectivity.
Moreover, there are wall-mounted air conditioners and heaters that are even programmed with voice control. These units can be controlled using Alexa and Google Assistant.
✔️Mind your wall’s thickness
If you’re opting for through-the-wall models, you have to consider the thickness of your wall. If your wall is thinner than 8 inches, you need sleeves with cooling vents both on the sides and back.
When in doubt, you should check the manufacturer’s instructions to ensure that the sleeve you’re using is suitable for the unit.
✔️Opt for energy efficiency
Air conditioner and heater combos use a lot of electricity. This is why you should always opt for energy-efficient units if you’re buying a new one.
Aside from having the Energy Star seal, you should also check the unit’s Energy Efficient Rating or EER. There’s also a one called Seasonal Energy Efficient Rating or SEER.
In general, a higher rating number indicates that the unit is energy-efficient. And overall, those with the Energy Star seal usually have the highest energy efficiency rating. This translates to cost-efficient operation and lowers electricity bills on your part.
✔️Decide about the price range
Lastly, you should set a budget that you’re willing to spend for the best wall mounted air conditioner and heater combo. This way, you can filter out your options and remove those you can’t afford.
But if you want a premium AC and heater combo, I recommend investing in it. While the upfront cost is intimidating, it will pay for itself in the long run due to energy efficiency and overall comfort.
Frequently Asked Questions
Q: Do wall air conditioners also heat?
A: There are wall-mounted air conditioners that can also heat. This is possible since the condenser unit is also equipped with a heat pump. With that, you can use the unit both during winter and summer to control your indoor temperature. They are often installed like any split-type model, though there are also through-the-wall options.
Q: Are wall units more efficient than central air?
A: Wall-mounted units are convenient and cheaper than central units. However, if you have a large house, wall-mounted types may not be the most efficient. It all boils down to your needs, your budget, and the overall upkeep of the cooling system you’re going to get.
Q: Are wall-mounted units worth it?
A: Wall-mounted units are worth it for those who want a convenient way to cool and heat their homes. It doesn’t have ducts, so installation is much easier. This is also cheaper, but make sure that you get one with the right BTUs based on the size of your home, weather in your area, and so on.
Q: How long do wall air conditioner units last?
A: On average, a wall-mounted air conditioner can last for around 15 to 20 years. This period can be shorter if the AC is used regularly and heavily. The level of upkeep during the years as well as the overall quality of the unit will also impact its lifespan. Nevertheless, one thing is for sure: AC units won’t last forever.
Q: What’s the difference between a wall-mounted and window-mounted AC?
A: Wall-mounted air conditioners are attached to the wall. There’s no need to create an opening since the AC unit is drilled inside the house. Meanwhile, window-mounted types need an opening, usually a window where the coil side needs to be protruded. It doesn’t require any piping or ductwork. However, it’s bulky and will eat up space on your window, not to mention that it will block your view.
The best wall mounted air conditioner heater combo will keep you comfy across seasons. Instead of buying separate HVAC appliances, you can get this one to enjoy convenience.
And just like any cooling or heating unit, it’s important to match your option with the size of your room as well as your budget.
