Heater Air Conditioner Combo Wall Unit Buying Guide

mounted ACs come in all shapes and styles. The following considerations should help you choose the right one for your home.

What is a Wall Mounted Air Conditioner?

As the name suggests, a mounted air conditioner is an AC installed on the wall. They’re ideal for small spaces such as bedrooms, living rooms, offices, and small stores.

They are usually installed at a position and height to supply air (or heat) evenly in all directions without obstructions.

Wall Mountable vs. Through-the-Wall ACs

Wall mountable air conditioners shouldn’t be confused with the through-the-wall unit or window air conditioners.

While most through-the-wall air handlers eventually end up hanging from the wall, the two AC models are slightly different. A mount AC refers to any AC type where the indoor air handler is installed on the wall.

For example, the indoor unit could be attached to the wall via a metal frame and a few screws, or part of the wall may be pulled out and the unit installed into the wall.

Meanwhile, a through-the-wall unit is any AC where the indoor and outdoor condenser are connected via a hole in the wall. Often, you’ll only need a small hole measuring no more than five inches in diameter.

The tubes and electrical wiring connecting the indoor air handler and the outdoor condenser pass through this hole.

In the end, though, it’s possible to have a through-the-wall wall-mounted AC. Still, it’s essential to understand the difference.

What Makes Wall-Mounted ACs Different?

Mounted ACs are different from other air conditioners in several ways. From design to features and even performance, they are unique.

With regards to design, most of them comprise three main components – an outdoor compressor/condenser, an indoor air handler, and connecting tubing.

For example, window air conditioners’ outdoor units are typically larger, while the indoor air handler is smaller and more beautifully designed to fit into the indoor decor.

Wall units are permanent fixtures that cannot be moved from one spot in the room to another. When it comes to features, mounted air conditioners have the same functions as other air conditioning units – to cool your home.

As such, they have the same features as most air conditioners. The difference, however, is that advanced wall-mounted ACs come with many additional convenience features to ensure greater round-the-year comfort.

Advanced wall-mounted units, for example, have heat pumps, thus can function as an air conditioner and heater.

Most of them also function as dehumidifiers and even ventilators. These units also feature; remote, Wi-Fi control, auto restart, and many other extras.

As for performance, mounted air conditioners are some of the most energy-efficient HVAC systems. They consume little electricity and produce consistent amounts of cool breath or heat to cool or warm your rooms.

Indeed, nearly all air conditioning units in this category are Energy Star certified and come with very high Seasonal Energy Efficiency Rating (SEER) and Heating Seasonal Performance Factor (HSPF) ratings.

The only downside is that a dual-purpose wall-mounted AC + heat pump alone can’t provide you with sufficient heat during the peak of a cold winter.

Reasons Why You Should Use a Wall-Mounted Air Conditioners

There are endless reasons why you should consider wall-mounted air conditioners over other types of AC units. These include;

  • Easy to install: One of the biggest advantages of mounted ACs is that they’re very easy to install. There are only two main tasks involved in installing a wall-mounted AC, and both tasks are relatively simple. First, you’re required to drill a hole through the wall and connect the indoor unit and the outdoor condenser via that hole. Secondly, you’re required to install the AC sleeve into the wall and screw the indoor air handler to the sleeve. If you choose an AC that uses a slide-out chassis sleeve, you can DIY the entire installation.
  • All-in-one HVAC function: As we already mentioned, most wall-mounted air conditioners don’t just work as AC uni. Instead, most of these appliances are all-in-one heating, cooling, and air conditioning (HVAC) systems that prove useful throughout the year. During warm weather, they work as window air conditioners and can also be used as dehumidifiers and ventilators. When the cold season sets in, they become a supplemental heat source.
  • Fairly priced: Unless you have a big house and need a huge AC, wall-mounted air conditioning units should be within your price range. The smaller, one-ton models often cost less than $1,000, with some priced as low as $600. This represents an excellent investment for appliances that promise round-the-year cooling. Moreover, when you consider that the AC could also serve you as a supplementary heat source, dehumidifier, and ventilator at different times of the year, the initial investment feels like a bargain.

Features to Look For in a Mounted Air Conditioner Heater Combo

As with other air conditioners, the three most important factors to consider when choosing an air conditioner and heater are size, efficiency, additional functions, and features.

  • Size: The size of the AC determines how much space it can cool at any given time. A small AC will only efficiently cool a small space. A one-ton (12,000 BTU) AC, for example, is designed for spaces in the 400-500 Sq. Ft. range. If you intend to use the AC to cool a larger space, find a larger AC for cooling and heating.
  • Efficiency: All ACs have an Energy Efficiency Rating (EER), with some having an additional rating known as Seasonal EER (SEER). We recommend aiming for an AC with a SEER rating of 15 or higher. If you can get close to 20 SEER, that would be brilliant. The great news is – most mounted air conditioners have 17+ SEER ratings!
  • Additional functions: As we’ve seen, many wall-mounted air conditioners double up as heaters, thus can also serve as a supplemental heat source. But, that’s not all. Some advanced mounted mini splits also work as dehumidifiers and ventilators. Always lookout for these multi-functional units.
  • Features: Finally, although the mounted air conditioner and heater share a lot of features, you should keep an eye out for any additional convenience features. Something like remote control, for example, gives you greater control over the AC. Multiple modes (e.g., Sleep Mode and Auto Mode) also make your work easier. A timer and solid warranty are other features you want to consider.

What are Ductless Mini Split Wall Mounted Conditioners

A ductless AC combo doesn’t use air ducts. As such, you don’t need to install ductwork. Ductless AC units are mostly mini-splits, meaning that they comprise at least two components – an indoor unit (known as an air handler) and an outdoor component (known as a compressor or condenser).

The term “mini” refers to their small size (especially the indoor air handler). In mini-splits, the air handler is much smaller compared to indoor units of other AC types.

Therefore, a mounted ductless mini-split is any ductless mini split where the indoor unit is designed to be installed on the wall.

Benefits of Wall Mounted Air Conditioner Heater Combo

Wall-mounted ductless mini-splits come with a range of advantages. For one, the ductless nature ensures minimal energy loss.

Indeed, studies show that ductless mini-split systems guarantee 30% energy savings every year. Moreover, it is of the best quality when it comes to energy saving.

Another key benefit of ductless mini-splits is the lower initial investment. Purchasing and installing ductwork can be very expensive. Depending on the home/space size, you may need an extra $2,000+ to buy and install the ductwork.

A ductless AC unit saves you that cost. Finally, ductless mini splits are also quieter and much more suited to living areas due to the design.

How To Install a Wall Mounted Air Conditioner

Installing a wall-mounted air conditioner isn’t difficult (though professional installation is still recommended). If it’s a typical through-the-wall wall-mounted AC, the first step is to identify the best location for the outdoor condenser.

The user manual should provide more guidance on this. Once you’ve identified a great spot, drill a hole in the wall. Ensure to check for plumbing or electrical wiring within the wall before drilling.

Then, the line set (refrigerant tubing) and electrical wires connecting the outdoor unit to the indoor AC are passed through the hole.

With that done, all that’s left is to identify a great spot for the indoor air handler, mount the sleeve, and screw the air handler to the sleeve.

It’s a simple process that many homeowners now DIY. But, to avoid any problems and keep your warranty intact, it’s best to leave the job to a professional.

Wrap Up

So, there you have it – a complete guide on buying the best mounted air conditioner heater combo. One thing you’ll probably enjoy when doing your shopping is that most modern wall-mounted mini-split air conditioners come with an in-built heat pump.

So, you won’t spend too much time checking which models have a heat pump and which ones don’t. As with all air conditioners, we must, again, stress on size. Once you get the size right, everything easily falls into place.

Happy shopping!
