Wall Mount Air Conditioner

Wall Mount Air Conditioners

Wall mount air conditioners are a package HVAC system that mount vertically to the exterior of a building.  While they can go on any structure with a wall, as a self contained package system they’re very popular on buildings that are manufactured in one place them moved to another.  Capable of heating, cooling, ventilating, economizing and dehumidification, wall mounts are a great option when interior wall space is limited or you don’t have rooftop or remote pad mount options.  Simple to install upgrade and replace, vertical wall mounts are available in standard duty, Industrial HVAC as well as fully custom pressurization and explosion proof configurations.

When compared to a pad or roof mounted unit, wall mounts are able to deliver a lot of cooling in a relatively small package, even in the bigger 10, 15 and 20 Ton sizes.  Installed on the wall, the need for ductwork is purely optional as most elect to finish the installation with a supply louver and return grille on the inside of the space.


While we build many wall-mounted air conditioners from scratch, for hazardious location modification oftentimes the fastest and most cost efficient way is to buy a standard duty Bard unit and make the necessary modifications.  To see a full HVAC catalog of what bard offers click here.


Fractional tonnage air conditioners for electrical cabinets from sizes 1,000 to 19,000 BTUh are also available.  VoltAire cooling is an American Engineered unit that is produced in Orange County Florida

Typical Uses Include:

Telecommunication shelters

Portable buildings

   Construction offices

   Portable Classrooms

Shipping containers (conex)

Pump Stations

Electrical Enclosures

Wastewater Treatment Plants

Ships, tankers, and Offshore Drill Rigs

Gas Analyzer shelters

Schools (Brick and Mortar)

Due to the simple form factor, Wall Mounts are easily modified for hazardous, corrosive, classified or explosion proof specifications.  Some modifications like pressurization are even able to be done in the field or when leased fleets come back in for maintenance and refurbishing. Customizations for wall mount units include:

Explosion Proofing

Can be done on the interior section, exterior section or both to the Class, Division & groups necessary. Explosion proof exhaust fans and enclosures are also available


Can be done in the factory or in the field with optional fresh air stacks.


Corrosive environments

Custom HVAC

Unique systems designed, engineered and specified to meet your exact requirements.  Lead time from order to installation in 6-8 weeks*  (*some of our suppliers may take up to 10 weeks for large units)


All of our wall mounts are available as heat pumps but most customers elect for cooling with electric back-up heating coils. The wall mount is versatile in that we can add more heat into a building if need be. Steam, water and glycol are also available if your site permits.


Standard sizes are generally 6,000 to 70,000 BTU (0.5-6.0 Ton), and 70,000 to 240,000 BTU (6.0-20.0 Ton).  All units from the 1 ton to the 40 ton are built to order. We are a custom air conditioner manufacturer and welcome projects that might scare off the other guys. 


Ventilation is unique to each location.  Some situations necessitate blank-off plates to eliminate the chances of external air getting inside the conditioned space,  keeping external factors like dust, humidity, toxic or corrosive air at bay while, other times fresh air is needed to pressurize a building or provide fresh air to a structures occupants or dilute any gas build up from batteries or other dangerous gas’.  Fresh air can also be used to cool a building when conditions permit with an economizer.  Wall mounts are a great platform for the varied ventilations needs and options.


Every air conditioner can dehumidify but it needs to be “cooling” to condense the water onto it’s coils to remove the moisture out of the air. What if your space is comfortable but you still need to remove humidity?  Factors including the ambient temperature and unit size control when the air conditioner can operate in cooling mode but if you have tight tolerances for dehumidification additional steps can be taken to ensure humidity levels are kept down.  Recycled heat aka “hot gas dehumidification” is known to be the most economical way to dehumidify but does come with higher upfront costs.  This method requires a second coil on the back side of your (cold) evaporator coil to recycle the hot gas from the compressor back into the air, bringing the air temperature back up the the temperature it was before it cooled on your evaporator coil. A second method is with Electric reheat dehumidification.  It’s upfront costs are much lower than hot gas dehumidification but require a much larger circuit breaker and energy use will be much higher during periods of active dehumidification because you use a heater to bring the temperature up after air passes the cold evaporator coil.
