One of the most challenging steps before the installation of a commercial air conditioning system is to determine the correct size of the unit that you should buy. Some owners of commercial buildings do not consult HVAC professionals before making a purchase, so they may end up with a unit that is too large for the requirements of that commercial building. This article discusses some of the risks that you are likely to face if you install an oversized AC system.

Humidity Issues

Air conditioning systems do two things simultaneously; they cool or heat the building and remove humidity. An oversized system will cool the room quickly and stop working. This will give the evaporator coil a limited chance to remove moisture from the indoor air. Properly sized AC systems run for a relatively long time before cycling on and off. This prolonged run time moves the indoor air over the evaporator coil for a longer time resulting in effective humidity control. Thus, an oversized system will create ideal conditions for the growth of mould since the building will always have high levels of humidity.

Short Component Life

AC system components such as the compressor will break down frequently. This wear will be the direct result of very frequent stop/start cycles (described earlier) that overwork the moving parts of the compressor. Thus, you will incur higher AC repair costs if you made the mistake of installing a unit that is larger than what was required in your commercial building.

Energy Waste

An oversized AC also hurts your earnings on a monthly basis. The short start/stop cycles also have an impact on the energy consumed by the system. The compressor uses a lot of energy to start. It therefore follows that much more energy will be consumed by the AC system if the start/stop cycle is short. That extra money spent on energy is money that should be remaining in your pocket.

Noise

Air conditioning systems emit varying levels of noise as they operate. A larger unit will generate more noise when compared to the noise level that would have been generated by a smaller unit. This may compel you to incur additional costs to provide noise attenuation systems so that the tenants of your commercial building do not complain that the noise is affecting their commercial activities.

Think like an astute businessperson. Hire a professional to assess your AC needs correctly so that you install a commercial air conditioning system that will not expose you to the risks above.
