So, what is the best air conditioning for businesses?

The difference between a residential and a commercial air conditioning unit is with the horsepower. With the right horsepower the company will save thousands. Listed below are some of the major differences between the two and why it’s best to opt for commercial than residential air conditioning units.



Residential and commercial systems serve different requirements of different areas, the amount of power they produce differ as well as with thermostats, fan, compressor, evaporator and blower. Residential units are smaller than commercial, so it is best to consult with a specialist regarding the size.



While a private HVAC unit is ordinarily set in the deck/yard or the sides of the house, a company’s HVAC framework is put in swamp coolers or on the structure’s rooftop for the following reasons:

  • A HVAC framework that is set on the rooftop makes an incredible space sparing arrangement.
  • It keeps away from clamor contamination in the structure.
  • It is an ideal answer for maintaining as none of the activities are interrupted during fixes and substitutions.




Aside from size, residential and commercial systems also differs in their form. Commercial systems are more flexible as they need to adapt to the type of building, number of residents and the use of the building even considering the duration of stay whether temporary or permanent. That is why commercial systems are built with complex functions compared to residential units as they require less power to prevent exhaustion.



Normally, the drainage system in a commercial system is larger than residential. Residential units serve smaller spaces. Commercial systems have multiple pipes and pans for draining that ensures absolute evaporation to rid a likely overflow.



With commercial systems, all parts are housed together and it only needs simple maintenance while with residential systems, all the parts in between the inside and outside cannot be modified.



The HVAC equipment in residential buildings varies significantly as in comparison with the large HVAC equipment in commercial buildings. These commercial air conditioning units are very efficient un heating and cooling and are very powerful.



As commercial systems are tailored for more complex use, maintenance is higher compared to residential air conditioning units. Commercial air conditioning units need more highly-skilled technician to ensure accurate installation, maintenance and repairs.
