Read our Commercial Air Conditioning FAQ’s

If you are a business or have a commercial property and you have or are thinking about installing or updating your Air Conditioning then our Commercial Air Conditioning FAQ’s will help.

What is Commercial Air Conditioning?

Commercial Air Conditioning is used to cool, heat and dehumidify the air in small to large commercial properties. Commercial Air Conditioning systems can be used in offices, shops, cafes, restaurants, schools, leisure centres, gyms and any type of commercial property to keep the temperature and quality of air at it’s optimum and to ensure customers and/or staff keep cool in the summer and warm in the winter.

An air conditioning system will take the air from inside space and can heat or cool it to the temperature you have set it to. It will then recycle the same air back into the room to maintain the temperature.

Air conditioning can be referred to as AC, A/C, or air con. There are many different systems on the market with different heating and cooling capacities and settings so it’s always important to ensure you get a professional commercial air conditioning businesses to support you to ensure you choose the most suitable system for your business and property.

Most commercial air conditioning units circulate a compressed gas, known as the refrigerant in a closed split system which cools the air down as well as the air inside the unit being condensed. The outside air is the medium used by most units when the refrigerant is re-cooled and condensed.

Why is Commercial Air Conditioning different from Domestic Air Conditioning?

Air conditioning can be used in both domestic and commercial properties. The major difference between cooling a commercial space and cooling a home is the amount of power needed and how much the system will be used. Sizing an air conditioning system for a commercial space needs a high level of technical skill and experience to ensure the installed system provides the right level of BTU’s for cooling, without draining power or short-cycling. BTU’s (British Thermal Unit) measures the quantity of heat a conditioning unit can remove from a room per hour.

How does Commercial Air Conditioning work?

An air conditioning unit collects air from a given space, processes it within itself with the help of a refrigerant and coil system and then releases the cooled air back into the same space where the hot air has originally been collected from.

What types of Commercial Air Conditioning Systems are there?

  • Central Air Conditioning
  • Ductless, Mini-Split Air Conditioner
  • Window Air Conditioner
  • Portable Air Conditioner
  • Hybrid Air Conditioners
  • Geothermal Heating & Cooling

How do I know which Commercial Air Conditioning System to Choose?

Every Air Conditioning System has a BTU (British Thermal Unit) rating which indicates the amount of heat it can remove from a room. When you are looking at Air Conditioning Systems, the square footage of the room you want to cool has to be determined (by multiplying the length of the room by its width) and compared to the BTU to establish if it has the cooling capacity needed. Another factor to take into consideration is if you also want the system to heat the areas as this will make a difference to the system you choose.

Experienced Air Conditioning Installers will measure and specify the size and make of the air conditioning unit you will need for your specifications. The performance of commercial air conditioning units will vary, depending on increased static air pressure and internal coil sizes. The bigger the area, the height of the ceilings, number of people and other systems in an area will impact the internal fans and coils required to cool or heat the space, so it is really important to use a professionally qualified air condition engineer or company to help you plan and install your system.

If you haven’t had your system serviced recently then search for a business that has the qualifications, experience and offers regular maintenance visits.

What is an HVAC System?

HVAC System stands for Heating, Ventilating, and Air Conditioning (HVAC). These systems are used for heating and cooling the air in residential, commercial and industrial properties.

How does HVAC Air Conditioning Heat and Cool the Air?

A compressor converts refrigerant from a gas to liquid and sends it into the coils of the system. Refrigerant runs through HVAC coils, usually located in the outdoor unit, cooling and heating the air as it passes through. It is one of the most important factors for maintaining the acceptable indoor air quality in buildings and is most commonly used in commercial properties.

How will an HVAC help my building or business?

An HVAC system will maintain the temperature of your area at the heat setting you need, whether its to cool the area or building in the summer or warm it in the winter.

What is the difference between a Commercial Air Conditioning System and an HVAC System?

AC is short for air conditioning, HVAC is short for heating, ventilation, and air conditioning. The two systems tend to be used interchangeably to describe any air conditioning or heating device, whether it’s a window unit or a central system. An Air Conditioning system only cools the air versus an HVAC system which will heat the air as well.

What is the best Commercial HVAC System?

There really isn’t a ‘best’ HVAC system as it all depends on your requirements, your property size as well as its layout. A good air conditioning engineer will be able to advise you on this, as well as the benefits and disadvantages of each system and brand.

Does a Commercial Air Conditioning System purify the air?

Air conditioners are beneficial as they help circulate and filter indoor air. This can help reduce indoor air pollution especially when the air quality outside is poor. It is important that air conditioning systems are regularly cleaned and maintained so it works proficiently to filters the air as it enters the room as well as maintain the temperature. If you don’t get a system serviced and maintained its performance and effectiveness will decrease over time.

How do you maintain a Commercial Air Conditioning System?

There are many moving parts in an air conditioning system so it is important they are checked, serviced and cleaned a minimum of once a year to keep them fully optimised and to prevent issues, as these normally arise when you are relying on your system most for cool or heated air in the summer or winter months.

Why should I have my Commercial Air Conditioning System Serviced?

An air conditioner’s filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance results in a steady decline in an air conditioning systems performance and its energy use will steadily increase as it has to work harder to cool or heat the air.

HVAC Systems are most commonly used to cool and heat larger buildings. Their compressors compress the refrigerant, increasing its pressure and temperature and hot outside air is blown over the refrigerant vapour by the condenser to liquefy it. The expansion valve then changes the refrigerant into a low-pressure liquid, thus cooling it.
The air conditioning system you need is defined by the size of your room as well as ceiling height and other systems you have in the space. An experienced and qualified Air Conditioning company will meet with you to discuss your requirements, assess your area and then plan and design your air conditioning system, offering you recommendations of the system that will benefit you most.  

How often should I have my a Commercial Air Conditioning unit serviced?

You should have your air conditioning system serviced annually but this will depend on the usage of your unit(s). You should bear in mind that if an item has more than 3Kg of refrigerant then under the F-gas legislation you are required to have it leak checked by a qualified engineer at least every 12 months.

Why would I consider installing Commercial Air Conditioning?

An air conditioning system will provide a comfortable working environment for your staff and customers. If a working environment is too hot or cold it will impact customers wanting to return as well as having a detrimental effect on your team’s health and well being. It has been well documented and researched that a comfortable environment can lead to a dramatic increase in productivity.

How is Commercial Air Conditioning an environmentally friendly heating solution?

Air conditioning works by taking low-level heat from outside and converting it to usable heat in your property, providing approximately 4Kw of heat for every 1Kw of electricity used.

Good air conditioning installers will be passionate about protecting the environment and working with renewable energy technologies to improve energy efficiency and they should be advising you how you can reduce your energy consumption.

What is the best Commercial Air Conditioning System?
