Guide to Purchasing an aura Conditioning Installation - Commercial or



Buying an air conditioning installation package in england can be a difficult decision for some business, building or home owners. There are various manufacturers, different system types and many factors to take into consideration, not merely the bottom line price of the original installation.

The following details will enlighten one to what you need to consider before you go ahead with an air cooling system installation within your office, retail shop or commercial building. Please keep to the links to get further information to support this article in great detail if you so wish.


An experienced air conditioning installation company will provide a quality design service, promoting with the ability to understand what you are receiving. A comprehensive quote will be supplied which will detail what exactly you are getting and why. After all I think this would be anyone's minimum requirement when they are about to spend a substantial amount of money, but you will be blown away how many companies don't supply this awareness of detail.

A design have to take into account the following factors:

1. Cooling and heating loads of the room/s.
2. Venting distribution to maximise comfort to the occupants.
3. Quick and easy installation to maximise speed of installation for minimal disruption and system cost.
4. Tariff of the system to match the client's budget.
5. Running costs, including ease of maintenance and electrical consumption.
6. System type in order to meet the requirements.

A comprehensive quotation needs to be provided, detailing the following:

1. Design requirements.
2. The scope of works.
3. The apparatus supplied.
4. Installation time.
5. Warranty of the installation and the equipment.
6. Exclusions, works etc that aren't supplied.
7. Price.
8. Payment terms.
9. Contractual information supporting both parties.
10. Technical information for equipment and materials.


This is always the main consideration for almost any business for an air conditioning installation, but the initial expense is not the only cost you should consider. This mistake can cost you dearly down the road down the line. The following must be addressed and understood to help you the important long term savings:

1. The grade of the installation is very important, top line equipment and installation materials ought to always be used, as well as a professional installation by qualified & experienced engineers who work from a detailed design to industry standards to some quality assurance level as quoted with the installation company. In the event you pay bottom price, you normally get bottom quality, air cooling companies need to make profit services or products other business! There is always a balance though so avoid being afraid to discuss this with the installer.

2. Running expense is the most important aspect to consider when making or buying an air conditioning installation. Why? As it cost's around the same to perform it over its lifetime since it does to purchase the installation!

3. If your design of the installation is wrong, the device will not work properly, meaning it's going to run and run, burning up electricity, costing you something absolutely free and also increasing your carbon emissions. Also, the more a system works, the more breakdowns you are likely to get, so damage limitation is essential.

Typical examples of bottom line costs influencing decisions are commonly seen where a single indoor air conditioner is installed every time a twin indoor unit is needed. The single is cheaper to acquire than the twin, less labour to setup, equipment and material costs. The installer quotes the most affordable price possible using the poorest (unknowingly on the client) quality installation and also the client see's a saving and accepts the quote. You will get complaints of warm and cold spots space, people are uncomfortable, running prices are sky high, the unit reduces and nothing can be done but start again which is not on the clients agenda and afford a solution to a problem that could of been resolved from the design and tender stage.

If your twin system was accepted, with a higher bottom line cost, it would work comfortably, occupants can be comfortable, no hot spots and a generally more professional installation will mean limited breakdowns if any at all (as long as they are maintained annually).


The comfort of the occupants is important to a satisfactory air conditioning design and installation solution. You have air conditioning to make a breeding ground comfortable, so it doesn't seem sensible to buy air conditioning if it will make the occupants un-comfortable. A cushty temperature range for humans is 21 to 25 degrees Celsius, 21 for men, 25 for females with 23 the typical I advise as the recommended set temp.

Air conditioning systems will provide air through the indoor unit's with a temperature from 0 to 20 degrees Celsius, depending on the outdoor ambient temperature which range from 20 to 40 degrees Celsius. The indoor air off temperature is relevant to the outdoor ambient.

Air-con works by the indoor unit absorbing heat via a heat exchanger, not by blowing cold air into a space. You must however, design a process that provides air flow to the correct places, this air should then return to the unit as it has absorbed the force or heat in mid-air.

I am yet to get someone who can sit in a office all day within single air conditioning unit that blasts 0 to 5 degree air onto them for a price like a desk fan would, it's just not very comfortable whatsoever! The best way to combat this really is to use a ducted unit, you can put up to four ducts on the ducted unit, each duct features a diffuser grille that blows air out 360 degrees at ceiling level, with a nice and slow rate letting it to gently & comfortably fall down onto the occupants which provides the comfort level you might need at a budget the installer and client find acceptable.


Method are extremely technical. Systems are a combination of electrics and plumbing on a high end scale. The systems are getting to be extremely efficient and gives more possibilities as opposed to runners.

There are many different types of indoor units, they may be as follows:

1. Wall unit, quickest and cheapest to put in.
2. Cassette unit, common in offices, installed in suspended ceilings.
3. Ducted unit, the priciest per unit nevertheless the most comfortable and energy efficient.

There are many different types of outdoor units, they are as follows:

1. Single split system.
2. Multi-split system.
3. VRV System.

It is important to understand what system you would like or what you are getting. Using this method you can compare quotes in case you went to multiple suppliers, then you can make an intelligent decision based on some technical knowledge


Maintenance is vital because it allows the unit to work as it should, 100% efficiently. If your filters and heat exchangers are blocked, it will not work as efficiently as it might do, sometimes approximately 50% less. The unit will develop problems and value money to fix it via breakdowns and excessive electrical consumption.

Standard maintenance is given for each winter and summer season, so two visits annually. A decent air conditioning company will be able to undertake this work, provide you with a maintenance contract and have some quality assurance which is applicable to a good maintenance strategy.


Any purchaser of air conditioning should assess the energy use of the system they require or has become quoted as a solution. Energy labelling is seen on consumer goods like washing machines, tumble dryers and dishwashers. Precisely the same applies to air conditioning units.

Air conditioners have a electrical efficiency rating or EER in cooling plus a co-efficiency of performance CoP in heating. Air conditioning standards are typically an average of 3.5 EER and 4 CoP. To put it differently, they give off 3.5kw of cooling and 4kw of warmth to 1kw of electricity.

All systems have different EER and CoP, this will depend on the type of manufacturer, the type of system and the configuration. The supplier can provide the EER and CoP inside the technical details inside the quotation.


All of us have an obligation to carbon emissions reduction and reduce them where we can. Saving on electrical consumption doesn't just save you money, but reduces your carbon emissions. There are numerous products, services and options to consider to reduce both electrical consumption and carbon emissions.
