Guide to Purchasing a cloak Conditioning Installation - Commercial or residential


Buying an aura conditioning installation package in the UK can be a difficult decision for the majority of business, building or home owners. There are various manufacturers, different system types and lots of factors to take into consideration, not simply the bottom line price of the original installation.

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


An expert air conditioning installation company can provide a quality design service, proclaiming to offer you 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. In fact I think this would be anyone's minimum requirement if they're about to spend a great deal of money, but you will be surprised how many companies don't supply this focus on detail.

A design must take into account the following factors:

1. Air conditioning loads of the room/s.
2. Venting distribution to maximise comfort for your occupants.
3. Ease of installation to maximise speed of installation for minimal disruption and system cost.
4. Price of the system to match the client's budget.
5. Running costs, including simple maintenance and electrical consumption.
6. System type to meet the requirements.

A comprehensive quotation must be provided, detailing the following:

1. Design requirements.
2. The scope of works.
3. The gear supplied.
4. Installation time.
5. Warranty with the installation and the equipment.
6. Exclusions, works etc that are not supplied.
7. Price.
8. Payment terms.
9. Contractual information supporting both sides.
10. Technical information for equipment and materials.


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

1. The standard of the installation is very important, top line equipment and installation materials should be used, as well as a professional installation by qualified & experienced engineers who work coming from a detailed design to industry standards to a quality assurance level as quoted from the installation company. If you pay bottom price, you normally get bottom quality, air conditioning companies need to make profit as with all other business! Often there is a balance though so you shouldn't be afraid to discuss this using the installer.

2. Running charges are the most important aspect to consider when designing or buying an air conditioning installation. Why? As it cost's around the same to own it over its lifetime because it does to purchase the installation!

3. If your design of the installation is wrong, the device will not work properly, meaning it'll run and run, using up electricity, costing you something for 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 net profit costs influencing decisions can be seen where a single indoor ac is installed whenever a twin indoor unit is needed. The single is cheaper to get than the twin, less labour to setup, equipment and material costs. The installer quotes the least expensive price possible with the poorest (unknowingly to the client) quality installation and the client see's a saving and accepts the quote. You will get complaints of warm and cold spots within the room, people are uncomfortable, running pricing is sky high, the unit reduces and nothing can be done but start again which is not on the clients agenda and budget for a solution to a problem that can of been resolved from the design and tender stage.

If the twin system was accepted, in a higher bottom line cost, the machine would work comfortably, occupants would be comfortable, no cold or 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 very important to a satisfactory air cooling design and installation solution. You have air conditioning to make an atmosphere comfortable, so it doesn't be the better choice to buy air conditioning when it will make the occupants un-comfortable. A snug 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 in the indoor unit's in a temperature from 0 to twenty degrees Celsius, depending on the outdoor ambient temperature including 20 to 40 degrees Celsius. The indoor air off temperatures are relevant to the outdoor ambient.

Air conditioning works by the indoor unit absorbing the heat via a heat exchanger, not by blowing cold air in to a space. You must however, design a system that provides air flow right places, this air should then go back to the unit as it has absorbed the force or heat via a flight.

I am yet to get someone who can sit in the office all day under a single air conditioning unit that blasts 0 to 5 degree air onto them at a rate like a desk fan would, it is simply not very comfortable in any way! The best way to combat this can be to use a ducted unit, place the up to four ducts on a ducted unit, each duct features a diffuser grille that blows the environment out 360 degrees at ceiling level, at the nice and slow rate allowing it to gently & comfortably collapse onto the occupants which supplies the comfort level you require at a budget both installer and client find acceptable.


Method are extremely technical. Systems really are a combination of electrics and plumbing on the high end scale. The systems have grown to be extremely efficient and provide more possibilities than others.

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

1. Wall unit, quickest and cheapest to setup.
2. Cassette unit, common in offices, set up in suspended ceilings.
3. Ducted unit, the most expensive per unit nevertheless the most comfortable and energy efficient.

There are several different types of outdoor units, these are as follows:

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

You will need to understand what system you desire or what you are getting. Using this method you can compare quotes in case you went to multiple suppliers, then you can certainly make an intelligent decision depending on some technical knowledge


Maintenance is essential because it allows the unit to be effective as it should, 100% efficiently. In the event the filters and heat exchangers are blocked, it does not work as efficiently as it might do, sometimes as much as 50% less. The unit will then develop problems and cost money to fix it via breakdowns and excessive electrical consumption.

Standard maintenance is provided for each winter and summer season, so two visits per year. A decent air conditioning company are able to undertake this work, supply you with a maintenance contract and also have some quality assurance that's applicable to a good maintenance strategy.


Any purchaser of air-con should assess the energy utilization of the system they require or continues to be quoted as a solution. Energy labelling sometimes appears on consumer goods like washing machines, tumble dryers and dishwashers. Exactly the same applies to air conditioning units.

Air conditioning 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. Put simply, they give off 3.5kw of cooling and 4kw of warmth to 1kw of electricity.

All systems have different EER and CoP, it depends on the type of manufacturer, the type of system and the configuration. The supplier are able to provide the EER and CoP inside technical details from the quotation.


We all have an obligation to carbon emissions reduction and to reduce them where we could. 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.

Don't be the product, buy the product!
