Frequently Asked Questions
An air conditioning product will only cool the room temperature. Climate control will not only cool but also heat and so can maintain your preferred temperature regardless of the outdoor temperature.
Q: How does climate
control work?
Cooling mode: A special liquid called a refrigerant,
which is sealed within the system, absorbs excess room heat. As the refrigerant
absorbs heat from the room it changes into a gas and passes through small,
copper tubes to an outdoor unit where the heat is released, into the atmosphere.
The gas then changes back into a cold liquid, returning to the indoor
unit where the air is fanned over it and out into the room. This cycle
is automatically repeated to maintain the required room temperature.
Heating mode: Heat pump systems also allow the above
cycles to be reversed. A heat pump extracts "free" heat from
the outdoor air. Heat pump units therefore avoid the need for a boiler
and allow you to cool and heat with the same unit, with savings in cost
and energy throughout the year.
The hot and cold split air conditioning units are suitable for both domestic and commercial uses. They can be fitted in bedrooms, conservatories, offices, port-a-cabins and shops. The main thing you need to be aware of is that you will need an indoor and an outdoor unit of the same BTU rating.
Not as much as you might think a 12000BTU unit would cost approx 6p per hour or an 18000BTU unit would cost approx 9p per hour to run when turned on full power (this assumes a unit of electricity as being 6p inc. VAT).
The size of the unit required is dependant on a number of factors with room size, ceiling height and rooms containing large windows with direct sunlight coming in being just a few of the things to be considered. Our surveyors will assess all aspects of the location for the installation and recommend the correct size unit to ensure that it will be effective and economical to run.
The indoor units are typically less noisy than a standard domestic fan. The outdoor units are slightly noisier than a standard domestic fan.
If your installation is a standard “back to back”, which is where the internal unit is fitted on the same wall directly behind the external unit ( see How does climate control work? for an illustration ), then our engineers will install a units within 3 hours. If the installation requires running additional pipework through rooms then this will obviously take more time. Our surveyors can give an estimated time for the work to be completed when undertaking a survey.
If you do not have the unit serviced then the warranty will not be extended for another year. If you require an engineer to attend outside of the warranty then there will be a set call out charge, an hourly labour charge plus the cost for replacing any parts.
All units come with a 1 year parts and labour warranty which is extended to 3 years so long as an annual service is carried out. We will write to you to inform you that a service is due and the cost per year will cover a full service of the unit and all parts and labour. If you have more than 1 unit there will be an additional smaller cost per extra unit.
The term “back-to-back” is used for installations where the internal wall mounted unit is fixed to an external wall and the external compressor is fitted on the outside wall directly behind (or within 2 metres). This type of installation will not require any additional pipes or a pump resulting in minimal costs for fitting.
Our units are designed to be a maximum of 12 metres from the internal wall unit to the external compressor. For installations that are between 7 and 12 metres there will be a requirement for extra refrigerant gas to be put into the system.
Sqm is the abbreviation for square metres which is used to establish the unit size required for a room. This calculation can be obtained by measuring the length and width of the room and multiplying these sizes by each other. For example a room that is 6 metres wide and 4 metres in length will be 24sqm.
Our largest wall mounted units have a start up requirement of 11.5 amps and run at 7.4 amps. Therefore we only require to take a fuse spur from your existing plug socket supply which is 13 amps.
On residential installations all external pipes are contained inside 70mm x 110mm white plastic trunking. This trunking can be painted with 2 coats of gloss to match any other guttering you may have on you home.
