Residential Air Conditioning

Fixed air conditioners have become common in many homes in the UK. They keep you comfortable throughout the day and can significantly aid sleeping at night through hot spells. The home air conditioning units we install are extremely energy efficient and whisper-quiet. 
When selecting an home air conditioners, there are many factors to take into consideration. The number of rooms, dimensions, layout and aesthetics are all important as well as the cost implications. Manufacturers have worked hard to create a wide array of models and systems that look very aesthetically pleasing in the home, and some units can seem virtually invisible in a room.
We provide a free site survey no matter how big or small the job. All surveys are carried out by our experienced aircon engineers who can tackle even the toughest of domestic air conditioning installations.

Commercial Air Conditioning

Air conditioning in the commercial environment is now seen as standard for modern developments and in recent years, demand for retro-fitted air conditioners in existing business premises has skyrocketed.
A pleasant, cool environment is something that customers have come to expect in shops and restaurants. A moderate temperature also creates the ideal environment for consumers to spend more time and, accordingly, more money. In offices, staff are far more productive when they don’t have to worry about being sweaty in the summer or icy-cold in the winter.
There has also been a large increase in the number of schools installing air conditioning as students often perform better, especially in exam situations, when they are in a comfortable environment.
Having been in the air conditioning industry for over 10 years, we’ve seen it all and worked in thousands of business locations all over London and the Home Counties. Our engineers are highly experienced and our dedicated customer support team will provide you with all the attention and assistance you require. We only employ qualified, experienced air conditioning engineers who will always treat your business with the utmost care and attention.

Ozone decontamination

Completely remove bad odours from your house, car or business in less than an hour.

High ozone shock treatment or ozone blasting is a process for removing unwanted odour, and killing mold, vermin and microorganisms in commercial and residential buildings. The treatment is less expensive than some alternative methods of sterilizing indoor spaces - cleaning or removal of building material, or in extreme cases the abandonment of sick buildings.

High ozone shock treatment involves using an ozone generator with a timer to create lethal levels of ozone in an enclosed odour ridden or mold-affected room or building for a short period of time, between one and several hours. For safety reasons, the affected area must be evacuated of people, animals and live plants for the duration of the exposure, and for a long enough period afterwards to allow the ozone to dissipate.

 

Vehicle air conditioning systems

Air conditioning systems in vehicles work in the same way asy anysystem in a building, only at a smaller scale. So like in buildings, such installations also require regular checks.
Car installations often require re-gasing as contstant vibrations occuring during driving may cause a refrigerant leak.

Ventilation

We specialize in commercial kitchen air extractors and canopies.

 

Here at RSI we provide our customers with the best ventilation systems for all premises. Our experts will take care of the design and installation of your new system to ensure that every element of the process reaches our own exacting standards.

We work with the leading suppliers and manufacturers of heat recovery, extraction fans, fresh air ventilation and evaporative cooling systems in the world to deliver perfect ventilation for domestic and commercial environments.

RSI can offer:

  • Experienced Ventilation Engineer

  • HVAC Installation and Maintenance

  • Ventilation Installation

  • Ventilation Maintenance

  • All Types of Ductwork

  • MVHR Systems

  • All Ventilation Systems Service

  • Ventilation Repairs

  • Heat Recovery Ventilation

  • Thermal and Acoustic Insulation

  • Ventilation Services

Heat recovery ventilation (HRV), also known as mechanical ventilation heat recovery (MVHR), is an energy recovery ventilation system using equipment known as a heat recovery ventilator, heat exchanger, air exchanger, or air-to-air heat exchanger which employs a cross flow or counter-flow heat exchanger (countercurrent heat exchange) between the inbound and outbound air flow. HRV provides fresh air and improved climate control, while also saving energy by reducing heating (and cooling) requirements for many applications including vehicles.
As building efficiency is improved with insulation and weather stripping, buildings are intentionally made more airtight, and consequently less well ventilated. Since all buildings require a source of fresh air, the need for HRVs has become obvious. While opening a window does provide ventilation, the building’s heat and humidity will then be lost in the winter and gained in the summer, both of which are undesirable for the indoor climate and for energy efficiency, since the building’s heating, ventilating/ventilation, and air conditioning (HVAC) systems must compensate. HRV introduces fresh air to a building and improves climate control, whilst promoting efficient energy use.
UK building regulations require one air change every two hours (0.5 ACH). With traditional extract-only ventilation that means a house boiler would need to warm up a house-full of cold air 12 times a day.
