Air Conditioning & Ventilation in Hertfordshire

Indoor air quality improvement systems create the comfortable, safe environments for working, learning, living, and storage that we have come to rely on.

Design and Installation


Properly ventilated spaces maintained at a constant, year-round temperature and humidity improve the alertness and cognitive skills of workers and students and encourage footfall in commercial properties such as retail outlets, sports centres and entertainment venues.

They also prevent the accumulation of odours, dust and bacteria that are harmful to health and cause products to deteriorate. Refrigeration systems prolong the freshness of produce and are essential for storing temperature-sensitive products such as vaccines and other medical substances.

Located in Hitchin, Salix is the perfect choice for indoor air quality improvement system design, supply, installation and maintenance services throughout Hertfordshire.

We know that efficient systems start with proficient design and rely on professional installation, which is why we entrust each project to our own team of design engineers and installers.

Our design and installation projects across Hertfordshire have been for a wide range of sectors, including:

Maintenance and Repairs


While our air conditioning systems offer outstanding build quality and operational reliability, no system is a fit-and-forget investment. Regular, scheduled maintenance will keep it operating at maximum efficiency and

  • prevent unnecessary or premature wear or faults
  • ensure compliance with regulations
  • keep your workforce healthy, safe and productive by reducing or removing airborne bacteria and pollutants
  • maintain product quality, freshness and effectiveness

As accredited installers and maintenance partners for leading HVAC brands, we can ensure your manufacturer’s warranty remains valid and up to date, and our preventive maintenance packages are competitively priced and offer peace of mind to busy facilities managers and property owners.

If you’re still running a system that uses fluorinated refrigerant gas, this presents a potential environmental hazard as such gases are known to deplete the ozone layer. We are qualified to conduct the annual inspection required by law to check the system isn’t leaking refrigerant gases into the atmosphere.

Even if your equipment comes from another manufacturer, we still offer a 24/7 breakdown service across Hertfordshire with a 4-hour response callout time. You don’t even need to be on one of our service and maintenance contracts to be quickly operational again.

Do you have a refrigerant system that needs repairing?  Contact us to discuss more about our commercial refrigeration maintenance service.


Ventilation and Sanitisation


While some air conditioning systems draw in fresh air from outside, others only filter and recirculate the same stale air inside a building.

Ventilating indoor spaces with fresh air is a proven way of improving health quality by reducing the spread and accumulation of viruses and harmful bacteria.

Incorporating our UV-C ultraviolet air sanitation within new or existing air conditioning, ventilation and air handling systems will offer even greater protection against viral and bacterial contamination, creating an environment where harmful organisms cannot reproduce and will quickly die off.

Another highly effective line of defence against viral and bacterial contamination is our AirCare micro-fumigation service for ventilation ductwork and air conditioning filters – areas where organisms are prone to colonise and easily disperse as airborne particles.

Using completely safe and non-corrosive disinfectants that destroy all known viruses and 99% of bacteria and fungi, AirCare can also be used on most interior surfaces during the fumigation process, extending its effectiveness.
