Air Conditioning Installation & Repair Hertfordshire


As with every commercial air conditioning system, it’s important that regular maintenance is carried out and that this preservation is viewed as an investment in your key assets rather than as an ongoing expense.

If you’re looking for an air conditioning maintenance package where you receive scheduled service visits throughout the year, then AirCare is definitely for you.  Our system ensures that all your indoor air quality improvement systems are running correctly, providing premium air quality, and keeping you f-gas compliant.

The reasons that you should ensure the maintenance of your systems fall into three main categories:

  • Your people. It is important that your people have an environment that is clean, making it imperative that your HVAC equipment receives regular maintenance and is kept in prime working order.
  • Your Air Quality Improvement Assets As An Investment. Maintaining your capital equipment will ensure that it delivers optimum performance over a longer period of time.  
  • Your Bottom Line. All our air-conditioning maintenance packages, and air conditioning maintenance contracts are built with you and your budget in mind.

It is proven that the right air conditioning, heating, and ventilation in spaces help to create an area that boosts efficiency, protects employees’ health, and maintains comfort.

At Salix, we work with you and with your budget to create a solution that is right for you.
