”We recently had an F Gas Audit which we passed with flying colours, thanks mainly due to the meticulous records that the Barrier Engineers maintain on site. I am also impressed with the health and safety elements, general record keeping, and also the service visit and call out reports. Our regular engineer is diligent, hardworking and cheerful. All of your engineers are technically very competent, professional and courteous. Thank you for your work over the past year.”

 “Barrier has been St John Ambulance London District’s chosen supplier for air conditioning maintenance solutions for many years. We regard ourselves to be very fortunate to have found such a reliable and responsive supplier. Barrier has provided us with recommendations in relation to our air conditioning requirements, including how to reduce our energy consumption and cut costs. I have no hesitation in recommending Barrier Air Conditioning Ltd to any organisation.”

Deputy Chief Executive (St John Ambulance)

 “Your engineers were very professional and very careful with regard to noise, keeping areas clean and the protection of furniture. Thank you for your help. I would like to recommend your Company to Head Office for the whole of our Group”


“Even with all the hot weather experienced recently, we have encountered very little disruption to the operational performance of the a/c units within our client data centres etc… It is a testament therefore that the regular a/c preventative maintenance works, the pro-active tasks to check and leak test suspected AHU units have proved most successful and effective.”

Site Facilities Manager (Disaster Recovery)

“We have been customers of Barrier AC for the past 15 years. Great local Company. Their engineers always work professionally and unobtrusively in our busy Vetinary Practice.”
