The Right System For You

Not only are all properties unique, but air conditioning systems come in many shapes and sizes, so it takes experience and expertise to know which is the best option. We’ve been specialising in air conditioning for over 13 years, so whether you’re looking to optimise for cost, performance, or style - we have you covered.

Air conditioning technology has come a long way in recent years, and clunky, intrusive units are a thing of the past. Here are a few features you can expect from modern units:

High efficiency = low running costs.
Premium functionality like wifi control.

What Our Customers Say

'Aircon unit in a cinema room'

From the very first contact we had with Protocool all the team went above and beyond my expectations.It was a tricky job but they were always happy to speak to the other trades we had on site to find solutions. The onsite engineers are what I call 'proper gents' nothing too much trouble and a complete pleasure to work with.

'Residential loft AC install.'

The Protocool team were prompt and professional. They kept us informed throughout the process, were very punctual and finished the work on the agreed time. I would recommend Protocool.

'8 unit AC installation.'

We use ProtoCool Ltd on a commercial basis for routine and reactive works.  Quotes are issued promptly and dates made available quickly.  The engineer arrived on time and undertook all works as expected.  Site left clean and tidy.  Additional advice also offered about how some of our units may operate more efficiently but no pressure to accept any further work.

'2x A/C systems.'

Very pleased with the consultation process kept informed and team that fitted A/C were excellent.

'Yearly service/Check'

Very pleased with the installation two years ago - the outdoor unit is very quiet in operation, the internal units look nice, are efficient and quiet in normal operation - this was the 2nd yearly service/operational check and filter clean - this is thorough and gives peace of mind - ensuring the system continues to work at peak efficiency - I have no hesitation in recommending Protocool.

'Air Conditioning Service'

Excellent service as always from these guys. Had both my unit serviced, and my dads in the next village. On time, very Clean and most of all very polite. Would not hesitate to recommend Protocool Ltd.

'Annual service of home air conditioning'

After Protocool did such a great job installing my home's air-conditioning in 2019 they were the obvious company to call when the annual service was due one year on - Jack and Josh also provided a professional service in 2020 (on one of the hottest days of the year).

'Residential a/c fitted in two bedroom flat'

The guys did an excellent job, kept everything clean and tidy and turned up on time (even though they were driving a long way). The job was done well within the allotted time and to a very high standard.

'Fitting air conditioner into bedroom'

Very impressed. The service from my first enquiry, through the initial visit to scope the job to the work itself was outstanding. Everyone was polite, professional and very competent. The standard of work was excellent. I am thinking of having air conditioners fitted to other rooms and I will certainly use them again. Highly recommended.
