What our clients say?

I contacted ACS and initially hesitated because they quoted a better price for a higher quality product than the competition. I had an initial survey done by ACS and then a follow up review to make sure what was quoted was fully implementable. They were very flexible on scheduling the installation and worked around my hectic timetable. Their work was efficient, clean and very tidy. I had a few complications in my flat, which Mark worked around and resolved. The team never complained about my scheduling and even worked a very long day to complete the works. My family is overjoyed at having the a/c, so I’m satisfied.
