    Air Conditioning Installation

    Air con installation in lounge & bedroom

    Rob, Kelly and the team were excellent throughout. From coming out to quote, answering my many questions and then installing the air con units. Everyone was friendly and helpful. Everything was installed neatly and they cleaned up fully after everything was done. Highly recommend sub zero!

    We would use sub-zero again, great job done on time.

    Rob was very helpful in helping decide the best options for us during a site visit. We agreed an installation date, they did a neat and tidy job on the date agreed. We would use sub-zero again.

    Exceptional Workmanship

    Sub-Zero Airconditioning Ltd were exceptional from start to finish. Ours was a detailed installation with a very specific brief, and Rob’s attention to detail was unlike anything I’ve experienced before. Every aspect of the project was carefully considered, from discreet pipework routing to protecting our home throughout the works. Alongside Joe, he worked tirelessly, kept everything immaculate and wouldn’t leave until we were completely happy. The standards Rob sets for his business are in a different league and I wouldn’t hesitate in recommending this company.

    Absolute professional

    I think Rob is amazing. He’s very professional and the effort he puts into something when it doesn’t work is next to none. I will keep on using him for my business and my family members. On a positive note, his air conditioning unit is keeping me cool in this warm weather

    Efficient air con installation

    After the initial meeting I was given 3 quotes with information so I could choose my preferred air con units. Air con units were installed efficiently and with no mess. Full explanation on how to operate the system was given. Really happy with the work carried out and I would recommend Rob and his team.
