Energy Efficient Heating and Cooling Systems

DMAC Group provides energy efficient heating and cooling systems to businesses, industry, and homes. We aim to provide our clients with a first class service that puts you at the heart of everything we do, right from when you first contact us, to the installation of your air conditioning unit, and to any after-care support you may require.

We specialise in server room applications and R22 replacements and strive to fit the systems quickly and efficiently. Our engineers receive the most up to date training available to ensure our clients receive the most efficient and effective service.

As a supplier of heating and cooling systems, we understand that one of the most important factors our clients consider when choosing their system is how much their energy costs will be. We also understand that even though our clients want affordable energy costs, they also want high-quality systems. DMAC Group’s A ++ energy rated systems do both.

What our Customers Say...

  • Darryl was very helpful and friendly. He clearly explained what was the best option for house and provided a detailed quote. All the work was planned at our convenience. The work was done to the highest standard and we felt included in all the decision making. Thank you for your hard work.

  • As a chef I strive for perfection so recently I have been lucky enough to take on my own restaurant which needed extensive refurbishment so with this brings many hidden issues. You need to trust and rely on your tradesmen to be specialists in there field and Darryl Mills certainly was. Darryl not only did an exceptional job installing the air conditioning units but also gave me advice and support in other areas throughout the project and I can't thank him enough. Thanks again Darryl

  • We have had an air-con installed in our conservatory and we're delighted with the service. The job was done cleanly and efficiently - the conservatory was left clean and tidy at the end of the job. On top of all this, the after-sales service was brilliant; we were made to feel 100% happy throughout the process. We are so impressed. Thanks Daz! we are planning on adding more air-conditioners to our home.
