Craig and his team have just fitted 3 aircon units into our clinic in Horsham, West Sussex. Very nice clean job. The units are great and will make our work more comfortable. I would happily recommend this company to carry out a professional job. Many thanks.

We had a very old unit in our office it was hard to find a company that was not only interested in massive jobs we tried a few companies who were just so un helpful because we only needed one new unit this company made me feel as important as any other job they quoted fair and fitted the new system within the time limit requested they are going to service our system every 6 months as requested and I have no doubt they will deliver a great service.

Why Mechcool for your air conditioning installation?

Energy-efficient systems

The majority of the systems we install have an energy efficiency rating of A+ and take care of all heating and cooling needs. We are always upfront about the lifetime air conditioning cost of an installation and recommend the best approach to meet your long-term goals.

Latest technology and aesthetics

Using the most up-to-date advancements in air conditioning technology, our team ensures your system will not only keep you comfortable but do so efficiently and economically. More than just technical experts, we understand aesthetics and how an air conditioning unit will fit into the style of your home.

Comprehensive tests and warranty

Once we have installed your air conditioning unit, we run comprehensive tests to ensure it is functioning correctly and give everyone responsible for operating the units a full walkthrough of the controls. Even after handing over the system, we are always available to answer questions by phone and will come out to take a look if you have a problem.

Air conditioning installed for large projects

If your installation forms part of a major project, we work with building and engineering contractors, architects, and other specialists throughout the whole process to complete project objectives within the required timescale.

Customers often turn to us for our expert knowledge of air conditioning installations, so we provide practical feedback on design proposals and make recommendations about specific technical points.

air conditioning maintenance

Understanding your legal responsibility

It is now a legal requirement that the owner of an air conditioning system ensure leak checks are carried out at least once a year on any plant that contains more than 3 kg of refrigerant.

You also need to keep a record of all leak checks to show that these have been carried out by an engineer who holds a current refrigerant F gas handling licence. All Mechcool F gas clients are on our record system to ensure peace of mind.
