The installation of a heat-pump was done on the day and time agreed.The installation team were professional and very competent, who quickly and proficiently explained the "ins and outs" of the job, and guided us to the most appropriate setup. They did a very neat and tidy job. And, they were a very nice couple of guys as well.I highly recommend the whole Chillmax team (not only the install folks). They've all been a pleasure to do business with.
