Very likely, your team arrived on time. They worked quickly and efficiently, plus they were very friendly. They left our house as they found it , clean and tidy. Just one thing they left behind a piece of equipment which I'm sure they can use. It is no use to us, so it would be a shame to throw it out. Many Thanks.

Ray did an excellent job. As it turned out, the error that caused the problem was cleared when the power was off after the storm, but he still made sure the system was working properly by doing a really thorough check of everything.

We would have liked to be given the option whether to have the smelly chemicals sprayed in the split systems, as the smell lasted for over a week and we would have opted not to have that. Otherwise we are very happy with the overall service and communication from the technician.
