Chris was knowledgeable, friendly and professional. Good communications. He explained in detail what he was going to do and why, any alternatives worth considering, and how long it would take to complete the job.
We came across a few hurdles with a very old system, some of which was inaccessible, but Chris managed to figure out a good workaround and my heating was up an running in a short time. Prices were very competitive.
I’ve had to call Chris out twice subsequently to sort out problems with my old system (NOT due to his workmanship), which he happily did free of charge. Highly recommended.
