Although I never bought a system from EPC (which I later regretted), I got excellent information and help from Craig. I had a faulty system install with a different company and Craig went above and beyond to help me get an independent engineer to assess my system in order to get it fixed. He gave of his time via email and the phone freely and was very knowledgable about heat pump systems and how they should be installed. Should I come across anyone needing a heat pump system installation, I will have no hesitation in recommending EPC based on the customer service I received from Craig. If all companies were so forthcoming and helpful it would be much easier to find someone to trust. I would highly recommend EPC.
